Abstract
A nuclear reactor vessel has a nozzle plug in its cold leg and hot leg nozzles for isolating the reactor vessel from the balance of the reactor coolant loop. The nozzle plug is mechanically compression fitted with the nozzle without the need for hydraulic or pneumatic actuation. The plug has a primary seal ring compressed against the inner wall of the nozzle and a secondary seal ring compressed against the end wall of the nozzle for withstanding a pressure differential of about 34 feet of water.
