The detection of its spontaneous fission led to its discovery in 1944 at Los Alamos and had important consequences … Meer weergeven The inevitable presence of some Pu in a plutonium-based nuclear warhead core complicates its design, and pure Pu is considered optimal. This is for a few reasons: Meer weergeven About 62% to 73% of the time when Pu captures a neutron, it undergoes fission; the remainder of the time, it forms Pu. The longer a nuclear fuel element remains in a nuclear reactor, the greater the relative percentage of Pu in the fuel becomes.
