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.

Kentucky legislature sends nuclear bills to governor
Kentucky’s Republican-majority legislature passed a bill this past week that could bring nuclear energy to the “coal-is-king” state as lawmakers broadly seek solutions to reduce carbon emissions. The bill went to Democratic Gov. Andrew Beshear on Monday for final approval.

The neutron flux monitor (NFM) is one of the most important diagnostic systems for ITER. Wide-range measuring algorithm (WRMA) is the core algorithm in the NFM system, which deals with the key task of neutron flux measurement. In this paper, the principle and implementation of WRMA, including counting and Campbelling algorithms, are introduced in detail, with error sources of the two algorithms analyzed. In order to study the performance of WRMA, we established a simulation system for neutron signal processing using MATLAB. According to the principle of neutron pulse distribution, the digital waveforms at different neutron flux levels were simulated as inputs to the WRMA module. The variation of measuring error was studied by comparing the counting and Campbelling results with actual input counting rate. In addition, the effects of different neutron pulse widths on the results of the algorithm were simulated. A preliminary experiment at HL-2A was carried out to validate the algorithm.
