Abstract
Two multi-stage FCOs which incorporate thorium-based fuels in HWRs have been examined for their potential, one which uses recycled PWR uranium oxide fuel in conjunction with thorium in an HWR, and another that uses recycled HWR fuel in an MSR which also includes thorium. Both of the systems studied offer resource utilization improvements as compared to a once-through LWR fueled with low-enrichment uranium and highlight the potential synergy of thorium and HWRs.

Calculations were performed for various combinations of U-235 enrichments and burnups to optimize equilibrium compositions. To carry out the necessary depletion calculations, the TRITON depletion module of SCALE was used. SCALE is a comprehensive modeling and simulation suite for nuclear safety analysis and design (developed and maintained by ORNL under contract with the U.S. Nuclear Regulatory Commission, DOE, and the National Nuclear Security Administration) [11]. The primary capabilities of SCALE relevant to this analysis are two-and three-dimensional radiation transport and depletion analysis. This work is supported by the U.S. Department of Energy, under the Nuclear Energy University Program. The work is being carried out as Project No. DE-NE0000735, ?Development of Fuel Cycle Data Packages for Thorium Fuel Cycle Options?.
