汽水分离再热器(以下简称MSR)是压水堆核电机组特有的大型重要设备,其构造和系统都比较复杂。大亚湾MSR的设计是在法国Stein Industrie公司专利的基础上融合了GEC以往设计南朝鲜650MW核电5、6机组MSR的经验,并经空气动力实验室的MSR模型试验验证,由GEC作总体设计的。其功能是把高压缸排汽的湿度去除,然后经二级再热至低压缸所需的工作温度,既提高了低压缸的效率又解决了湿蒸汽对低压缸的侵蚀,提高了机组长期安全运行的可靠性。MSR的主要参数如下:主蒸汽进口温度:169.5℃主蒸汽出口温度:265.1℃主蒸汽进口流量:604.7kg/s
Soda water separator reheater (hereinafter referred to as MSR) is a large PWR nuclear power plant unique large equipment, the structure and system are more complex. Daya Bay MSR is designed based on the patent of Stein Industrie of France, which integrates the GEC’s experience of designing MSR of 5,6 units of South Korea’s 650 MW nuclear power plants in the past and has been designed by GEC as a whole by the MSR model test of aerodynamic laboratory. Its function is to remove the humidity of the high-pressure cylinder exhaust steam and then reheated to the required working temperature of the low-pressure cylinder by the second-stage, which not only improves the efficiency of the low-pressure cylinder but also erodes the wet steam on the low-pressure cylinder and improves the long-term safety of the unit Operational reliability. The main parameters of MSR are as follows: Main steam inlet temperature: 169.5 ℃ Main steam outlet temperature: 265.1 ℃ Main steam inlet flow rate: 604.7kg / s
