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 nominal 1500 STP-L PAssively Cooled, Electrically heated hydride (PACE) Bed has been developed and tested. The bed contained 12.6 kg of a La-Ni-Al alloy and used aluminum foam to improve heat transfer within the bed. Steady-state temperature measurements made at constant power showed a nonuniform bed temperature profile. Protium absorption rates were measured at pressures of 253 kPa, 413 kPa, and 680 kPa with forced convection cooling air flow rates ranging from 50 to 150 SLPM air. Absorption tests were also performed simulating the absorption of tritium and a method for estimating this rate using protium absorption data presented. Desorption rates were measured at pressures ranging from 20 kPa to 933 kPa using dual and single 400 watt electric heaters and found desorption rates were only impacted at the beginning and the end of a desorption cycle by the use of a single heater.
