Resumo
A methodology to perform the integrity assessment of research reactors nuclear fuels cladding, such as those installed in the IPR-R1 (TRIGA) using eddy current nondestructive electromagnetic inspection method is presented. This methodology is constituted by the development of calibration reference standards, specific for this type of fuel; the development of customised test probes; the recommendations for the inspection equipment calibration; the construction of voltage based evaluation curves and the inspection procedures developed for the characterisation of the detected flaws. The operational performances of the developed resources, as well as the special operating characteristics of the test probes, such as underwater operation, were experimentally demonstrated. The practical applicability and the efficacy of the developed methodology were verified experimentally in non radioactive environment.
