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.

As part of the emergency core cooling studies for the SNR-300 reactor, the transient thermohydraulic behavior of the reactor inlet plenum was investigated. Using a simplified and scaled-down model of the plenum and using sodium as the working fluid, thermal shock experiments were performed for different mass flow rates and initial temperature differences. The measured temperature distributions of the test section were compared with calculated results of a computer program. Satisfactory agreement between theoretical and experimental results was obtained only if the influence of superimposed free convection on forced convection heat transfer was taken into account. The heat transfer coefficients used were theoretical results calculated by the computer program CØFFCØ. The experimental results consolidated the theoretical heat transfer coefficients for turbulent combined free and forced convection for a modified Rayleigh number ranging from 4 × 105 to 6 × 106.
