Bases, Assumptions, and Results of the Flowsheet Calculations for the DecisionPhase Salt Disposition Alternatives

摘要

The HLW salt waste (salt cake and supernate) now stored at the SRS must betreated to remove insoluble sludge solids and reduce the soluble concentration of radioactive cesium radioactive strontium and transuranic contaminants (principally Pu and Np). These treatments will enable the salt solution to be processed for disposal as saltstone, a solid low-level waste.
