摘　　要：采用离散坐标DOT3.5程序计算了秦山核电二期工程反应堆主屏蔽的中子和γ射线通量密度分布、剂量率和释热率,并用中子通量密度综合方法由一维和二维计算结果得到了空间任意点的三维中子通量密度,确定了压力容器内表面的快中子注量。其计算结果均小于设计限值,符合设计要求。The flux distribution, dose rate and heating rate of the primary shield were calculated with DOT3.5 discrete ordinates code in this paper. In order to determine the fast neutron fluence (E>1.0MeV) at the inner surface of the pressure vessel, 3-D flux at arbitrary points in space was obtained by synthesis from 2-D and 1-D calculation results. These values are lower than the design limit and satisfy the design requirements.
