NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2008 - IPC G21C3/00

Abstract RU 2319233 C2

FIELD: nuclear power engineering; reactor core components, mainly those for water-moderated water-cooled reactors.

SUBSTANCE: proposed fuel assembly has top nozzle, bottom nozzle, guide channels providing their intercommunication, fuel element bundle assembled by spacer grids, and support members disposed at fuel assembly corners. Support members function to join groups of spacer grids together. As an alternative, each spacer grid is joined by means of three support members with adjacent top spacer grid in addition to extreme top and bottom ones and by means of three support members with adjacent bottom spacer grid. Novelty is that fuel assembly support members may have their bottom nozzles joined with closest spacer grid.

EFFECT: enhanced reliability of mechanical design and safety of nuclear reactor.
