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 neutronic feasibility of testing fusing firstwall/blanket systems in a fission reactor is investigated. Heating rates resulting from a 14-MeV fusion source are calculated with one-dimensional transport theory for two tokamak blanket designs and compared with heating rates computed for the same blankets in the Engineering Test Reactor (ETR). The designs studied are a gas-cooled, liquid-lithium blanket with no neutron multiplier and a water-cooled, solid lithium-aluminate blanket with a beryllium multiplier. Based on these preliminary results, it is concluded that bulk heating rate profiles expected in tokamak reactor blankets can be simulated quite well in large (65- × 76- × 91-cm) blanket experiment modules placed on one side of the ETR core. Heating rates corresponding to tokamak wall loadings of 1 MW/m2 can be achieved, and the level varied to simulate the cyclic operation typical of tokamaks.
