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 effect of stress on the rate of liquid lithium penetration of Armco iron grain boundaries has been determined over a temperature range of 838 to 965 K. The rate of liquid lithium penetration of the Armco iron grain boundary was found to increase with increasing stress for a stress range of 12 to 28 MPa. Specimens stressed to only 12 MPa experienced as much as fifty times the penetration rate of similarly unstressed specimens. The penetration distance has been found to be a single-valued function of creep strain for various combinations of time, temperature, and stress. This relationship of total penetration to total creep strain suggests that the role of stress may be to produce creep strain that ruptures a protective film at the surface, allowing the corrosion rate to proceed at an accelerated rate.
