| Abstract Scope |
According to the Nuclear Energy R&D Roadmap Report, one the key challenges facing the nuclear energy industry involves development of innovative reactor designs to reduce capital costs which requires making improvements in the affordability of any new reactors and development of structural materials to withstand irradiation for longer periods. In this research we are developing a laser additive manufacturing (LAM) method and process model that provides in-situ tempering of a Grade 91 (Gr 91) steel, a radiation tolerant steel, during LAM. Initial work includes producing Grade 91 samples using Direct Energy Deposition additive manufacturing at Optomec Inc. and heat treating and characterizing tempered Grade 91 to develop and benchmark the process model being developed to predict the microstructures produced through additive manufacturing. |
