Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The U.S. Nuclear Regulatory Commission’s (NRC) instrumentation and controls (I&C) regulatory infrastructure, established and supplemented over the decades, has addressed many safety concerns and issues as they arise, using the best information and techniques available at the time. As a result, the licensing process for new highly integrated I&C systems and digital upgrades of existing I&C systems has become prescriptive, cumbersome, and thereby resource/time-intensive. In creating a more efficient licensing process for small modular reactors (SMRs), the NRC staff implemented an enhanced safety-focused review approach for the NuScale Power LLC, (NuScale) SMR design. This approach has been successful in the efficient and effective review of the NuScale SMR I&C design. The restructured, safety-focused approach in Chapter 7 of the Design-Specific Review Standard (DSRS) for the NuScale SMR design [1] is a significant step forward for licensing of any future new and advanced reactor applications. Yet, the staff has learned additional insights and lessons that are important to be captured and addressed in order for the agency to be ready for future new light water or advanced non-light water reactor licensing applications. As such, the NRC staff has embarked upon a new initiative to create a performance-based/risk-informed and technology-neutral guidance for future new and advanced reactor design reviews. This paper presents the NRC staff’s initiative to modernize the NRC’s I&C regulatory infrastructure for the efficient and effective licensing of future I&C designs that account for lessons learned and ever changing I&C technologies.
