Leakproof door seal for nuclear plant - with inflatable hose in lightweight frame inside hinged door plate

摘要

Pneumatically sealed door for joining a nuclear reactor vessel to a storage tank for spent fuel rods or the latter to a fuel transport container consists of a hinged door plate and an inner frame. An inflatable multicavity hose is located in the frame and conforms to the shape of a flange around the door opening against which it seals. Lightweight leakproof seal for access doors in nuclear plant facilitates the door operation and the maintenance or replacement of the seal elements.
