プルトニウム240
1. Plutonium-240Plutonium-240 (Pu-240) is an isotope of the metal plutonium formed when plutonium-239 captures a neutron. About 62% to 73% of the time when Pu-239 captures a neutron it undergoes fission; the rest of the time it forms Pu-240. The longer a nuclear fuel element remains in a nuclear reactor the greater the relative percentage of Pu-240 in the fuel becomes.
