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 ITER Organization has initiated the process of assessing issues and requirements for data analysis and modeling for the operational program. Many of these requirements are consistent with those currently in research programs in the member countries. ITER will, however, rely more heavily on model predictions to design and develop the pulse sequences used during operations. This places a greater demand on the fidelity of the models and on their experimental validation. Real-time data analysis will be an integral component of the ITER plasma control system. Real-time forecasting of discharge evolution, identification of the approach to operational limits, and disruption avoidance strategies are included in the overall strategy for control and analysis. Because of the long ITER pulse length, we require display of analyzed data and model predictions during the execution of each pulse as the data are being acquired and processed. An integrated modeling and data analysis system with unified methods for data handling and storage will be designed and developed.
