Parallel Implementation of Integral Transport Methods

The parallel implementation of three integral transport methods (collision probability, interface current, and current coupling collision probability) for nuclear reactor lattice calculations in two dimensions was completed. A description of this work and performance on the CM-2 and CM-5 platforms are presented here along with comparisons with the serial versions of the methods. For all three methods, the probability calculations proved to be optimal for parallel implementation. Similar success in the overall implementation was achieved only when larger geometrical domains were analyzed.
