FUEL ASSEMBLY OF NUCLEAR REACTOR Russian patent published in 2015 - IPC G21C3/00

Abstract RU 2542324 C1

FIELD: power industry.

SUBSTANCE: invention relates to elements of a fuel assembly (FA) of a VVER-440 nuclear reactor. A FA cover is connected to a shank by means of six special screws having a conical shape of a head from below. On edges of a mounting seat of an end part, in the middle part around each of the holes for attachment screws there are cavities, the surface of which coincides with the deformed shape of the cover surface at loading with radial forces along the outline of holes or is close to it. Cavities have a width that is smaller than that of the cover edge.

EFFECT: providing alignment of a cover and an end part assembly.
