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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

The point design of beryllium capsules includes three Cu-doped layers in a 160-m-thick beryllium shell to achieve the desired X-ray absorption profile. The beryllium capsules were deposited on glow discharge polymer mandrels using a magnetron sputtering process. Cu diffusion during pyrolysis to remove the mandrels after coating has caused nonuniform distribution of Cu along the azimuthal direction due to inhomogeneous diffusion. This nonuniformity along the azimuthal direction could lead to Rayleigh-Taylor instability during capsule implosion. One of the methods to solve this issue is to incorporate a beryllium oxide diffusion barrier layer at the beryllium-Cu-doped-beryllium layer interfaces. In situ and ex situ beryllium oxide layers have proved to be effective in stopping Cu diffusion. This paper will focus on the approaches we have developed to characterize the in situ and ex situ oxide barrier layer thickness by using a combination of Auger electron spectroscopy profiles and Rutherford backscattering spectrometry measurements.
