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.

A numerical investigation has been conducted to analyze the fluid dynamic aspects of the porous wetted wall protection scheme for IFE reactor first walls. A level contour reconstruction method has been used to track the three-dimensional evolution of the liquid film surface on porous downward facing walls with different initial film thickness, liquid injection velocity through the porous wall, surface disturbance amplitude, configuration and mode number, liquid properties, and surface inclination angle. Here, we report on the effects of evaporation and condensation at the liquid film surface on the dynamics of film flow, the free surface topology, the frequency of liquid droplet formation and detachment, the minimum film thickness between explosions, and the equivalent diameter of detached droplets. Generalized charts, which allow designers of conceptual IFE reactors to identify appropriate "windows" for successful operation of the wetted wall protection concept for different coolants are presented.
