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.

The successful outcome of the liquid-metal leak test was a key event in the MEGAPIE (MEGAwatt PIlot Target Experiment) project, a multinational endeavor aimed at developing a reliable neutron spallation source operating with dense liquid metal. Indeed, the leak test validated the containment design, which was a regulatory requirement for demonstrating that a liquid-metal source could be operated safely. Furthermore, unique temperature and stress measurements were recorded that agreed well with test predictions published ahead of the test. This paper outlines the approach taken for predicting the consequences of a liquid-metal leak, with particular emphasis on a simplified one-phase calculation method that may be useful in the future for predicting the impact of accidental liquid-metal leaks at modest expense in terms of CPU time.Most of the assumptions underpinning the original analytical predictions necessarily erred on the conservative side. Therefore, the boundary conditions applied to the original analysis, such as the exit flow rate of the liquid-metal jet, are critically reviewed in this paper to improve on the existing agreement between the predictions and the experimental data.
