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 since 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. local time 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.”

An expanding cascaded arc plasma is used for the deposition of different types of carbon layers at high growth rates. Single diamond crystals of 60 µm and 25-µm-thick continuous films are deposited within 1 h on areas of ∼5 cm2. In recent experiments, pyrolytic graphite films have been deposited. Films up to 200 µm thick have been produced within 20 min on an area of ∼12 cm2. The film type and growth rate depend on the choice of the optimum reactor parameter settings. To maximize the growth rate and crystallinity of the film, the reactor settings are varied. High growth rates (maximum of 762 nm/s) have been obtained at high temperatures (600 to 1000°C). Several diagnostic techniques are used to analyze the film. The purity of the films has been confirmed by Auger electron spectroscopy.
