中文摘要：

基于离散纵标和蒙特卡罗方法开发了三维离散纵标-蒙特卡罗耦合系统 TDOM INO ，其耦合形式灵活，可根据需要选择不同坐标系下的耦合方式进行计算分析。利用美国橡树岭国家实验室提供的HBR-2基准题，采用 TDOM INO分别建立了直角坐标系和圆柱坐标系下的耦合模型进行验证计算，给出了反应堆辐照监督管处6种典型核素比活度的计算结果，与基准报告中提供的实验测量值和DORT、MCNP、TORT等程序计算结果相比，TDOMINO具有较好的计算精度，可用于解决复杂屏蔽计算问题。

英文摘要：

On the basis of discrete ordinates and Monte Carlo methods ,the 3D discrete ordinates and Monte Carlo coupled system TDOMINO was developed . The ways of coupling were flexible since different coordinates can be selected for various coupled analyses .The validation of the coupled system TDOMINIO was completed with the HBR-2 benchmark provided by Oak Ridge National Laboratory . T he coupled models were established in Cartesian and cylindrical coordinate systems , respectively . The specific activities for the six dosimeters in the surveillance capsule were calculated .The comparison between the experimental measurements and the calculation results from DORT ,MCNP and TORT codes provided by the benchmark report demonstrates that TDOMINO has good accuracy and is suitable to solve the complex radiation shieldingcalculation problems .
