Structural and Microstructural Characterization of Fission Product Phases in MOX Nuclear Fuel for Fast Neutron Reactors.

Summary: When we use nuclear power, the fuel (a mix of uranium and plutonium) gets used up and creates leftovers called "fission products." Scientists are studying exactly what these leftovers look like on a microscopic level. By understanding these tiny structures, we can do a better job of recycling old nuclear fuel and making future fast reactors safer and more efficient.
