Fast reactors can utilize a wide range of fuel types, a mixture of transuranic elements as fuel, and various chemical forms. Fast reactor fuel can be made from UO 2, MOX, single or mixed nitride ceramics, and metallic reactor fuel can be made from pellets, in a manufacturing process similar to that for LWR.

A fast-neutron reactor (FNR) or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons (carrying energies above MeV or greater, on average), as opposed to thermal neutrons used in thermal-neutron a reactor needs no neutron moderator, but requires fuel that is relatively rich in fissile material when compared to.

Classification of Reactors according to Neutron Flux Spectrum. From the physics point of view, the main differences among reactor types arise from differences in their neutron energy fact, the basic classification of nuclear reactors is based upon the average energy of the neutrons which cause the bulk of the fissions in the reactor this point of view nuclear reactors are.

Figure 3 shows a Monte-Carlo simulation, using the MCNP-4C code [5] of the neutron spectrum inside the irradiation chamber, at the point closest to the simulation uses a detailed three-dimensional model of the core validated with extensive measurements in the reactor core [6].A Watt-Cranberg distribution, as described by Equation (1), normalized to the value at 2 MeV, is also shown.

Three main approaches were followed and are described here: direct measurements of Bm2 by means of axial and radial reaction rate traverses ; -a differential method which,by progressive substitution, gives the difference in Bm compared to a reference medium; -a complementary method, using detailed analysis of balance through central reaction.
