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.

The positive coolant coefficient of reactivity characteristic of a large, economic, heavy-water-moderated, organic-cooled reactor (HWOCR) may make the power coefficient slightly positive. Therefore, the inherent reactor response characteristic of a positive power coefficient was studied dynamically to determine if a practical controller and shutdown system could be designed. Reactivity, coolant flow, and coolant inlet temperature perturbations were studied in controlled and uncontrolled situations. It is concluded that with a small positive power coefficient this reactor can be stably controlled with a simple on-off dead band controller and that a relatively unsophisticated shutdown system will prevent damage under severe transient conditions even in the case of a failure of the automatic controller.
