Abstract (en)
[origin: WO2021152342A1] The invention concerns a thermal sleeve (60) for a control rod drive mechanism of a nuclear reactor pressure vessel (4). The thermal sleeve (60) comprises : - a tube (62) comprising an upper end (68) and a lower end, the tube (62) comprising also an outer surface (70) and an inner surface (72), the outer surface (70) and the inner surface (72) extending from the upper end (68) to the lower end; - a plurality of protrusions (64) disposed at the upper end (68) of the tube (62), each protrusion (64) extending radially outward the tube (62); and - a collar (66) protruding radially outward the outer surface (70) of the tube (62) and extending circumferentially all around the tube (62), away from the upper end (68).
