【 摘 要 】

The COGEMA UP1 reprocessing plant commissioned at Marcoule, France in 1958 handled roughly 20,000 metric tons of fuel from gas-cooled and research reactors. The commercial reprocessing activities of the UP1 plant ended in December 1997. CODEM, a joint venture created by the former users of the UP1 plant, including the utility Electricite de France (EDF), the French Atomic Energy Commission (CEA) and COGEMA, was established to fund and supervise decommissioning of the plant. COGEMA was selected as the industrial operator of the decommissioning project, which is scheduled to span a period of about 40 years. COGEMA, with its CODEM partners, had made the decision to proceed to a 'Final Shutdown' of the plant within a few years after the end of commercial operation. Final shutdown is intended to remove remaining fissile matter and highly radioactive materials, as well as some equipment, from the plant to ease the plant monitoring requirements compared with those applied when the plant was in operation.
