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.

Brian D. WirthDepartment of Nuclear Engineering, University of Tennessee, Knoxville
Brian D. Wirth will introduce the Metallurgy and Materials Science sessions with a discussion of "Multiscale Materials Modeling of Radiation Damage and Defect/Microstructural Evolution in Materials: Impact of He/dpa Ratio" The presentation will focus on the effect of a noble gas, helium, which is produced by alpha decay of plutonium, and how that influences the long-term aging behavior of plutonium, including changes in thermal-physical properties. The expected behavior of plutonium aging due to alpha decay will be compared and contrasted from what we know about helium behavior, and in particular the production rate of helium to displacement damage, from materials used in nuclear energy.
