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.

UIUC microreactor fuel qualification methodology gets safety approval
The University of Illinois at Urbana-Champaign Nuclear Plasma and Radiation Engineering (NPRE) Department announced yesterday that the Nuclear Regulatory Commission has approved a fuel qualification methodology topical report for the high-temperature gas-cooled reactor the university wants to construct. The topical report was prepared by Ultra Safe Nuclear and submitted by UIUC to the NRC in March 2024. It describes the fuel that would be used in the microreactor that UIUC plans to host—initially containing uranium enriched to 9.9 percent U-235—and how it would be tested. The NRC issued its approval and a final safety evaluation on April 1.
