Salt Cake Waste Fractional Crystallization and Displacement Washing
EMSL Project ID
9991
Abstract
New methods to separate sodium salts of nitrate, nitrite, carbonate, and sulfate from salt-cake waste at DOE’s Hanford Site in Washington State will be investigated. These salts make up the bulk of the radioactive waste stored in Hanford's single-shell tanks. To support Hanford's Mission Acceleration Initiative, these low-activity salts will be separated from the main radionuclides, cesium-137 and technetium-99, so the salts can be processed in a supplemental treatment system rather than in the Hanford Waste Treatment Plant (WTP), which is designed to treat high-activity waste such as the cesium-137 and technetium-99. Separation of the sulfate waste fractions and diversion from the WTP will reduce the load on the facility and allow it to operate faster and more efficiently.
