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.

Possibilities for improving the performance of conventional 60 cm thick uniform composition Fe-H2O shields backed by a B4C layer are investigated. The maximum heating rate in the superconducting coils due to (1) Optimally distributing the Fe and H2O across the shield; (2) Optimally distributing the Fe, H2O and B4C; (3) Using TiH2 as the primary hydrogeneous material; (4) Using tungsten instead of iron; and (5) Using a tungsten-copper composite material instead of tungsten, is found to be, respectively, 1.6, 3.6, 6, 32 and 56 times lower than in the reference shield. The development and use of tungsten-, and TiH2-based composite materials for improving the performance and/or economical attractiveness of radiation shields is proposed.
