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.

A new method is proposed to measure the free volume and the gas content of a pressurized water reactor fuel rod using two expansions of the gas, one at high pressure and the other at low pressure. The gas flow corresponding to these expansions is characterized and modeled. The modeling is then used to prove that this new method is faster and more accurate than the ones usually adopted in hot cells, especially for high-burnup fuel rods.
