Plutonium is a Actinide metal. It has a Monoclinic crystalline structure. It does not have any isotopes considered to be natural. Its longest-lived known isotope has an atomic number of 244 with a half-life is 80 million years.[1] . This element has no stable isotopes. Plutonium 239 can be blended with Uranium 238 to make a mixed oxide fuel for electrical power production.[2] Mixed oxide fuel with 7% plutonium 239 and the balance mainly Uranium 238 is equivalent to uranium oxide fuel with about 4.5% uranium 235 enrichment.[3]
