Explaining MOX to the public. 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 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 .. Thermal conductivity of irradiated hypostoichiometric (x = 0.05) 95% dense MOX fuel .. Composition of MOX fuel Composition of MOX fuel for a ton of metal (uranium + plutonium). The fissile isotopes (uranium-235, Plutonium-239 and 241) represent 4.3% of the total.

Mox fuel density

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. engineering analysis. Moreover, certain modelling approaches of MOX fuel in-reactor behaviour, regarding densification, swelling, fission product gas release, helium release, fuel creep and grain growth, are evaluated and compared with the models for UO 2. In MOX fuel the presence of plutonium rich agglomerates adds to the complexity of fuel ity as a function of density, temperature, Np content, Am content, and O=M ratio.

MOX fuel is an alternative to low enriched uranium (LEU) fuel used in the light water reactors which predominate nuclear power generation. Some concern has been expressed that used MOX cores will introduce new disposal challenges, though MOX is itself a means to dispose of surplus plutonium by transmutation .

Depleted uranium is a byproduct of the uranium enrichment process. The mixed oxide (MOX) fuel is one of the most important fuels for the advanced reactors in the future. It is flexible to be applied either in the thermal reactor like pressurized water reactor (PWR) or in the fast reactor (FR). This paper compares the two approaches from the view of fuel cost. Two features are involved.

It was, furthermore, found that the complete cleanup of the powder MOX fuels usually consist of plutonium blended with natural uranium. For simplicity and for purposes of this example, it will be assumed, that the reactor core contains only MOX fuel (100% MOX) and that the averaged percentage of plutonium (averaged over all the used fuel assemblies – not all FAs are fresh FAs) in MOX fuel is equal to 4%.
