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.

The pneumatic temperature monitoring system for the Experimental Gas-Cooled Reactor (EGCR) is designed to measure individual fuel channel coolant temperatures during the reactor lifetime. The pneumatic system is superior to a fixed thermocouple system if it can be maintained to operate with the desired accuracy, throughout the reactor lifetime. The initial cost of the pneumatic system, when integrated with the burst fuel element detection system, is less than that for an equivalent replaceable thermocouple system. The in-reactor portion of the pneumatic system is being installed during initial construction of EGCR as a backup for a fixed thermocouple system. The remainder of the system may be installed after initial reactor operation, to determine whether long term operation and maintenance is economically feasible.
