The article describes the results of the application of the eddy current method for nondestructive testing of heat-exchange tubes at operating NPPs. Typically tubes are produced of copper-nickel alloys and stainless steel. For the purpose of examining tubes of different materials eddy current probes of different types were used in order to increase reliability and precision. In order to obtain information on real flaw dimensions tubes were cut and examined using metallography equipment.
