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.

A 4667-second long discharge has been obtained in the ATF torsatron. The total amount of the energy input was 330MJ. The set-up procedures, the control of plasma parameters, and the effect on the wall conditioning for the long pulse discharge are reported in this paper. Fast density feedback control is not useful for a long-pulse operation; control of the neutral pressure on a slower time scale is necessary. Long-pulse discharges are quite effective for wall conditioning. Valuable experiences have been accumulated in the future experiments planned for LHD.
