Effect of TRU fuel loading on core performance and plutonium production of FBR

Permana, S.; Suzuki, Mitsutoshi; Saito, Masaki

The effect of trans-uranium (TRU) fuel loading on the reactor core performance as well as the actinide and plutonium composition in the core and blanket regions has been analyzed based on the large FBR type. Isotopic plutonium composition of TRU fuel obtains less composition than that of MOX fuel except for $^{238}$ Pu composition which obtains relatively higher composition. The significantly increasing composition is shown by $^{238}$ Pu for TRU fuel in the core region as well as its increasing value in the blanket region for doping MA case. Excess reactivity can be reduced significantly and an additional breeding gain can be obtained by TRU fuel in comparison with MOX fuel. Doping MA in the blanket regions reduces the criticality for a small reduction value and it gives a reduction value of breeding ratio.
