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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Large glass shells (≥ 1200 μm diameter) made by the traditional drop tower technique are usually thin walled (≤ 4 μm). Therefore, even the highest quality shells cannot hold more than ∼70 atmospheres (atm) of gas pressure. This report describes the strengthening of these shells by over-coating them with Glow Discharge Polymer (GDP). Glass shells overcoated with various thicknesses of GDP were permeation-filled and burst tested. It was found that tens of microns of GDP overcoating significantly increased the strength of the original glass shells. In particular, composite shells able to hold 200 atm of helium were made. The burst test survivors were tested against possible undetected microcracks by confirming that the half-life for the release of the gas from filled shells was consistent with the expected half-life for an intact shell.
