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.

It is proposed that weapons-grade Pu recovered under the strategic arms reduction agreement be used in existing light water reactors under the current safety and licensing criteria. Based on experience with the commercial use of mixed-oxide (MOX) fuel in German pressurized water reactors, MOX fuel assemblies containing weapons-grade Pu have been designed. The related fuel management studies are presented. The possibility of using corresponding hexagonal MOX fuel assemblies in Russian-type VVER 1000 reactors is also discussed. In addition, the use of weapons-grade Pu in modern boiling water reactors is addressed. It can be stated that safe normal operation and benign accident behavior are achievable.
