Recent earthquakes in Gyeong-ju and Po-hang have raised concerns about the safety of nuclear power plant structures. In particular, there is a demand for a technique for detecting and evaluating the deterioration that occurs in the concrete which is inaccessible after curing. In this paper, we propose a method for evaluating the reliability of concrete detection equipment using ultrasound, as the ultrasonic tomography technique has been attracting much attention with the detection technique of the inside of concrete.
