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.

Through experimental data of total, nonelastic scattering, elastic scattering cross sections, and elastic scattering angular distributions of Sn, a set of neutron optical model potential parameters is obtained. All reaction cross sections, angular distributions, energy spectra, gamma-ray production cross sections, gamma-ray production energy spectra, especially, the double-differential cross section for neutron, proton, deuteron, triton, and alpha emission, and inelastic scattering cross sections and inelastic scattering angular distributions for low-lying residual nucleus states are calculated and analyzed for n + 112,114-120,122,124,natSn at incident neutron energies from 0.1 to 20 MeV based on measured data and the nuclear model theory, which are an optical, semiclassical model of multistep nuclear reaction processes and distorted-wave Born approximation theory. Theoretical calculations are compared with existing experimental data and other evaluated data from JENDL-3.
