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.

Fusion reactor facilities will be required to minimize releases of hazardous materials to the environment during both normal operations and accident situations. The Tritium Systems Test Assembly (TSTA) at the Los Alamos National Laboratory has a tritium removal system, capable of processing room air to collect tritium accidentally released into the tritium handling areas of the facility. This system, the Emergency Tritium Cleanup (ETC) system, will both minimize accidental releases to the environment from TSTA and demonstrate the feasibility and operations of a large room air detritiation system. The system is also designed to study tritium releases under controlled conditions. Based on the initial nontritium tests described in this paper, we have determined that the ETC has a single-pass efficiency for tritium collection of greater than 99.9%.
