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

Self-shielding and edge corrections were investigated for varying thicknesses of 1 cm dia. gold foils. Test foils were irradiated in the hohlraum or air chamber of the Cornell University TRIGA Mark II reactor. The self-shielding effect was determined from the activation of a series of foils of different thicknesses and the edge correction from the activities of successively smaller concentric rings punched from the parent foil. Edge effects were found in the 2.5 mil and thicker foils and were statistically significant only in the outer millimeter of the foil radius. After cutting off the outer millimeter of the foils, the activity was found to follow the ½ − E3(t∑a) law for infinite foils.
