[Machine Translation] The tanks of the two Taishan EPRs, sold by Areva to China, were forged in the same factory and at the same time as the tank of the Flamanville EPR. They could have the same lack of resistance. This is enough to feed an expensive dispute with China. Is the anomaly of carbon concentration discovered in the tank and the lid of the EPR of Flamanville only the tree that hides the forest? While the Nuclear Safety Authority (ASN) delivered its verdict on these defective steel parts on Thursday (June 28th) – mandatory thorough inspections every ten years for the tank bottom, replacement before 2024 for the lid – Are turning to the two EPRs that EDF builds in Taishan, China. At the meeting of the Permanent Group of Experts on Nuclear Pressure Equipment (GPESPN), “EDF confirmed that the lower and upper caps of the Chinese EPRs were forged at the same time as the Flamanville EPR tank in The same Areva du Creusot plant. At this meeting, the Chinese nuclear regulator [NNSA] and the Chinese general nuclear power corporation (CGNPC) were present at the back of the room, “reports Yannick Rousselet, Nuclear Campaigner at Greenpeace France, himself an observer at the meeting of the group of experts. When asked by Reporterre, Pierre-Franck Chevet, the president of the French Nuclear Safety Authority, confirmed this information at the press conference on Wednesday 28 June: “The documents of the Chinese EPRs are potentially concerned because they were forged according to The same process, at the Areva du Creusot plant. To what extent they are, we do not know. “The Radiation Protection and Nuclear Safety Institute (IRSN) would have been more categorical:” From the beginning, they closely followed our expertise and their results led to the same results as ours “, said a representative of the” ASN’s technical body at BFM Business. As a reminder, the tank of the Flamanville EPR had been forged according to a new protocol, which resulted in abnormally high carbon concentrations in certain areas of the room. Testing by Areva showed that steel was less resistant to these areas and that cracks could spread more easily.
