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 simple yet powerful method is developed to calculate steady-state creep rates in a nonvolume conservative plastic deformation that is linear in the applied stress. The method is applicable to complex stress distributions that exist in many nuclear reactor core components. Application of the method leads immediately to the steady-state creep rates for bending in plane stress and plane strain for a swelling rate that depends on position only through variation in the hydrostatic stress. The bending rate in plane strain can be significantly lower than the corresponding rate in plane stress. The method accommodates arbitrarily spatially varying stress-free swelling rates with only minor generalization. For example, the steady-state stress distribution induced by non-uniform swelling through a tube wall is obtained simply by application of standard formulas for thermal stresses in this geometry.
