The Plutonium Management and Disposition Agreement is an agreement between the United States and Russia signed in 2000, wherein both nations agreed to dispose of significant fractions of their "excess" (beyond what they need for their nuclear weapons) weapons-grade plutonium. [1]
To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.
The government says it will dispose of its 140 tonnes of radioactive plutonium - currently stored at a secure facility at Sellafield in Cumbria. The UK has the world's largest stockpile of the ...

Although plutonium has uses other than the manufacture of weapons, the United States later insisted that South Korea not attempt to reprocess plutonium in any way. In exchange, the US agreed to transfer reactor technology and give financial assistance to South Korea's nuclear energy program.
According to a proposal by the United States, fissile material includes high-enriched uranium and plutonium (except plutonium that is over 80% Pu-238). According to a proposal by Russia, fissile material would be limited to weapons-grade uranium (with more than 90% U-235) and plutonium (with more than 90% Pu-239).
