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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

A characteristic method for transport calculations in two-dimensional geometries has been developed as a part of the interface-current transport code TDT. A complete description of angular and spatial approximations, as well as numerical implementation is given. A new synthetic acceleration technique has also been developed based on piecewise uniform and isotropic approximations for cell entering and exiting fluxes. Fourier analysis of the accelerated iterations shows the potential of the new acceleration scheme. Numerical results for one-group and multigroup problems involving realistic assembly geometries prove the performance of the acceleration in realistic unstructured geometries.
