| Abstract Scope |
Uranium-molybdenum (U-Mo) alloys are used as nuclear fuels in high performance research and test reactors and are under consideration for use in fast reactors. Typically, U-10wt.%Mo is stabilized in the body-centered cubic phase during fabrication since it exhibits favorable isotropic swelling behavior during irradiation. This research explores the early stages of irradiation response to low fluence neutron irradiations from 0.01 dpa to 1 dpa in U-10wt.%Mo at 150 – 350oC. The nanostructured phase decomposition and irradiation-induced defects are discussed as revealed via advanced transmission electron microscopy techniques, including S/TEM high-angle annular dark field and bright field, as well as energy dispersive X-ray spectroscopy. The results are compared to synchrotron X-ray diffraction and scanning electron microscopy examinations of the identical specimens. |
