发明名称 METHOD OF DISMANTLING A WORN STEAM GENERATOR IN A PRESSURIZED WATER NUCLEAR REACTOR
摘要 Method of dismantling a steam generator (10) comprising a primary portion (20, 24) connected to the primary circuit of the reactor, said primary portion including metal elements (15, 22, 26, 28) contaminated by contact, during operation, with a cooling fluid in the reactor core. According to the method, the inner surface metallurgical elements of the primary portion (20, 24) are decontaminated by circulating a hard acid decontaminating solution containing quadrivalent cerium flow in contact with said surface, the steam generator is cut into sections (at H1, H2 and H3) to separate the decontaminated metal elements (15, 22, 26, 28) from the rest of the steam generator, the decontaminated metal elements (15, 22, 26, 28) are remelted and processed to form new metal elements.
