The US has about 90 tons of weapons-capable plutonium, while Russia has 128 tons. [1] The US declared 60 tons as excess, while Russia declared 50 tons excess. [1] The two sides agreed that each would eliminate 34 tons. [1] The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity. [2]
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.

Their half-lives range from milliseconds to about 200,000 years. Many decay into isotopes that are themselves radioactive, so from 1 to 6 (average 3) decays may be required to reach stability. [8] In reactors, the radioactive products are the nuclear waste in spent fuel. In bombs, they become radioactive fallout, both local and global. [9]
