摘　　要：国内某核电机组汽轮机采用了国内厂家自主设计的复合卧式汽水分离再热器,其设备结构与M310机组有较大差异,在一级再热器隔离后再投运的运行控制上也存在较大差异。为此分析了该核电机组一级再热器隔离后再投运时存在的问题,提出运行优化方案并成功运用。该方案在保证机组安全、系统安全和设备安全的前提下缩短了一级再热器隔离后的再投运时间,提升了机组经济效益,可供后续国内新建机组同类系统运行优化参考。The turbine of some nuclear power plant uses the compound horizontal MSR that designed independent.The equipment structure and the operation of the first stage is quite different from that of M310 unit,and at the same time,there is also a big difference in operation control after the first-stage reheater is isolated and put into operation.Therefore,the problems existing in the operation of the primary Reheater of the nuclear power unit after isolation are analyzed,and the operation optimization scheme is put forward and applied successfully.On the premise of ensuring the safety of the unit,system and equipment,the re operation time after the isolation of the primary reheater is shortened,and the economic benefit of the unit is improved.
