NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2005 - IPC

Abstract RU 2248050 C2

FIELD: nuclear power engineering; fuel assembly manufacture.

SUBSTANCE: proposed fuel assembly has hexahedral spacer grid with coolant passage holes made in the form of equilateral triangles with rounded-off angles symmetrically disposed relative to holes for bottom plugs of fuel elements or tubular channels in the amount of six ones around each of them, their rounded-off angles being directed toward them; it also has similarly designed round holes for coolant passage.

EFFECT: enhanced flow section of holes for coolant passage through bottom support grid at same desired stiffness; reduced labor consumption and metal input.
