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.

This paper describes the density and diameter measurements of silica aerogel microspheres. The aerogel samples were fabricated in the Atomic Weapons Establishment (AWE) Porous Structures Laboratory and by General Atomics. The diameters and densities of the aerogel samples were initially calculated from metrology carried out in the Porous Structures Laboratory. Radiography images of the samples were produced using the Manson soft-X-ray source at AWE from which the diameters and densities of the spheres could be inferred after image digitization.The two different measurement methods are compared, and the results are presented along with statistical analysis showing how well the results corroborate with each other; best practices are established for future measurements and analysis.
