Nuclear power plants are duty to certify their security for renewal of operating license. Security can be significantly affected by defects of ageing reinforced concrete structures. Advanced Impact-Echo method seams to be very hopeful to do in-service inspections such structures. Just these in-service inspections are included in the first priority group of specific technical issues according to the recommendations of OECD-Nuclear Energy Agency, Commission on Safety of Nuclear Installation in the field of ageing management. This paper is a part of extensive project and continues a number of foreign papers about Impact-Echo method by Pe ínka, Morávka, Vold ich (2004–07), and some papers in Czech as well. It will bring a method description and main result survey of numerical modeling of detection of grouted (repaired) voids in massive concrete structures. Cavities are filled by grouting polyurethan compound CarboPur WF. We try to find out if it would be possible to confirm by ImpactEcho method, whether the injected cavities were fulfilled completely. Experimental verification of these numerical predictions on real scale (1:1) specimens in NRI ež will be follow.
