ABSTRACT:
A getter-lubricant coating system between the nuclear fuel and the fuel cladding minimizes the pellet-clad stress concentration and renders fission gases and impurities unreactive to the cladding. The getters are matched to the lubricant matrix such that they are homogeneously dispersed in the matrix and are physically and/or chemically bound in place. A preferred form of the getter is a graphite or boron nitride intercalate of the getter material.
