On 8 September 2008 during the fuel unloading operation on the Tricastin no. 2 reactor of the EDF nuclear power plant, two fuel assemblies remained stuck to the upper internal holding structures of the reactor vessel.
On the 21st of July 2008, ASN proposed to the Préfet of Vaucluse that restrictions on water use in the region of Tricastin imposed by the order of the Préfet of July 11 2008 could be lifted on condition that the SOCATRI licensee implements comprehensive provisions for the monitoring of surface and ground waters until the end of August 2008.
ASN was notified on 7th October 2008 by the Isère prefecture of a radiological protection incident that had occurred at Mafelec's Chimilin site relating to radiation emitted by lift buttons manufactured by the company.
On July 17 2008 at 5 pm, the Franco-Belgian fuel manufacturing plant (FBFC), group AREVA-NP, located in Romans-sur-Isere in the French Drôme département, informed ASN of the rupture of an underground pipe of uranium liquid discharges.
During the night of July 7 to 8 2008, an incident occurred at the site of the SOCATRI company. A tank of the Uranium-bearing Effluent Treatment Station (STEU) of the SOCATRI facility overflowed in its retention tank. This retention tank was not leakproof at that time and caused a pollution of the environment.
