Nuclear: the Environmental Authority demands more information on Flamanville

The Environmental Authority is asking for a series of additional information on the Flamanville nuclear reactor project (Manche), and in particular that the experience feedback from the other EPRs be taken into account, in an opinion published on Thursday. This administrative authority, which issues advisory opinions, has formulated a set of remarks and requests concerning the EPR under construction at Flamanville, which is due to start at the end 2022 after numerous delays and additional costs.

The Environmental Authority “recommends, on the eve of the commissioning of the reactor, to summarize the deviations, incidents and accidents experienced by the EPR in connection with the nuclear safety during its construction phase and to explain the measures taken to respond to it, in particular with regard to the reactor vessel “, she writes in particular.

” She also recommends presenting feedback from the Olkiluoto (Finland) and Taishan (China) EPRs and to specify how the ‘EPR will take this into account, in the context of commissioning but also to anticipate the uncertainties linked to this new type of reactor “, she adds.

The Finnish EPR just started this week while the two copies of Taishan in China have been running from 2018 and 2019. In July, an incident led to the shutdown of one of these EPR reactors in Taishan.

The Environmental Authority is surprised that the file before it does not refer to these reactors, of the same type as the one under construction at Flamanville.

“There is still a lot of work to be done on this site before start-up operations, and the experience feedback from deviation from the Taishan 1 EPR must take place “, recently ruled Julien Collet, Deputy Director General of the Nuclear Safety Authority (ASN).

In his opinion of 38 pages, the Environmental Authority is asking for further details, considering in particular that the scope of the project’s impact study is too limited.
