The civil structures of nuclear plants need to meet the most strict criteria in terms of safety and reliability not only during their design and construction, but during the duration of their life cycle. Regarding the specifics of nuclear plant operation the inspections of the said structures need to be fully non-destructive and visual inspection is the method mostly used. In rare occasions it is possible to obtain a material sample in the form of drilled powder or small diameter core. In this paper, an example of analysis of such material sample is given, showing the amount of information describing the structural material that can be obtained using state-of-the art analytical methods - Xray diffraction (XRD), X-ray fluorescence (XRF) and thermic analysis (TG/DTA). The paper shows results for regular structural concrete and special concrete with enhanced capability of shielding ionizing radiation.
