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 Siberian Chemical Combine (Russian: Сибирский химический комбинат) was established in 1953 in Tomsk-7 now known as Seversk, in the Tomsk Region as a single complex of the nuclear technological cycle for the creation of nuclear weapons components based on fissile materials (highly enriched uranium and plutonium).
The plant was considered part of the weapons-grade Plutonium Management and Disposition Agreement signed between the United States and Russia. The reactor is part of the final step for a plutonium -burner core (a core designed to burn and, in the process, destroy, and recover energy from, plutonium) [ 4 ] The plant reached its full power ...

As early as 1910 in Russia, independent research was being conducted on radioactive elements by several Russian scientists. [6]: 44 [7]: 24–25 Despite the hardship faced by the Russian academy of sciences during the national revolution in 1917, followed by the violent civil war in 1922, Russian scientists had made remarkable efforts toward the advancement of physics research in the Soviet ...
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...

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.
