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.

The relation between the radial potential profile of the core plasma are examined in the tandem mirror GAMMA 10. It is observed that the radial potential profiles are convex over the cross section of the plasma column and the high energy end-loss ions over the confinement potential are decreased too in many shots. The radial potential profiles were controlled by changing the electrostatic potential profiles of the separated coaxial end plates. On flattening the radial profiles, the reduction of the high energy end-loss ions was softened and the plasma density increased in the central cell. These results suggest that the flattened radial potential profiles decrease the radial diffusion and improve the confinement of the plasma.
