SESAME 96171, a three-phase equation of state for CeO2
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
This report describes an earlier version of an equation of state (EOS) for cerium (IV) oxide, CeO2. This work has been superseded by a newer version that is described in LA-UR-14-24689. Everything from this report needed to understand the new version is included in the new report. I have constructed SESAME 96171, an EOS for cerium (IV) oxide that includes two solid phases and the liquid. Unlike its immediate predecessor, this EOS is valid over a larger range in pressure due to including the extra phase. I have described the process of constructing and testing the EOS, emphasizing its continuity with the previous EOS and the modifications needed for the new frame-work. The comparison with data is good, but is still limited by the same issues with nuclear models that were present in the previous work. The remaining significant issue is the comparison of the crystal-density EOS with experimental porous Hugoniot data, which may require using more sophisticated model to represent porosity, as discussed in the previous report.
