Abstract

Sub-channel thermal-hydraulics program named CORTH and assembly lattice calculation program named KYLIN2 have been developed in Nuclear Power Institute of China (NPIC). For the sake of promoting the efficiencies of these programs and achieving the better description on fined parameters of reactor, programs' linear systems and details are interpreted and parallelized. The experimental results show that calculation efficiencies of them occupy a large proportion of the serial computation. Based on the analysis, both programs' efficiencies are improved greatly through the proposed distributed-memory parallel strategy.
