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.

The validity of the transport approximation is checked for systems which cannot be treated by the diffusion approximation and deviations of the transport approximation from exact calculations are evaluated by means of a perturbation formula. It is concluded that even for critical systems of dimensions of the order of the transport mean free path the transport approximation yields good results.
