ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.
The Joint Committee on Nuclear Risk Management (JCNRM) is responsible for the preparation and maintenance of voluntary consensus standards, standards-related guidance documents, guidance standards, and technical reports that support the application of risk-informed approaches. These efforts address currently operating and future nuclear power plants and other types of reactors, as well as the transport, storage, handling, and processing of new and used nuclear fuel and radioactive waste. The JCNRM may also support other consensus committees of the American Nuclear Society (ANS) and the American Society of Mechanical Engineers (ASME), and other standards-developing organizations (SDOs), by reviewing and commenting on risk-related aspects of standards, guidance documents, and other documents prepared by those organizations, at their request.
Activities of the consensus committee shall be guided by the Procedures for ASME Codes and Standards Development Committees but shall also meet the intent of ANS Standards Committee Procedures Manual for Consensus Committees unless specifically authorized by the ANS Standards Board.
The JCNRM oversees the following 4 subcommittees:
Volunteer placement is managed by ASME. Individuals interested in JCNRM standards projects may contact Standards for information.
