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 RadBall is a 140-mm (5.5-in.)-diam deployable, passive, nonelectrical gamma hot-spot imaging device that offers a 360-deg view of the deployment area. The device is particularly useful in instances where the radiation fields inside a nuclear facility are unknown, but a suitable decommissioning strategy is required to be planned. The original version of the technology had a number of drawbacks including a relative insensitivity to radiation (at least 3 Gy required), which led to long deployment times, as well as a narrow target dose range (3 to 8 Gy), which meant that the user required prior knowledge of the radiation fields in which the device was to be deployed. The United Kingdom's National Nuclear Laboratory has developed the technology to overcome both of these issues. The developments associated with the new technology are described here, as are some recent tests undertaken at the Sellafield facility in the United Kingdom. The work has resulted in a significant improvement in sensitivity - 150 times - as well as greatly widened the target dose range to between 20 mGy and 50 Gy. The new version of the technology therefore has a much-improved applicability compared to the original technology.
