CEA research on...
The CEA is strongly committed to ensuring the highest levels of nuclear safety, whether as an operator of nuclear facilities or as a research organisation. The studies it leads in the field are not only backing by IRSN, but also French (EDF, Areva) and foreign nuclear operators. These studies fall within a long-term approach of continuous progress. It is worth distinguishing between R&D on current Generation II and III reactors, and research devoted to Generation IV reactors for which nuclear safety is a major priority.Though the Fukushima accident did not reveal the existence of any new phenomena that needed investigating, it did highlight a number of key priorities and the need to maintain R&D efforts over time by relying on the available experimental facilities.
The research programmes at the CEA cover two key areas:
These programmes rely on the simulation of the physical phenomena involved and on the comparison of these simulations with the experimental results obtained in CEA's facilities, e.g.: shaking tables on the Tamaris platform to study the behaviour of structures under earthquake conditions, Mistra to study hydrogen risks, Plinius to study concrete-corium interactions, and Verdon to study fission product releases.
Research in this field can be divided into three main topics, each corresponding to a successive phase of an accident scenario:
R&D at the CEA is exploited by both nuclear operators and IRSN in particular within the scope of regulatory safety reviews.
Research carried out at the CEA within the scope of the Generation IV international forum (GIF) is particularly focusing on sodium-cooled fast reactors (SFRs) via the Astrid integrated technology demonstrator.
Sodium-cooled fast reactors have a number of inherent safety advantages when it comes to reactor cooling: significant thermal inertia and diversified heat sinks (water, but also atmosphere and natural convection).
Astrid and Generation IV SFRs in general must comply with the highest level of safety requirements, in particular by taking into account feedback from the Fukushima stress tests. Several technology breakthroughs have been developed by the CEA teams: the development of a new reactor core concept with optimised safety features, the elimination of sodium interactions' possibilities with air or water (risk of chemical reactions) and the development of a corium core catcher.
Europe and China have combined their efforts to progress research into severe accidents in light-water reactors. Their work within the Alisa project is resulting in better understanding of potential core flooding and molten core cooling scenarios, inside and outside the vessel, as well as the behaviour of hydrogen according to reactor design.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
