text: The Pu239 isotope of plutonium is fissile, and works even better than U238.
text: Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to about $4,400 per kilogram.
text: In contrast to the low burnup of weeks or months that is commonly required to produce weapons-grade plutonium(WGPu/239Pu), the long time in the reactor that produces reactor-grade plutonium leads to transmutation of much of the fissile, relatively long half-life isotope 239Pu into a number of other isotopes of plutonium that are less fissile or more radioactive.
text: Some other actinides need more than one neutron capture before arriving at an isotope which is both fissile and long-lived enough to probably be able to capture another neutron and fission instead of decaying.
