| Abstract Scope |
Material deployment for nuclear technologies require extensive testing to understand characteristic degradation resistance within extreme environments. To accelerate experimental study of irradiation resistance in alloys of interest with aims of improving statistical significance in acquired data, a high-throughput method to rapidly irradiate arrays of samples spanning ~150 cm2 up to hundreds of dpa in a single irradiation campaign have been employed. As a proof-of-concept, a plate consisting of a 5x5 array of SS304 samples has been irradiated over the temperature range of 450C-725C. Half of each sample was masked during irradiation, enabling both the irradiated and unirradiated properties of each sample to be characterized side-by-side. Automated 3D optical profilometry, plasma focused ion beam milling, and machine-learning assisted analysis of SEM images is used to quantify void swelling. A comparison between literature and observed trends regarding temperature dependent swelling is then done to determine the viability of this method. |
