福清5、6号机组反应堆冷却剂回路温度计变化对调试试验影响分析

Analysis on the Influence of the Change of Reactor Coolant Circuit Thermometer on the Commissioning Tests of Fuqing No.5 and No.6 Units

福清核电5、6号机组作为全球华龙一号机组首堆工程,针对反应堆冷却剂回路温度计设计有较大变化,去除了M310机型的测温旁路的方式测量一回路温度,改进为直接安装在一回路主管道上的方式直接测量。这种温度测量方式的改进,会对调试工作带来一定的影响。

Fuqing NPP Unit 5 and Unit 5 are the first reactor of Hualong Unit 1 in the world.There is a great change in the design of the reactor coolant circuit thermometer.The temperature of the primary circuit of the M310 is removed and the temperature of the primary circuit is measured.For direct installation in the main loop on the way a direct measurement.This improvement in temperature measurement will have a certain impact on the commissioning work.
