The real time data comparison was developed for the non-destructive inspection of the steam generator tubes in nuclear power plants. Each tube provides a safety barrier between the primary and secondary coolant circuits. Each steam generator contains several thousands of tubes whose structural integrity must be ensured through the lifetime of the plant. To this aim, Laborelec performs, at each outage, extensive non-destructive measurements. These measurements generate several Gigabytes of data that are the basis of a historical database. Although most of the analysis is performed automatically, human interaction is needed for the comparison between previous and current measurement data. In order to perform this comparison automatically, LABORELEC has selected optical CD's to store and delivers the historical data bank on mobile inspection platform. Each mobile unit is equipped with a CDjukebox linked with an analysis station. The jukebox can operate with 100 CD's, which allows to store all previously recorded data. Dedicated software allows the analysis process to pre-fetch the historical data and to compare it on-line with the fresh acquired NDT-data. The comparison relies on signal features that are evaluated with fuzzy algorithms.The main benefits are :
