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.

ARIES ACT-1 is a conceptual design for a commercial tokamak with aggressive physics and engineering. In the spirit of advanced engineering, the vacuum vessel design employed several novel concepts. It eliminates the use of water cooling in order to allow higher temperature operation and reduce the tritium inventory. It employs a low activation bainitic steel that eliminates the need for post-weld heat treatment. It includes sufficient volume to accommodate a full loss of coolant accident. Finally, it employs a novel mechanical design in order to withstand the operating stresses during normal operation, anticipated transients, and disruptions. In this paper, we present the most recent design for this component, update the stress analysis confirming the suitability of the design, and present results for disruption forces due to a plasma quench.
