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SNMC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.
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.
