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.

This paper introduces current issues, challenges, and future directions of nuclear thermal-hydraulic (T-H) safety research, viewed in close conjunction with new developments in advanced reactor systems and simulation tools and lessons learned from the Fukushima accident.
Two technical concerns are introduced to illustrate some of the limitations in our current understanding of important T-H phenomena that are very relevant to nuclear safety. The first is reflood heat transfer, which has been an important safety issue for a long time, and the second is the multidimensional T-H phenomena appearing in nuclear reactor systems, which have rather recently drawn significant attention in the nuclear community. These concerns are discussed by taking some recent research examples and emphasizing their critical relevance to nuclear reactor safety.
Then, some challenging issues for the advancement of nuclear T-H safety technologies are identified and briefly discussed in close conjunction with recent research efforts, and perspectives on advanced nuclear T-H safety research are presented.
