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.

Tank waste operations resume at Idaho’s IWTU
The Department of Energy’s Office of Environmental Management announced yesterday that waste processing operations have resumed at the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory Site. The resumption of operations follows the completion of two maintenance campaigns at the radioactive liquid waste treatment facility.

The LIMIT computer code is utilized to study the behavior of containment atmospheres following severe core damage accidents. The degree of heterogeneity in passive entity mixing, especially mass stratification, is assessed. Two scenarios are analyzed using a two-dimensional Cartesian 84-node mesh computational domain as the baseline geometry. Both calculations include steam and liquid fields and involve hydrogen injection. Some stratification is observed after source injections are terminated. The formation of the stable mass gradients is caused principally by heat removal to structures located in the lower regions. Preliminary results conclude that in the absence of sprays or fan coolers, stratification can occur depending on the location and heat capacity of energy absorbing/liberating structures.
