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 Fokker-Planck equation for the transport of energetic charged particles in hot plasmas and for one-dimensional plane geometries is solved by a new multigroup approach. The numerical scheme proposed here takes into account the strong anisotropy of the Coulomb scattering operator, as well as the possible large values of the removal cross section. Numerical results are given for two particular examples: the transport of protons in a boron hydride plasma and of 3.5-MeV alpha particles in a deuterium-tritium plasma. A good agreement is achieved with corresponding results from a less general “moment method” developed in previous works.
