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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The parameters of gas-metal interaction solubility S, diffusivity D and permeability of protium and deuterium in stainless steel 316L have been determined in the temperature range from 600 to 900 K and in the pressure range from 102 to 105 Pa. The results can be presented by: where KS (Sieverts' constant) is given in Pa−1/2, D in m2.s−1, in m2.s−1.Pa−1/2, Po in Pa, T in K and R = 8.31 J.g-atom−1.K−1. The tritium properties have been calculated by application of quantumstatistical partition functions to the solution and diffusion process: The characteristic temperatures of vibration in the ground state, θ = hv/k and in the activated state, θ* = hv*/k have been determined from the measured ratios of protium and deuterium solubilities and diffusivities:
