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.

Twelve experimental runs on molecular iodine removal by sprays were carried out in the 95m3 PSICO 10 model containment vessel (MCV). Both service water and a water solution containing 1% sodium thiosulphate were sprayed through two different nozzles; the elemental iodine removal half-times obtained by spraying service water do not differ greatly from those found by spraying thiosulphate solution. The sprayed solution was, in some cases, recirculated for a period ranging from 1 to 11 h without any release of iodine to the atmosphere. Some runs were performed with fractions of the MCV volume not sprayed. The elemental iodine removal half-times in the sprayed and unsprayed regions do not essentially differ.
