Partitioning and Conditioning Options Based on Chinese High-Level Liquid Waste Full Partitioning Process- 11440

China has decided to construct a large-scale spent fuel(SF) reprocessing plant in about 2020 and fulfill closed nuclear fuel cycle. High level liquid waste(HLLW) is generated as a by product of SF reprocessing, and its management is of great concern. Though vitrification is maturely employed in commercial reprocessing plants, HLLW partitioning is considered as a significant advancement in future reprocessing and promising to be in commission in China’s reprocessing plant. A HLLW partitioning process, so called TRPO process, was proposed in early 1980s and has been in continuous study for thirty years. The most significant milestones in the history of research, development and demonstration on TRPO full partitioning process has been introduced in this paper. All results confirm that the process is effective and feasible to partition minor actinides(MA), Sr and Cs from HLLW. Considering the flexibility of the process and practical separation demands, partitioning and conditioning (P&C) scheme should be determined prior to further work. The process includes feed adjustment in front end, extractive separations and waste conditioning. The most possible four P&C options are introduced in the paper, including process description, material flow calculation and waste forms. In the view of waste reduction, the above four options are discussed.
