Development of deterministic neutronics analysis code GenesisRPC for general purpose, 2; Application to neutronics-thermal hydraulics coupling calculations

Liong, C.*; Yamamoto, Akio*; Endo, Tomohiro*; Tada, Kenichi

The purpose of this study is to apply neutronics thermal-hydraulics coupling scheme between the three-dimensional heterogeneous neutronics analysis code GenesisRPC and the JAEA-developed subchannel analysis code ACE-3D. As a test case, a simplified BWR assembly is used to perform the coupled simulation. The three-dimensional pin-by-pin power, pin-by-pin subchannel-wise coolant temperature, and void distributions were calculated.
