Surplus Plutonium Disposition Supplemental Environmental Impact Statement


ANNOUNCEMENT - March 30, 2016

Today I signed the Record of Decision (ROD) for Disposition of Surplus Non-Pit Plutonium for the Final Surplus Plutonium Disposition (SPD) Supplemental Environmental Impact Statement (Supplemental EIS).

The ROD outlines the Department of Energy’s National Nuclear Security Administration (DOE/NNSA) path forward to prepare and process six metric tons (MT) of surplus non–pit plutonium at Savannah River Site (SRS) for disposal at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico.

SRS and the State of South Carolina are vital to meeting national security and nonproliferation objectives. The uniquely qualified, highly trained workforce at SRS are among the foremost experts in the safe and secure disposal of nuclear material. Implementing this mission will require the installation of new equipment at the site and the hiring and training of additional technical personnel. After the material is diluted, the plutonium will be disposed of at WIPP, using a proven process that has been used in emplacing the nearly 5 metric tons of surplus plutonium currently at WIPP.

The SRS community performs an invaluable service that would not be possible anywhere else in the world.

The Department remains committed to preparing and removing plutonium from the State of South Carolina. The signing of this ROD represents the formal adoption of the path forward for final removal and disposition of 6 MT of plutonium from SRS.

ABOUT THIS PROJECT

To reduce the threat of nuclear weapons proliferation, the U.S. Department of Energy (DOE) is engaged in a program to disposition U.S. surplus, weapons-usable plutonium in a safe, secure, and environmentally sound manner, by converting such plutonium into proliferation-resistant forms that can never again be readily used in nuclear weapons.

The Surplus Plutonium Disposition Supplemental Environmental Impact Statement (SPD Supplemental EIS) analyzes the potential environmental impacts of alternatives for the disposition of 7.1 metric tons of additional weapons-usable plutonium from pits ("pit plutonium"; a pit is the core of a nuclear weapon) that were declared surplus to national defense needs in 2007 and were not included in DOE's prior decisions and 6 metric tons of surplus, weapons-usable non-pit plutonium.

DOE evaluates the potential impacts of four action alternatives: (1) Immobilization to the Defense Waste Processing Facility (DWPF) Alternative – glass can-in-canister immobilization for both surplus non-pit and disassembled and converted pit plutonium and subsequent filling of the canister with high-level radioactive waste (HLW) at DWPF; (2) MOX Fuel Alternative – fabrication of the disassembled and converted pit plutonium and much of the non-pit plutonium into MOX fuel at MFFF for use in domestic commercial nuclear power reactors to generate electricity, as well as potential disposition of the surplus non-pit plutonium that is not suitable for MFFF as contact-handled transuranic waste at the Waste Isolation Pilot Plant (WIPP); (3) H Canyon/HB Line to DWPF Alternative – processing the surplus non pit plutonium in H Canyon/HB Line and subsequent vitrification with HLW (in DWPF) and fabrication of the pit plutonium into MOX fuel at MFFF; and (4) WIPP Alternative – preparing for potential disposal as contact-handled transuranic waste at WIPP the surplus non-pit and disassembled and converted pit plutonium in H Canyon/HB-Line and K Area at the Savannah River Site (SRS), or preparing the surplus non-pit plutonium in H Canyon/HB Line and K-Area at SRS and preparing the surplus disassembled and converted pit plutonium in TA-55 facilities at the Los Alamos National Laboratory (LANL).

Currently, surplus pit plutonium is not in a form suitable for disposition and must be disassembled and converted to an oxide. Pit disassembly and conversion options analyzed in this Final SPD Supplemental EIS are: (1) a stand-alone Pit Disassembly and Conversion Facility (PDCF) at F-Area at SRS; (2) a Pit Disassembly and Conversion Project (PDC) at K-Area at SRS; (3) a pit disassembly and conversion capability in PF-4 in TA 55 at LANL and metal oxidation in MFFF at SRS; and (4) a pit disassembly and conversion capability in PF-4 at LANL with the potential for pit disassembly in K-Area, conversion in H Canyon/HB-Line, and metal oxidation in MFFF at SRS.  

This SPD Supplemental EIS evaluates disposition alternatives that include irradiation of MOX fuel in TVA reactors, subject to appropriate amendments to the applicable licenses from the NRC. TVA is a cooperating agency for this SPD Supplemental EIS and, as such, is not required to declare a preferred alternative. TVA does not have a preferred alternative at this time regarding whether to pursue irradiation of MOX fuel in TVA reactors and which reactors might be used for this purpose.
