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 inherent shortcomings of the subchannel analysis were analyzed, and an alternative approach using volume porosity, surface permeability, and distributed resistance and heat source was developed. The volume porosity, surface permeability, and distributed resistance and heat source approach has advantages over the subchannel analysis because of the use of orthogonal coordinates and geometrically similar control volumes for both axial and transverse momentum equations. Furthermore, it can readily be reduced to the volume porosity and distributed resistance and heat source approach, which is the only viable method for thermal-hydraulic analysis for large rod bundles.
