The ad is wrong. Four French nuclear reactors, affected by corrosion problems, will see their shutdown extended for several weeks this fall, EDF said Thursday, August 25, in a national context of very high tensions in terms of electricity supply.

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). This extension is related to “a better guess“the time needed to carry out the investigations and repair work, he adds. Between scheduled maintenance operations and shutdowns related to this subject of corrosion, 32 nuclear reactors were shut down on Thursday, out of a total of 56.

However, the group maintains its nuclear production forecast for 2022 between 280 and 300 terawatt hours, even if this production could reach “most likely“the bottom of this range, according to a spokesperson. The price of electricity in France has been rising steadily for several months, breaking all-time records: it reached 900 euros per megawatt hour on Thursday, for delivery next year, against less than 100 euros a year ago, and less than 50 euros ordinarily in previous years.
