Title: Detailed Analysis of RUS Insertion Experiment and Scoping Studies for Performing Next Experiment using an Enriched Fuel Sample

Abstract

Microstructure evolution due to irradiation in a nuclear reactor can have a dramatic effect on material properties. A better understanding of this evolution is necessary for developing improved nuclear fuels and materials. The ability to measure such changes in real time is extremely challenging due to high temperatures, high radiation fields, and limited access of the reactor environment. Through carefully designed experiments, measurement of elastic properties can be tied directly to microstructure. We present an instrument that has been developed to monitor in-pile changes in grain microstructure. The measurement approach involves optically exciting and detecting flexural waves in a thin cantilever beam. An instrument capsule based on this technique was fabricated and underwent an irradiation test in the TREAT reactor in May 2019. Analyses of the test results are presented in this report. Scoping studies on the expected impact of radiation on similar tests are also presented.
