PARIS (Reuters) - France's EDF has detected for the second time in less than a week a flaw in some of its oldest nuclear power plants, with no impact on operations and safety, it said on Thursday.
EDF, which found premature wear in back-up diesel generators in 8 of its 19 nuclear power plants, said it had started repairs last week which can be done whilst reactors were in action.
The French Nuclear Safety Authority (ASN) ranked the incident at level 1 of the international nuclear event scale that goes from zero to 7 on seven reactors and at level 2 for 1 reactor.
