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.

A first-principle model has been developed to perform steady-state and transient analyses of pressurized water reactor plants on microcomputers. The model includes representations for all major components and control systems of the nuclear steam supply systems of plants that have U-tube steam generators. The process of inputting data is simple, and it is easy to set up for simulations of various transient scenarios. The model is accompanied by sophisticated preand postprocessors to help users define or modify input files, start model executions, and analyze output results. It has been benchmarked against plant data and RELAPS for various steady-state and transient scenarios. Satisfactory comparisons have been obtained. Results are presented for full-power steady-state conditions and for a steam generator tube rupture transient.
