(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

It describes the actions, conditions and procedures for meeting safety requirements and deals specifically with the handling, processing and storage of plutonium oxide, depleted, natural or reprocessed uranium oxide or mixed oxide manufactured from the above to be used as a feed material to form MOX fuel rods and assemblies for export and subsequent use in water reactors and fast breeder reactors.

MOX fuel, short for mixed-oxide fuel, is a mixture of uranium and plutonium oxide. Most reactors use uranium fuel. As uranium fuel burns, some of it is converted into plutonium, so all operating reactors have plutonium in their core. Safety implications differ depending on the amount of MOX fuel that is used.

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. 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 2012-11-01 · While the typical isotopic compositions (mostly including only the minor actinides and the major fission products) of MOX fuel is well known and described in the literature, it is difficult to find detailed data how the concentrations change for the isotopes which are important in the source term (noble gases, iodine, cesium) with respect to Pu composition and Pu content. The MOX fuel is being fabricated through powder metallurgical route involving cold compaction and sintering.Annular MOX fuel pellets of two compos itions i.e. 21% and 28% PuO 2 are 2.1 MOx fuel Compositions The initial MOx composition selected is representative of realistic MOx fuels irradiated in a mixed UO 2-MOx PWR core, alongside UO 2 fuel assemblies. This MOx fuel consists of a typical plutonium vector for material derived from reprocessing of thermal reactor UO 2 fuels. that need the appropriate thermophysical properties of the 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. In its most common form, approximately 10% of MOX is plutonium.

Uranium-235 constitutes only 0.2%, since "depleted" uranium is used in the fabrication of MOX fuels. 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. Uranium-235 constitutes only 0.2%, since "depleted" uranium is used in the fabrication of MOX fuels.
