Abstract: | In a thermal neutron reactor, multiple recycle of U-Pu fuel is not possible due to degradation of fissile content of Pu in
just one recycle. In the FBR closed fuel cycle, possibility of multi-recycle has been recognized. In the present study, Pu-239
equivalence approach is used to demonstrate the feasibility of achieving near constant input inventory of Pu and near stable
Pu isotopic composition after a few recycles of the same fuel of the prototype fast breeder reactor under construction at
Kalpakkam. After about five recycles, the cycle-to-cycle variation in the above parameters is below 1%.
