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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Using 14.7-MeV neutrons and gamma-ray spectroscopy with high-purity germanium detectors, the activation cross sections have been measured for the following nuclear reactions: (a) 44Ca(n,p)44K, = (39 ± 4) mb; (b) 44Ca(n,np)43K, = (3.0 ± 0.3) mb; (c) 44Ca(n,)41Ar, = (31 ± 3) mb; (d) 42Ca(n,p)42K, = (138 ± 12) mb; (e) 43Ca(n,p)43K, = (90 ± 9) mb; and (f) 48Ca(n,2n)47Ca, = (613 ± 60) mb. A 98.6% enriched 44Ca target was used for reactions (a), (b), and (c) and a natural calcium target for reactions (d), (e), and (f). These cross sections have been compared with some earlier published experimental values and with some results of calculations. The latter include those based on semiempirical formulas and those given by the preequilibrium plus compound-nucleus code GNASH. When applied to reactions (a), (d), (e), and (f), this code gives cross-section values that are consistently above the measured values.
