Abstract
A plug which is inserted into the nozzle of nuclear reactor steam line is provided with a set of inflatable primary seals which resemble a pair of tires. A locking ring which features pads which can be hydraulically driven radially outward into engagement with the nozzle wall, is located adjacent the tire-like inflatable seals. The latter are inflated by a spring loaded piston. A tool which inserts the plug into the nozzle is adapted to tract the piston against the bias of the preloading springs, until such time as the plug is inserted into position. After insertion the piston is released and the seals are inflated.
