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 development and application of two quantitative methods that could be used as part of the decisionmaking process in the licensing of nuclear power plants are described. These methods are (a) the use of quantitative screening criteria to assess the adequacy of the safety functions in existing plants and (b) the use of value/impact or cost /benefit analysis to determine limits to the cost-effective expenditure on“back-fitting” to improve safety. It also is shown that the results obtained by the two methods are not necessarily compatible with one another. As an example, the two methods are applied to the question of improving the decay heat removal function for light water reactors. Screening criteria are presented for this function for both pressurized water reactors and boiling water reactors. The value/impact assessment is carried out as a function of site population, existing plant features, and new plant features.
