FUEL ASSEMBLY OF WATER-MODERATED WATER-COOLED POWER REACTOR Russian patent published in 2005 - IPC

Abstract RU 2255384 C2

FIELD: nuclear power engineering; nuclear-reactor fuel assemblies.

SUBSTANCE: each spacer grid of fuel assemblies has shaped supporting ribs symmetrically rounded-off on its edges abutting against corners of spacer-grid rims. Such design makes it possible to reduce nonuniformity of heat transfer in reactor core, to decrease resisting forces during emergency insertion of control rods, and to space apart fuel assemblies in core.

EFFECT: enhanced operating reliability and safety of nuclear reactor.
