摘　　要：针对华龙一号(HPR1000)核电机组运行图在特定工况下区域狭窄等问题。本文从提高余热排出系统(RHR)接入压力、降低主泵的启泵压力下限、扩大稳压器波动管两端允许的温差、降低反应堆冷却剂的过冷度限值等方面入手,对运行图进行了优化分析和研究,提出了HPR1000核电机组运行图的优化方案,优化前后对比分析表明,优化后的运行图的允许运行范围更宽、运行效率提高且运行可靠性增强。Aiming at the narrow area of the operating diagram of HPR1000 nuclear power unit under specific conditions,this paper makes an optimization analysis and research on the operating diagram from the aspects of increasing the operating pressure of the residual heat removal(RHR)system,lowering the lower limit of the start-up pressure of reactor coolant pump,enlarging the allowable temperature difference between the two ends of the pressurizer surge line,and lowering the limit of the sub-cooling of the reactor coolant.And then,an optimized operating diagram for HPR1000 is proposed.The comparative analysis before and after optimization shows that the optimized operating diagram has a wider allowable operation range,improved operation efficiency and enhanced operation reliability.
