Abstract
An annular plate is mounted on and sealed to the spaced apart pressure vessel flange and vessel containment structure of a nuclear reactor to form a leak-proof bottom for a refueling canal for the reactor. The sealing arrangement for the plate establishes redundant seals to each of the flange and containment structure, the seals being pneumatically expandable to enhance the integrity thereof.
