2. MOX fuel - Wikipedia

   en.wikipedia.org/wiki/MOX_fuel

   Plutonium oxide is substantially more toxic than uranium oxide, making fuel manufacture more difficult and expensive. As plutonium isotopes absorb more neutrons than uranium fuels, reactor control systems may need modification. MOX fuel tends to run hotter because of lower thermal conductivity, which may be an issue in some reactor designs.

3. Fission products (by element) - Wikipedia

   en.wikipedia.org/wiki/Fission_products_(by_element)

   Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.

4. Plutonium - Wikipedia

   en.wikipedia.org/wiki/Plutonium

   Plutonium–gallium–cobalt alloy (PuCoGa 5) is an unconventional superconductor, showing superconductivity below 18.5 K, an order of magnitude higher than the highest between heavy fermion systems, and has large critical current. [46] [50] Plutonium–zirconium alloy can be used as nuclear fuel. [51]

5. Breeder reactor - Wikipedia

   en.wikipedia.org/wiki/Breeder_reactor

   But since plutonium-breeding reactors produce plutonium from U238, and thorium reactors produce fissile U233 from thorium, all breeding cycles could theoretically pose proliferation risks. [61] However U-232, which is always present in U-233 produced in breeder reactors, is a strong gamma-emitter via its daughter products, and would make weapon ...

6. Isotopes of plutonium - Wikipedia

   en.wikipedia.org/wiki/Isotopes_of_plutonium

   Plutonium-240 has a high rate of spontaneous fission, raising the background neutron radiation of plutonium. Plutonium is graded by proportion of 240 Pu: weapons grade (<7%), fuel grade (7–19%) and reactor grade (>19%). Lower grades are less suited for bombs and thermal reactors but can fuel fast reactors.

   Plutonium: The Gods Themselves: Isotope of plutonium; too unstable to exist in our world, but exists naturally in fictional parallel universes whose strong nuclear force is stronger. This is used as a source of energy where turned into 186 W, releasing electrons in the process. [citation needed] Lightest known isotope of plutonium: 227 Pu. Quantium

9. Reactor-grade plutonium - Wikipedia

   en.wikipedia.org/wiki/Reactor-grade_plutonium

   The odd numbered fissile plutonium isotopes present in spent nuclear fuel, such as Pu-239, decrease significantly as a percentage of the total composition of all plutonium isotopes (which was 1.11% in the first example above) as higher and higher burnups take place, while the even numbered non-fissile plutonium isotopes (e.g. Pu-238, Pu-240 and ...
