【摘要】 以10MW球床式高温气冷堆(HTR-10)实际运行数据为基础,利用高温气冷堆物理分析程序VSOP,对HTR-10的实际过渡过程进行模拟计算。模拟的思路是精确跟踪堆芯的功率历史和燃料装卸历史;描述不同时刻堆芯内物质组成的空间分布;确定燃料循环的详细模拟方案;根据控制棒位置历史加入适当的等效控制毒物;根据实际的热工水力学初始条件做热工反馈计算。更多还原

【Abstract】 The simulation method of the running-in phase of the HTR-10,the 10MW pebble-bed high-temperature gas-cooled reactor,has been demonstrated in this paper,based on the operation data of the HTR-10 and using VSOP,the HTGR physics analysis program.The major idea of the simulation includes the precise tracing on the power history and the fuel loading-unloading history of the core,the description of the spatial distribution of the compositions within the core at different moments,the determination of the detail simulation scheme on the fuel cycling,the effective control poisons added into the model according to the history of the control rod position,and the thermo-hydraulic feedback calculations based on the real inlet thermal conditions.更多还原
