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.

In a steady-state operation, the Next European Torus fuel system must process more than 20 mol/h of gas with minimal production of solid wastes and environmental releases. Requirements, operating conditions, and resulting options for plasma exhaust and fuel processing are discussed. An integrated process for exhaust pumping, impurity removal, and impurity processing is outlined. This process is based as much as possible on proven elements, or those under intensive investigation in fusion facilities around the world. The integration of a cryogenic roughing pump with helium pump-through and total reflux of the electrolyzer products are novel process enhancements.
