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.

A proposed model for low-pressure subcooled boiling flow is incorporated into the RELAP5 reactor safety code to enhance its performance to predict the occurrence of the Ledinegg-type instability. The modified code is validated against experimental data. A marked improvement in the predictive performance is obtained. Although the results are encouraging, discrepancies between the modified code's predictions and the experiments are observed, particularly regarding the influence of subcooling on the flow instability.
