| 摘 要： | 三维离散纵标-蒙特卡罗（SN-MC）耦合方法结合了SN方法计算速度快和MC方法几何描述精确的优点，可以在较短的时间内完成堆腔辐射漏束辐射场计算.以秦山一期反应堆和CAP1400反应堆为研究对象，采用三维SN-MC耦合方法进行了堆腔漏束的计算，并和测量值以及其它方法的计算结果进行比较，验证SN-MC耦合方法理论模型和程序的正确性，为后续提高堆腔漏束计算精度和效率提供基础.

| Abstract: | By combining advantages of SN method (high calculational efficiency) and advantages of MC method (fine geometrical modelling), three-dimensional discrete ordinates-Monte Carlo method (3D SN-MC coupling method) is able to calculate cavity streaming dose rate in short time. SN-MC coupling method is applied on Qinshan No.1 reactor and CAP1400 reactor cavity streaming calculation. Results of SN-MC coupling method are compared with measurements and results of MCNP bootstrapping method. It shows that theoretical model and codes of 3D SN-MC coupling method are both correct. |
