Material attractiveness of plutonium composition on doping minor actinide of large FBR

Permana, S.; Suzuki, Mitsutoshi; Kuno, Yusuke

Material attractiveness analysis on isotopic plutonium composition of fast breeder reactors (FBR) has been investigated based on figure of merit (FOM) formulas as key parameters as well as decay heat (DH) and spontaneous fission neutron (SFN) compositions. Increasing minor actinide (MA) doping gives the significant effect to increase Pu composition; however, it composition of Pu and Pu become less. DH and SFN compositions in the core regions similar to the composition of MOX-grade and its DH and SFN compositions of blanket regions are categorized as compositions of weapon grade. Material attractiveness based on FOM1 formula shows all isotopic plutonium compositions in the blanket regions as well as in the core regions are categorized as high attractive material.
