EDF finds another flaw in reactors
EDF, which found premature wear in back-up diesel generators in 8 of its 19 nuclear power plants, said it had started repairs 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.
The flaw was detected in some of EDF's oldest plants: Blayais, Bugey, Chinon, Cruas, Dampierre, Gravelines and Saint-Laurent and Tricastin.
"The anomaly is caused by premature wear," EDF said in a statement. "It is of no consequence to the operation and safety of the facilities in question."
Each nuclear power unit has three back-up diesel generators.
EDF said it has detected a technical flaw in 34 of its 58 nuclear reactors that could have an impact on safety.

A tenth of all electricity is lost in the grid - superconducting cables can help
PARIS - For most of us, transmitting power is an invisible part of modern life. You flick the switch and the light goes on.
But the way we transport electricity is vital. For us to quit fossil fuels, we will need a better grid, connecting renewable energy in the regions with cities.
Electricity grids are big, complex systems. Building new high-voltage transmission lines often spurs backlash from communities worried about the visual impact of the towers. And our 20th century grid loses around 10% of the power generated as heat.
One solution? Use superconducting cables for key sections of the grid. A single…
