PROCESS AND DEVICE FOR DISASSEMBLING INTERNAL APPARATUSES OF A WATER-COOLED NUCLEAR REACTOR

摘要

The disassembly and/or the cutting up of each of the components (6) of the internal equipment fastened in the vessel (4) is carried out under water, inside the reactor vessel (4). Metal components (12) separated from the vessel (4) are obtained and are withdrawn successively from the vessel and then compacted under water in a compacting press. The metal components (36) obtained after compacting are deposited under water in a storage and transport container (37). The dismantling device comprises in particular a handling and cutting unit (11) which makes it possible to perform the cutting up of cylindrical sections of the reactor core enclosure (6) and the transporting of the sections (12) into the compacting press (34). …IMAGE…
