摘要： An improved diaphragm for use with a gasket to prevent leakage of a pressurized fluid. The diaphragm has an internal groove which uses strong spring back and the pressure of the fluid to increase the gasket seating load, thereby providing a self-energizing seal which can accommodate changes in gasket load due to changes in fluid pressure. In one embodiment, a ring is shrink-fit or press-fit about the outer side edge of the diaphragm which improves strength and reduces the material cost.

摘要： Apparatus and method for loosening a stuck reactor pressure vessel stud. A nuclear reactor pressure vessel has a threaded blind bore therein receiving an upright threaded stud having a centrally disposed passage longitudinally therethrough. A pulsar pump is in communication with the passage for supplying a pulsating liquid into the passage and thence into the bore. As the fluid exits the passage, it will push against the bottom of the bore and exert an upwardly directed hydraulic force against the end of the stud for upwardly lifting the stud. A controller is connected to the pulsar pump for controllably operating the pulsar pump. As the hydraulic force of the pulsating fluid lifts the stud, the fluid will migrate between the threads of the stud and the bore for peening or removing any debris from therebetween and washing it upwardly between the stud and bore to a suction pump in communication with the bore. The suction pump suctions the debris-containing liquid from the bore. The apparatus includes a rotation tool connected to the stud for rotating the stud as the liquid is pulsed in order to enhance removal of the debris from the threads. Removal of the debris allows the stud to rotate with reduced resistance to rotation and with the normal amount of torque applied thereto.

摘要： A head for closing a nuclear reactor pressure vessel shell includes an arcuate dome having an integral head flange which includes a mating surface for sealingly mating with the shell upon assembly therewith. The head flange includes an internal passage extending therethrough with a first port being disposed on the head mating surface. A vent line includes a proximal end disposed in flow communication with the head internal passage, and a distal end disposed in flow communication with the inside of the dome for channeling a fluid therethrough. The vent line is fixedly joined to the dome and is carried therewith when the head is assembled to and disassembled from the shell.

摘要： A reactor vessel O-ring spring clip designed to hold the tubular O-ring in the groove of a reactor vessel head flange, especially during head lifting. The spring clip is designed such that the weight of the O-ring acts to increase the friction force between the spring clip and the, typically, threaded hole into which it is inserted. The end of the clip adapted to be inserted through a slot in the tubular O-ring for securement thereto has a circular member thereon which prevents the spring clip from becoming disengaged from the O-ring during head lifting.

摘要： An integrated head package for a nuclear reactor has a pressure vessel closure head with control rod drive mechanisms thereon enclosed in a shroud, and a plurality of vertical lift rods secured to the vessel head with a missile shield plate extrending between the lift rods and vertically slidably retained between spaced stop members adjacent the upper ends of the lift rods. A lift rig is secured to the missile shield plate, preferably through attachment to support blocks secured to the upper surface of the plate. Impact forces of a missile against the lower surface of the missile shield plate are transferred to a lifting force and are not transferred to the lifting rods, head lugs, closure studs and pressure vessel supports.
