The group will extend the shutdown of five nuclear reactors for several weeks

Four French nuclear reactors, affected by corrosion problems, will see their shutdown extended for several weeks this fall, EDF said on Thursday, in a national context of very high tensions in terms of electricity supply.

The group maintains its nuclear production forecast for 2022 between 280 and 300 terawatt hours (TWh), even if this production could “probably” reach the lower end of this range, according to a spokesperson.

Four reactors concerned

This extension is linked to “a better estimate” of the time needed to carry out the investigations and repair work, he adds.

Between planned maintenance operations and shutdowns related to this subject of corrosion, 32 nuclear reactors were shut down on Thursday, out of a total of 56.

The four reactors concerned are: Cattenom 1 (return to the network now scheduled for November 1), Cattenom 3 (December 11), Cattenom 4 (November 14), and Penly 1 (January 23, 2023).
