Streaming in Lattices

Part of the Advances in Nuclear Science and Technology book series (ANST, volume 15)


Pioneering work on the diffusion of neutrons through heterogeneous media was published by Behrens (1) in 1949, and thus, some of the methods that are used today to deal with neutron streaming processes already have been evolving for 30 years. In those 30 years, streaming computational techniques, jointly with a body of underlying theory, have been developed with great vigor. As one might expect, perhaps, this vigorous development has been somewhat chaotic. In the literature on neutron streaming, many authors have formulated many definitions of homogenized diffusion coefficients and interrelations among these coefficients so far have not been thoroughly explored. Not infrequently, in fact, definitions that seem to be totally different have turned out to be equivalent. Under such conditions, a coherent and complete review of streaming computational techniques of streaming computational techniques seems not yet feasible; and it is by no means our intention here to attempt such a review. Instead, we shall focus our attention on just a few areas in which current research has been particularly active. For the sake of coherence, many methods and some important problems will be passed over without comment. Since we shall be forced to omit so much, it seems appropriate, at this point, to tell the reader just how we have limited the scope of our discussions.
