MOC/SN coupled 3D neutron transport software KYCORE

KYCORE is a radial MOC and axial SN coupled neutron transport software developed by China Institute of Nuclear Power. Its highly accurate coupling between 2D MOC and 1D SN is realized by angular flux, which is one of the most accurate methods applying to 3D neutron transport calculation by now. The calculation is accelerated by CMFD for engineering application. This article introduces the 2D/1D coupling and acceleration theory. The accuracy and efficiency of the KYCORE 3D neutron transport calculation are verified by comparison with the Monte Carlo program.
