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.
Meeting Spotlight

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.

Europe and the Far East have been using refuse-to-energy plants to power turbine generators in the production of electricity. If the U.S. would convert the total municipal refuse to energy at normal efficiency, 6% of the total U.S. electric production could be produced. Pelletized solid waste [refuse-derived fuel (RDF)] can be mixed with coal and burned in existing industrial spreader stoker-fired boilers. An RDF-to-coal volume ratio of 1:1 corresponding to a weight ratio of 40:60 and an energy ratio of 23:77 was burned in a completely unmodified steam plant without unusual variations in equipment operation for a 24-h period. In addition, there was significant reduction in both SO2 and HC emissions compared to low-sulfur coal. Difficulties were experienced with an RDF-to-coal volume ratio of 2:1. Control data were established for comparative purposes by burning coal for a 24-h period.
