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.

The main results of several years of research on neutron and gamma-ray physics in the Purdue Fast Breeder Blanket Facility (FBBF) are summarized. Presented are neutron capture rates in 238U, 232Th, gold, tungsten, and manganese, and fission rates in 235U and 239Pu. Neutron spectra are determined from proton recoil energies over the range from 2 keV to 2 MeV. The energy deposition of the gamma-ray field is measured with thermoluminescent detectors. Since the FBBF is a source-driven facility, all results are obtained on an absolute basis and are compared with corresponding calculations. Most of the results are presented as calculated/experimental trajectories except for the neutron spectra. The absolute and complete experimental results will be presented in separate papers. The comprehensive and coherent interpretation of deviations between calculated and experimental results is explored. Three major deviations are identified; they concern the “bulk” of the neutron population, the low-energy wing of the spectrum, and the space dependency of resonance absorption.
