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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

The 2014 International Handbook of Evaluated Reactor Physics Benchmark Experiments (IRPhEP Handbook) spans over 30 000 pages and contains 136 evaluations. In the handbook, evaluations are grouped by reactor type (light water reactor, heavy water reactor, liquid metal cooled fast reactor, etc.) and contain up to ten different types of measurements, each of which can be applied to code and nuclear data validation. Despite the thoughtful organization and strict format rules for evaluations, identifying suitable validation cases remains challenging. To assist with searching and trending the IRPhEP Handbook, a relational database and user interface named IDAT (IRPhEP Database and Analysis Tool) was developed. IDAT was first distributed with the 2013 edition of the IRPhEP Handbook and will be updated annually as evaluations are added and revised. Data characterizing the measurements were extracted to allow for searching and trending in IDAT. Measurement types in the database include criticality, buckling, spectral characteristics, reactivity effects, reactivity coefficients, kinetics, reaction rates, and power distribution measurements. Additionally, the database contains calculated quantities, such as neutron flux/capture/fission spectrum data, neutron balance data, and keff sensitivity data, along with tools to visualize these data. IDAT can employ data to assist in the identification of similar experiments using a variety of metrics, within a “Rank Similar” pane. For each measurement in the database, there is also a “Trending” pane, allowing multilevel plots of calculated over experimental values allowing users to drill down by applying various filters. This paper describes the creation of IDAT as well as its features.
