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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The integration of nuclear assessment (neutronics, shielding, and activation) is an essential element to the success of any fusion design and represents a major issue for power plant studies in particular. High fidelity in nuclear results mandates performing state-of-the-art nuclear analyses. This has been achieved in recent years through coupling the computer-aided-design system directly with three-dimensional neutronics codes to preserve all geometrically complex design elements and speed up feedback and iterations. This paper outlines several major nuclear issues addressed for the recently completed ARIES-ACT1 tokamak conceptual power plant study. An integral nuclear approach was deemed necessary to deliver an optimal design. This approach considered the overall configuration, design requirements (including tritium self-sufficiency), smart selection of low-activation material for all components, radial build optimization and definition, and safety and environmental concerns. This paper reports the main results of this integral approach that aims at considering several effects that influence the global behavior of a complex power plant such as ARIES-ACT1.
