In September 2000, the United States and the Russian Federation entered into an
agreement stipulating that each country would irreversibly transform 34 metric tons of
weapons-grade plutonium into forms that cannot be used for weapons purposes. As part
of the United States' commitment, the Department of Energy has developed plans to
dispose of 8.4 metric tons of the plutonium and convert 25.6 metric tons into mixed oxide
reactor fuel. Both operations are to take place at the Savannah River Site (Site).
