Abstract

A nozzle between the nuclear steam generator and nuclear reactor vessel has a dam, plug, or barrier mounted on the tapering internal wall of the conduit. A seating ring is mounted on the tapered internal surface of the nozzle through screws which will ensure release of the ring after pressure on the dam is removed, and the screws are backed away from engagement with the tapered surface.
