PRODUCTION OF SPACER GRATE Russian patent published in 2014 - IPC G21C3/34

Abstract RU 2524172 C1

FIELD: power engineering.

SUBSTANCE: production of spacer grate of fuel assembly comprises making of elements with inner ledges, securing them between themselves and to shell and annealing. At final step, definite residual strains are created in grate elements which allow a gradual decrease in internal inscribed diameter of elements at operation of fuel assembly in nuclear reactor.

EFFECT: tighter contact with fuel element shells.
