London — An outage at the 3.6 GW Cruas nuclear plant in southeast France caused by an earthquake Monday has led operatorEDF to adjust its 2019 annual nuclear output goal lower by up to 6 TWh to a range of 384 TWh-388 TWh, the French generator said Thursday.
Cruas is not expected to return to service before the first half of December, EDF said.
EDF's transparency website showed the plant's four 915 MW reactors returning to service at 23:00 CET on the following days: December 2 (Cruas 2), December 9 (Cruas 4), December 16 (Cruas 3) and December 19 (Cruas 1).
This is the second nuclear output revision by EDF in recent weeks.
On October 25, the utility cut the assumption 5 TWh to 390 TWh, citing the shutdown of Flamanville 1 and greater modulations than planned.
French nuclear output in 2018 was 393.2 TWh, up 3.7% on the year.
"Following the earthquake in southern France on 11 November 2019, EDF is continuing to carry out checks on the reactors of Cruas power plant (Ardeche) with the objective to complete them within a week," it said.
The results would then be submitted to nuclear safety regulator ASN "and, as of today, EDF anticipates a gradual return to service for the reactors at Cruas plant during the first half of December," it said.
All 2019 financial targets for the EDF Group remained unchanged, it said.
