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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Acoustic oscillations in nuclear steam supplies have caused structural vibration leading to plant modifications in both pressurized water reactor and boiling water reactor (BWR) systems. Power increases (i.e., uprates) in some BWR designs have resulted in acoustic oscillations in the steam supply that have caused fatigue failures in steam dryer assemblies. Standing waves in side branch lines are identified as one important acoustic source for waves in the main lines. The side branch standing waves are driven by vortex shedding across the branch opening. The side branch lines couple acoustically with standing waves in the main line, extending the range of physical behavior beyond that normally considered in the literature. There are many side branches mounted where there is flow in the main steam line, creating multiple acoustic sources, many of nearly the same frequency. These multiple sources cause time variation in the acoustic performance that may extend over many seconds, and these attributes must be considered during data acquisition, component load simulation, and stress simulation. Wet steam sound speed models appropriate to BWR steam supply conditions are also presented.
