Plutonium-239 Fission

²³⁹Pu + ¹n → ¹³⁴Xe + ¹⁰³Zr + 3¹n

Tổng quan

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.
