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.

NRC’s David Wright visits the Hill and more NRC news
The Nuclear Regulatory Commission is in the spotlight today for three very different reasons. First, NRC Chair David Wright was on the Hill yesterday for his renomination hearing in front of the Senate’s Environment and Public Works Committee. Second, the NRC released its updated milestone schedules according to the Nuclear Energy Innovation and Modernization Act (NEIMA) and the executive orders signed by President Trump last month; and third, as reported by Reuters on Tuesday, 28 former NRC officials have condemned the dismissal of Commissioner Hanson earlier this month.

The PROFIL and PROFIL-2 experiments performed in the Phénix demonstration fast reactor irradiated 130 small separate samples containing almost pure isotopes. These highly accurate experiments are a very specific and powerful source of information on the nuclear data of major and minor actinides and several fission products. Their analysis was carried out using the ERANOS-2.0 code system associated to JEFF-3.0 cross-section data, UKFY3.5 fission yield data, and JEF-2.2 decay data. The consistency of the results demonstrates the overall good quality of the actinide nuclear data and experimental techniques used and points out where specific improvement is necessary: fission yields of 235U on neodymium isotopes; integral capture cross sections of 232Th, 233U, 241Pu, 242Pu, and 241Am (and to a lesser extent, 240Pu and 237Np); and branching ratios for 241Am capture. A similar analysis characterizes the degree of accuracy of the integral capture cross sections of 19 fission products. Future plans include the analysis of two new experiments of the same kind, included in the current Phénix experimental program, and the use of a consistent set (cross sections, fission yields, and decay data) of the latest JEFF-3.1 nuclear data files.
