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.”

In January 2007 the World Nuclear Association (WNA) established the Cooperation in Reactor Design Evaluation and Licensing Working Group (CORDEL) with the aim of stimulating a dialogue between the nuclear industry and nuclear regulators on the benefits and means of achieving a worldwide convergence of safety standards for reactor designs. CORDEL is comprised of several technical working groups including the Digital Instrumentation and Control Task Force (DICTF). Soon after CORDEL was established, the DICTF identified safety classification as a topic where a better understanding of the regulatory practices in various countries could improve the nuclear industries’ ability to license new nuclear power plant designs in various countries. One of the issues identified was the need to understand inconsistencies between the safety requirements established by international and national codes and standards. The first step in this effort was to examine the formally defined terminology that the various organizations use to define five key concepts: Defense-in-depth and diversity, Separation, Redundancy, Reliability, and Spurious activation. This paper summarizes the approach and conclusions of this study. We found important inconsistencies both between the terms that various organizations use for the above key concepts and the definitions of the key concepts themselves. We also found, however, that some of the existing definitions encompass the ideas of all of the organizations studied. Therefore, we believe that it is possible to establish common terms and definitions for the five concepts. This work may also represent a prototype methodology for harmonizing terms and definitions used for other key concepts.
