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.
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.

UWC 2020: A call for transformational change
Bowing to current COVID-19 realities but buoyed by the success of June’s virtual Annual Meeting, ANS event planners returned to the virtual realm for this year’s Utility Working Conference. Originally scheduled for August 9–12 at Marco Island, Fla., the condensed event was held Wednesday, August 11, wherever registrants’ computer devices happened to be located.
In addition to 26 educational sessions and workshops, UWC 2020 featured an opening plenary session titled “Achieving Transformational Change: A leadership discussion,” moderated by Bob Coward, MPR Associates principal officer and ANS past president (2017–2018). Plenary panelists included representatives from three utilities—Arizona Public Service (APS), Exelon, and Xcel Energy—plus the Institute of Nuclear Power Operations (INPO) and the Nuclear Regulatory Commission.

Neutral beam injection is one of the main auxiliary heating methods in controllable nuclear fusion experiments. During the operation of the EAST neutral beam injector, a large amount of energy is deposited on the ion source components, especially the electron dump (ED). In this paper, the energy deposited on the ion source components was analyzed in arc discharge mode and beam extraction mode indirectly by calculating the energy taken away by the cooling water. The results show that the ED has a large heat load: the average power density is almost 4.5 MW/m2 when the beam power is 3.3 MW. This research may lay the foundation for increasing the heat transfer capacity and guide the optimization of the ion source components in future work.
