[en] This publication comments the content of a report issued by RTE and the IEA on the conditions for a technical feasibility of scenarios exhibiting a high penetration of renewable energies (ENR) in France. It indicates the four conditions to be met for a security of supply and for the integration of very high proportion of renewable energies into a large scale electricity system: stability of the electricity system, supply security, operational reserves, grid development. These four conditions and the associated technical feasibilities stated in the RTE-IAE report are then discussed. The authors finally discuss whether a 100 pc renewable energy objective is actually to be wished.
[en] After having evoked the context (commitments related to the Paris Agreement, ecological transition, objective of carbon neutrality, reduction of the dependence of industry on fossil energies, use of decarbonized inputs to produce heat, and necessary development and deployment of new processes and also new technologies for CO2 capture, storage and valorization); this contribution proposes a critical discussion of the exploitation of hydrogen combustion, of its strengths and weaknesses, of its scientific and technological locks. Then, it discusses the exploitation of the combustion of hydrogen-natural gas mixtures (Hythane): production, strengths and weaknesses, benefits of such a combustion (due to energy properties of natural gas, to energy storage and transport, to CO2 emission reduction). It addresses the case of ammoniac combustion: NH3 production, use as fuel or energy vector, scientific and technological locks.
[en] RTE is the mainspring in enhancing energy transition and developing renewable energy in France. To further knowledge on the subject, RTE publishes a detailed inventory of existing and projected wind and photovoltaic installations. This vast overview was achieved with the help of ENEDIS (ERDF), SER (Association of renewable energy industrialists), and ORE Agency (Power network operators). The outstanding facts of this 24. edition of the renewable electricity synthesis are: 50% of renewable energy production capacity are from solar or wind origin. Solar and wind parks power reached almost 28 GW by December 31, 2020. With more than 25.7 GW of installed power, hydroelectricity remains the first renewable energy source in France. The bio-energy power generation park exceeds now 2.1 GW. All sources included, the renewable energy sources have grown by 637 MW during the last quarter 2020, reaching 55.9 GW at December 31, 2020. Power distribution systems are continuously evolving in order to meet the 40% renewable electricity production goal by 2030.

[en] In this paper, translated from an article published by Nuclear Engineering International (NEI), the author presents his views on the future of civil nuclear propulsion: nuclear powered container ships have returned after a decade in the doldrums, nuclear energy already present at sea with more than 200 naval reactors, the development of Floating nuclear power plants, the question of docking of nuclear-powered ships, the possible resistance from incumbent interests at sea in future.
[en] The UAE was the first Newcomer country to start building a large nuclear power plant in three decades: The Nuclear Construction of four units of the Barakah Nuclear Power Plant started simultaneously in 2012 - Sets a role model globally by achieving in a record time requirements needed to ensure its nuclear infrastructure was capable to support the programme through the highest levels on nuclear safety, security and non proliferation; The FANR issued also regulations for onsite as well as offsite nuclear emergency preparedness and response, and the combined onsite and offsite arrangements were put in place. EPREV including the follow up done; The country builds its national capacity for a sustainable operation simultaneously. Simulators in FANR and at site. Online monitoring of plant parameters are available at FANR as well as laboratories and monitoring systems; Highly experienced regulatory experts support the program in headquarter in Abu Dhabi and at site office in Barakah. Steps taken by FANR - Initial phase: The creation of the necessary skills and legally binding requirements for the safe siting, construction and design of the reactors to be built as well as for the needed security and non-proliferation arrangements; Evaluation: FANR evaluated the project based on a two step process, first construction license and then the operating license. This included further innovative design enhancements to address extreme conditions related to severe phenomena inside and outside the reactors. Systematic documentation and knowledge management built at FANR; Enhancement: Environmental effects on the reactors, as well as additional cooling and power supply measures enhanced. UAE specific factors and Fukushima impact. Making the most of synergy: The government signed international agreements & conventions supporting the programme developments; The agreements with the country of origin regulatory bodies which allowed FANR to leverage the work of the Korean regulators to license the reference plant in Korea, the Shin Kori 3 and 4 reactors; Support of the IAEA was instrumental in ensuring that the FANR approach to regulation kept with the best international practices; A pool of international experienced experts work hand in hand with local staff to develop regulations, conduct assessments and do inspections. Also the competence based framework for training and mentoring is essential for sustainability of FANR as a recognized nuclear regulator worldwide; FANR has over 30 agreements with international organizations & other regulatory bodies to exchange technical knowledge & build national capacity.
[en] Illustrated by many maps, graphs and tables, this publication proposes a rather detailed overview of the status and development (production and location, employment, sector turnover, market and tariffs) of the different electricity-producing renewable energies: wind energy, photovoltaic energy, hydraulic energy, solid biomass, biogas, renewable urban wastes, geothermal energy, marine energies). This issue includes a chapter on the Regional plan for land use and sustainable development (sraddet), and a regional overview of the different electricity-producing renewable sectors. A focus is proposed for each French region.
[en] National nuclear institutes (NNIs) contribute significantly to national development, providing services focused on developing and applying relevant technologies for the public good. While many NNIs provide commercial services and products that generate revenue, some are financially dependent on subsidies from national governments. This publication presents the outcome of a workshop which addressed the challenges for Member States regarding self-reliance and sustainability of their NNIs. Participants discussed efforts and best practices to cope with these challenges. The publication includes positive examples of tools or measures to be used in practical projects and programmes for achieving management goals towards self-reliance and sustainability. Examples of governmental policies in support of self-reliance and sustainability of NNIs are also presented. Finally, the country presentations in this publication show some examples of how NNIs cooperate with public or private stakeholders, providing some insights on how partnership opportunities can be explored.
[en] After a discussion of the characterization of the security of supply (match between supply and demand on the long and medium terms), and having shown that the planned closure of steerable capacities in Europe should be better taken into account in order to guarantee the security of supply before 2030, this note comments the rate of development of intermittent renewable energies. It notices that these energies have a smaller guaranteed power, outlines that France, Germany and Belgium display the highest deficits of steerable power, that a high share of intermittent renewable energy within the energy mix increases the probability of grid destabilization, and increases the steering complexity, and that it is necessary to adapt grids and to develop demand flexibility. The authors outline that energy transition is poorly coordinated at the European level, which increases this weakening. Some recommendations are finally stated. An appendix presents the main hypotheses, uncertainties and observations related to this study.
