Developments in mechanised ultrasonic inspection and qualification of NDE

Reliability of non-destructive testing results has a direct influence on structural integrity assessment and safety of the inspected structures, e.g., NPP primary circuit pressure boundaries. Advanced technology together with highly skilled and experienced personnel is required. One of the current trends is automation. Mechanised equipment can replace tedious manual work in positioning and moving of the transducers. Large areas can be scanned, analysed and numerically documented for direct comparison of eventual later repeated inspections. Another major trend is qualification, which aims to ensure that the inspection results are correct and fit for the purpose. The suitability and proper operation of equipment, methods and personnel, i.e. the whole chain, shall be proven. This presentation summarises the advances in automation and qualification of non-destructive inspection during the second project year. Monitoring of material degradation was included in the studied topics and will also be shortly described
