【 摘 要 】

This work discusses the operational envelope developed for tests involving in-situ formed magnetite to remove strontium (Sr) and actinide from Savannah River Site (SRS) waste solution. These tests will be performed at Argonne National Laboratory (ANL) in support of the SRS effort for HLW treatment. The operational envelope was developed in consultations with key personnel at SRS. Four elements of the operational envelope were identified: (1) waste simulant composition, (2) radionuclide concentrations and oxidation states, (3) minimum DF requirements, and (4) the maximum amount of magnetite that can be used per liter of waste.
