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.

The ANSI/ASME/ANS "Probabilistic Risk Assessment Standard for Advanced Non-Light Water Reactor Nuclear Power Plants" was approved and published January 28, 2021. The development of the Non-LWR PRA Standard encountered many technical issues that the working group overcame, such as: database development for the 1,500+ requirements; combining PRA elements from multiple PRA standards into one comprehensive PRA standard; formation of absolute importance measures and screening criteria; and appropriate language to allow PRA applications over the entire design/operation life cycle. This panel will discuss these technical issues and the lessons learned from the development of the Non-LWR PRA Standard.
