| 摘 要： | 用蒙特卡洛中子输运程序(MCNPX)对中国聚变工程实验CFETR超导磁体进行中子学输运计算，利用欧洲活化计算程序FISPACT对其进行活化计算分析，针对计算结果重点分析了磁体系统的中子学剂量分布以及活化情况。计算结果表明，中子能量通量最大处出现在聚变堆内侧线圈处，为3.97×1014 MeV•m–2，在该条件下超导线圈可以满足设计要求。停机后磁体组件的活度为3.33×1010Bq•kg–1，停机10年后下降2个数量级达到6.14×108Bq•kg–1。研究结果验证了所使用的CFETR 3维模型满足初步设计条件。 |

| Abstract: | The Monte Carlo neutron transport code (MCNPX) is used to carry on the neutronics calculation for CFETR magnet system, and its activation analysis is performed by FISPACT, a European activation calculation code, besides. The calculated results show that the max neutron energy flux is 3.97×1014MeV•m–2, which meets the design requirements of the superconducting coil under this condition. The activity of magnet assembly is 3.33×1010Bq•kg–1 when reactor is shut down, and after 10-year shut down, the activity reaches 6.14×108Bq•kg–1, which decreases two order of magnitude. Conclusively, the CFETR 3D model meets the preliminary design requirements and can provide some data support for the construction of CFETR. |
