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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

There has been an ongoing search for more efficient power plant designs over the last few decades. For fossil-fueled power plants, this has resulted in the development of supercritical water Rankine steam cycles in the 1960s and most recently ultra-supercritical water power cycle systems. In addition, the use of supercritical fluids has been proposed for power cycles as part of the Generation IV (Gen-IV) advanced nuclear reactor designs, since these systems can also provide for higher thermal efficiency and reduced overall costs. For either of these power plant designs, both supercritical water and supercritical carbon dioxide have been considered as working fluids for either Rankine or Brayton cycle designs for a wide range of Gen-IV reactor designs, e.g., supercritical water reactor, high-temperature gas-cooled reactor, and liquid-metal-cooled reactor. In all of these designs, it has become quite apparent that research and development (R&D) investment in innovations in supercritical fluid thermal hydraulics and related materials issues is required to advance the state of the art in more efficient, cheaper, and safer nuclear power system technologies. One can view supercritical fluid transport phenomena as a base technology R&D need that requires more fundamental understanding in a number of areas. The Wisconsin Institute of Nuclear Systems at the University of Wisconsin-Madison has been investigating a range of key phenomena in supercritical fluids involving flow stability, critical flow phenomena, heat transfer enhancement and degradation, as well as materials corrosion issues. This paper summarizes our efforts in thermal hydraulics in order to provide a context for base technology R&D in supercritical fluids to advance Gen-IV systems.
