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.

State legislation: Colorado redefines nuclear as “clean energy resource”
Colorado Gov. Jared Polis signed a bill into law on Monday that adds nuclear to the state’s clean energy portfolio—making nuclear power eligible for new sources of project financing at the state, county, and city levels.

Three recent experimental campaigns at Los Alamos National Laboratory have required unique application of traditional machining techniques to manufacture the components. For pRad experiments at Los Alamos Neutron Science Center (LANCE), unique planar targets with varying profiles required unique fixturing: a custom programming software to create concentric rings with a 2-deg taper that had five different sine waves machined across the face. Also, experiments using P8 modulated capsules for Asymmetric Burn Experiment (ABEX) experiments at Omega made use of a water-soluble ultraviolet-curable glue, which was used for holding and locating purposes during machining operations to produce an indicating datum, as well as a custom fixturing system, which allowed the ability to apply the impression gum from behind. Finally, for the milling of a 125-m-thick silica aerogel for dense-plasma equation-of-state experiments, we used an ultraprecision milling machine with a high-speed spindle and precise positional accuracy that permits micrometer depth of cuts at higher feed rates, which allowed for a reduction in machining time.
