ABSTRACT:
A method for coating a nuclear fuel pellet is provided in which a liquid sol is formed containing the makings of a rare earth metal oxide. The liquid sol is applied to the exterior surface of the nuclear fuel pellet and the pellet is baked to form a solid coated pellet. If desired, zirconium diboride may be dispersed within the rare earth metal oxide matrix. Preferably, the rare earth metal oxide is either erbium oxide or gadolinia.
