EDF wrote in a press release, «preventive maintenance checks on the primary circuit of reactor number 1 of the Civaux Nuclear Power Plant» found cracks due to corrosion on the pipes.
The French power giant said:
- Checks initiated on the same equipment of reactor number 2 of the Civaux Nuclear Power Plant revealed similar defects
EDF temporarily closed Civaux:
- to replace the affected parts on the 2 Civaux reactors, the work being governed by a technical instruction prepared in cooperation with the ASN, which leads to extend the shutdown of the 2 reactors
Both power plants use the same reactor technology.
The temporarily closing of Civaux's reactors and Chooz's reactors will reduce 1 terawatt-hour of output and couldn't come at the worst time as cooler weather sent French power contracts to a record high earlier this week.
