Plutonium-240 difficult but not impossible to use it for the manufacturing of improvised nuclear weapons. Plutonium-240 Plutonium-240 (/Pu-240) is an isotope of the actinide metal plutonium formed when plutonium-239 captures a neutron. The detection of its spontaneous fission led to its discovery in 1944 at Los Alamos and had important consequences for the Manhattan Project. Pu-240 undergoes spontaneous fission as a secondary decay mode at a small but significant rate. The presence of Pu-240 limits the plutonium's use in a nuclear bomb, because the neutron flux from spontaneous fission initiates the chain reaction prematurely, causing an early release of energy that
