" for a start-up of the Flamanville (Manche) EPR at the end of 2022, given the weld repairs that must be carried out, the president of the Nuclear Safety Authority (ASN ), Bernard Doroszczuk.

If all goes well, these weld repairs on the various parts of the secondary circuit of the EPR reactor should be completed in early 2022,
" said Bernard Doroszczuk during a hearing in the Senate.
These repairs are on the critical path of the project with regard to EDF's objective of targeting commissioning by the end of 2022. There is no longer any margin,
" he said.
The welds affair led EDF to announce in 2019 a further delay of at least three years for the EPR, where the loading of nuclear fuel is now expected at the end of 2022. EDF must in total resume a hundred welds, for which problems were detected in 2018. For the eight most difficult, the group favored the use of remotely operated robots, a solution for which ASN has just given the green light.
EDF also recently reported to ASN a design deviation concerning three taps of the main primary circuit of the EPR reactor under construction.
The tapping corresponds to the part of a pipe which connects it to another or to a vessel.

A solution must be found to strengthen the piping, the tapping, or resume welding,
" said Bernard Doroszczuk.
We will take positions this summer at the latest
," he said.
We cannot say whether the repair, in view of the strategy which will be presented by EDF, will allow
to enter into the planning
", warned Bernard Doroszczuk.
