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.

The CASMO code is an assembly spectrum code that uses multigroup integral transport theory with four thermal energy groups for the two-dimensional calculation. The latest version, CASMO-3, contains several new features, specifically a new data library, multibundle capability, gamma detector calculation, flux discontinuity factor edit, and an option for generating transport theory corrected baffle/reflector data. Extensive benchmarking, including comparisons against cold- and high-temperature critical experiments, Monte Carlo calculations, measured isotopics, and power reactor core follow, has verified that accurate results are obtained. The new multibundle capability has been used for studies of interassembly spectrum coupling and for validation of core physics methods.
