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.

A variety of shaped fill holes is needed in beryllium capsules for inertial confinement fusion experiments to allow for pyrolysis of the plastic (CH) mandrels, deuterium (D2) or deuterium-tritium gas fill, and fill tube attachments. The holes required include through-holes ranging in diameters from ~5 to 30 m and counterbores ranging in diameters from ~13 to 17 m with depths <37 m. These holes are laser drilled using a double-pulse nanosecond format. Hole diameter and depth can be controlled by altering pulse format, energy, and beam delivery optics. Furthermore, according to National Ignition Campaign specifications, there is a tight tolerance for perturbations on capsule surfaces, so we have developed a technique to eliminate material redeposition through the use of sacrificial foils stretched over the targeted areas.
