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.

A review and discussion of the conditions leading to liquid metal ignition including experimental determination of an ignition envelope for liquid lithium are presented. A simple lumped model is used to investigate the necessary conditions (liquid metal and water temperatures) for liquid metal ignition to be imminent. Both the experimental and model results indicate that as the liquid metal temperature is increased, the water temperature required for interaction to proceed to a vapor phase reaction decreases. A rate equation for the reaction of lithium-lead alloy (Li17Pb83) is determined using a mass transport reaction model. The results indicate that the reaction of this lithium-lead alloy with water can be represented by a parabolic rate law.
