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 14 MeV neutron transport in spherical iron assemblies is analyzed on the basis of different computational procedures and new double-differential 56Fe cross-sections (DDX) from the ENDF/B-VI and EFF-2 data files. Comparisons with existing integral 14 MeV neutron experiments and with calculations using uncorrected energy-angle distributions show significant improvements due to the inclusion of DDX-data in the recent fusion-oriented data files. Further analyses are required as the total neutron leakages measured in the referenced integral experiments still are underestimated.
