. . . 25 PREDICTION OF SPENT MOX AND LEU FUEL COMPOSITION AND COMPARISON WITH MEASUREMENTS B. D. Murphy and R. T. Primm III Oak Ridge National Laboratory P.O. Box 2008, Oak Ridge, TN 37831-6370 murphybd@ornl.gov; primmrtIII@ornl.gov ABSTRACT This work examines the capabilities of simulation codes to predict the concentration of nuclides in Se hela listan på world-nuclear.org (BARC), Tarapur for non destructive evaluation of MOX fuel pins for various types of reactors. MOX fuel pins containing pellets of three different composition (0.9%, 1.55%and 3.25% of PuO 2) were irradiated in Boiling Water Reactors.

Some is fissioned but spent LWR MOX fuel contains 75 percent as much plutonium as fresh MOX fuel. Repeated recycle to further reduce the plutonium is not practical because the changing isotopic composition of the pluto - MOX Fuel Rod Behaviour in Fast Power Pulse Conditions (started); Benchmark on the VENUS Plutonium Recycling Experiments – Configuration 7 (started). This report describes the detailed results of the benchmark investigating the physics of a whole VVER-1000 reactor core using two-thirds low-enriched uranium (LEU) and one-third MOX fuel. 96% of the content of used fuel is recyclable Composition of light water fuel after unloading from the reactor The uranium and plutonium from that sorting can be used to make new fuel assemblies. The plutonium is combined with depleted uranium to make MOX, a mixture of plutonium and uranium oxides. The MOX is then mixed with low enriched uranium (LEU) oxide for use as fuel in light water reactors. Existing reactor designs limit the fuel composition to 1/3 MOX and 2/3 LEU. Currently once the MOX fuel is used in a reactor it is not reprocessed again.

The fissile isotopes (uranium-235, Plutonium-239 and 241) represent 4.3% of the total. Uranium-235 constitutes only 0.2%, since "depleted" uranium is used in the fabrication of MOX fuels. mox fuel fabrication .

We have 2001-12-01 · The MOX fuel contains between 3% and 5% PuO 2 blended with natural or depleted uranium dioxide (in the proportion of 95–97%). The PuO 2 replaces the enriched fraction of 235 U oxide in the regular UO 2 fuel. 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.
The plutonium is combined with depleted uranium to make MOX, a mixture of plutonium and uranium oxides. In its most common form, approximately 10% of MOX is plutonium. In the MOX fuel, the isotopic composition of fissile species changes during the irradiation, with an increase of heavier Pu isotopes. The part of fissions in 239 Pu, which is of PWR fuel. (2) L'.lkLRM(EOC) of MOX fuel is 2%L1k less than that of U02 fuel. So, initial composition data for other BWR fuel types can be determined such that k 00 (BUEoc)'s meet the following values.
