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.

Many nuclear reactors are constructed of arrays of parallel channels. In order to carry out heat-transfer and flow-redistribution calculations for such arrays, proper boundary conditions must be assigned. These boundary conditions are not always obvious. In this paper, a method of formulating boundary conditions is discussed in which the stagnation streamline is used to define fictitious channel extensions upstream and downstream of the original parallel-channel configuration. This procedure is equivalent to defining a new parallel-channel configuration for which the boundary conditions are more clearly defined. A comparison of the calculated hydraulic parameters with the associated experimental results shows that the method is essentially correct.
