Materials Development for Advanced Reactors

Materials development is needed in advanced reactor programs to improve economy and safety of nuclear system components, to provide data for advanced design methods needed for the severe operating conditions, and to nondestructively inspect components under poor accessibility. Interaction between alloy development, stress analysis, and component and system design guides the program on structural materials for core and secondary systems, including steam generators. Various austenitic, ferritic, and high-nickel alloys are being developed for different components.
