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.
Meeting Spotlight
ANS Student Conference 2025
April 3–5, 2025

The problem treated in Part I in terms of a continuous µ-variable is here treated in the double-PN approximation for azimuthally symmetric situations. Exqplicit representations for basic matrices are derived. The transfer matrix equations were solved on the CDC-6600. Results are presented for two problems of interest—transmission and reflection from thick slabs and the finite reflector critical problem. Anisotropic scattering is considered in both cases. Tables of typical computing times are presented.
