DEBRIS ENTRAINMENT FILTER FOR NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2005 - IPC

Abstract RU 2264666 C2

FIELD: nuclear power engineering; fuel assemblies of water-cooled reactors.

SUBSTANCE: proposed debris entrainment filter is made in the form of plate with holes formed as V-shaped slots organizing adjacent rows, slot length obeying dependence L ≥ 5 S; slots may be disposed in row in mirror image or row may be formed by alternating slot branches of adjacent rows.

EFFECT: ability of entrapping most fine particles without increasing fuel assembly pressure drop.
