| 中文摘要: |
| 作为下一代能源的优先选择者，加速器驱动次临界系统ADS能够有效的利用铀和钍资源，并能够转化具有长期放射性的核废料，提高了核安全．文章主要是对快热耦合ADS次临界堆芯进行了描述，利用蒙特卡罗代码MCNP模拟计算一系列不同堆芯参数下的Keff值，MCNP程序中最重要的就是输入文件，输入文件各个参数设置的不同都可能对Keff值计算结果产生极大影响．在解决输入文件问题的过程中，根据实际经验对计算条件进行多组假设，并对不同参数条件下产生的结论进行比较，最终得到Keff值的最佳结果。 |
| 英文摘要: |
| As a prior option of the next generation of energy source, the Accelerator Driven Subcritical nuclear system (ADS) can use efficiently the uranium and thorium resource, transmute the high-level long-lived radioactive wastes and raise nuclear safety. The work presented in this article is focused on the description of the fast-thermal coupled ADS subcritical reactor core and the calculation of the values of K_(eff) using the Monte Carlo code MCNP under various parameters of the reactor core. The parameters of input files is the core of Monte Carlo code MCNP,which will greatly affect the result of K_(eff) calculation. And a group of assumptions derived from practical experience are used in settling the problem of input files. After comparing the result of different parameters, we get the agreeable result of K_(eff) value. |
