Coating a nuclear fuel with a burnable poison

Patent ·
OSTI ID:5666416
A method is described for coating a nuclear fuel with a burnable poison, comprising: (a) cleaning at least a section of the surface of the nuclear fuel; (b) choosing a burnable poison sputtering deposition rate that will heat the surface of the nuclear fuel to a generally steady-state temperature less than about 200/sup 0/C; (c) sputtering, at the chosen deposition rate, a layer of the burnable poison on at least a portion of the cleaned section of the nuclear fuel; and (d) applying heat, during sputtering, to the nuclear fuel to maintain its surface temperature between about 200/sup 0/C and about 600/sup 0/C.
