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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

The current National Ignition Facility (NIF) ignition target design consists of 18 precisely assembled components. At the center of the target is a capsule fill tube assembly (CFTA), the baseline of which comprises a Be:Cu or CH:Ge multilayer capsule attached to a glass tube that is used for filling the capsule with hydrogen fuel. The current CFTA has 45 specifications that need to be precisely measured, which are grouped into capsule specifications and attachment specifications. Recent modifications to the tools and the procedures for metrology of these specifications have been implemented and are described. These changes resulted from the experience that the CFTA fabrication team had during production in the early hohlraum energetics campaign on NIF; the evolution of these modifications is discussed.
