摘要: KYCORE程序是中国核动力研究设计院开发的径向MOC(特征线方法)与轴向SN耦合三维中子输运程序.KYCORE将二维MOC与一维SN通过角通量实现高精度耦合,并通过粗网有限差分实现快速收敛,是目前可工程化应用于三维中子输运计算中精度最高的方法之一.介绍了2D/1D计算与加速理论,并通过与蒙特卡罗程序的计算对比,数值验证了KYCORE三维中子计算的准确性与高效性.Abstract: KYCORE is a radial MOC and axial SN coupled neutron transport software developed by China Institute of Nu-clear Power.Its highly accurate coupling between 2D MOC and 1D SN is realized by angular flux,which is one of the most accu-rate methods applying to 3D neutron transport calculation by now.The calculation is accelerated by CMFD for engineering appli-cation.This article introduces the 2D/1D coupling and acceleration theory.The accuracy and efficiency of the KYCORE 3D neu-tron transport calculation are verified by comparison with the Monte Carlo program.
