Correlation between fuel structure and mechanical properties of UO/sub 2/

PDF Version Also Available for Download.

Description

The relation between the structure of a UO/sub 2/ fuel and its mechanical properties are discussed and illustrated for particular types of UO/sub 2/ by measurements of fracture surface energy, hardness, fracture stress and of compressive deformation at 1870 and 1970/sup 0/K. This gives the background for treating the question whether it is possible to find a simple experimental method for correlating the mechanical properties of UO/sub 2/ before irradiation with those after various irradiation histories. Hardness measurements might be such a method if combined with a detailed structural analysis and sufficient knowledge about the irradiation history.
