Title: Refueling seal arrangement for nuclear reactor vessel

Abstract

An arrangement for sealing a flange circumferentially extending from a nuclear reactor vessel to a spaced opposing ledge to form a floor for a cavity above the reactor vessel to be filled with liquid is described comprising: plate means being sized and shaped for positioning above the flange and ledge to span and space therebetween and support a body of liquid; flange seal means adaptable for positioning between the flange and the plate means; ledge seal means adaptable for positioning between the ledge and the plate means; and lock means mounted to the plate means and engageable with only the flange to releasably lock the plate means to the flange to prevent upward movement of the plate upon inflation of the flange seal means and the ledge seal means.
