U.S. Plutonium Disposition
NNSA is disposing of at least 34 metric tons of surplus U.S. weapon-grade plutonium, as required under the 2000 U.S-Russia Plutonium Management and Disposition Agreement.  This plutonium, enough for thousands of nuclear weapons, will be converted into mixed oxide (MOX) fuel and irradiated in nuclear reactors. This approach will convert the surplus plutonium to a form that cannot be readily used to make a nuclear weapon.  NNSA is building three facilities at the Savannah River Site in Aiken, South Carolina for this mission: the Pit Disassembly and Conversion Facility, the MOX Fuel Fabrication Facility, and the Waste Solidification Building.

Russian Plutonium Disposition
The United States is providing support to Russia for disposing of 34 metric tons of surplus weapon-grade plutonium, as required under the U.S-Russia Plutonium Management and Disposition Agreement.  Russia reaffirmed this commitment to dispose of its surplus weapons-grade plutonium and presented a technically and financially credible approach for Russian plutonium disposition that is consistent with Russia’s national energy strategy, relying upon the use of both existing and planned Russian fast reactors.
