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.

This manuscript reports the high density plasma production with a pair of phase controlled ion-cyclotron range of frequency antennas in GAMMA 10. For the plasma production, the Radio Frequency (RF) power (~10 MHz) is coupled to the fast Alfvén wave in the central cell. The antenna-plasma coupling depends strongly on the antenna structure. In this study, according to the numerical prediction, a pair of double half-turn and Nagoya Type-III antennas is adopted for the excitation of the fast wave. The antennas are driven at the same frequency with controlling their phase difference. It is observed that an optimum phase difference exists in the present density range. The density increases with the RF power and the gas-fuelling rate, when the phase difference is set to the optimum value. The considerable increase in the density was obtained up to twice as large as the conventional value.
