Abstract
Device for the dismantlable fixing of a guide tube in a recess provided for this purpose in the end piece of a fuel assembly of a nuclear reactor, particularly of the water-cooled type, wherein the guide tube has an end fitting, whose ferrule-like end has an inner cylindrical profile slotted over its entire length into a certain number of flexible sectors which can be engaged in an annular recess, or on a bore having circular engagement threads on its surface, under the pressure of an internal cylindrical locking ring, means also being provided for braking the locking ring in axial translation with respect to the end piece and for remotely ensuring the dismantling of the ring.
