METHOD AND DEVICE FOR CLOSING IN A WATER-FILLED POOL A LOADED CASE WITH IRRADIATED NUCLEAR FUEL

摘要

The process comprises immersing a case (12) and container (10) assembly in a pool, filling the case with nuclear fuel (4) and fitting a cover (D) with a case end plug over the assembly. The pneumatic fluid pressure inside the cover is maintained to hold the water below the level of the container's open end (30) while the open end of the case is closed and sealed using remote-controlled arms (16, 16'), with the seal verified before removing the cover.
