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.

Advanced Limiter Test II (ALT-II) is an axisymmetric toroidal belt pump limiter scheduled for installation on the TEXTOR tokamak in 1986. ALT-II consists of eight blade segments mounted on adjustable supports located 45° down from the outboard midplane of the torus. The passivelycooled pump limiter is designed to remove 5–10% of the plasma efflux and can withstand heat loads on its leading edges up to 300 W/cm2 for 3 second pulse durations. Engineering analyses for ALT-II include calculations of Lorentz forces that could arise during disruptions and predictions of thermal stresses in the blades. The blades are designed to withstand these conditions without compromising pumping efficiency. Support and drive mechanisms are being designed to operate reliably in TEXTOR with minimum introduction of impurities.
