| Abstract Scope |
Radiation-induced degradation of materials properties is the showstopper for advanced reactor concepts, making licensing of designs without data on the performance of core structural materials the biggest challenge to deployment. Industry is facing the prospect of not being able to acquire the data they need to support license applications because of the lack of test reactor availability and the amount of time it takes to obtain the required data. The solution to this obstacle to rapid deployment is ion irradiation in combination with advanced characterization and predictive modeling. This talk will describe the development of a predictive tool that incorporates ion irradiation and computational materials modeling to determine the microstructure and mechanical properties of core structural materials, benchmarked against reactor data, and codified in ASTM standards, thus providing licensees with a justification of the efficacy of their core material performance in their safety case to the regulator. |
