ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Complementary methods may be used to solve the neutron transport problem. When only a small amount of information is needed, the most efficient method is obviously Monte Carlo. However, when perfect knowledge of the full phase-space is required, it is worth using a deterministic technique. Nevertheless, this memory and CPU time intensive approach may soon overwhelm even the most powerful computer. To deal with these issues, an adapted mesh refinement transport scheme was developed that solely retains active areas of a geometry. The computer code Styx, built on this efficient set of numerical methods, specially designed and tuned to run on such a tree-based topology, is presented. A test case subset, representative of the wide spectrum of multidimensional applications it covers, is then analyzed.
