Description
Summary:Aiming at TRU waste arising reduction and economical competitiveness for the future reprocessing, is proposed an advanced process concept which is named PARC (Partitioning Conundrum Key) process. Enhancement of confinement capability for long-lived nuclides in a simplified Purex process is the primary subject of this R&D project. Technologies for long-lived nuclide recovery are under development, focused on 14C and 129I in head end, 237Np and 99Tc in extraction, and 241Am the daughter of 241Pu in effluents. Those nuclides focused here are mobile in the environment and highly concerned as potential hazardous among the long-lived nuclides in spent fuels. New functions in PARC process concept are designed to mitigate the environmental impacts of reprocessing wastes and also to improve economy of reprocessing in the future.
