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 China Fusion Engineering Test Reactor (CFETR) is the next tokamak device in China to bridge the gaps between ITER and the DEMOnstration nuclear fusion reactor (DEMO). The CFETR vacuum vessel (VV) was designed to remove nuclear heating, provide safety shielding, and maintain a high-quality vacuum environment. Seismic load is considered one of the most relevant accidental events affecting the structural integrity of the VV. In order to investigate the resistance of the CFETR VV against seismic load, finite element models of the VV were built. In this paper, equivalent static and response spectrum analyses were carried out to calculate displacements and stress fields aiming to check the response of the CFETR VV against a foreseen seismic load. The resulting stresses are lower than the allowable limits and satisfy the design requirements.
