MOX fuel tends to run hotter because of lower thermal conductivity, which may be an issue in some reactor designs. Fission gas release in MOX fuel assemblies may limit the maximum burn-up time of MOX fuel. About 30% of the plutonium originally loaded into MOX fuel is consumed by use in a thermal reactor.
