SUPPORTING GRID FOR NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2007 - IPC G21C3/34

Abstract RU 2308775 C1

FIELD: nuclear power engineering; fuel assembly supporting grids for nuclear power reactors.

SUBSTANCE: proposed nuclear-reactor fuel assembly supporting grid is made in the form of perforated plate with round and hexahedral in holes. Round holes are used to receive fuel element tips and hexahedral holes, to pass coolant, three sides of hexahedron being parallel to lines connecting centers of adjacent round holes and three other sides formed by arc of circumference concentric with round hole.

EFFECT: enhanced stiffness and strength of supporting grid, reduced coolant flow disturbance and fuel element vibration.
