Differentiation
Value Proposition
Additive manufacturing enables production of safety-related nuclear components that reduce part count, lead time, and cost while improving performance and enabling design freedom unachievable with conventional methods
How They Differentiate
Westinghouse is the only company to have safety-related AM components in serial production for commercial nuclear reactors (first ever). They conducted the first material irradiation study of AM nuclear components (2015), installed the first safety-related AM component in an operating commercial reactor (2020), and have qualified AM processes under nuclear regulatory standards including ASME code cases for additive manufacturing.
