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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

In its elevated-temperature critical-assembly experiments, the University of California Radiation Laboratory, Livermore, will utilize stainless-steel-clad fuel elements. The fuel element consists of 0.001- or 0.002-in. thick enriched-uranium foil packaged in a welded 0.002-in. thick type-347 stainless-steel envelope. The design requirements for the fuel elements are stated, as are the considerations which led to the design selected. Beta heat treatment of the uranium was found necessary to provide compatible thermal-expansion characteristics for the two materials in the fuel element.
