EDF plans to change decommissioning strategy for first-generation reactors

摘要

France's nuclear operator EDF wants to change its decommissioning approach for the country's six first-generation gas-cooled reactors -from wet dismantling to dry dismantling. The company told nuclear safety authority ASN (Autorite de Surete Nucleaire) that it will carry out the complete dismantling of one of the six reactors, at the St Laurent, Chinon and Bugey nuclear station sites, before beginning the disassembly of the other five. This will allow it to benefit from the combined experience. EDF said the dismantling of peripheral reactor equipment at the six units, which were all permanently shut down between 1973 and 1994, should be completed within 15 years. ASN had called for a review of EDF's plans for the six units and will now examine the revised strategy.
