FILTER FOR NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2017 - IPC G21C3/30 B01D29/11

Abstract RU 2610716 C1

FIELD: nuclear engineering.

SUBSTANCE: invention relates to atomic power engineering, namely, to nuclear fuel assemblies (NFA) structural elements of VVER type nuclear reactors, namely, to debris-objects filters (DOF). DOF is made of several plate-like structured filtration elements with slots for coolant passage in form of stretched rectangles, inclined to NFA axis in one of two mutually perpendicular planes at certain angle, providing absence of filtering element gap in direction parallel to fuel assembly axis. At that, to increase filtration efficiency DOF can have several (2…3) plate-like structured filtration elements, located relative to adjacent ones mirrorlike relative to their contact plane.

EFFECT: increasing of any shape debris-objects retention efficiency compared to existing DOF.
