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.

New Ohio board part of momentum for state-driven nuclear development
Ohio Gov. Mike DeWine recently made new appointments—including American Nuclear Society members Raymond Cao of Ohio State University and Alicia Walls of BWX Technologies—to the Ohio Nuclear Development Authority.
The nine-member governor-appointed board was created in June 2023 by state lawmakers aimed at boosting research and development of advanced nuclear reactors, commercial isotope production, and nuclear waste reduction and storage technology. The group has initial funding of $750,000.

A nondestructive radioactivity assaying apparatus, especially suitable for miscellaneous waste drums, has been developed. The apparatus employs a simplified computed tomographic technique in the analytical process. The method uses 10 × 10 (horizontal) × 9 (vertical) density and radioactivity distribution information measured by Nal(Tl) detectors and an external source to compensate for photo-peak count rates from a germanium detector. Methods to compensate for the inhomogeneity of miscellaneous solid wastes are discussed. A detailed comparison of the proposed method with two other simplified methods, using >200 kinds of mockup wastes, showed an improvement in measurement precision for the proposed method over the conventional methods. The overall precision for measurements on the untreated miscellaneous waste was evaluated to be within 30% when using the proposed method.
