The Pilsen NDT Laboratory will use pulse thermography for testing

The Pilsen Nondestructive Testing Laboratory has put in place a thermovision inspection system that works on the principle of pulse thermography – it evaluates the behavior of the body when receiving thermal energy from flash and its re-radiation to the surrounding environment. Pulse thermography is a non-contact test method that is suitable for characterization of thin layers and coatings, enables quantization of material thicknesses, porosity or defect detection.

The Thermal Inspecting System will be used in the NDT laboratory to detect passage cracks or surface cracks, internal defects in material or corrosion in various structural materials such as metals or concrete. It also allows the assessment of the condition of protective coatings, for example on heat or radiation exposed technologies, the same system being used, among others, by the American Electric Power Research Institute (EPRI), for example, for checking the spent fuel pool walls.

The new facility extends the NDT Laboratory’s capabilities to an additional method of assessing the residual life of components of energy blocks and performing operational controls.
