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.”

As a method to improve the design prediction accuracy by utilizing integral experimental data, the conventional cross-section adjustment method (CA) based on Bayes the- orem is widely used. On the other hand, propositions of the generalized bias factor method (GB) in 2006 and the extended bias factor method (EB) in 2007 have stimulated theoretical study in this field. Subsequently, several new cross-section adjustment methods were proposed: the ex- tended cross-section adjustment method (EA); the cross- section adjustment methods based on minimum variance unbiased estimation (MVUE), which include the MVUE- based rigorous EA (MREA) and the MVUE-based rigorous CA (MRCA); and the dimension-reduced cross-section ad- justment method (DRCA). In the present paper, we applied these methods to a real-scale problem of design prediction accuracy evaluation for a large-size sodium cooled fast re- actor and compared their performances. From these re- sults, we discuss a proper use of these design methods.
