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.

The VG 30–38 mass spectrometer was purchased as the main analytical instrument for the new tritium facility at AWE Aldermaston. Numerous tests were performed on the instrument to determine its ultimate performance. The instrument was initially housed in a non active laboratory in the current facility. After several months of testing the instrument was transferred to the new facility. The new facility is currently undergoing its non active commissioning phase. On installation, a programme of work was performed on the instrument to show that it's performance still met both the manufactures and AWE's specification. After completion of this work the instrument was shut down awaking handover of the facility from the building contractor to AWE. The instrument will be switched on towards the middle of 1995 for the commencement of the active commissioning.
