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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Simulations of ignition-scale hohlraums show that the addition to the hohlraum of a submicron-thick Au/B interior liner containing [approximately]20 to 40 at. % B likely reduces laser backscatter by reducing the stimulated Brillouin scattering. By reducing the backscatter, the amount of energy available to compress the inertial confinement fusion capsule is increased while the likelihood of laser damage at National Ignition Facility (NIF) is minimized. A specialized magnetron cosputtering process is used to fabricate Au/B liners between 0.6 and 1.2 m for use on hohlraums shot at NIF to the atomic concentrations of 20 to 40 at. % B. We will discuss recent process improvements, such as LabVIEW process automation, in situ rate and thickness measurements, and optimized coating setup, all of which have increased the hohlraum yield and hohlraum throughput as well as increased control and confidence in Au/B liner thickness and B concentration uniformity and reproducibility. We will also discuss effects of various leaching mechanisms affecting B concentration in the Au/B liner.
