PROCESS LINE FOR MANUFACTURING FUEL ASSEMBLIES Russian patent published in 2004 - IPC

Abstract RU 2231835 C2

FIELD: nuclear power engineering, manufacture of fuel elements for nuclear reactor fuel assemblies.

SUBSTANCE: detection units with collimating γ-quanta channels equipped with photoelectric multipliers, spectrometers, and computer outputting data on enrichment parameters and detecting pellets having deviations from desired 235U enrichment and their location in pellet stack are installed between start-of-stack stop-cutter and end-of-stack hold-down cutter of vibratory charging device on top and sides throughout entire length of pellet stacks disposed on horizontal beds of table top. Collimating channels are relatively offset.

EFFECT: enhanced production quality of fuel elements.
