| 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 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. |
