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.

This paper proposes a fuzzy method of evaluating horizontal nuclear proliferation risk for more efficient use of the International Atomic Energy Agency's (IAEA's) integrated safeguards (IS). The nuclear proliferation risk Rj of nation j is defined as (1 - j) × (1 - j), where j is the probability of nation j maintaining only peaceful nuclear activities for at least 1 yr, is the probability that the IAEA's IS detect indicators of nuclear explosive device (NED) acquisition activities, and j is the probability that the international community will force nation j to abandon these activities after the indications are detected.Because j is equal to and replaces the concept of nuclear nonproliferation credibility used in previous studies, this paper uses a method of deriving this credibility and converting it into j, which is evaluated using trapezoidal fuzzy numbers. Case studies of four nations currently under the IS reveal that the probability of IS detection of indicators of NED activity can be reduced by several tens of percent for some countries without exceeding the upper limit of horizontal nuclear proliferation risk that the international community had accepted in the past.Therefore, depending on the value of nuclear proliferation risk determined using the fuzzy method, the IAEA will be able to use its limited resources efficiently by reducing unnecessary expenditures for some nations under the IS and reallocating those resources to inspections of other nations without increasing the risk of proliferation.
