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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Sputter coating of beryllium on spherical mandrels has been used at Lawrence Livermore National Laboratory and at General Atomics to produce graded, copper doped beryllium shells. While these coatings have consistent microstructure and acceptable void content, different coaters produced different results with respect to argon implantation. Each individual system met the requirements for argon implantation, but the deviation from one system to another and from run to run exceeded the variability requirements as specified by the National Ignition Facility target design requirements. We redesigned the fixturing within one system to improve reproducibility. Then, we reconfigured the coaters so that the vertical and lateral alignments of the shells under the gun varied <1 mm between systems. After this process, the systems were able to produce beryllium capsules with radial argon profiles that met specifications and were consistent from run to run and from system to system. During this process we gained insight into the beryllium coating process. The radial argon variation was shown to be dependent on sputter target thickness. We also found that the argon content in the shells was extremely dependent on the position of the shells with respect to the gun.
