In 2017, NIA published a report about using the Major Portions option to establish regulatory finality of part of a reactor for a Standard Design Approval. This Addendum provides lessons learned from NIA's observation of a pre-application interaction by Terrestrial Energy USA that drew upon NIA's original report.
The Nuclear Innovation Alliance and Partnership for Global Security have a developed a joint strategy for U.S. leadership on commercialization of advanced reactors. A whole-of-society approach with collaboration between government, industry, civil society, and other nations can bring advanced reactors to market to reduce global emissions, provide domestic jobs, and support national security.
In recent decades, the nuclear industry has become increasingly global, with companies and technologies flowing across borders. An early provision in nuclear law limits the ability of US allies to invest in nuclear innovation in the US. Repealing that provision, or allowing an exception for close allies, can unlock financing and other collaborations to enable the US nuclear sector to remain globally competitive.
