Fault Mechanism Analysis of Single Loop Flow Deviation in PWR Nuclear Power Plants

The 3rd Ring Rd PWR repeated some conditions such as single loop flow deviation in power operation, by the qualitative analysis of the possibility and rationality of fault mechanism, and combined with the similar foreign units experience feedback. The author concluded that the single loop flow deviation mostly is caused by the measurement factors, and nuclear power stations can carry out the fault analysis and confirmed by test and measurement data during the unit overhaul.
