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.

Research by Gast and Bournia on nuclear reactor cores in the form of elliptical cylinders is revisited. Derivations are presented, and data are extended in scope and accuracy. Findings on asymptotic series for constants needed in the evaluation of Mathieu functions are reported, along with accurate alternative techniques. Geometric bucklings are expressed in terms of circular cylinders with equivalent surface-to-volume ratios in a form that allows easy interpolation from tables. The estimation of extrapolation distances at boundaries of elliptical systems is addressed. Applications considered include a possible research reactor, the damage of fuel storage/shipping casks, and decommissioning of the damaged Windscale reactor.
