Abstract
The device is constituted by a seal-bearing ring 21 disposed about the flange 2 of the component 5 and resting on the plate 1 of the reactor, having a first set of annular seals 26,27 ensuring sealing between the inner side surface of the seal-bearing ring 21 and the outer side surface of the flange 2 of the component 5 and a second set of annular seals 23,24 ensuring sealing between the base surface of the seal-bearing ring 21 and the plate 1 of the primary vessel. The device also includes a means 32-34 for applying a vertical force downwards on the seal bearing ring 21 and a means 16,18 of injecting an isolating gas between the flange 2 of the component 5 and the plate 1 of the primary vessel on which the component 5 rests. The device is especially useful for sealed mounting of components within vessels of fast neutron nuclear reactors.
