A method of coating a nuclear fuel with a burnable poison wherein the surface of the nuclear fuel is cleaned, and a burnable poison layer is then sputtered thereon. Preferably, a relatively low sputtering deposition rate is selected that would heat the nuclear fuel surface to less than 200 DEG C and external heat is applied to heat the nuclear fuel surface to between 200 DEG C and 600 DEG C. To make the burnable poison layer less hygroscopic, an overcoat layer of a hydrophobic material is sputtered on the burnable poison layer. |
