Hanford defense waste separation options
The Hanford Site, located in south-central Washington, is a Department of Energy (DOE) installation that began production of nuclear materials for national defense during World War II. Since that time, Hanford has dedicated its resources to defense nuclear materials production, research, and defense nuclear waste management. These activities have generated tank wastes in the form of liquid, slurry, sludge, and salt cake; encapsulated cesium and strontium; dry solid waste; and contaminated soil. Five years later the ROD, resulting from DOE/EIS-0113, defined the disposal requirements for DST waste and strontium-cesium capsules: (1) completion and operation of waste pretreatment facilities, (2) vitrification of HLW into a borosilicate glass form for ultimate disposal in a geological repository, (3) solidification of LLW as grout for permanent disposal in near-surface vaults at the Hanford Site, and (4) continued storage of encapsulated strontium and cesium until a geologic repository is ready to receive them.
