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.

Parallelization of the Porsching algorithm for the numerical integration of hydraulic network conservation equations is described, and a theoretical analysis of the performance of the parallelized algorithm on a MIMD-type parallel computer is given. It is shown that good speedup and efficiency of parallel processing can be achieved by using a quasi-MIMD mode of operation employing (a) a master/slave configuration of processors, (b) message passing for data communication, (c) global synchronization of all processors before data communication, (d) a simple time-shared bus with data broadcast facility as the interconnection network, and (e) distributed communication memories for data communication.
