플루토늄-239 핵분열
239Pu + 1n → 134Xe + 103Zr + 31n
개요
Plutonium-239 undergoes neutron-induced fission similar to U-235 but with slightly higher energy release. Pu-239 is produced in reactors when U-238 absorbs a neutron and undergoes two beta decays. MOX fuel (mixed oxide of Pu and U) is used in some commercial reactors to consume excess plutonium.
