Title: A METHOD OF CORRELATING IRRADIATION EFFECTS IN DISPERSION FUELS

Abstract

A method of correlating irradiation effects in dispersion fuels was proposed in which the effects of irradiation conditions are considered independently of material variables. Two simple failure models were devised (failure by creep and by short-term stress yield). Criteria which permit estimates of the relative severity of tests made under different test conditions but on identical specimens were developed. Numerical application of the procedures for 18-8 stainless steel with 25 and 30 wt.% UO/sub 2/ specimens was attempted. No positive verification of the short-term stress model was obtained, but the creep model yielded the approximate failure limits for both specimen compositions. (auth)
