Electricite de France SA must review its program of reactor checks after finding yet another crack earlier this year, the country’s nuclear safety authority said.

It’s not clear how the review will affect nuclear output, which EDF expects to recover this year after plunging in 2022 amid multiple halts for repairs. The shutdowns, caused by stress corrosion cracks on cooling-system pipes, added pressure to Europe’s strained energy system as Russian gas supplies dwindled.
