摘要 离散纵标(又称SN)方法是反应堆压力容器快中子注量率计算中最常用的方法之一。计算机的飞速发展和三维离散纵标方法的不断完善,使得三维离散纵标法应用于工程设计成为可能。本文以某压水堆为研究对象,采用基于三维全堆芯中子学程序SCIENCE的计算结果,使用三维离散纵标方法程序计算了压力容器内表面快中子注量率三维分布,并分别与采用传统的一维、二维方法合成三维方法及蒙特卡洛方法得到的计算结果进行了比较,从而对三维离散纵标法在压水堆RPV快中子注量率计算中的应用进行了初步验证。 Discrete ordinates(SN) method is one of the most widely used method for reactor pressure vessel(RPV) design.As the fast development of computer CPU speed and memory capacity and consummation of three-dimensional discrete-ordinates method,it is mature for 3-D SN method to be used to engineering design for nuclear facilities.This work was done specifically for PWR model,with the results of 3-D core neutron transport calculation by 3-D core calculation,3-D RPV fast neutron flux distribution obtain by 3-D SN method were compared with gained by 1-D and 2-D SN method and the 3-D monte carlo(MC) method.In this paper,the application of three-dimensional SN method in calculating RPV fast neutron flux distribution for pressurized water reactor(PWR) is presented and discussed.
