Technetium Oxidation State Adjustment for Hanford Waste Processing

  • Chapter

Abstract

Technetium, as the pertechnetate anion (TcO4 −), is a very mobile species in the environment.1 This characteristic, along with its long half-life, (99Tc, t1/2 = 213,000 a) makes technetium a major contributor to the long-term hazard associated with the storage of low level waste (LLW) forms.2 Thus, technetium partitioning from nuclear waste stored at DOE sites (Hanford, Savannah River, Melton Valley, etc.) may be required so that the LLW forms meet the DOE performance assessment criteria for storage.
