EDF declined to comment.

Some 19 reactors out of the 58 EDF operate are currently out of service, representing 19,300 megawatts (MW), or 30.51 percent out of 63,260 MW of French installed nuclear capacity that is offline.

On Thursday, EDF pushed back the restart of five reactors, cut its 2016 nuclear power output target for the third time this year and lowered its 2016 EBITDA target for the second time this year to between 16-16.3 billion euros from 16.3-16.6 billion euros previously.

The original forecast was for 16.3-16.8 billion euros.
