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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

Passive gamma scanning (PGS) for detecting the variations in relative PuO2 content (composition) in (U,Pu) mixed oxide (MOX) fuel pins with low PuO2 content (0.4%) for pressurized heavy water reactors is demonstrated. Experiments are carried out with MOX pins of varying compositions with a NaI(Tl) detector. An annular detector was used to improve the counting statistics, and it was demonstrated that a change of PuO2 content of ±0.02% could be detected at a very low level of PuO2 content of 0.4%. It was also observed that a larger-sized PuO2 agglomerate of 1 mm located near the surface of the pellets could be detected during PGS of the welded fuel pins.
