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.

A kinematic scaling system, based on successes found for inclusive electron-nucleus continuum spectra, is developed and applied to (p,px) and (p,nx) data at beam energies from 346 to 1600 MeV. The emphasis is on ejectiles with the highest energies at small angles since these are the particles able to induce further reactions in thick samples of interest for current and future accelerator-driven neutron sources. The limits of the method are explored, and successes are used to identify gaps in the difficult data sets available. Scaling successes are able to allow interpolations and extrapolations needed for applications. Details of the method are presented in appendixes.
