Abstract
Thermal transient-test failure data for proto-typic fast test reactor fuel cladding were correlated with failure data from conventional mechanical properties tests. The correlation was developed by the application of a life fraction rule to stress rupture, tensile and tube burst, as well as transient test data and by constructing a Larson-Miller plot which encompasses the stress and temperature range for all four types of tests. The high degree of correlation between the different types of test data indicates that this approach will be useful in the prediction of failures under hypothetical transient conditions. It is shown that the Dorn parameter can be used instead of the Larson-Miller parameter with equal success for the various types of mechanical properties tests.
