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.

Magnetic flux surface measurements have been carried out in the Large Helical Device (LHD) in the standard magnetic field configuration with toroidal magnetic field strength up to 2.75 T. An electron beam launched with a small electron gun moving across the flux surfaces was detected with a fluorescent screen or a probe array. Nested surfaces could clearly be visualized with both methods. Even the stochastic region was detected. In the experiment, unfavorable m/n = 1/1 and 2/1 magnetic islands were discovered near the last closed flux surface, where m and n are poloidal and toroidal mode numbers, respectively. There is a possibility that the source of the error field, in the low magnetic field of 0.0875 T, is terrestrial magnetism. On the other hand, in the standard magnetic field of 2.75 T, the main source of the error field is thought to be ferromagnetic materials near the torus of LHD. Fortunately, it was demonstrated that such magnetic islands can be reduced or eliminated by applying a correction field with some perturbation coils.
