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 expanding cascaded arc plasma is used for the deposition of different types of carbon layers at high growth rates. Single diamond crystals of 60 µm and 25-µm-thick continuous films are deposited within 1 h on areas of ∼5 cm2. In recent experiments, pyrolytic graphite films have been deposited. Films up to 200 µm thick have been produced within 20 min on an area of ∼12 cm2. The film type and growth rate depend on the choice of the optimum reactor parameter settings. To maximize the growth rate and crystallinity of the film, the reactor settings are varied. High growth rates (maximum of 762 nm/s) have been obtained at high temperatures (600 to 1000°C). Several diagnostic techniques are used to analyze the film. The purity of the films has been confirmed by Auger electron spectroscopy.
