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.

Until recently, the U.S. Nuclear Regulatory Commission (NRC) inspection effort as it applied to transportation casks focused on the written quality assurance (QA) program of cask vendors and subcontractors and U.S. Department of Transportation documentation requirements rather than the implementation of the QA program during the fabrication of the casks. The focus during these inspections has now shifted from a “paper” review to a safety review by a more thorough examination of equipment and the implementation of the QA program during the fabrication of components such as transportation casks. This revised approach to inspections performed by the NRC is reflected in the recent vendor inspections of the defueling canisters and two transportation casks that were designed and manufactured for defueling and transporting the Three Mile Island Unit 2 debris. These inspections identified deficiencies in the fabrication process, and the vendor’s corrective actions resulted in improved controls and an improved product. The transportation of radioactive material will increase in years to come, and it is the responsibility of those who design, fabricate, and use the casks to ensure that a high level of safety is maintained, the requirements are met, and a cask of high quality is used.
