中文摘要：

在聚变裂变混合堆大、小半径分别不变情况下，通过优化聚变裂变混合堆中心螺管尺寸，用聚变系统分析程序对紧凑型聚变裂变混合堆的参数进行了优化分析，给出了紧凑型聚变裂变混合堆的最佳设计点。利用TSC平衡演化程序以该设计点为基础进行了放电模拟研究，结果表明该堆具有良好的经济优势及可行性。

英文摘要：

Under the conditions of constant major-radius and minor-radius, an optimal analysis for the parameters of the compact fusion-fission hybrid reactor, including the size of the center solenoid, has been made by using the fusion system analysis code, and the final optimal design point has been found out. Based on this design point, the discharge simulation of the reactor is performed with the tokamak simulation code （TSC）, and the modeling results show that the reactor is more economic and feasible.
