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.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

Open field line region plays the key role for steady state operation of the Large Helical Device (LHD) and greatly contributes to the high-performance plasma confinement in the LHD. Chaotic field line region, produced by high magnetic shear and nonaxisymmetry of the magnetic field, is present in open field line re gion outside the last closed flux surface (LCFS) of the LHD. The chaotic field line layer can sustain ambient plasma due to the long connection length of lines of force, presence of the embedded magnetic islands and mirror confinement effect of helical ripple nature of the magnetic field. This ambient plasma plays a role of an impregnable barrier for the core plasma, which suppresses both the MHD instabilities and the cooling of the core plasma due to charge exchange processes. Slow and small periodic sweeping of magnetic axis po sition can control the deconcentration of divertor heat flux in the LHD.
