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.

Criteria for nonlinear asymptotic stability of nuclear reactor systems repre-sentable by point reactor kinetics are derived. The reactor system model includes all delayed neutron precursors and linear feedback. The results are also extended to systems where the feedback is not linear., A procedure is outlined for the interpretation of the criteria by means of small-amplitude perturbation tests. The procedure is illustrated by using experimental transfer function measurements from Experimental Boiling Water Reactor.
