MACHINE FOR BUILDING FUEL ASSEMBLIES FROM FUEL ELEMENTS Russian patent published in 2005 - IPC

Abstract RU 2244355 C2

FIELD: machine-assembly equipment for producing nuclear reactor fuel assemblies.

SUBSTANCE: proposed machine has pneumatic cylinder rod provided with its motion limiter and contactless sensor at drifting mechanism on through slit of bottom end part of fuel element; cone angle of drift-rod is 30 deg. and annular drilling diameter in each hole of auxiliary spacer grid equals nominal flare of fuel element end part sections internally drifted inside each annular drilling within upper nominal-size tolerance D = H^k, where D is annular drilling diameter; H is nominal flare; k is upper nominal-size tolerance.

EFFECT: enhanced quality of fuel assembly.
