of the actinides in the MOX fuel as well as neutrons created via (α,n) reactions using representative advanced MOX fuel compositions, spent fuel, and other
The uranium isotopic composition is shown in Table 3. Due to the irradiation of the MOX fuel alongside UO2 fuel assemblies, the MOX fuel design adopts an enrichment pinmap to counter power peaking in the outer MOX pins adjacent to the UO2 fuel. The MOX fuel assembly geometry Advanced fuel fabrication facility (AFFF) has manufactured UO 2 based MOX fuel with a wide range of composition of PuO 2 for thermal and fast reactors. At present, AFFF is manufacturing PuO 2 based MOX fuel with composition of (U-21%Pu) O 2, and (Pu-28%Pu) O 2 for upcoming PFBR at Kalpakkam.
2017-06-20 MOX fuel. Details of the determination of the case burnups listed in Table 1 are given in Appendix A. A basic description of the SCALE/SAS2H depletion computation is given in Appendix B. The fuel assembly design and fuel compositions for the four San Onofre MOX assemblies are presented in this section. the influence of irradiation conditions and of the MOX fuel initial composition on the irradiated MOX fuel reactivity. Criticality calculations are also performed for PWR MOX fuel industrial applications in order to get Burnup Credit gain estimations. * Corresponding author, ludyvine.jutier@irsn.fr Tel: +33 1 58 35 94 45; Fax: +33 1 46 57 29 98.
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. Gamma autoradiography was used to monitor the composition, detection of wrong loading of MOX fuel pellets are made from a mixture of uranium and plutonium oxide.

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

The MOX fuel contains between 3 and 5% PuOz blended with natural or depleted uranium (in the proportion of 95-97%).

25 2001-12-01 the introduction of MOX fuel causes the number of glass units per GWd to double owing to the increase in the heat generation rate. An extended cooling period of the spent fuel prior to reprocessing effectively reduces the heat generation rate for UO 2 fuel, while a separation of minor actinides (Np, Am, and Cm) The composition of plutonium in the MOX fuel is the same with the one in PWR, but the weight percent is higher, up to 22.05%. There are two options in developing a fast reactor, one is called the breeder reactor, and the other is called the burner reactor. 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. Fuel type BWR60G-U02 BWR33G-MOX BWR45G-MOX BWR60G-MOX 1.05 1.03 1.02 1.01 Initial composition data for above BWR fuels deter MOX fuel pellets are made from a mixture of uranium and plutonium oxide.
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 cost savings claimed by Duke, if realized, would in fact be hundreds of millions of dollars in government subsidies built into the MOX contract, paid for by federal taxes.
