Abstract (en)
[origin: EP0877388A1] A removable hermetic closure is claimed for a multi-purpose, metallic, irradiated nuclear fuel assembly canister, which consists of an upright tubular body (1) having a welded bottom and an open top and which is to be entirely enclosed in a thick-walled metallic over-pack. The closure includes removable solid metal discs (13, 13') located entirely within the tubular body (1) and seating, directly or via a seating disc or ring (12), on an internal peripheral shoulder (11) near the upper end of the body. Each solid disc (13, 13') includes a peripheral sealing arrangement (14, 15, 14', 15'), cooperating with a vertical portion of the wall, and a clamp is located within the body above and acting on the solid discs (13, 13') to effect sealing.
