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.

Neutron scattering cross sections were determined experimentally for more than ten elements in the energy region between 8 and 14 MeV. Comprehensive measuring and data analysis methods were elaborated to obtain cross sections with the highest precision presently possible. The experimental procedure was extended in such a way that cross sections of the complete neutron emission spectrum ranging down to the energy of 1.5 MeV could be derived, thus overcoming the problems usually arising when a nonmonoenergetic neutron source is applied. Typical results are selected for discussion and comparison with the results of other authors and with results taken from several libraries of evaluated neutron data.
