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.

An accurate background cross-section method for nuclear reactor cell homogenization is developed that is based on the very precise moment expansion approximation to the neutron escape probability that we recently suggested. The moment expansion approximation is so devised to properly generalize the equivalence relation that the background cross-section method attains a high accuracy to <1% error for each individual resonance, yet still preserves the very features of universality and simplicity of Bondarenko's method.
