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.
Meeting Spotlight

A model is fitted to experimental data by means of a normalizing factor, λ(x), over a range of material compositions, x0 < x < x1. The fitting involves certain modifications of data points. The total discrepancy of the modifications is expressed as δ(x). To an error no greater than δ(x), a model agrees with experiment. Fitting was made to two-group diffusion theory, but the method has general applicability.
