摘　　要：应用系统经济程序ＳＹＳＴＯＫ对大环径比脉冲聚变堆ＳＴＲ（ＳｌｅｎｄｅｒＴｏｋａｍａｋＲｅａｃｔｏｒ）概念设计进行了系统参数模拟，并对它的投资费用和电成本进行了估算。为便于ＳＴＲ设计参数和经济性的分析与评估，参考了美国的ＡＲＩＥＳ－Ⅱ和ＰＵＬＳＡＲ－Ⅱ聚变堆设计并与之进行了比较。采用电成本ＣＯＥ（ＣｏｓｔｏｆＥｌｅｃｔｒｉｃｉｔｙ）为目标函数，对ＳＴＲ系统参数优化进行了研究。对ＳＴＲ电厂的ＣＯＥ与石油电厂、液化天然气电厂、煤电厂及裂变堆电厂的ＣＯＥ进行了分析比较。ＳＴＲ型聚变堆的长脉冲和大聚变功率特性使其具有相对良好的经济性和现实可能性。For a pulsed slender tokamak fusion reactor (STR), the conceptual design of which had been completed by the Fusion Reactor Division of SWIP, the simulation of system parameters and estimation of cost and COE (cost of electricity) are performed using the system economic code SYSTOK. The results are compared with those for ARIES Ⅱ and PULSAR Ⅱ. Using COE as objective function, the optimization study for the STR power plant is performed.And the cost of electicity of the STR plant is compared with that of oil fired plant,LNG fired plant, coal fired plant and fission reactor plant. It concludes that the feature of longer burn time and larger fusion power gives STR a relatively better economic and practical possibility.
