Problems solved by technology

[0003] At present, the leakage rate calculation and test parameter monitoring technology during the domestic primary circuit hydrostatic test is to use the EXCEL table to edit the calculation formula for sampling calculation and monitoring. Selecting appropriate time data to enter into the EXCEL table for calculation, the disadvantage is that it is impossible to carry out real-time monitoring and calculation of the leakage rate of the primary circuit hydraulic test and real-time monitoring of key parameters related to the leakage rate, so it is not convenient to find leakage faults in time and correct them. The operating parameters of the test equipment should be adjusted in time; and the manual selection of data is not possible for automatic and batch calculations. It takes 20 minutes to input and complete a calculation. At the same time, the sampling calculation and monitoring cannot fully reflect the actual situation of the leakage rate. After a single calculation fails, it is necessary to repeat the selected data calculation, the calculation process is complicated, and the accuracy and accuracy are relatively low
