233 is less for thorium case than fissile material of U-235 in MOX fuel case. breeding ratio and actinide production composition for several fuel cycle schemes

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.

MOX fuel is manufactured from plutonium recovered from used reactor fuel. MOX fuel also provides a means of burning weapons-grade plutonium (from military sources) to produce electricity. In every nuclear reactor there is both fission of isotopes such as uranium-235, and the formation of new, heavier isotopes due to neutron capture, primarily by U-238.

MOX fuel is the hardening of the neutron spectrum [2, 3]. In order to overcome the spectrum hardening effect from plutonium isotopes in MOX fuel and to be able to have a core fully loaded with MOX fuels, a minor modification from the conventional 16X16 PWR type fuel assembly was proposed [3]. It is characterized by an internal region of the fuel MOX fuel may end up costing Duke money, rather than generating fuel-cost savings. MOX is several times more expensive than conventional uranium fuel.

The analysis of the MOX samples in glove box has required complicated and highly skilled operations. Therefore, for quality control analysis of the MOX fuel in a fabrication plant, simple, rapid and accurate analysis methods are necessary.
