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 initiation of straight breakdown paths has been identified as the key issue of the LIB propagation channel formation scheme in the HWIFR dense atmosphere. Straight preionization trails have been suggested as means for guiding the breakdown along the designated beamlines. A multi-group Boltzmann equation solver has been constructed for estimating the capability of several preionizers to induce such trails in dense D2O vapors. A new approach capable of predicting the steady state streamer wave shape is used to estimate the minimum conditions for launching a streamer in the preionized path. The electrical resistance of the trail during the streamer propagation is evaluated with a simple one dimensional routine. Finally the transition of the streamer-induced ionized filament to a multi-kA-carrying plasma channel is simulated with a modified radiation MHD code. Other results of this study, including the determination of the preionizer intensity and the minimum applied potential required for the initiation, are presented in this paper.
