There are many isotopes of Plutonium. Pu-238 has a half-life of 88 years and is used in Radioisotope thermoelectric generators. That's the isotope that's running out. A lot of the other isotopes will be around for many many years. We have more of those than we need. https://en.wikipedia.org/wiki/Isotopes_of_plutonium https://en.wikipedia.org/wiki/Isotopes_of_plutonium So, of course, we come up with schemes to get rid of them, like blending some in with other nuclear fuel. Such as what we did in Unit 3 at Fukushima Daiichi. And then hydrogen gas caused massive explosions, releasing radioactive material. Oops.
