| 摘 要： | 对HTR-10初次临界的几何模型进行了对比和分析，运用基于蒙特卡罗方法的MCNP4B和TRIPOLI-4．3程序描述了高温气冷堆的包缀燃料颗粒在燃料球内的随机分布以及燃料球和石墨球在堆芯的随机混合分布应用TRIPOLI-4．3对HTR-10进行了初次临界物理计算，并且与已有的MCNP4B的计算结果进行了比较结果表明：基于蒙特卡罗方法的MCNP4B和TRIPOLI-4．3程序，采用适当的几何描述方式可以用手球床式高温气冷堆的初次临界堆芯物理计算．

| Abstract: | The present study compared and analyzed the geometry treatments used for 10 MW High Temperature Gas-Cooled Reactors(HTR-10) initial criticality calculation,and TRIPOLI-4.3 and MCNP4B codes based on Monte-Carlo method were employed to describe the random arrangement of Coated Fuel Par-ticles(CFPs) in the fuel pebbles and the random distribution of the fuel and dummy pebbles in the core.HTR-10 initial criticality was calculated with TRIPOLI-4.3 code and compared with the previous results from MCNP4B.The present study showed that Monte Carlo codes TRIPOLI-4.3 as well as MCNP4B could be used in the first criticality physics calculations for pebble bed High Temperature Gas-Cooled Reactors by adopting appropriate geometry modellings. |
