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.

A phase-shifting diffraction interferometer provides full surface mapping of National Ignition Facility (NIF) ablator capsules for surface finish and isolated defects. To integrate this new instrument into the NIF metrology work flow, the measurement must be both quick and accurate. In this work, we developed automated processing algorithms to streamline a large number of manual steps. This enables the process time to be reduced from 1½ days to 2 h per shell, thus meeting the NIF throughput requirement of 20 capsules/week. We also developed methods to quantitatively report the isolated defects and surface roughness in formats that can be benchmarked against the NIF specifications.
