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.”

Substituted-ethane diphosphonic acids are an interesting moiety of organic acids because they display particularly favorable chemical characteristics toward the selective dissolution of metal oxides. In recent years, these systems have been studied to develop a cradle-to-grave process for the decontamination of ferrous metals typical of the nuclear power industry. This paper expands the understanding of this system to the dissolution of ferrous oxides found on corroded metals of nuclear facilities.It is found that pure iron oxides such as magnetite (Fe3O4) and hematite (Fe2O3) dissolved quickly (<1 h) using 0.5 M 1-hydroxyethane-1,1-diphosphonic acid (HEDPA) and a strong reducing agent; the oxides with slower kinetics are the spinel structures, such as the nickel ferrites (NiOFe2O3), which dissolved very slowly in the foregoing solution. These results were confirmed in bench-scale tests on actual carbon steel and radioactively contaminated stainless steel samples. The decontamination of actual stainless steel from a nuclear reactor vessel required high concentrations of both HEDPA and reducing agent. Methods for treating the spent HEDPA solution are discussed.
