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.

Session Chair:
Eva E. Davidson
Session Organizer:
With increased high-performance computing (HPC) capabilities, multiphysics codes for reactor applications can be powerful in simulating complex reactor behavior for advanced reactors and the current fleet of light water reactors. There are many advantages to simulating reactor behavior with multiphysics codes, and they can aid in the design and licensing of reactor concepts. However, there are challenges to coupling codes simulating various physical phenomena including working with different time scales, meshes, units etc. which will be discussed. In addition, the panel discussions will include additional issues such as verification and validation of multiphysics codes and software usability by analysts who are not subject matter experts in all physical phenomena being simulated.
