The Hualong No. 1 monitoring system developed by CNNC has passed acceptance to fill the domestic gap

Recently, the LBB leakage monitoring system of the main pipeline and fluctuation pipe of the Hualong No.
1 overseas first reactor unit, independently developed and manufactured by CNNC China Nuclear Power Research and Design Institute, passed the factory acceptance
.
The technical indicators of the system have reached the international advanced level, filling the domestic gap and providing strong support
for China's nuclear power "going global".

It is reported that the main pipeline and the fluctuation pipe LBB leakage monitoring system is the "three new equipment" of Hualong No.
1, through online monitoring of the sealing performance of the main pipeline and the fluctuation pipe of the reactor primary circuit, timely detection of the coolant leakage of the main pipeline and the fluctuation tube, effectively avoid the impact of nuclear radiation caused by the leakage of radioactive medium in the reactor primary circuit system, avoid nuclear safety accidents in nuclear power plants, play an important role in improving the safety of nuclear power plants, and also provide strong technical support for nuclear power plant leakage troubleshooting and maintenance
