The mechanical properties of UO2 fuel are of great importance to the nuclear engineering community for modeling of fuel performance during operation and accident scenarios. Data on the deformation of single crystals at room and elevated temperature can help these efforts by informing multiscale models. Small-scale testing techniques like microcantilever bending and nanoindentation have the ability to measure mechanical properties at the right length scale for this, while allowing the observation of the deformation of the material. In our work we perform microcantilever testing of UO2 at room temperature and nanoindentation testing up to 500 C, as well as in-situ TEM microcantilever testing.
