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.

Investigations were performed on the aging of five activated carbons in the containment exhaust air of an FRG pressurized water reactor over a period of three months to determine whether longer stay times can be obtained with activated carbons other than that usually employed [207B (KI)] in the Federal Republic of Germany. The aging with respect to the retention of methyl iodide (CH3131I) was smaller with activated carbons impregnated with KIX only than with those impregnated additionally or exclusively with a tertiary amine (e.g., triethylene-diamine). It appears that, for the exhaust air examined, no significantly longer stay times can be presently obtained with activated carbons other than 207B (KI).
