Identification of Tank 50H Solids Components Responsible for Removal of Dissolved Actinides

As part of preparations to use the Tank 50H as a receiving tank for the salt supernate solution designed to feed the Saltstone Facility, a follow up study has been completed to identify the Tank 50H solids components responsible for the removal of plutonium and neptunium from synthetic salt solution. Identification of these sorbents will also help determine whether the existence of these adsorbents is limited to the Tank 50H or more widespread in the High Level Waste system and thus may pose a greater impact
