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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

An electron temperature and a volume-averaged plasma density are experimentally investigated for various argon gas pressure and rf power in permanent-magnets-expanding plasma sources with two different diameters of 6.6 cm and 13.3 cm for the purpose of performance improvement of a electrodeless, magnetically expanding plasma thruster. The results are compared with a global model using particle balance and power balance equations. The theoretical values are in fair agreement with the measured ones. The experimental and modeled results suggest that a ~50 percent increase in the thrust from the electron pressure can be achieved by the enlargement of the source diameter from 6.6 to 13.3 cm.
