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.
American Nuclear Society meetings and conferences are the best way to keep current with the ever changing fields of nuclear science and technology.
In addition to two national meetings per year, ANS sponsors many topical meetings which concentrate on a particular technical area. Many of these meetings are planned many years in advance and are listed here. To have a meeting listed here, it must be approved by the National Program Committee of the American Nuclear Society for inclusion on the ANS Calendar.
COVID-19 Note: ANS is continuing to monitor the COVID-19 pandemic and its impact on meetings. Please check this page often for meeting status updates.
For more than 65 years, ANS has provided a forum for advancing the state of applied nuclear science and technology. We remain committed to serving the needs of the nuclear professional community during these unprecedented times. In the coming weeks, we will be introducing a new set of digital and video tools that will enable the robust technical exchange of an ANS meeting—papers, presentations, posters, and plenaries, etc.—while ensuring the health and safety of everyone involved during the COVID-19 pandemic.
