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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

A stellarator-mirror fusion-fission hybrid has recently been proposed. Neutral beam injection (NBI) is here studied numerically for this hybrid using a two-dimensional kinetic code, KNBIM. The code accounts for Coulomb collisions between the hot ions and the background plasma. The geometry of the confining magnetic field is arbitrary for the code and is accounted for via a numerical bounce averaging procedure. Along with the kinetic calculations the neutron production intensity is computed.The calculated hot ion distribution function from NBI is used in power balance estimates for the whole system. The requirement that the fast neutrals should be efficiently captured in the plasma is imposed to restrict the range of plasma parameters. The results obtained balance calculations are close to results obtained previously with a bi-Maxwellian ion distribution function. The calculated parameters for a power producing stellarator mirror device and within modern top technical capabilities. The parameters of plasma and NBI characteristics seem also attainable. The calculated fusion Q is within a range with potential for energy production in a hybrid reactor.
