Decontamination of Dissolved Salt Solution from Tank 19F Using Duolite CS-100 and Amberlite IRC-718 Resins

摘要

The high level alkaline waste generated at SRP is separated and stored as solid and liquid fractions in underground tanks. In the proposed flowsheet for the Defense Waste Processing Facility (DWPF), the solid fraction (sludge) will be sent to a glass melter for fixation in a borosilicate glass matrix (DWPF - Stage 1). The liquid fraction (supernate) will be processed through ion exchange columns where the major radioactive isotopes (Cs137 and Sr90) are removed (DWPF) - Stage 11. This report describes a demonstration of ion exchange decontamination of defense waste from Tank 19F in the High Level Caves (HLC).
