Abstract
The problem of the concrete actual state estimation for geometric outer fence structures of localizing security system of reactor containment of Rivne NPP unit №3 is considered. The analysis of instrumental data of 2007 year is executed taking into account the provisions of the existing current standards. The technique of data processing and analysis taking into account the time factor influence on the strength characteristics of concrete is given. The „strength – ultrasound passing time” and „strength – diameter of impression” graduated dependencies are constructed, the class and strength characteristics of concrete for the time of instrumental examination in 2007 and for the time of structure building in 1970s are determined. On the basis of the analysis of the results, the depths of surface microcracks penetration in concrete are estimated, conclusions of research are formulated.
