ASME J of Nuclear Rad Sci 4(3), 031010 (May 16, 2018) (9 pages) Paper No: NERS-17-1143; doi: 10.1115/1.4039036 History: Received October 08, 2017; Revised January 10, 2018

Subchannel thermal-hydraulics program named CORe thermal-hydraulics (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. Test results show that the calculation efficiencies of linear systems occupy a large proportion of according serial computation. Based on the analysis, both programs' efficiencies are improved greatly through the proposed distributed-memory parallel strategy.
