Investigations continue into possible stress corrosion in several of EDF’s nuclear reactors in France.

EDF has said it found indications of possible stress corrosion on the
auxiliary circuits of four French nuclear power reactors totalling 4.8 GW
in capacity, namely Chinon 3, Cattenom 3, Flamanville 2 and Golfech 1. The
signs of possible corrosion were detected during ultrasonic inspections of
parts of the piping at its Chinon 3 (905 MW), Cattenom 3 and Flamanville 2
(1.3 GW each) reactors, the French state-owned utility said in a statement
at the end of last week.

The units are among six reactors that EDF
considers as “priority” for these checks, with the other three being
Flamanville 1 (1.3 GW) and Bugey units 3 and 4 (880 MW each). Meanwhile,
inspections carried out on the safety injection system circuit at Golfech 1
(1.3 GW) during planned maintenance also detected indications of possible
corrosion, EDF added. A spokeswoman told Montel on Tuesday that the utility
was carrying out further investigations to find out whether it was
corrosion or not.
