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 the next five to ten years, the use of plutonium-enriched fuels is expected to increase significantly. As is the case with irradiated uranium-only fuels, radiation levels within the reactor system can be expected to increase in the event of a severe fuel failure. The in-reactor dissolution of mixed-oxide UO2-PuO2 fuels has been reviewed with consideration of past experience and potentially useful decontamination solutions. The currently most suitable decontamination agent of mixed oxides is a solution of buffered oxalic acid/hydrogen peroxide/gluconic acid (OPG).
