PLANT FOR CUTTING OF SPENT FUEL ASSEMBLIES Russian patent published in 2020 - IPC G21C19/00

Abstract RU 2732279 C1

FIELD: physics.

SUBSTANCE: invention relates to radiochemical industry and is intended for use in industrial processing line of spent fuel assemblies (SFA) irradiated in nuclear reactors. Plant for cutting of spent fuel assemblies of nuclear reactors includes upper and lower crossarms, intermediate spacers between them, fixed and movable blades, clamp, hydraulic cylinders of knife and clamp. Housing of the movable knife is equipped with a knife insert, the cutting part of which is symmetrically stepped so that a common reverse wedge and a shelf are formed. Working part of clamp is equipped with two wedges arranged in series one after another in SFA supply direction, and two clamping planes in cutting zone.

EFFECT: invention provides reliable, high-quality cutting without formation of liquid radioactive wastes.
