100 years. Plutonium-239 and 241 are fissile, meaning the nuclei of their atoms can break apart by being bombarded by slow moving thermal neutrons, releasing energy, gamma radiation and more neutrons. It can therefore sustain a nuclear chain reaction, leading to applications in nuclear weapons an...

Plutonium-240 has a high spontaneous fission rate, raising the overall background neutron level of the plutonium sample.[83] The original gun-type plutonium weapon, code-named "Thin Man", had to be abandoned as a result—the increased number of spontaneous neutrons meant that nuclear pre-detona...
The facility uses centrifuges to rapidly spin a gaseous form of uranium. Natural uranium is 99.3% Uranium 238 -- a particular variety of the element with 238 protons and neutrons. But weapons require a concentration of at least 90% U-235, a lighter version with three fewer neutron...
The sample contains actinides which, under the effect of the protons, undergo fission, and emit neutrons. The reference 18 indicates a neutron detector unit placed close to the sample 16 in order to detect the delayed neutrons emitted by the sample. The detector unit 18 has several detectors,...
