Plutonium recovered from LWR spent fuel, while not weapons grade, can be used to produce nuclear weapons at all levels of sophistication, [25] though in simple designs it may produce only a fizzle yield. [26] Weapons made with reactor-grade plutonium would require special cooling to keep them in storage and ready for use. [27]
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 production in August 2016. [5] According to Russian business journal Kommersant, the BN-800 project cost 140.6 billion rubles (roughly 2.17 billion ...
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]
Apr. 14—It's been almost 80 years since the first atomic bomb was detonated, and scientists say there's still much to learn about how nuclear devices function as they reach the point of exploding.
The use of plutonium affects weapon design due to its high rate of alpha emission. This results in Pu metal spontaneously producing significant heat; a 5 kilogram mass produces 9.68 watts of thermal power. Such a piece would feel warm to the touch, which is no problem if that heat is dissipated promptly and not allowed to build up the temperature.
Plutonium recovered from nuclear weapons or other sources can be blended with uranium fuel to produce a mixed-oxide fuel. In June 2000, the US and Russia agreed to dispose of 34 kilotonnes (75 × 10 ^ 6 lb) each of weapons-grade plutonium by 2014. The US undertook to pursue a self-funded dual track program (immobilization and MOX).
