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.

Nuclear waste: Trying again, with an approach that is flexible and vague
The Department of Energy has started over on the quest for a place to store used fuel. Its new goal, it says, is to foster a national conversation (although this might better be described as many local conversations) about a national problem that can only be solved at the local level with a “consent-based” approach. And while the department is touting the various milestones it has already reached on the way to an interim repository, the program is structured in a way that means its success will not be measurable for years.

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.
