The U.S. Department of Energy has issued the first in a series of Records of Decision (RODs) pursuant to the Final Tank Closure and Waste Management Environmental Impact Statement for the Hanford Site, Richland, Washington (TC&WM EIS, DOE/EIS-0391, December 2012). Decisions announced in this ROD pertain to each of the three main areas analyzed in the EIS, i.e. tank closure, decommissioning of the Fast Flux Test Facility, and waste management.
The decision includes retrieval of 99 percent of the waste currently stored in Hanford’s 177 underground storage tanks, landfill closure of the single-shell tank farm systems, and operation and maintenance of the tank farms. For the Fast Flux Test Facility, above-grade structures would be removed and below-grade structures would be entombed. To improve waste management at the site, existing facilities would be upgraded, low-level and mixed low-level radioactive waste from Hanford would be disposed of in an Integrated Disposal Facility, and an additional disposal facility for tank closure waste would be constructed, as needed. DOE will continue to defer the importation of offsite waste at Hanford, at least until the Waste Treatment and Immobilization Plant is operational.
