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.

A conceptual design of a passively safe reactor facility for boron neutron capture therapy is presented. The facility configuration and its neutronic, thermalhydraulic, and safety issues are addressed in order to demonstrate the deployability of reactor technology for routine patient treatments and advanced research and dosimetry. The reactor has a power level of <10 MW(thermal) and is based on low-enriched UZrH fuel. The reactor facility generates a clean epithermal neutron beam capable of treating deep-seated brain tumors (∼70 mm) in <10 min. The incident fast neutron and gamma-ray contaminants in the beam are 1.8 and 0.4 Gy, respectively, for a 20-Gy therapeutic dose to a deep-seated tumor. With an expected operation schedule of ∼2000 treatment periods per year, the reactor core lifetime is equal to the 30-yr facility lifetime and no refueling is necessary. Five beam ports are available for simultaneous patient treatments allowing between 2000 and 10000 treatments per year with expansion capabilities of at least threefold for 24 h/day operation. The cost per patient treatment is small, about $1000, making the therapy very affordable. The reactor system design includes several passive safety features that allow the reactor to respond in a safe and benign manner in the event of off-normal transients. The response for various instantaneous reactivity insertions is assessed. Results show the reactor can passively respond to a reactivity insertion of 2 $ such that the maximum temperature limits of the fuel are not exceeded.
