Regulatory history of non-light-water reactors in the U.S.
A cutaway view of EBR-1.
Over the past several years there has been renewed interest in the development and licensing of advanced reactors that will be very different from the light-water reactors that are currently used to generate electricity in the United States. For example, some advanced reactors will use gas, liquid metal, or molten salt as a coolant, some will have a fast neutron spectrum, and some will be much smaller in size than current generation LWRs. The many possible applications for these reactors include electricity production, process heat, research and testing, isotope generation, and space applications.
To prepare for potential non-LWR application submittals, the U.S. Nuclear Regulatory Commission has studied the issues and written many new relevant documents. In addition, there is a long history of the NRC regulating non-LWRs that might be useful to study to help in addressing new submittals. To some extent, this has been chronicled in general histories of the NRC. Our objective herein is to describe the NRC’s history specifically with the licensing of non-LWRs and to explain some of the most salient regulatory and licensing issues.
“This program has allowed me to learn more about nuclear science outside of the classroom and sparked my interest in nuclear science.”
— Richard, High School Student and Center Program Participant
We deliver on a promise: distill the complex world of nuclear into information that is accurate and engaging. The Center’s message is online, in the news, up on Capitol Hill, and across the desks of students and teachers from coast to coast.
