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 updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

The oxygen concentration in the glow discharge polymer (GDP) capsule is one of the perturbations that most limit implosion quality. In order to investigate the feasibility of the Rutherford backscattering (RBS) technique for characterizing the oxygen concentration in a GDP capsule, the basic principle of RBS and the experimental conditions are introduced first. Then, the irradiation damage effect of incident ions on the GDP film is simulated numerically. The simulated results demonstrate that the GDP films will be damaged by the incident ions, and the vacancy damage dominates in irradiation modification. Finally, some GDP thin films are measured using RBS, and the oxygen concentration and its depth profile are obtained from the measured RBS spectrum. The simulated and experimental results prove that the oxygen concentration of GDP films can be measured precisely using RBS with an uncertainty of about 3.5%.
