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.

LOTUS is the name of a test facility dedicated to neutronics integral experiments in blanket assemblies representative of future fusion reactor blankets. It is situated at the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. The main features of the facility and of its 14-Mev high intensity neutron generator are presented, as well as an overview of the experimental program being carried out at LOTUS. Two different types of blanket modules are being tested at the moment: a flexible assembly of different blanket zones, designed at Lausanne, and the Lithium Blanket Module developed at Princeton. Outcome of the first experiments performed with this last module are given, together with results of a preliminary 2-D numerical analysis.
