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.

We are proposing to connect a supercritical CO2 gas turbine (SCOT) power generator to the Operational Recovery of Separated Hydrogen and Heat Inquiry-2 (Oroshhi-2) nuclear fusion primary molten salt test loop constructed at the National Institute for Fusion Science and conduct a demonstration test of the power generation principle from the world’s first nuclear fusion simulated heat output. In this paper, we describe the results of a design study of the FLiNaK/CO2 intermediate heat exchanger and SCOT power generation system and related equipment that can be connected to the molten salt test loop. From the results of this study, it was concluded that the power generation principle verification test with 20-kW(electric)–class power generation with an efficiency of 20% is possible by the SCOT system connected to the FLiNaK test loop in Oroshhi-2 equipment via the intermediate heat exchanger.
