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 analysis of neutron spectra emitted from a 14-MeV source and streaming through a void steel duct embedded in concrete is carried out using a multigroup Monte Carlo code on a small computer. The calculated results are compared with experimental results and with other calculational analyses involving continuous energy Monte Carlo methods. The computational methods agree when the Pn expansion of the multigroup method is sufficiently extended. Some discrepancies with the experimental results, found in earlier analyses, still remain; and these are investigated with regard to the use of a new modification of the evaluated iron data, the spreading of the calculated results for comparison with experimental spectra, and various other modeling details.
