摘要：

根据DEMO情形下的堆芯和包层设计参数，基于包层产氚及热工的温度控制要求，研究了一种适合PWR水冷包层设计的氚增殖率(TBR)优化方法。利用中子学及有限元方法，建立了包层2维分析模型，计算了包层能量增益因子，并基于该因子计算了包层的总能量沉积。研究了包层结构参数变化时局部TBR的分布特点。重点基于温控方法研究了包层结构参数的变化与TBR之间的内在联系，获得了包层局部TBR达到最佳值的结构参数理论参考值。

Abstract:

Based on the DEMO case, a Tritium breeding rate (TBR) optimization method used in the design of the PWR water-cooled blanket concerning the temperature requirement of tritium production and thermal was presented. Two-dimensional blanket models were set up for the neutronics and thermal hydraulics calculations. As the basis of this research, the blanket neutron heat sink was primarily calculated using the blanket energy multiplication factor. Exploring the variation trend of TBR with the changing of blanket structural parameters based on temperature control mechanism was focused. At last, the optimized value of the blanket structural parameters was proposed.
