Resonant Ultrasound Spectroscopy (RUS) is a powerful means of measuring the elastic modulus of materials very accurately. As such it is a useful tool for characterizing novel materials, measuring the changes in properties due to damage (radiation or otherwise), and as an initial measure of quality in small scale fabrication. This talk will cover RUS measurements on various fuel materials, concentrating on recent results on Uranium Nitride pellets along with some composite fuel materials. Cladding results will be presented, focusing on error analysis in moduli measurements in Zircalloy-4 cladding. Experimental equipment, environment, and challenges while measuring moduli on these materials will be highlighted. Other novel advanced reactor materials, such as metal hydrides and ferritic martensitic advanced reactor cladding materials, will be presented as well.
