Abstract
A method of forming a water resistant boundary on a fissile material for use in a water cooled nuclear reactor is described. The method comprises coating the fissile material, such as a pellet of USiand/or the grain boundaries, to a desired thickness with a suitable coating material, such as atomic layer deposition or a thermal spray process. The coating material may be any non-reactive material with a solubility at least as low as that of UO. Exemplary coating materials include ZrSiO, FeCrAl, Cr, Zr, Al—Cr, CrAl, ZrO, CeO, TiO, SiO, UO, ZrB, NaO—BO—SiO—AlOglass, AlO, CrO, carbon, and SiC, and combinations thereof. The water resistant layer may be overlayed with a burnable absorber layer, such as ZrBor BO—SiOglass.
