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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

The transport of heavy charged particles produced by the 10B (n,α) nuclear reaction is predicted using a mean-range straight-flight model. The slowing down of these particles in a gas adjacent to the coating where they are born is described in terms of their flux energy spectrum, scalar flux, average energy, and energy-loss rate. These results are used in a plasma kinetics model which is compared to measurements of metastable excited state densities in helium and neon plasmas created by the heavy charged particles. The space-dependent fast primary electron (δ ray) energy spectrum produced by the heavy charged particles in helium is calculated, as well as the total number of fast primary electrons and their average kinetic energy.
