LLFP transmutation in various fast reactors using a moderating target

Oki, Shigeo ; not registered

Transmutation property of long-1ived fission product (LLFP) was analyzed for various fast reactor cores having different fuel and coolant types. The inves tigated fast reactor cores were (1)sodium cooled and oxide fueled core, (2)sodium cooled and nitride fueled core (He-bond), (3)sodium cooled and nitride fueled core (Na-bond), (4)sodium cooled and metal fueled core, (5)lead cooled and nitride fueled core (BREST-300), (6)lead cooled and oxide fueled core, and (7)carbon dioxide gas cooled and oxide fueled core (ETGBR). Selected seven LLFPs were $$^{79}$$Se, $$^{93}$$Zr, $$^{99}$$Tc, $$^{107}$$Pd, $$^{126}$$Sn, $$^{129}$$I and $$^{135}$$Cs. Taking them into moderating target subassemblies loaded on the radial blanket region, the transmutation amount and rate of LLFPs for each investigated core were evaluated and compared. Followings are the main results: (1)LLFP transmutation property in a moderating target has little dependence on the fuel and coolant types of the fast reactor core. (2)A middle-sized core has larger LLFP transmutation amount per reactor power than a large-sized core.
