Opinion of the French Academy of Sciences (8 May 2021): The contribution of nuclear energy in the energy transition, today and tomorrow

 French Academy of Science is the leading scientific authority in France




Texte intégral : https://www.academie-sciences.fr/pdf/rapport/20210614_avis_nucleaire.pdf

Extraits

1) The energy transition: "The energy transition, to be implemented to limit our greenhouse gas emissions and the global warming that results from it, must result in:

- a reduction in our energy consumption per person; - a reduction in our dependence on fossil fuels, primarily coal and oil, and secondly gas;

 - an increase in the share of low-carbon energy sources (renewable energies and nuclear energy); These developments will inevitably lead to a significant increase in the share of electricity in energy production and consumption, reaching a level of around 700 to 900 TWh (terawatts-hour) in 2050, almost double our current electricity production. This electricity must be as decarbonised as possible.

Comment: As the Academy of Technologies had already noticed, this level of 700 to 900 TW.h confirms that the Multiannual Energy Programmation Law  (PPE) must be seriously reviewed. (650 TW.h). As well as all the scenarios, eg @RTE that rely on it.

2) Renewable energies: "Intermittent and variable renewable energies, such as wind and solar photovoltaics, cannot, on their own, supply an electricity grid with power in a stable and controllable way if their random nature is not compensated. This requires massive energy storage capacities and/or controllable backup power generation units. The massive storage of energy, other than that already carried out by means of pumped-storage hydroelectric power stations, would require capacities that are not seen to exist in the coming decades. Pilotability, in the absence of the latter, can only be ensured by nuclear power stations, if we exclude thermal power stations using fossil fuels..

3) Nuclear and CO2  : "A conventional RNT (Thermal Neutron Reactor) massively injects, 24 hours a day, at least for some 300 days a year, decarbonized electricity into the grid. Nuclear power generation is, in fact, of all sources of electrical energy, the least emitter of greenhouse gases (about 6 grams of CO2 equivalent per kWh produced). »

4) Nuclear and environmental impacts :  "A comprehensive life cycle analysis of electrical systems shows that the non-radioactive environmental impacts of nuclear power are most often much lower than those of other systems. As far as radiological impacts are concerned, they remain, in normal working conditions, much lower than those associated with natural radioactivity. On the other hand, those linked to major nuclear accidents have necessitated the evacuation of large areas in order to avoid extraordinary radiological exposures and have had serious social and environmental consequences. Feedback from these accidents has led to successive improvements in reactor safety. Since 2011, EPR-type reactors, third generation pressurized water reactors (EPRs), have been designed to minimize the accidental release of radioactivity into the environment, thanks to technological provisions and more stringent safety regulations

5) Nuclear Waste: "Medium- and high-level waste with a long life, which is the most delicate to manage, has a volume of the order of 1.4 m3/TWh electric for the French fleet (the total volumes of this waste since the beginning of the nuclear era are respectively 42,700 m3 and 4,090 m3). The inventory of all the waste from the French nuclear fleet is regularly updated by the National Agency for the Management of Radioactive Waste (Andra)...

Deep geological storage, under conditions of safety and reversible management, controlled by the Nuclear Safety Authority (ASN), is well suited to long-lived waste. In this context, the application for the creation of Cigéo (Industrial Center for Geological Storage), after twenty years of research by the national scientific community, is ready to be filed with the Ministry of Ecological Transition to be examined by the ASN "

6) RNRs (breeder reactors): From the beginning of the program, the nuclear power policy aimed at the possibility of installing a fleet of fast neutron reactors (RNR) in order to make better use of uranium resources and thus extend the production of nuclear power... The most mature RNR model is a reactor using liquid sodium as the heat transfer fluid for energy: RNR-Na. The feedback from these reactors is important, especially in France, which operated Phoenix, Superphénix and led for 10 years the Astrid project foreshadowing the fourth generation RNR (RNR GenIV).

The Multiannual Energy Programming (PPE) has recently postponed to the next century a deployment of the RNR, leading to the abandonment of the ASTRID project of the CEA. As a standby strategy, it decided to move towards the multirecycling of plutonium from spent fuel in NTRs, particularly EPR reactors. This strategy is intended to maintain France's R&D expertise to move towards the RNRs. It can stabilize the quantities of spent fuel but does not lead to the energy autonomy as sought with the RNR. 

7) Recommendations:

- to maintain the nuclear power capacity of France's energy mix by extending the reactors in operation, when their operation is ensured under conditions of optimum safety, and by building third-generation reactors, the EPRs, in the immediate future. The latter are based on the best technology currently available and offer the best guarantees of safety;

- initiate and support an ambitious R&D program on the nuclear of the future in order to prepare for the emergence in France of innovative fourth generation fast neutron reactors (RNR), which constitute a solution for the future and whose study is actively continuing abroad;

- to take into account in this programme all the scientific aspects of fuel recycling associated with reactors, including the management of radioactive waste;

- maintain training courses to attract the best young talents in all fields of physics, chemistry, engineering and nuclear technologies to develop national skills at the highest level;

- inform the public in full transparency about the constraints of the various energy sources, the complete analysis of their life cycle and the contribution of nuclear power in the current energy transition.

Germans for nuclear energy ?

 A remarkable initiative of the Voices of Nuclear for the inclusion of nuclear power in European taxonomy: 46 environmental NGOs, mainly European and for some foreign to the Union, have called for nuclear power to be taken into account in european taxonomy in the name of combating climate change. This initiative is unprecedented in its scale.

 Cf. Letter to Ursula Von Der Leyen président commission européenne , https://www.voix-du-nucleaire.org/46-ongs-environnementales-demandent-la-reconnaissance-du-nucleaire-dans-la-taxonomie-europeenne/ ; https://twitter.com/voixdunucleaire/status/1376856948872781831

 Among the signatory organizations, 3 Germans. The sign of a change in German public opinion ?

Deutscher arbeitgeber verbank: Liberals in favor of nuclear energy "The German Employers' Association was founded in 1948 when all professional associations were closed by the victorious powers after the Second World War. The main inspiration was Ludwig Erhard, prophet of ordoliberalism. The founders of the association, committed middle-class entrepreneurs and economists, saw the need to free the economy from the clutches of politics and to clearly define and limit the role of the state. So I would say, some kind of liberal think tank.

Positions on nuclear and energy transition:

Ten requirements: start a new energy and environmental policy now!

Energiewende must be abolished now ! : All intermittent green energy (i.e. wind, solar) that are still subsidized by the EEG today must cease to be subsidized and compete in the market - after 30 years of subsidy, they no longer need the "protection of puppies". The addition of new "green" energies may remain permitted, but without a buy-back priority or long-term fixed remuneration. 

 Section 51 of the EEG must be amended so that in the event of negative stock prices of more than five hours, the owners of the system do not receive remuneration, but on the contrary pay a charge equal to the negative prices of electricity. This would effectively prevent the injection of phantom and wasted electricity and limit the priority of powering older systems at times when electricity is worth something. The increase in network charges must also be passed on to wind and solar power plant operators

 The life of the six remaining nuclear power plants will be extended by 20 years guaranteed by an international treaty. They were commissioned between 1984 and 1989 and are still far from reaching the end of their technical lifespan. A majority of the population is already in favour of this solution

 Energy research must once again be oriented in a technologically neutral way... modern and promising developments in nuclear technology must be generously funded.

 The federal government must work to ensure that EU funding rules are changed under the 'taxonomy' and 'green pact' rules so that investments in nuclear technology are promoted or made possible. There are enough EU member states that support the inclusion of nuclear power.

 Damage and opportunity of energy policy: In December of last year, the prestigious National Bureau of Economic Research in Boston published a study on the real costs of eliminating nuclear power in Germany. The authors calculate that the elimination of German nuclear power has cost us about $12 billion a year by 2017. The majority of costs resulted from more than 1,000 premature deaths each year due to higher respiratory diseases due to nuclear elimination and higher electricity exchange prices

 The annual net costs of German energy policy are around 100 billion euros... In 2018: grid charges, which are largely due to the energy transition (17.7 billion), electricity tax 6.6 billion euros (about 0.02 euros. In total, the energy transition alone cost the electricity sector 50.4 billion euros in 2018.

 Other topics: “Nasty fibers” insist on carbon fibers in wind turbines and on the considerable carcinogenic pollution posed by the not-so-rare fire of wind turbines.

 Hydrogen economy: cheap energy sources are needed ! "The central aspect of costs when using hydrogen is the cost of production... nuclear reactors for hydrogen production could also be used in Germany. The construction and operation of nuclear reactors is also permitted after 2022. Article 7 of the Atomic Energy Act prohibits only the operation of nuclear reactors "for commercial electricity production". For the hydrogen economy, nuclear technology could therefore become the gateway to success

Nuklearia: Fighting myths and misinformation

 Nuklearia sees nuclear energy as an essential pillar of energy supply. What for? Because nuclear power is available in far more than enough quantities, 24 hours a day. Nuclear energy requires much less space and land artificialization than wind and solar, and it is providing a baseload....The knowledge of nuclear energy is not sufficiently widespread in the population. Instead of knowledge, there is usually only misinformation or myths... We are working against this misinformation and founded Nuklearia eV for this purpose.

 Nuklearia, via Rainer Klute, seems linked to an evolution of the German Pirate Party in favour of nuclear power

 About Fukushima: "One thing struck me very quickly: what the German media reported was not what I had just learned about nuclear power plants. Nor did it correspond to what NHK World reported or what I was able to look for on the types of Fukushima-Daiichi reactors. And not only the Bildzeitung headlined on "atomic horror", but also the more serious Handelsblatt. Although I had only recently begun to study nuclear energy and radiation, I soon realized that many so-called media experts lacked basic knowledge.

 It pissed me off ! Why did the media do that? Why did they speculate wildly? Why did they play with people's fears? Why did they not provide factual and concrete information about what was happening in Japan?  For me, this has led to a strong will to counter this misinformation in the media with real information. I was a member of the Pirate Party at the time, and there I found like-minded people on nuclear power. In October 2011, we founded a working group within the Pirate Party. »

Position on Nuclear: Nuclear power is part of the Green Deal!

 "This week, 46 environmental organizations around the world, including Nuklearia e. V., sent an open letter to the European Commission. The signatories, led by the French  Voices for Nuclear, are calling for nuclear energy to be part of the European Green Deal and the EU taxonomy for sustainable financing ("EU taxonomy"). The Green Deal is an EU funding programme for green investments with a budget of one trillion euros. The EU taxonomy is a catalogue of criteria that defines which investments in energy supply are sustainable in terms of the environment...

 Rainer Klute, president of Nuklearia e. V. states: "This initiative towards the European Commission fits perfectly into our fight for the preservation of germany's last six nuclear power plants, SaveGER6. If we closed coal-fired power plants instead, it would be by far the most effective and at the same time the cheapest climate protection measure.»


ÖKomoderne: use all available techniques to counter climate change !

"We believe that technologies that other environmental organizations reject, such as civil nuclear energy and green genetic engineering, can make irreplaceable contributions to the prevention of threats such as climate change, ocean acidification, water shortages and soil erosion. The negative aspects of these technologies are often overestimated and not compared to the risks of not using the technology.»


Is there any hope, then, that Germany will question its anti-nuclear folly? We must also recall the initiative of two figures of the German ecological movement, Rainer Moormann and Anna Wendland who published in the Zeit of 20 July 2020 an article entitled: "Stop the elimination of nuclear power! (Stoppt den Atomausstieg!)

(https://www.zeit.de/2020/30/deutsche-klimastrategie-atomausstieg-co2-emissionen-bundesregierung)

  "It makes no sense to keep the lignite power plants that are particularly damaging to the climate and to shut down nuclear power plants... Without long-term electricity storage, the solution is that gas is not climate-acceptable and implies too much dependence on Russia... We must therefore stop the elimination of nuclear power and allow the remaining nuclear power plants to continue to operate for a decade... If the necessary essential progress on the path of large storage had not been made by 2030, the construction of new nuclear power plants should also be considered. »

European taxonomy : the JRC report : Technical assessment of nuclear energy with respect to the ‘do no significant harm’ criteria of Regulation

 Full report : https://lnkd.in/euD-fHb

Other informations of  interest

https://twitter.com/AStrochnis/status/1376834141384290304?s=09 ;https://nitter.tedomum.net/grunblatt/status/1376681091386445826#m

Context : European taxonomy, Green deal, Nuclear waste, the DNSH Citeria, the TEG group, the JRC group

Inclusion or exclusion of nuclear energy in the EU taxonomy was a debated subject throughout the negotiations on the Taxonomy Regulation. While there are indirect references in the regulation to the issue of nuclear energy (including on radioactive waste), co-legislators ultimately left the assessment of nuclear energy to the Commission as part of its work on the delegated acts establishing the technical screening criteria.

The Technical Expert Group on Sustainable Finance (TEG), which was tasked with advising the Commission on the technical screening criteria for the climate change mitigation and adaptation objectives, did not provide a conclusive recommendation on nuclear energy and indicated that a further assessment of the ‘do no significant harm’ aspects of nuclear energy was necessary.

As the in-house science and knowledge service of the Commission with extensive technical expertise on nuclear energy and technology, the JRC was invited to carry out such analysis and to draft a technical assessment report on the ‘do no significant harm’ (DNSH) aspects of nuclear energy including aspects related to the long-term management of high-level radioactive waste and spent nuclear fuel, consistent with the specifications of Articles 17 and 19 of the Taxonomy Regulation.

Conclusion of of the TEG group : No problem for climate mitigation, data lacking on DNSH aspects

Nuclear energy generation has near to zero greenhouse gas emissions in the energy generation phase and can be a contributor to climate mitigation objectives. Consideration of nuclear energy by the TEG from a climate mitigation perspective was therefore warranted….

The proposed Taxonomy regulation and thus TEG’s methodology for including activities in the Taxonomy explicitly includes two equally important aspects, Substantial Contribution to one environmental objective and Do No Significant Harm (DNSH) to the other environmental objective…

Scientific, peer-reviewed evidence of the risk of significant harm to pollution and biodiversity objectives arising from the nuclear value chain was received and considered by the TEG. Evidence regarding advanced risk management procedures and regulations to limit harm to environmental objectives was also received. This included evidence of multiple engineered safeguards, designed to reduce the risks. Despite this evidence, there are still empirical data gaps on key DNSH issues.

For example, regarding the long-term management of High-Level Waste (HLW), there is an international consensus that a safe, long-term technical solution is needed to solve the present unsustainable situation. A combination of temporary storage plus permanent disposal in geological formation is the most promising, with some countries are leading the way in implementing those solutions. Yet nowhere in the world has a viable, safe and long-term underground repository been established. It was therefore infeasible for the TEG to undertake a robust DNSH assessment as no permanent, operational disposal site for HLW exists yet from which long-term empirical, in-situ data and evidence to inform such an evaluation for nuclear energy….

Given these limitations, it was not possible for TEG, nor its members, to conclude that the nuclear energy value chain does not cause significant harm to other environmental objectives on the time scales in question. The TEG has therefore not recommended the inclusion of nuclear energy in the Taxonomy at this stage. Further, the TEG recommends that more extensive technical work is undertaken on the DNSH aspects of nuclear energy in future and by a group with in-depth technical expertise on nuclear life cycle technologies and the existing and potential environmental impacts across all objectives

Comment : Exclusion of the taxonomy would deprive all nuclear project and companies of access to privileged green funding (and also companies working as providers of nuclear companies would be deprived of green financial label). Given the fact that capital cost is a most important part of the cost of new nuclear eg 66% in Hinkley Point), this would really hampers the financing of nuclear project.


Main conclusions of the JRC Group

Conclusion 1) The analyses did not reveal any science-based evidence that nuclear energy does more harm to human health or to the environment than other electricity production technologies already included in the Taxonomy as activities supporting climate change mitigation…

Conclusion 2 ) Presently, there is broad scientific and technical consensus that disposal of high-level, long-lived radioactive waste in deep geologic formations is, at the state of today’s knowledge, considered as an appropriate and safe means of isolating it from the biosphere for very long time scales….Similarly, carbon capture and sequestration (CCS) technology is based on the long-term disposal of waste in geological facilities and it has been included in the taxonomy and received a positive assessment. The Taxonomy Expert Group therefore considers that the challenges of safe long-term disposal of CO2 in geological facilities, which are similar to the challenges facing disposal of high-level radioactive waste, can be adequately managed.

Finland, Sweden and France are in an advanced stage of implementation of their national deep geological disposal facilities, which are expected to start operation within the present decade…

Specific Focus on Nuclear wastes Deep repositories

The fundamental safety objective applicable to all facilities and activities handling radioactive materials is to protect the people and the environment from the harmful effects of ionizing radiation. Thus, the basic and foremost goal of radioactive waste management is to ensure that the radioactive waste materials are contained and sequestered from the biosphere throughout all stages of waste management

For high-level radioactive waste and spent fuel, there is a broad consensus amongst the scientific, technological and regulatory communities that final disposal in deep geological repositories is the most effective and safest feasible solution which can ensure that no significant harm is caused to human life and the environment for the required timespan. The final disposal of spent fuel and radioactive waste in a repository foresees its emplacement in a multi-barrier (engineered and natural) system in a stable geologic formation several hundred metres below ground level. The specific configuration of the repository depends on the characteristics and radioactivity content of the waste. The multi-barrier configuration of the repository prevents radioactive species from reaching the biosphere over the time span required. In the absence of releases of radioactive species to the accessible biosphere, there is neither radiological pollution nor degradation of healthy ecosystems, including water and marine environments…

The safety of deep geological repositories during operation includes active monitoring and control. The long-term safety of radioactive waste in the geological repository, especially after its closure, must not depend on any institutional control and must be based on inherent passive features. Passive features include engineered and natural barriers that do not require continuous supplies to active systems (e.g. electricity), periodic maintenance, replacement of parts, or permanent surveillance. In the case of a deep geological repository for final disposal of spent fuel and high-level waste, the structures of the facility and the natural media must perform their containment functions without external interventions for as long as necessary.

The implementation of a deep geological repository to ensure that radioactive waste does not harm the public and the environment is a stepwise process, which includes a combination of technical solutions and a strong administrative, legal and regulatory framework. Each step is taken based on a documented decision-making process, in which relevant scientific and technical state of the art, operational experience, social aspects and updates in the legal and regulatory framework are incorporated… With the partial exception of the so-called natural analogues (i.e. sites where natural nuclear reactors occurred billions of years ago), there is no empirical evidence generated by a radioactive waste disposal facility that has gone through the pre-operational, operational, and post-closure stages for the entire timeframe foreseen (up to a hundred thousand years or more for a deep geological repository). For this reason the safety of the disposal during the post-closure phase is demonstrated by a robust and reliable process which confirms that dose or risk to the public are kept below the established limits under all circumstances during the time scales of interest and in the absence of direct human monitoring and control…

A variety of tools and approaches is used to provide scientific evidence in support to safe disposal of radioactive waste. Representative waste forms, including real spent fuel and vitrified high-level waste, are studied in hot laboratory facilities to determine the relevant properties and behaviour of the waste exposed to combinations of simulated environmental features. Tailor-made analogues are used to investigate single effects and reactions. The study of natural analogues can yield very valuable information, for example, on the migration of radionuclides across a geological formation. Experiments carried out in underground research laboratories allow acquiring knowledge and data on the properties of the host rock and their impact in the migration of radionuclides. All the experimental data and knowledge are used to develop and validate models using state of the art codes. Modelling is extensively used to understand behaviours and trends observed experimentally and to obtain prediction capabilities for complex systems.

The final disposal of spent fuel and HLW in a deep geological repository foresees its emplacement in a multibarrier (engineered and natural) system in a stable geologic formation several hundred metres below ground level. The multi-barrier configuration of the repository prevents radioactive species from reaching the biosphere over the time span required to fulfil the strict dose limits imposed by the relevant regulations. The individual properties and the combined behaviour of the barrier materials and of the repository environment contribute to delay, block and minimize the release of radionuclides from the waste package, to delay the transport across the engineered barriers, and eventually to reduce and further delay the migration through the geological media (natural barriers). Therefore, all stages of radioactive waste management, including final disposal, do not cause radiological pollution and do not degrade healthy ecosystems, including water and marine environments. The avoidance of significant harm to humans and to the environment is ultimately ensured by the compliance with the regulatory limits set for the radioactivity dose contribution to the nonprofessionally exposed population, which is a pre-condition for the authorization and licensing of any radioactive waste management facility

- The protective function of the final repository against harm caused by radiations is set by relevant regulations. For instance, the time scale for the safety assessment of the Swedish final repository for spent nuclear fuel should cover a period of one million years after closure. The risk criterion set by SSM in Sweden in simplified terms says that people in the vicinity of the repository may not be exposed to greater risks than the equivalent of one-hundredth of the natural background radiation in Sweden today. The Finnish nuclear law states that a final repository under normal operations may not cause a dose to the most exposed member of the public higher than 0.01 mSv/year

- there is worldwide scientific consensus that disposal of spent fuel and HLW in stable geological formations including multiple engineered and natural barriers containing the radioactive waste is the most effective solution to achieve the required long term isolation of radiotoxic substances. The consensus among the experts extends to the conclusion that disposal in a deep geologic repository is technically feasible and that sufficient confidence in the overall safety of geological disposal of spent fuel and HLW has been reached to begin implementation.

- A significant research effort has been devoted to maximising the fraction of spent nuclear fuel that can be recycled in nuclear reactors and reducing the long-term radiotoxicity of HLW to be disposed of in the geological repository. Both aims are relevant to the environmental objective "Transition to a circular economy, waste prevention and recycling". Due to the fact that fast reactors allow multiple (re)cycling of the fractions of fuel/waste not consumed/burned, the final result of iterating this process would be an almost complete use of the fuel and an increasingly reduced fraction of long-lived species (mostly in terms of the minor actinides content) in the irradiated fuel. Although essentially all steps of this process, also known as partitioning and transmutation, have been demonstrated at laboratory scale, the Technology Readiness Level is not yet corresponding to industrial maturity.

Comment :  the problem of nuclear wastesand geological repositories has also been the topic of a very interesting NEA/OCDE report see https://vivrelarecherche.blogspot.com/2020/09/le-probleme-des-dechets-ultimes-du.html, https://www.oecd.org/publications/management-and-disposal-of-high-level-radioactive-waste-33f65af2-en.htm

Safety and health

Safety is ensured  ! The protection of people and the environment in countries with nuclear installations relies on the existence of a solid regulatory framework that oversees the safety and environmental impacts of these installations… The EU and its Member States have developed and established a comprehensive regulatory framework to ensure the safety of nuclear installations, in line with international requirements and recommendations for enhancing regulatory systems for the control of nuclear installations throughout their lifetime. As contracting parties to the Convention on Nuclear Safety and to the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, the EU and its Member States commit to a set of obligations and safety on a global scale, including those relating to their legislative and regulatory framework and regulatory bodies….

Health and Security -Impact of ionizing radiation on human health and the environment

According to the LCIA (Life Cycle Impact Analysis) studies analysed in Chapter 3.4, the total impact on human health of both the radiological and non-radiological emissions from the nuclear energy chain are comparable with the human health impact from offshore wind energy.

The average annual exposure to a member of the public, due to effects attributable to nuclear energy based electricity production is about 0.2 microsievert, which is ten thousand times less than the average annual dose due to the natural background radiation.

The total impact on human health of these radiological emissions, as well as other, non-radiological emissions from the nuclear energy chain, are comparable with the human health impact from offshore wind energy, according to the LCIA …Natural background radiation is responsible for 2.4 mSv/year, or around 78% of the total average annual effective dose to the public of 3.05 mSv/year…

Furthermore, the additional effective doses to members of the public due to the nuclear energy lifecycle are also extremely small when compared to the variations in natural background radiation due to living in different geographic locations…The national averages range from around 1.5 mSv in The Netherlands, to around 6.2 mSv in Finland, a variation of almost 5 mSv/year….


After the Chernobyl accident, there were focused international and national efforts to develop Gen III nuclear power plants. These plants were designed according to extended requirements related to severe accident prevention and mitigation, for example they ensure the capability to mitigate the consequences of a severe degradation of the reactor core, if such an event ever happens. The main design objective was to ensure that even in the worst case, the impact of any radioactive releases to the environment would be limited to within a few kilometres of the site boundary. The deployment of various Gen III plant designs started in the last 15 years worldwide and now practically only Gen III reactors are constructed and commissioned.

These latest technology developments are reflected in the very low fatality rate for the Gen III EPR design10-10 fatalities/GWh,. The fatality rates characterizing state-of-the art Gen III NPPs are the lowest of all the electricity generation technologies.

Other environmental problematics DNSH and pollution : nuclear is better

In accordance with article 17 of the Taxonomy Regulation, an economic activity shall be considered to cause significant harm to pollution prevention and control where:(i) that activity leads to a significant increase in the emissions of pollutants into air, water or land, as compared with the situation before the activity started..

In summary, there is no evidence that nuclear energy does more harm to the transition to a circular economy, including waste prevention and recycling, than other energy technologies included in the Taxonomy.

 Average lifecycle GHG emissions determined for electricity production from nuclear energy arecomparable to the values characteristic to hydropower and wind

 Nuclear energy has very low NOx (nitrous oxides), SO2 (sulphur dioxide), PM (particulate matter) and NMVOC (non-methane volatile organic compounds) emissions, the values are comparable to the emissions of solar PV and wind

 If other impact categories are considered (e.g. acidification and eutrophication potentials), then nuclear energy is again comparable to solar PV and wind ; The same is true for freshwater and marine eco-toxicity; ozone depletion and POCP (photochemical oxidant creation potential

However, with regard to radioactive wastes specifically, clearly nuclear energy produces larger quantities than other generation technologies. For  Radioactive waste and its management –see previous section





water consumption : “While water consumption is very low for once-through cooling, technologies using recirculation cooling, evaporative cooling towers or pond cooling usually consume a significant amount of water to compensate for losses due to evaporation. Water consumption characterizing these cooling technologies remains comparable to concentrating solar power and coal, for both recirculation and pond cooling

General Conclusion

 It can therefore be concluded that all potentially harmful impacts of the various nuclear energy lifecycle phases on human health and the environment can be duly prevented or avoided. The nuclear energy-based electricity production and the associated activities in the whole nuclear fuel cycle (e.g. uranium mining, nuclear fuel fabrication, etc.) do not represent significant harm to any of the TEG objectives, provided that all specific industrial activities involved fulfil the related Technical Screening Criteria.

The nuclear energy-based electricity generation can be considered as an activity significantly contributing to the climate change mitigation objective. Other associated industrial activities in the nuclear fuel cycle (uranium mining & milling, fabrication of nuclear fuel, reprocessing of spent nuclear fuel, final disposal of high-level radioactive waste, etc.) can be treated as activities enabling the safe and sustainable utilization of nuclear energy.

Other considerations :

Influence of mining  : If the whole nuclear life cycle is considered, then uranium mining has large contribution 32%) to the total GHG emission and dominates the following impacts: SOx 88%, NOx 78%, water pollution 91% and land use 68%. Mining is almost exclusively  99% responsible for the potential eco-toxicity and human toxicity impacts and also dominates the acidification, 82%), ozone creation 86% and eutrofication  53%) potentials. Mining does not have significant share in the water consumption, water withdrawal and production of technological waste impacts….Due to the emission of radon, uranium mining is responsible for about 55% of the total gaseous radioactive emissions during the total nuclear lifecycle?

“The final part listed industrial processes and best practices which are regularly used to eliminate or mitigate the potentially harmful impacts of uranium mining and milling. It is demonstrated by the best available technologies of today that by the application of adequate practices the impacts can be controlled and their magnitude can be kept well below the applicable regulatory limits.”

Influence of enrichment  : In general the enrichment phase has moderate contribution to the various impact indicators and it is not adominant contributor to any impact indicator …If the whole nuclear lifecycle is considered, then enrichment has negligible contribution ( <1%) to the water pollution, land use, water withdrawal, eco-toxicity and human toxicity. It has some contribution to the SOx  3% and NOx emission 4%, water consumption, 2% , technological waste 2%, acidification potential 4%, It has larger than 210% cotribition only to the total GHG emission GNH relase  12%) and the eutrophication potential 18%).

Reprocessing of spent nuclear fuel : Commercial scale reprocessing of spent nuclear fuel for civil purposes is now a mature technology that has been practised for several decades….. In the light of the above analysis it can be concluded that industrial activities associated with reprocessing of spent nuclear fuel do not represent significant harm to human health or to the environment. They do not represent significant harm to any of the TEG objectives, provided that the associated industrial activities satisfy appropriate Technical Screening Criteria

Operation of power plants : Provided that nuclear power plants are built, operated and decommissioned within the limits set by existing regulations, they do not pose a significant harm to any of the TEG objectives. In the light of the above analysis it can be concluded that NPP operation activities do not represent unavertable harm to human health or to the environment. They do not represent significant harm to any of the TEG objectives, provided that the associated industrial activities satisfy appropriate Technical Screening Criteria.

Final repository : No radiologically relevant release or impact to the public is expected during the construction and the operation of the final repository.

Declaration of intention :

 The ECR Group: “If the EU and its global partners really want to tackle issues such as climate change, recycling, waste, emissions and pollution, food quality and food security, then the EU needs to adopt sensible and sustainable measures which do not place unnecessary and costly burdens on businesses and Member States. Rather than unrealistic targets which will never be fulfilled or properly implemented, the ECR Group supports an ambitious, incremental, and sensible approach that all Member States can support

Renew Europe: “We will invest in a sustainable continent. We do not have a Planet B, so we must make sure that we preserve the one we have for future generations. The Paris climate agreement of 2015 set out the roadmap, now it is time to deliver on the promises made and even go beyond them.”

Purpose and peer review : Stick to  Evidence-Based Analysis: “Do the Numbers” The EU is committed to evidence-based policy-making, also in the areas of energy and climate policies

 “This report presents the results of a study that examines three issues that are key to the EU climate neutrality’s ambition: i. The effect of EU climate neutrality on the average global atmospheric temperature by 2050 and 2100; ii. The spatial (land and sea) requirements for wind and solar energy versus nuclear energy in the Czech Republic and The Netherlands; and iii. The cost of wind/solar energy and of nuclear energy for these two countries. Each of the key chapters has been reviewed by at least two peer reviewers with relevant academic qualifications and professional backgrounds. A list of these peer reviewers is attached to this.”

Holistic, Constructive and Innovative Approach : “There is a lack of integrated, holistic analysis useful to policy makers; specifically, the Summaries for Policy Makers (SPMs) prepared by the IPCC do not provide it, and are silent on such critical issues as spatial requirements and costs of power generation technologies. The issues addressed in this report lend themselves very well to an integrated assessment…Further, analysis and advice for policy makers is often colored by a selective or subjective perspective on the relevant issues. Further, much analysis and tools for policy makers incorporate value or normative judgments that remain hidden in the technical details….This applies also to tools, such as the Energy Transition Model (ETM). By generating nuclear variants on the scenarios for the Dutch government in the ETM, however, this study demonstrates that even in a model that is not designed to treat nuclear on equal footing with renewable energy, nuclear energy is not necessarily inferior to wind and solar

For instance, the team identified the limitations of the so-called ‘levelized cost of electricity’  (LCOE)methodology as applied to nuclear and renewable energy for purposes of policy-making. In addition, it has unraveled the complexities around the market-based weighted cost of capital or ‘WACC”

2) Main Results and Conclusion-Summary

This study analyses and compares two climate neutral power-generating technologies that can result in decarbonization of the electricity system6 -- wind/ solar and nuclear. We assess the amount of space necessary for each technology to deliver the power required, and the costs of the power thus generated. This analysis has been done for two EU member states: The Netherlands, a country along the North Sea with abundant wind, and the Czech Republic, a landlocked country with no access to sea and less wind. This study also assesses the effectiveness of EU climate neutrality.

2a) Space requirement- Netherlands : We found that amount of space required to provide annually 3000 PJ (PetaJoules) of power in The Netherlands by wind and solar power in 2050 would range from 24,538 to 68,482 km2. To put this in perspective: 24,538 km2 is roughly the size of the five largest provinces of The Netherlands combined (Friesland,Gelderland, Noord-Brabant, Noord-Holland, and Overijssel); and 68,482 km2 corresponds to about 1.8 times the entire land territory of The Netherlands.

To generate the same amount of energy, nuclear power would require, on average, no more than 120 km2, which is less than half the size of the city of Rotterdam. Thus, due to their low power density, wind energy requires at least 266 (offshore) to 534 (onshore) times more land and space than nuclear. to generate an equal amount of electricity; for solar on land, at least 148 times more land is required (disregarding, in all cases, the additional land required for the necessary network expansion and energy storage or conversion solutions)

(NB :  1 Petajoule = 0.28 TW.h 3000 PJ =  840 TW.h . Electric Consumption in : 2018 : 117 TW.H. Hence,  2018 electric consumption by wind and solar would require 25% of Netherland territory – more details underneath)

Space requirement-Czech Republic : For the Czech Republic, the amount of space required to generate 1,800 PJ by wind and solar would range from 14,630 km2 to 43,758 km2. To put that into perspective, that covers 19 % and 55 % of the Czech Republic’s available land. Achieving the same level of electricity output with nuclear power would require no more than 269km2.

( NB Czech Republic : 1800 PJ= 504 TW.h Electric consumption in 2018 :  74 TW.h en 2018 would cover  15% of territory

Conclusion Space Requirement : While nuclear requires a tiny bit of land to provide a whole lot of power at a low cost, wind and solar require a whole lot of land to provide a tiny bit of power at a high cost.

2b) Cost Study

 The cost of nuclear is generally lower than the cost of wind/solar, in most scenarios by a significant margin. In the best-case scenario for wind/solar, the cost of nuclear is still slightly lower. In the worst-case scenario for wind/solar, nuclear cost only one fourth as much as wind/solar, i.e. wind/solar cost four times as much…In reality, the cost of wind/solar is even higher because these technologies require other expenses to bring the power where it is needed and to maintain the integrity of the electricity system (so-called integration- and system-related costs).

Importantly, as the rate of penetration of wind and solar power increases, the integration and system-related cost increase exponentially, further widening the gap between the low cost of nuclear power and the high cost of renewable power.

Based on ETM modelling for The Netherlands, we found additional integration cost for wind/solar at levels of up to 18 %, further deteriorating the economic case for wind/solar.

Furthermore on methodology : Loss of ENR value :  We note here too that our model does not discount renewable electricity produced when there is no demand for electricity. Economically, the stochastic nature of renewable electricity generation means that electricity may be produced when there is no demand for such electricity. Of course, such electricity does not have the same value as electricity produced when there is demand; to the contrary, it may even have a negative value. As said, in our model, the value of renewable electricity is not discounted to account for this problem.”

Comment : This is a well known phenomenon sometimes designated as “cannibalization” of Renewable energies and manifested by negative market prices when energy is generated when not needed. There are some recognized  ways of taking this into account, eg; VALCOE ( Value Adjusted LCOE) . This is well explained for example in the report(Possible role of nuclear in the dutch energy mix in the future_see https://www.laka.org/docu/boeken/pdf/1-01-0-20-23.pdf#page=2 and https://vivrelarecherche.blogspot.com/2020/11/role-possible-du-nucleaire-dans-le.html). It gives this ( this cannibalization effect increases sharply with the % of ENRs)

It gives this ( this cannibalization effect increases sharply with the % of ENRs)

System costs including VALCOE to add to classical LCOE estimations :


Other externalities : Many solar and wind turbine installation impose negative externalities on surrounding land. Frequently, other land usages become impossible because they would restrict the sun rays or wind flow. Other negative externalities of renewables that are not taken into account include the impact on surrounding nature and the impact on surrounding home values. A report commissioned by the Dutch government found that wind turbines built within 2 km of residential areas resulted in a 2% to 5% reduction in value of home prices, for example.  While this negative externality is not directly borne by the energy producers, households experience a decrease in their asset values, which in turn could negatively impact tax revenues (through, for example, reduced real estate taxes, wealth taxes, etc.). Nuclear power plants also impose negative externalities on the surrounding land, but given their much more limited footprint.

Comment : Estimations in France based on public notary and real estate agencies are more in 20-40% loss of value see eg https://vivrelarecherche.blogspot.com/2020/05/les-margoulins-de-leolien-et-leurs-gros.html

And the fact that ENR are certainly not cheaper than uclear, you can already see it :

Conclusion : A European Nuclear renaissance program :  

An unambiguous choice for the nuclear power option would meet the EU policy objectives of energy security, affordability, and social acceptability.  In light of the spatial and economic consequences of renewable energy relative to nuclear energy, the EU is well advised to consider a “Nuclear Renaissance” program. Under this program, the EU would create a level playing field for all electricity generation technologies…The authors hope that this study will be widely distributed and read. The people of Europe deserve it and the energy transition needs it. Brussels, December 2020.

3) Space requirements_detailed study :

If electricity in The Netherlands and the Czech Republic is solely or chiefly provided by wind turbines and solar panels, these renewable energy technologies will take up very significant portions of the available land. This is due to the low power density of wind and solar, which is approximately 150 to 500 times lower than the power density of nuclear power, on average.

Depending on variables such as electricity demand and capacity factors, in realistic scenarios, there is not enough land to meet all power demand if the Czech Republic and The Netherlands were to rely solely or predominantly on wind and solar power. In the Czech case, it is even out of the question that the available land will be sufficient to cover all electricity demand

In The Netherlands, offshore wind may alleviate the pressure on land somewhat, but creates its own issues in terms of marine impacts and costs

If electricity in The Netherlands and the Czech Republic is solely or chiefly provided by nuclear power, nuclear power plants will take up only a minute fraction of the land and space necessary for wind and solar. This is due to the very high power density of nuclear, which is at least 150 up to over 500 times higher than the power density of wind and solar.

Nuclear power plants can be sited at the same sites where fossil fuel-fired power plants are located, and require approximately the same area as such plants, which implies savings on infrastructure to connect to the network. These features greatly reduce pressures on land availability, landscape protection and nature protection, which is a significant advantage, in particular when competition for land increases..

Compared to wind and solar, nuclear power produces approx. 500 and 150 times more electricity per square kilometer. These numbers exclude the additional land and space demand imposed by renewable energy, which increases exponentially as renewable energy expands and makes up a larger share of the power mix. This additional land is required for additional infrastructure necessary for the integration of renewable energy into the electricity system, such as energy storage and conversion facilities.

3a) Scenario Netherlands

3 scenari have been studied :

2019 Baseline” – This resembles the current (2019) make-up of energy demand and electricity mix: 3,000 PJ of annual energy demand, with 15% being met by electricity. In other words, every combination of nuclear and renewables supplies 450 PJ of energy per annum

“2050 H/H” – This represents an extreme scenario that projects 4,000 PJ per annum and a 50% rate of electrification (high/high). Renewable and nuclear power jointly supply 2,000 PJ per annum

“2050 Berenschot” – This resembles Berenschot’s “Regionale sturing” scenario from the CNS Study,with energy demand dropping to 1,750 PJ per annum and 45% of that being met with electricity.In other words, every combination of nuclear and renewables supplies roughly 790 PJ per annum


Main results :

At a low level of power demand (Bereschot), 100% renewable power imposes serious requirements on land and sea space, at 34% and 39%, respectively; these ratios may exceed the amount of space policy makers are willing to allocate to power generation.

In the 2050 H/H scenario, the limits of available space are reached or exceeded. At 100% renewables, 98% of the available sea is utilized and 86% of the available land.

In the 2019 Baseline scenario, 368 of the roughly 3,000 PJ in total energy demand, about 232 PJ came from renewables, just below 8%. This suggests that if policies were to move towards 100% renewables, we would need to increase the area currently covered by renewable energy sources by a factor of 12, both on sea and on land (then coming close to 80% available land/sea space)

A  perfectly equal power mix implies that the space demand of onshore water and roof space could exceed the available space. Thus, this mix might not be feasible.

Additional remark : In the case of offshore wind, the seabed space necessary for cabling may not be included; in the case of solar and wind on land, the underground space demand for cabling is typically ignored. In the UK, this additional space demand has been shown to be substantial; for three offshore wind farms up to 66% of additional seabed space is needed for the cable corridors. There is no reason as to why this would be any different in The Netherlands

3b) Scenario Czech Republic

Energy demand was roughly 1,800 PJ in 2018 and is expected by the government to decline to around 1,000 PJ in 2050, with electrification rates of 20 and 27%, respectively. For our sensitivity analysis, we model energy demand between 1,000 and 3,000 PJ and electrification rates of 10% to 100%.

3 Scenarios have been considered

2019 Baseline” – This resembles the current (2019) make-up of energy demand and electricity mix: 1,800 PJ of annual energy demand, with 20% being met by electricity. In other words, every combination of nuclear and renewables supplies 360 PJ of energy per annum

“2030 Target” – This represents the Czech Republic’s official target for 2030 that projects 1,600 PJ per annum and a 25% rate of electrification. Renewable and nuclear power jointly supply 400 PJ per annum.

“Conservative Scenario– This represents a more conservative scenario in which energy demand increases to 2,000 PJ per annum as does the electrification to 30%. Renewable and nuclear power jointly supply 600 PJ per annum.

 At the extremes, it shows that 100% renewable power requires more than the available space and, as such, is not a realistic scenario for the Czech Republic.

 The 2019 Baseline scenario begins to show what increasing shares of renewable power will mean for space utilization. Even at constant levels of demand, relatively modest levels of renewable energy impose serious requirements on land space (50% mix would occupy 50% of available land) 

e.g; The expected electricity production if we use 100% of the available space for renewable would be about 670 PJ per annum. For context, the Czech Republic’s primary energy demand for 2019 was just over 1,800 PJ, and hence renewable would generate no more than 40% of its energy demand

 In the 2030 Target scenario, the limits of available space are reached or exceeded even earlier. At 90% renewables, there is not enough land available.

In the Conservative scenario, the pressure on land usage becomes clearer. Hence, if there is some modest growth in energy demand and electrification increases, renewables would occupy all the available space at just over 50% of the energy mix.


The model output confirms that the spatial requirements of wind/solar are such that these technologies cannot be the main sources of power in the Czech Republic. While wind/solar would use up all available space quickly and still provide power output that may be insufficient to meet the demand, nuclear power would have much smaller spatial impacts and provide much more power. Indeed, the results of our modelling demonstrate also that the Czech government’s plans for the electricity sector, with a modest role for wind/solar and a significant role for nuclear power, are sensible from a spatial perspective.

The Czech NECP, however, warns that the renewable target may appear to be unachievable without continued subsidies and that the high share of renewable energy contemplated in 2030 may cause blackouts

4) Cost studies- detailed

Conclusion : In virtually all realistic scenarios, nuclear power is cheaper than wind and solar power in terms of € per MWh in both the Czech Republic and The Netherlands, both at market-based interest rates and at a zero interest rate

Additional remarks :

1) Other costs : those figures only consider the costs of generating the electricity (LCOE) and not  the costs of transmission, distribution, storage and conversion (integration and system-related cost). The integration- and system-related cost of nuclear energy is much lower than that of intermittent renewable energy, which, moreover, increases exponentially as the penetration rate of renewable increases.

2) Warning about WAAC (weighted average cost of capital) :  the main drivers of the LCOE for both wind/solar and nuclear are, in order of importance 1)  (WACC), 2) capacity factor 3) capital costs, 4) fixed O&M cost

The WACC is the most influential, but also the most controversial factor. Based on thorough analysis of this debate, our approach estimates the WACC for policy makers by separating government risk(which policy makers control) from project risk (which operators control to a great extent). In standard LCOE calculations, non-intermittent nuclear electricity is discounted more heavily than intermittent renewable

In part because the WACC is also used as discount rate, the WACC to be applied in planning decisions is not a given for policy makers. The choice of a WACC/discount rate is a value-laden decision, not a technical matter to be decided by experts. Deciding the appropriate discount rate for policy purposes involves political and moral debates as much as economic and technical issues. Given that policy making can influence WACCs directly, policy makers should scrutinize the WACCs used in any LCOE.

Using a policy-neutral WACC of 3 % for The Netherlands and 4.2 % for the Czech Republic, we find that in most plausible scenarios nuclear power is cheaper than all types of renewable energy (offshore wind, onshore wind, solar) or any combinations thereof in both the Czech Republic and The Netherlands. Only if all or most variables turn out to be in favor of renewable and to the detriment of nuclear, some renewable power might have a lower LCOE, although not necessarily a lower total cost.

 Note that this cost comparison is based merely on LCOE and, thus, does not take into account integration and system-related costs, which are much higher for renewable power than for nuclear (see further below).

 In most plausible scenarios nuclear power is cheaper than all types of renewable energy (offshore wind, onshore wind, solar) in both the Czech Republic and The Netherlands, even before integration- and system-related cost is added, which is much higher for renewables.

Based on modelling with the ETM, for The Netherlands, total energy system costs could be reduced by as much as 18% by replacing renewable generation with nuclear generation, with more cost savings for those scenarios that initially had more renewables in the energy mix. Importantly, grid connection costs, only one part of the integration costs, were reduced by over 60 % in one scenario, which would save the Dutch government almost EUR 10 billion per year.

We further adapted the LCOE method by developing a synchronized lifetime analysis as an additional point of reference. A synchronized lifetime analysis is the preferred method for comparing various power generating technologies, because it avoids the distorting effects of discounting projects with different lifetimes and different production schedules. This method confirms that nuclear power is a more cost-efficient solution to meet chosen levels of electricity production over a given period of time, even before integration- and system-related costs are added.



Importantly, as the rate of penetration of wind and solar power increases, the integration and system-related cost increase exponentially, further widening the gap between the low cost of nuclear power and the high cost of renewable power.

3) Most of  the existing  scenarios treat both energy demand and energy production as an endogenous variable; each has their own, specific level of energy. As discussed in Part 5 of this report, we have decided not to do so, and treat power demand as an exogenous variable. This decision is based on the fact that the 2050 power demand is highly uncertain and depends on unknown variables, such as further energy efficiency gains that may be realized, the level of power usage by citizens in 2050, the level of power-intensive industries, innovations that may affect power demand (upwards or downwards), the general level of wealth….

5) Policy Recommendations

Because current EU policies favour renewable energy over nuclear energy, assessment of the relative cost of both technologies can easily be led astray.. This had the effect of reducing the price of renewable energy, but it has also had a relative inflating effect on the cost of nuclear power and of the deployment thereof in the EU.

Under the current EU and member state policies, the following benefits are extended to renewable energy, which are not (or only to a much more limited extent) available to nuclear power:  follow list of more than 15 financing device favorizing  renewables, including :  direct subsidies (grants) for research and development, Direct subsidies (investments grants, loan guarantees, soft loans) for actual renewable power projects, Mandatory, guaranteed minimum shares for renewable energy, Priority and privileged access to the energy market.. Quota obligations with tradable green certificates, Tax incentives, Tendering schemes that favor renewable power generators over other decarbonized power generators; Expedient permitting and regulatory procedures, Lack of obligation for renewable power generators to compensate property owners that suffer damage, No internalization of negative externalities (e.g.adverse environmental impacts) into the price of renewable power generation; Free riding on other technologies that keep the power system stable and flexible, such as base load generators and flexibility providers .

Comment : do not also forget the ery French ARENH, which requires EDR to finance its competitors by giving them access to nuclear powet at low price and when they want.

To meet the public demand for nuclear power, the EU should place renewable and nuclear on equal footing and endorse a ‘Nuclear Renaissance’ program. This program would comprise twelve key elements:

Equal treatment: All decarbonized power generation technologies (wind, solar, nuclear)receive equal treatment by the EU and member state governments

Generator pays principle: Based on the principles of cost internalization and “polluter pays,” all EU policies ensure that the fully loaded costs, including integration- and system-related costs as well as relevant externalities, are taken into account in policy making with respect to both renewable and nuclear power.

No discriminatory subsidies: All open and hidden subsidies, direct and indirect, in cash or in kind, and other advantages for renewable^energy (e.g. targets, priority rules, higher or guaranteed feed-in tariffs, subsidized infrastructure necessary for wind on sea, deflated land use prices, etc.) are eliminated, so that nuclear can compete on a level playing field.Other EU policies are not skewed to providebenefits to renewable energy.

Total system cost rules: The electricity market is redesigned so that total system costs, rather than marginal cost of subsidized power generation technology, drives carbon-neutral investments.

Differentiated electricity products: Based on the idea that unequal cases are not treated the same way, the concept of ‘energy only’ is no longer construed in a way that favors the marginal cost of stochastic, demand unresponsive electricity generation, but recognizes the fundamentally different nature of constant, on demand electricity supply, and demand-unresponsive electricity supply.

Holistic assessment: The extent to which power generation technology, whether wind, solar, or nuclear, has favorable or adverse effects on other EU interests and policies (such as habitat and species protection, toxic-free environment, agricultural policy, energy policy, etc.) and causes other externalities, is identified and objectively assessed in connection with policy making at EU and member state levels.

Expedient regulatory procedures: Like renewable energy, nuclear power equally benefits from expedited, efficient permitting and regulatory procedures

Legal and policy certainty: To encourage investment in the best power generation technology and keep the finance cost down, legal and policy certainty is guaranteed to both renewable and nuclear power.

Adequate compensation of damage:

Access to finance on the merits: Access to private and public finance is a function of the merits of power generation technologies. Privileges and discrimination in this area are eliminated.

EU nuclear energy regulation for the new era: EU nuclear energy regulations are reviewed and updated, as necessary, to ensure that they are fit for purpose and for the new era in power generation. Nuclear regulation is effective and efficient.

The EU’s 2050 climate neutrality strategy involves a high risk of policy failure. The anticipated energy transition, however, can hedge against this risk by deploying ‘no regrets’ solutions that are good investments, bring down emissions, and have little adverse impact. Nuclear power is such a solution

We have a problem we should take seriously :


We are not on the right track :



Externalization is not part of the game , nor of the solution !

Do not forget  : It is a whole world problem !

“EU climate neutrality, even if achieved, may have very little effect on the average global temperature increase. Other, non-EU nations have no obligation to reduce their emissions, and the EU has no way to force them to do so. Developing nations have a right to develop their economies. Thus, the EU’s efforts run a substantial risk of not achieving their objective….– If the EU is serious, it should purchase all world reserves of fossil fuels and retire them indefinitely. At current market price levels, the total cost will be at least €109,000,000,000,000, which is approximately 7 times the entire EU’s annual GDP and equals €560,000 per EU household.

Comment :More realistically,  this could be use as a  plead to compensate for very high price, technically difficult actions in Europe by subsidizing much more technically and cost efficient actions in other countries, eg replacing obligation of very high level isolation of old building by financing electrification of Africa.
