Application of Parallel Processing to RELAP
Given a simulation problem, decomposition-coordination techniques can be used to enhance parallelism in order to speed-up the simulation. This paper describes the use of such techniques on a simplified reactor model. In particular, two decomposition-coordination techniques are applied to the fluid system of the model. The decomposition of the fluid system from the heat system, and further decomposition of the latter is also described.
With the eventual aim of investigating the possibility of speeding up the Nuclear code RELAP V, a discussion of the possible decomposition in RELAP V is also given in this paper.
