  • Audition Sur Les Conséquences De L'arrêt Du Programme ASTRID
    Paris, le 25 novembre 2020 Audition sur les conséquences de l’arrêt du programme ASTRID Audition de Madame Valérie Faudon, déléguée générale de la Société française d’énergie nucléaire (Sfen) par les parlementaires de l’Office parlementaire d'évaluation des choix scientifiques et technologiques (OPECST). Tout d’abord je souhaiterais vous remercier, au nom de la Sfen, de nous recevoir aujourd’hui. La Sfen est une société savante, qui rassemble les scientifiques et ingénieurs du nucléaire depuis 1973. Notre raison d’être est de « permettre aux esprits curieux de se faire de nouvelles idées sur le nucléaire » et notre nouvelle signature est « faire avancer le nucléaire ». La décision de l’arrêt du programme ASTRID et de la mise en place d’un nouveau programme structurant « Promouvoir une économie circulaire au sein de la filière » a été actée par la signature du Contrat stratégique de la filière nucléaire le 28 janvier 2019. Pour rappel, le Comité stratégique de la filière nucléaire (CSFN), qui a rédigé ce projet, a, comme tous les comités stratégiques de filière, une configuration tripartite : organisations syndicales – Etat – Industriels. Parmi ces derniers, on peut citer EDF, le CEA, et Orano. Il est important de rappeler qu’il y a eu consensus, au sein des industriels de la filière, sur cet accord. Au niveau de la Sfen, cette décision a d’abord été une déception pour beaucoup de nos adhérents, attachés à l’excellence de la recherche nucléaire française dans le domaine des réacteurs à neutrons rapides. L’avant-projet sommaire (APS) d’ASTRID a reçu en 2016 le grand prix Sfen, qui est la plus haute récompense française en matière de recherche scientifique sur le nucléaire.

  • French Nuclear Expertise
    HIGH-TECH INDUSTRIES FRENCH NUCLEAR EXPERTISE KEY INFO IN 10 POINTS A MAJOR INDUSTRY France has expertise in all stages of nuclear energy production, from fuel extraction to reprocessing. With 1 220,000 professionals at 2,500 companies (operators, large corporates, SMEs, mid-size companies, startups), nuclear power is one of France’s largest industrial sectors. (French nuclear energy association SFEN, 2018) #1 SOURCE OF ELECTRICITY France’s 58 nuclear reactors at 19 sites, with a capacity of nearly 63 GWe (SFEN), accounted for 71.6% of all energy generated 2 in 2017, ahead of hydraulic power (10.1%), gas (7.7%), wind (4.5%) and solar (1.7%). Thanks to nuclear power and renewable energy, France’s electricity grid is more than 89.7% low-carbon. (French grid operator RTE, 2018) HIGHLY SKILLED JOBS Two-thirds of the nuclear sector workforce are executives or ‘ETAMs’ (employees, technicians and supervisors), 3 with twice as many highly skilled jobs as the French industrial average. There are nearly 70 specialist nuclear training courses in France. (SFEN, 2018) ELECTRICITY EXPORTS Every year, France exports 10-15% of all electricity produced. In 2017, it provided the equivalent of 4 €2.45 billion in low-carbon electricity per year to its neighbors (French Customs Authorities). The nuclear industry exports €6 billion in goods and services every year, generating a trade surplus of around €5 billion. (SFEN,2018) GLOBALLY RECOGNIZED EXPERTISE With its EPR (capacity: 1,600 MWe) and ATMEA (1,000 MWe) 5 reactors, France is involved in building various power plants around the world, in countries including Finland, China, the United Kingdom, and Turkey, with India soon to join the list.

  • Research Reactors in France
    Part 2 Research reactors in France Chapter 5 Evolution of the French research reactor “fleet” 5.1. The diversity and complementarity of French research reactors In the IAEA’s Research Reactor Database (RRDB), 42 reactors in France are identified as being research reactors93 (including those no longer in operation, the Jules Horowitz reactor (JHR) which is under construction, and the research reactors at defence-related facilities94). General de Gaulle created the French Atomic Energy Commission (CEA95) by decree in 1945, giving it responsibility for directing and coordinating the development of appli- cations for the fission of the uranium atom nucleus. In this context, a team led by Lew Kowarski started up the first French research reactor in 1948, the ZOÉ atomic pile built at the CEA centre at Fontenay-aux-Roses (figure 5.1). The core of this reactor, consist- ing of uranium oxide-based fuel elements (1,950 kg) sitting in heavy water (5 tonnes) in an aluminium tank surrounded by a 90 cm-thick graphite wall, stood within a 1.5 metre- thick concrete containment wall designed to absorb the different types of ionizing radiation emitted by the nuclear reactions in the core. The ZOÉ reactor was used up to a power of 150 kW to study the behaviour of materials under irradiation, and at 93. This database gives the full list of French research reactors. See also the CEA publication entitled “Research Nuclear Reactors”, a Nuclear Energy Division monograph ‒ 2012, or the publication (in French) “Les réacteurs de recherche” by Francis Merchie, Encyclopédie de l’énergie, 2015.
