Hanford Waste Physical and Rheological Properties: Data and Gaps

摘要: The Hanford Site in Washington State manages 177 underground storage tanks containing approximately 250,000 m3 of waste generated during past defense reprocessing and management operations. These contain a mixture sludge, saltcake supernatant liquids. insoluble sludge fraction the consists metal oxides hydroxides contains bulk many radionuclides such as transuranic components 90Sr. saltcake, by extensive evaporation aqueous solutions, primarily dried sodium salts. supernates consist concentrated (5-15 M) solutions potassium include 149 single-shell (SSTs) 28 double -hell (DSTs). Ultimately wastes need to be retrieved from for treatment disposal. SSTs minimal amounts liquid wastes, Tank Operations Contractor is continuing program moving solid interim DSTs.
