Embodiment Construction
[0091] The present invention comprises the following steps in turn:
[0092] Step 1. Obtain the measurement data of series A and B;
[0093] The following parameters are obtained through A series of measurements:
[0094] -Number of main pumps currently in normal operation RCP-A ;
[0095] - Minimum core supercooling margin ΔT SAT-A ;
[0096] - Core minimum subcooling margin validity state SΔT SAT-A ;1 means valid, 0 means invalid;
[0097] -Uncertainty of core minimum subcooling margin ΣΔT SAT-A ;
[0098] - Reactor pressure vessel water level L VSL-A ;
[0099] - Reactor Pressure Vessel Water Level Validity Status SL VSL-A ;
[0100] The following parameters are obtained through B series measurement;
[0101] -Number of main pumps currently in normal operation RCP-B ;
[0102] - Minimum core supercooling margin ΔT SAT-B ;
[0103] - Core minimum subcooling margin validity state SΔT SAT-B ;1 means valid, 0 means invalid;
[0104] -Uncertainty of core minimum ...
