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 JET project at Culham, Oxfordshire, UK, part of the Euratom Fusion Programme, is regulated by Her Majesty's Inspectorate of Pollution (HMIP) with regard to the holding of radioactive materials and the disposal of radioactive waste. JET has had to justify the holding of radioactive material and their radioactive waste management plans to HMIP. JET have been authorised by HMIP to discharge radioactive waste within limits and under specified conditions in order that national and international radiation dose limits to members of the public are not exceeded. There is an overlying requirement by HMIP that the discharges are limited by the use of the best practicable means (BPM) so that radiation exposures from JET's discharges are kept as low as reasonably achievable (ALARA). The HMIP Inspector has powers under the Radioactive Substances Act 1960 which allow him to inspect JET and carry out any relevant tests or measurements. The Inspector also ensures that JET has an appropriate monitoring programme in order to assess radiation doses in the environment.
