National Nuclear Security Administration August 28, 2020 – Federal Register Recent Federal Regulation Documents

The Department of Energy's National Nuclear Security Administration (DOE/NNSA) is announcing this amendment to the April 2003 Amended Record of Decision (AROD) for the Final Surplus Plutonium Disposition Environmental Impact Statement (Final SPD EIS) (DOE/EIS- 0283). In this AROD, DOE/NNSA is announcing its decision to use the dilute and dispose method to disposition up to 7.1 MT of non-pit plutonium as contact handled transuranic (CH-TRU) waste at the Waste Isolation Pilot Plant (WIPP). This AROD changes the disposition pathway for a portion of the 34 MT of surplus plutonium DOE/NNSA previously announced and decided in 2003 to fabricate into mixed oxide (MOX) fuel. DOE/NNSA prepared a Supplement Analysis (SA) for Disposition of Additional Non-Pit Surplus Plutonium (DOE/EIS-0283-SA-4, August 2020) to inform this decision.
