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 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. 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.”

In order to evaluate the effect of cusp magnetic field in the cylindrical Radially Convergent Beam Fusion (RCBF) device, four kinds of experimental setups were examined. The maximum Neutron Production Rate (NPR) of 7.4 x 109 n/s was obtained at -80 kV and 15 A. As a result of the theoretical evaluation of fusion regimes in the RCBF device, the NPR normalized by the cathode current and the gas pressure was compared between the setups. The experimental data showed that the normalized NPR is highly correlated with the gas pressure, and it was independent of the setups. As the gas pressure decreased, the normalized NPR was increased. Hence, the present study suggests that the effect of the cusp magnetic field is to achieve lower pressure operation which improves the normalized NPR. The numerical estimation became in agreement with the experimental result by introducing an adjusting factor which was highly correlated with the pressure. The difference of the pressure is expected to affect some factors, such as an effective cathode transparency.
