EDF stops Chinon 3 to 22 Feb after fire, unit 4 offline to Thurs

(Montel) French utility EDF has halted its Chinon 3 and 4 reactors (1.8 GW combined) in France on Saturday due to a fire in the non-nuclear part of the former, which was due to restart on 22 February, it said.

Chinon 4 should be back online on Thursday at 06:00 CET, the state-run utility added in a statement but warned Chinon 3 could see its shutdown extended.

The plant’s response teams were “preparing the maintenance work that would be needed”, EDF said, with the fire having been extinguished, though the incident had no impact on the population or environment.

The blaze at Chinon 3 occurred on Saturday around 02:40 CET in the main electrical transformer that supplies the reactor, the firm and the ASN nuclear safety authority said.

The reactor stopped automatically, and the fire was extinguished before the emergency services arrived, it added, while Chinon 4 was “preventively” stopped.

“The fire is out and under surveillance,” said ASN.

EDF was unavailable for comment when contacted by Montel.
