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.”

Nuclear power plants (NPP) haven’t often applied wireless equipment such as mobile terminals and wireless sensors compared with other industries, because wireless equipment need to consider about electromagnetic interference (EMI) to facilities and cyber security. Communication performance has a trade-off relation with security grade and EMI to high important facilities. Further it has become important to conform to security requirements regulated according to security level. We propose a new wireless system which communicates with authenticated equipment in required area where electromagnetic distribution is automatically controlled online, for the purpose of applying wireless equipment in NPP. Electromagnetic distribution is analyzed to communicate only in permitted area and avoid EMI to specified equipment. Each transmitter-receiver wireless modules (WMs) arranged according to the analysis distribution controls its own emission. As a result, electromagnetic distribution is maintained without changing for analysis distribution. In the maintained area, wireless equipment is authenticated and also falsification is detected for their transmission data. Our method based on message authentication code (MAC) reliably carries out authentication and falsification detection for each data packet of transmission data. Further, locations of wireless equipment are identified according to the triangular method applied WMs’ radiation. It is variable for cyber security to monitor each location of wireless equipment which store lager amounts of data. On the subject of cyber security, our wireless system not only carries out authentication and falsification detection at the time of communicating with wireless equipment, but also monitors each location of wireless equipment in required area. We intend to satisfy requirements from NEI and IAEA, further the guideline of NRC such as R.G.1.180 and R.G.5.71 regarding for nuclear facilities.
