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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

A method based on the Rayleigh-Ritz or Galerkin technique is presented for obtaining domains of linear stability in terms of the parameter space for space-dependent reactor dynamics models. The method developed is computationally economical because previous calculations are retained as the order of approximation increases. In addition, the method reduces to finding the eigenvalues of a matrix so any standard procedure can be used.,The method is applied to data typical of a fast and a thermal reactor with fuel and coolant feedback. One group of delayed neutrons is also included.
