Recovery and reuse of residual U-235 and bred U-233 from the High Temperature Gas-Cooled Reactor (HTGR) thorium-uranium fuel cycle will con tribute significantly to HTGR fuel cycle economics and to uranium resource conservation. The Thorium Utilization National Program Plan for HTGR Fuel Recycle Development includes the demonstration, on a production scale, of reprocessing and refibrication processes in an HTGR Recycle Demonstration Facility (HRDF).nThis report addresses process yields and material throughput that may be typically expected in the reprocessing of highly enriched uranium fuels in the HRDF. Material flows will serve as guidance in conceptual design of the reprocessing portion of the HRDF. In addition, uranium loss projections, particle breakage limits, and decontamination factor requirements are identified to serve as guidance to the HTGR fuel reprocessing development program.
