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.

BREAKING NEWS: Trump issues executive orders to overhaul nuclear industry
The Trump administration issued four executive orders today aimed at boosting domestic nuclear deployment ahead of significant growth in projected energy demand in the coming decades.
During a live signing in the Oval Office, President Donald Trump called nuclear “a hot industry,” adding, “It’s a brilliant industry. [But] you’ve got to do it right. It’s become very safe and environmental.”

Just recently, the ARIES team completed the detailed design of ARIES-ACT-1 with aggressive physics and advanced SiC technology. The ability of the SiC/LiPb blanket to provide tritium self-sufficiency was among the important issues investigated in detail. To pinpoint the design elements that degrade the breeding the most, we developed a novel stepwise approach that involves building the CAD model from scratch, and, in multiple steps, adding the internals/externals of the blanket. At each step, the impact on the tritium breeding ratio (TBR) was recorded to identify the more damaging/enhancing conditions or changes to the tritium breeding. The TBR approaches 1.8 for an ideal system, and then degrades to 1.05 for the ARIES-ACT-1 reference design. This paper sheds light on several breeding-related issues that puzzled the fusion community for decades and gives insight about the impact on TBR of the individual blanket internals as well as other essential parts of the tokamak.
