ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

This paper summarizes the 1984 Fusion Power Demonstration (FPD) design study. Three major configurations were investigated. Two were based on the Mirror Advanced Reactor Study (MARS) end cells, which use “C” coil magnets in Yin-Yang pairs to help stabilize the plasma. The third configuration utilized an octopole in the end cell. Detailed studies of major components were underaken and critical issues were identified and examined. Integrated configuration drawings of each of the machines were prepared and are presented here. A Tandem Mirror Reactor Systems Code (TMRSC) was assembled for use in optimizing future device designs but will not be discussed. The various sections of this paper address the mission, goals, and brief design descriptions of the three configurations.
