Step 02: after the in-service inspection data management software is developed preliminarily, developers construct a local area network A to realize functional docking with an independent inspection plan database (namely, a local area network B) of the nuclear power plant. The software is tested and run on line in the local area network A, a user evaluates the software from dimensions such as safe, stable and convenient software running, accurate data and the like, and developers debug the software according to feedback to finally realize formal online running of the software.
And 03, carrying out authority distribution on each user by a system administrator according to service requirements, and checking in-service data management software for authorized users.
Step 04: and an authorized user logs in the in-service inspection data management software by using a personal account and a password, and basic data maintenance is carried out by using a technical information module, so that parameters and drawings of a pressure container in the nuclear power plant are obtained and stored. Namely, the technical parameters of the pressure container and the 2D drawing which are arranged in advance are input into a technical information module, and the technical parameters comprise: the method comprises the following steps of belonging power plants, units, systems, function positions, equipment names, equipment categories, room numbers, materials, sizes, wall thicknesses, temperatures, pressures, welding seam information, safety accessory information and the like.
After in-service inspection data management software and a nuclear power plant inspection plan database are prepared, the nuclear power plant in-service inspection data management and analysis method can be implemented, and the method specifically comprises the following steps:
step 1: and acquiring the current latest nuclear power plant inspection plan.
The method comprises the steps of realizing in-service inspection data management software, utilizing a system control module and a plan scheme module of the software to realize real-time butt joint of an inspection plan on a local area network A and an inspection plan database of a nuclear power plant on a local area network B, judging whether the inspection plan names on the local area network A and the local area network B are consistent, if the inspection plan name on the local area network B is different from that on the local area network A, transmitting a file from the local area network B to the local area network A, and realizing updating of the inspection plan of the nuclear power plant on the local area network A.
Step 2: and compiling an inspection technical scheme based on the acquired inspection plan of the nuclear power plant.
This step is implemented by the plan schema module of the in-service inspection data management software. And the new task notification is automatically generated by the new verification plan synchronized to the local area network A, and the authorized user is notified to compile the verification technical scheme based on the new task notification, and the authorized user carries out online compilation and verification validation of the verification technical scheme according to the new verification plan.
After the inspection technical scheme is compiled, according to the newly compiled inspection technical scheme, the field inspection personnel execute inspection and detection on the equipment to be inspected and make inspection and detection records. The inspection of the pressure vessel in the nuclear power plant includes macro inspection, ultrasonic inspection, penetration inspection, magnetic powder inspection, wall thickness inspection and the like.
And step 3: a sub-item inspection report is compiled based on inspection data obtained from inspecting equipment and pressure vessels in a nuclear power plant according to an inspection implementation solution.

This step is implemented by the data analysis module of the in-service inspection data management software. Specifically, after the report takes effect, the software judges whether the defect parameters in the macroscopic, ultrasonic, magnetic powder, permeability and other itemized reports are blank, if not, the software extracts all the defect parameters from the itemized inspection reports and generates a defect report, and then judges whether the common-mode defects exist in the same equipment in the same nuclear power plant based on the defect report. If the pressure vessel defect exists, calling a corresponding historical processing scheme to eliminate the pressure vessel defect; if not, a first type of notice is generated for feedback to the local area network B.
And 5: and judging whether the wall thickness of the pressure container has a tendency of thinning along with the service life according to the itemized inspection report and the historical data, if so, calculating the annual average thinning rate of the wall thickness of the pressure container, further calculating the age required for thinning the wall thickness of the pressure container to the unqualified limit value, generating a second type notice according to the calculated annual average thinning rate and the calculated age, and if not, generating a third type notice according to the judgment conclusion.
This step is implemented by the in-service inspection data management software using a data analysis module. Specifically, wall thickness data are extracted from a wall thickness detection report of the itemized inspection report, a minimum value is identified according to a natural value rule, and a corresponding value is extracted to form a minimum wall thickness report. And according to the historical minimum wall thickness report of the pressure container, namely, comparing the historical data of the wall thickness, judging whether the wall thickness of the pressure container has the trend of reducing along with the service life. If the pressure vessel has the thinning trend, the annual average thinning rate is calculated, the required age limit when the wall thickness of the pressure vessel is thinned to be unqualified is measured, and a second type notice is synchronously generated and fed back to the local area network B to inform a user of the residual service life of the pressure vessel. And if the thinning trend does not exist, generating a third type notice for feeding back to the local area network B.

When a new nuclear power plant inspection plan is generated, an authorized user can fully reserve the technology and resources according to the notice to ensure that the pressure container can be smoothly replaced or equivalently treated in the remaining service life.
And 7: and returning to the step 1. And (4) the planning scheme module on the local area network A carries out judgment and identification on the inspection plan newly compiled and generated in the step 6 on the local area network B, and after the relevant files are transmitted to the local area network A from the local area network B, the relevant work from the step 2 to the step 6 is continuously executed.
