Electron microscopy characterization of fast reactor MOX Joint Oxyde-Gaine (JOG)
- Idaho National Lab. (INL), Idaho Falls, ID (United States)
The composition and crystal structure of the Joint Oxide Gaine (JOG) is investigated by means of electron microscopy. TEM study of the JOG chemical and structural components is performed. Electron diffraction data, published for the first time in open literature, together with chemical mapping confirm the presence of Cs2MoO4, which is the major component of the JOG. The images reveal a highly heterogeneous porous structure with inclusions containing both fission products and cladding components. Major fission products detected, other than Cs and Mo, are Te, I, Zr and Ba. Fe is found in metallic Pd-rich precipitates with structure compatible with the tetragonal structure of FePd alloy. Cr is found in different locations of the lamellae, in oxide form, but no structural data could be obtained due to local beam sensitization of the sample in those areas.
