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 heuristic search method for generation and optimization of pressurized water reactor (PWR) fuel reload configurations is developed and implemented in a research prototype. This is used to test the method on a sequence of typical PWR reload problems. Applying the method to a problem of reload with burnable poisons (BPs) helps avoid decoupling the fuel configuration problem from the reactivity control BP problem. Thus, better and physically transparent solutions are obtained. In another example, an attempt to achieve the flattest possible power distribution demonstrates the flexibility of the method. Finally, the potential of developing the method into a practical software tool for routine use by fuel-management engineers in industry is demonstrated.
