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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

The linear extrapolation distance, extrapolated endpoint, and effective radius of grey and black cylindrical neutron absorbers imbedded in an infinite moderator have been calculated using Kofink's formulation of the PN method, with N odd up to 13. These parameters were determined as functions of the absorption of the moderator and of the linear anisotropic scattering component of the moderator, for two source distributions: 1) uniform isotropic sources; or 2) no sources with a current from infinity. The results are given both in tabular form and in simple formulas that are sufficiently accurate for most purposes. In addition, various kinds of PN boundary conditions are compared and new calculations are given for the blackness of homogeneous grey rods.
