Embodiment 1
[0074] An embodiment of the present invention provides a method for calculating and evaluating the containment leakage rate of a nuclear power plant, such as figure 1 As shown, the method includes:
[0075] S1. Obtain the Type A assessment uncertainty of the containment leakage rate calculation;
[0076] S2. According to the real-time measurement data of the sensors in the containment, obtain the B-type evaluation uncertainty for the calculation of the containment leakage rate;
[0077] S3. Combining the Type A assessment uncertainty and the Type B assessment uncertainty into a containment leak rate uncertainty, so as to evaluate the calculation of the containment leak rate according to the containment leak rate uncertainty.
[0078] It should be noted that during the operation of the unit, the containment leakage rate of the nuclear power plant needs to be monitored in real time to monitor the change of containment sealing, and the monitoring of the containment leakage rate ...
