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 thermal-hydraulic design study of the proposed ESPRESSO blanket for the Tandem Mirror Fusion Reactor is presented. Two solid breeder/multiplier configurations have been selected for the study: one with natural Li2O as solid breeder and no neutron multiplier and the other with 30% enriched gamma-LiAlO2 as solid breeder and Be as multiplier. A systematic procedure has been developed which effectively reduces the number of independent parameters to two, namely the neutron first wall loading and the main flow bulk temperature rise. Their effect on the maximum multiplier and breeder temperatures and on the pumping power ratio is investigated. Maximum allowable breeder and multiplier temperature constraints limit the design choice and a design point has been obtained for each case for a given maximum allowable pumping power ratio.
