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.”

SnxLiy and PbxLiy eutectic alloys are being considered as liquid breeding materials for nuclear fusion applications. Thus, it is important to understand the interactions that might occur if this alloy were inadvertently to contact water. In an effort to study this interaction, experiments have been conducted with the molten alloys when impacted with a vertical 2.4 m tall column of water at 30°C. The qualitative behavior of Sn75Li25 was compared with similar impacts of other candidate molten metals, specifically a lithium-lead alloy, Pb83Li171. Multiple pressure spikes were produced with Sn and Pb, while essentially only one initial pressurization followed by a few strongly damped minor peaks were observed with the different lithium alloys. Hydrogen production from the lithium water interaction was measured and used to determine the extent of the chemical reaction. Dynamic pressure traces from the physical and chemical reactions are discussed and used to compare the energetics associated with the two different eutectics. It was found that the water/eutectic interactions of Pb83Li17 and Sn75Li25 are quite similar and significantly reduced from that of pure lithium and other reactive metals.
