Fuel trouble at Cattenom

30 May 2001

An unprecedented number of failed fuel assemblies at Cattenom 3 is causing concern for EdF and Framatome ANP, which produced the assemblies. Investigations revealed that at least 38 of the unit’s 193 fuel assemblies had at least one leaking rod, and the rods were broken or cracked. It has yet to be determined why so many fuel assemblies have been affected at once. The French nuclear safety authority (DSIN) said the reactor would not be permitted to refuel until the problem is resolved.
