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 method for determining the prompt neutron decay constant of a fast critical assembly by noise analysis has been developed. It uses a digital computer to do polarity crosscorrelation on the outputs of two scintillation detectors. For the first time, such a measurement has been made in a fast assembly at criticality with no intrinsic limitation on power level. Portions of the technique were adapted for a study of the dynamics of a digital reactor control scheme.
