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.”

A Fuel cleanup system (FCU) that recovers fusion fuel (tritium and deuterium) from plasma exhaust mixture gas has been developed and demonstrated at the Tritium Process Laboratory (TPL) of Japan Atomic Energy Research Institute (JAERI). We have proposed a new closed loop FCU system built up by connecting the tubular reservoir tank, the electrolytic reactor and a palladium diffuser. In the electrolytic reactor, methane and water are converted at the same time by electrochemical reaction in gas phase oxidation and reduction to liberate hydrogen isotope as a form of elemental hydrogen. The long tubular reservoir tank that is designed to store and transfer the products gas in plug flow prevents from mixing with reactants for the successive repeat processing. With this tank, high overall decontamination factor of system can be obtained by small number of circulation. As the demonstration test, mixture gas consist of hydrogen isotopes, methane and He were processed in the closed loop FCU. The electrolytic reactor and the tubular reservoir tank worked as designed successfully, and the entire loop exhibited efficient impurity processing performance. The concentration of methane was observed to decrease sharply in every processing by the electrolytic reactor from 2.3% to less than 12ppm finally.
