our reactors well left to have to work ten more years

Extending the reactors designed to last for ten years to initially last forty years is the option favored by France for the moment. While waiting to go much further.

© EDF – The first two reactors of the Flamanville site are affected by an extension. Backing up save Receive electricity alerts 80 years is the record operating time granted to certain nuclear reactors in the United States. We are not yet there in France, even if the operator EDF believes that this perspective is no longer taboo. However, it is for the moment “only” to extend them by ten years, so that they reach 50 years. After the case of 900 electric megawatts (MWE) reactors, France is now starting to look at that of the second generation, those of 1300 Mwe. There are 20 distributed over 8 plants throughout the country: Flamanville, Paluel, Penly, Cattenom, Nogent-sur-Seine, Belleville, Saint-Alban and Golfech. They left the ground between 1985 and 1992 and were designed as all the rest of the park to last 40 years. From 2026, they will gradually face their fourth tense visit. It is to anticipate this deadline that the High Committee for Transparency and Information on Nuclear Safety (HCTISN) took the initiative of a concertation on the pursuit of their operation. His record published this week will precede the decision of the Nuclear and Radiation Protection Authority (ASNR), expected throughout the entire EDF program. And there is nothing of the public inquiry and the final decision that will be taken for each reactor. But this assessment has the merit of bringing out the concerns of the general public and of informing us about the main security issues of this extension. The tank, a critical component of the 40th anniversary, will be on the same principle as the previous ten -year visits: controls and tests on generators, containment materials, the holding of systems in the event of earthquake or the risk of fire. There is also a hydraulic test of the primary circuit and a pressure test of the containment enclosure. However, some components are more critical than others such as the reactor tank. “” A tank is a component that is not replaceable, “admitted the deputy director of the Nuclear Production Division of EDF Régis Clément, during a presentation to the press. “On the other hand, we can make sure to protect it and add elements inside which will avoid exposing its steel to radiation and thus extend its lifespan”. EDF is confident in its ability to maintain them over 60 years in operation but must still demonstrate it. ” This is the whole subject of the Grandendage program initiated by EDF since 2014: gradually modernize existing power plants to extend their operating time. “We also permanently improve the security of each reactor, so that everyone tends to the level of the Flamanville EPR. And we do it with a park that continues to produce, which is unique in the world, ”said Régis Clément. Regarding the natural risks due to climate change such as heat waves, earthquakes or floods, EDF believes that they will be a little later problem. As the power plants could be extended beyond the fifty years. The public consultation has also brought questions about EDF’s industrial capacities to lead all the works on the front. And difficulties in grasping the stages of procedures, which overlap for each generation of reactors, and can be spread over almost twenty years … To avoid this real gas machine, the idea makes its way to change your method. France wants to maintain its reactors as long as possible “an examination that projects itself with a period of ten years is no longer sufficient”, confirmed Julien Collet, Deputy Director of Deputy Nuclear Safety Authority and (ASNR). Even if it means giving the French that the games are already made on the decision to extend them and that there is no point in consulting them. A situation regrets Jean-Claude Delalonde, the president of associations in the information sector and transparency in nuclear safety (ANCCLI), responsible for informing the general public about nuclear activities. “We do not question the criteria that would require a final stop of the reactors. One wonders how to continue. And that poses a real basic problem, “he noted. It must be said that President Emmanuel Macron had announced the color during his Belfort speech in February 2022. “I ask EDF to study the conditions of extension beyond 50 years, in connection with the nuclear security authority,” he said. French electricity is produced at two thirds by nuclear power and there is a real economic opportunity to make our reactors work as long as possible.
