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 safety analysis and risk assessment of a Tokamak Test Reactor is approached by an iterative, probabilistic, system study methodology, jointly devoloped by ENEAa and CEAb. The first part of this methodology consists of a safety related functional analysis of the plant. That is developed in a quite systematic and exhaustive way, aiming at the identification of all the process functions and their modes of loss, so as to forecast all the possible initiating events of safety relevant accident sequences, and their subsequent evolution. This aim is achieved making use of functional interaction and interface matrices, functional fault trees and event trees. The second part concerns the overall plant risk assessment. This is performed using PRA (Probabilistic Risk Assessment) concepts and methods to work out the probabilistic quantification of the system event trees (and linked fault trees), and the evaluation of the related consequences. The methodology is applied by iterations, following the different stages of the plant design development. The first iteration has been applied to the safety analysis of the “Vacuum”, “Tritium and Fuel Handling”, “Blanket” and “First Wall and Divertor” systems of a Tokamak Test Reactor, with a particular reference to NETc. aThe Italian National Committee for the Nuclear Energy and Alternative Energies. bCommissariat à l'Energie Atmoque, the French Natinal Commissariat for the Atomic Energy. cNext European Torus, IPP Garching, Germany F.R.
