In-service inspections of thick walled concrete structures
Ageing management and renewal of the operating license of existing NPPs are at present the main problems of nuclear energy. For the ageing management of concrete structures the OECD-Nuclear Energy Agency, Committee on the Safety on Nuclear Installations defined as the first priority ISI techniques for reinforced concrete structures having thick sections and areas not directly accessible for inspections. In this paper is described the NRI Rez research and development programme in this field. Three ISI techniques were selected: Impact-Echo ultrasound and high frequency radar or betatron 7 MeV. In the period from 2004 to 2005 the mathematical studies of efficiency of Impact-Echo method for detecting of reinforcing bars, deep surface cracks and internal voids were done. In 2005 will be manufactured the 2 x 2 x 1 m concrete specimens with reinforcing bars, crack and holes which represent possible defects. Results of the solution will be used for qualification of ISI techniques.
