On Monday 27 September, the French Nuclear Phase out Network "Sortir du nucléaire" received internal EDF documents, showing that the design and manufacture of the vessel closure head for the EPR in Flamanville could lead to a Chernobyl-type accident. Worse still, according to a memo written by the Head of nuclear fuel from EDF in 2001 (1), a Chernobyl-type accident is possible on all French nuclear reactors. The EPR is also concerned. Several EDF documents show that the number of welds and the type of steel used in some parts of the reactor vessel at Flamanville EPR may cause leaks. EDF considers that the leaks may, in turn, degenerate into a Chernobyl-type accident. This type of steel and welds are part of the emergency shutdown system of the EPR and cover 89 points of entry into the reactor vessel. Read the full press release.
