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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Simulation of reactor antineutrino signatures is vital to verify the experimental measurements of antineutrinos emitted from a reactor. It also provides an insight into detector configurations required to monitor different reactor types and potential fuel diversion scenarios. In this study, we perform simulations of antineutrino signatures for light water reactors (LWRs) using the industry standard reactor simulation tools, CASMO-4 and SIMULATE-3. Three different LWR reactors have been modeled, and several diversion scenarios involving uranium dioxide and mixed-oxide fuel have been simulated. The simulation results are also benchmarked with the antineutrino counts measured by the SONGS1 antineutrino detector that was used to monitor the operation of San Onofre Nuclear Generating Station (SONGS), unit 2, cycle 13, during the period 2004-2005. Three-dimensional simulations of the reactor cores have been performed for improved accuracy of the detector response. The dependence of the antineutrino rate on the reactor type, fuel loading pattern, and amount of fresh fuel have also been analyzed.
