| 摘 要： | 建立起锂球壳模型，用三个不同的聚变评价中子数据库--FENDL2.1、FENDL3.0和JEFF3.2分别进行了中子输运模拟，比较了三个数据库的模拟结果。再对水冷增殖包层分别建立一维中子学模型和三维中子学模型，进行中子输运模拟。分析模拟结果表明，选择FENDL3.0作为水冷增殖包层三维中子学模拟的数据库；水冷增殖包层一维中子学模拟优先考虑柱壳模型模拟；水冷氚增殖包层的三维中子学模拟所得氚增殖率TBR能满足氚自持要求；而且外包层的TBR贡献是主要的。

| Abstract: | The simulation results from the FENDL2.1, FENDL3.0 and JEFF3.2 with the Li sphere shell model were compared. Simulations of the water could breeder blanket are carried out with the neutronics 1D model and the 3D neutronics model, respectively. The results show: the FENDL3.0 is the selected data libraries for 3D neutronics simulation of blanket module; the cylinder shell model is the first consideration for 1D neutronics simulation of WCBB; the TBR of the 3D blanket neutronics model can satisfy the demand of tritium self-sustaining. The out board blanket makes major contribution to the TBR. |
