Sealing device for a component vertically disposed within the primary vessel of a nuclear reactor
Patent
·
OSTI ID:6317274
The device is constituted by a seal-bearing ring disposed about the flange of the component and resting on the plate of the reactor, having a first set of annular seals ensuring sealing between the inner side surface of the sealbearing ring and the outer side surface of the flange of the component and a second set of annular seals ensuring sealing between the base surface of the seal-bearing ring and the plate of the primary vessel. The device also includes a means for applying a vertical force downwards on the seal bearing ring and a means of injecting an isolating gas between the flange of the component and the plate 1 of the primary vessel on which the component rests. The device is especially useful for sealed mounting of components within vessels of fast neutron nuclear reactors.
