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 is devoted to discussing the technical characteristics of pulsed plasma-focus (PF) generators and their features as fusion reactors as an alternative for stationary thermonuclear installations. First, the authors present results of experimental data obtained on the Pulse Plasma Accelerator–30 (PPA-30) and dense PF-4 devices. The pulse discharge current and jumped parameters and the energy distribution along and across the axis on the 31-kJ (at 30 kV and 69 μF) PPA-30 device were determined. It is indicated that plasma already is completely ionized at the kilo-ampere range and its inductance is small. The maximum energy density of the plasma was equal to 230 J/cm2 and a macrofocusing effect was observed. Second, the emission parameters of the PF-4 device were determinate. The neutron yield was equal to about 107 imp/shot. The variation of the axial and radial neutron yield was observed. Further, the problems of neutron yield on PF devices and options for the development of a fusion reactor taking into account other technical capabilities of PF are discussed. It is proposed to develop the design of PF in such a way as to take into account the peculiarities of the interaction of particles with an electric and magnetic field. In this situation, the important indicator is not the temperature of the plasma, but the geometry of the electrode system to provide a directed flow of particles.
