METHOD FOR IDENTIFYING SPENT FUEL ASSEMBLY Russian patent published in 2005 - IPC

Abstract RU 2249265 C2

FIELD: identifying o spent fuel assemblies with no or lost identifying characteristics for their next storage and recovery.

SUBSTANCE: identifying element is made in the form of circular clip made of metal snap ring or of two metal semi-rings of which one bears identification code in the form of intervals between longitudinal through slits. Clip is put on fuel assembly directly under bracing bushing and clip-constituting semi-rings are locked in position relative to the latter without protruding beyond its outline. For the purpose use is made of mechanical device of robot-manipulator type. Identification code is read out by means of mechanical feeler gage and sensor that responds to feeler gage displacement as it engages slits. Identifying elements are installed under each bracing bushing.

EFFECT: ability of identifying fragments of spent fuel assembly broken into separate parts before recovery.
