PARALLEL IMPLEMENTATION OF INTEGRAL TRANSPORT METHODS

The parallel implementation of three integral transport methods (colli sion probability, interface current, and current coupling collision pr obability) 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. Simila r success in the overall implementation was achieved only when larger geometrical domains were analyzed.
