EIS-0220: Supplemental Record of Decision

Interim Management of Nuclear Materials

After further review of stabilization costs, schedules, and program requirements, DOE has decided to implement the Processing and Storage for Vitrification in the Defense Waste Processing Facility alternative as well as the Process to Oxide alternative previously selected for the management of the H-Canyon plutonium solutions. The environmental impacts of the newly-selected alternative were analyzed in the IMNM EIS. This alternative includes the transfer of the solutions to the SRS high-level waste (HLW) system, vitrification of the liquid HLW in the Defense Waste Processing Facility, and storage of the resultant canisters in appropriate waste storage facilities at the SRS pending disposal in a geologic repository.
