Parallelization of Detailed Thermal-Hydraulic Analysis Program SPIRAL

Deguchi, Akira*; Ohshima, Hiroyuki

A detailed thermal-hydraulic analysis computer program SPIRAL is under development for the evaluation of local flow and temperature fields in wire-wrapped fuel pin bundles deformed by the influence of high burn-up, which are hard to reveal by experiment due to measurement difficulty. This report describes the parallelization of SPIRAL for improving applicability to larger numerical simulations. As the parallelization efficiency, approximately twelve times processing speed could be obtained by using 16 processor elements in larger scale simulations.
