Establishment of a Data Management System to Administrate Inspection History

There are huge amount of results related to flaws detected by non-destructive tests, because the results have accumulated for about 40 years since Kori 1 started the commercial operation in 1978. However, the data are spread on plant attribute libraries, departments associated with inspections, etc. It is needed to administrate the data systematically, which have been being produced In order to resolve that problem, Central Research Institute of KHNP has developed an in-service inspection data management system to administrate the history data related to the in-service inspections of 23 nuclear power plants with the reports associated with pre and in-service inspections accumulated for 40 years. In this paper, the system is introduced briefly. The in-service inspection of nuclear power plants is a forensic examination and it is very important because it has an effect on the reliability of integrity of nuclear power plants. There are tremendous amount of data produced from the in-service inspection currently. They are issued as hard copy type reports. It is very hard to find the required data promptly from the hard copy type reports at an emergnecy situation. In order to resolve that problem, Central Research Institute of KHNP has developed an in-service inspection data management system to administrate the history data related to the in-service inspections. It is now to support the in-service inspection effectively. It is expected that the reliability of the in-service inspection for nuclear power plants would be improved because the system shows the examination history and results systemtically.
