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. Available open literature on thermophysical properties of both MOX and UO{sub 2} fuels has been reviewed, and the best set of thermal properties has been selected.
Approximately 95% of the MOX material is composed of UO 2 ; thus, the materials’ properties closely match those of UO 2 fuels. For example, at Japan's Fukushima Dai-Ichi plant, about 6 percent of the fuel in reactor #3 was MOX fuel, which contains about 200 kilograms of plutonium.

For example, at Japan's Fukushima Dai-Ichi plant, about 6 percent of the fuel in reactor #3 was MOX fuel, which contains about 200 kilograms of plutonium. This amount is a small enough that it likely made no significant difference in the amount of plutonium that escaped into the environment.

MOX fuel is an alternative to the low-enriched uranium fuel used in the light water reactors that predominate nuclear power generation. For example, a mixture of 7% plutonium and 93% natural uranium reacts similarly, although not identically, to LEU fuel. MOX usually consi Used MOX fuel has an increased proportion of even-number isotopes*, along with minor actinides. Hence most spent MOX fuel is stored pending the greater deployment of fast reactors. (The plutonium isotopic composition of used MOX fuel at 45 GWd/tU burnup is about 37% Pu-239, 32% Pu-240, 16% Pu-241, 12% Pu-242 and 4% Pu-238.) dense MOX fuel ..
One of the challenges that TVA faces is that the public perceptions of using plutonium as fuel needs some explaining. TVA starts by describing that MOX is a mix of uranium and plutonium. MOX has about 4-percent plutonium oxide (of which 94 percent is Pu-239) and the rest is depleted uranium oxide.

The MOX fuel is characterized in terms of plutonium isotopics as reactor-grade (RG) or WG. The WG material has a much higher percentage of fissile material (239Pu and 241Pu) compared to the RG material, thus allowing lower plutonium concentrations with WG material to achieve the same total energy extraction. The neutronic performance of the MOX fuel has been benchmarked to a wide range of operating and test data.
