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.

Samples of different solid materials as well as of water and soil were exposed to the stray radiation field created by a 28.5-GeV electron beam hitting a copper dump. After irradiation, specific activities and residual dose rates were measured at different cooling times from 1 h up to several months. Furthermore, the irradiation experiment was simulated with the FLUKA Monte Carlo code. The calculations included a detailed identification of interaction processes creating the different nuclides. First comparisons of experimental data on specific activities and FLUKA results indicate underestimation by FLUKA at irradiation locations laterally to the target, while the agreement seems reasonable downstream of it. The irradiation experiment, the current status of the data analysis, and a preliminary comparison with FLUKA results are presented.
