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.”

The shell stabilization of the tilting mode in a moving ring reactor due to the arrangement of a conductor close to the plasma is studied by numerically calculating the stabilizing torque by the eddy current induced on the conductor surface. The tilting mode instability can be successfully suppressed in the slender ring plasma with the aspect ratio of four by either an internal rod conductor or an external annular conductor. The arrangement of both rod-and annular-type conductors is required for stabilizing the tilting mode in a ring plasma with the aspect ratio of three. The effect of the mutual interaction among the eddy current is shown to be so small as to be safely neglected in calculating the eddy current induced by the tilted plasma, and the simplified treatment of the eddy current is suggested for the computation of the stabilizing torque due to the shell effect.
