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 ARIES team is presently studying a fusion power plant based on the spherical tokamak (ST) concept. This paper addresses the key nuclear issues for spherical tokamaks and illustrates the impact of the neutronics factors on the ARIES-ST design. A three-dimensional analysis was carried out for an interim design to determine the key nuclear parameters. Preceding the 3-D analysis, a series of parametric 1-D analyses were performed to guide the design toward the final configuration. Comparing the 1-D and 3-D results, important differences were identified and attributed mainly to the angular distribution of the incident source neutrons on the first wall. Those differences are unique to spherical tokamaks.
