Recycle transmutation to reduce minor actinide for geologic disposal by using high flux LWR

Geologic disposal scenario combined with P and T (partitioning and transmutation) treatment has an inherent merit to avoid the unanticipated uncertainty which might take place in a super-long period existing in geologic disposal. A part of this study has a significant role to realize the P and T treatment of MA (minor actinides) and LLFP (long-lived fission products). P and T treatment is possible to make short the period of isolation and realize the zero-release GSC (glass-solidified canister), therefore an unanticipated uncertainty might take place in a super-long period in geologic disposal may be able to be avoided. If P and T treatment can make the requirement for isolation of GSC shorter than 1,000 years, it may be no need to verify the performance of scenario, which will be obtained by the field test for a super-long period. Advanced performance of BTR (burning and/or transmutation reactor) based on 3.3 GWt-HFBWR (high flux BWR) was evaluated to understand the optimum recycle BIT treatment of MA included in the discharged fuel from the current LWR. The separation method in transmutation loop was assumed to be done only by chemical separation, and not by isotope separation. Thus, R and P (reprocessing and partitioning) process can recover MA and separate LLFP as the chemical component level. So, the mass or component, which go out from R and P transmutation loop is only SLFP (short-lived fission product), which was produced by fission reaction.
