Abstract
Concrete used for low-level radioactive waste disposal sites must be managed to satisfy the required quality for performance assurance and accountability after construction. However, it is not easy to ensure the quality of concrete due to environmental factors and human factors under construction. In Central Research Institute of Electric Power Industry, nondestructive inspection techniques has been studied and a nondestructive air-permeability tester called ”TCAPT” has been developed. In order to perform this test for concrete with large wall surface more efficiently.,combination of a wall-walking robot with the TCAPT is effective. We have been developing a concrete wall inspection robot by fusion of a wall-walking robot with the TCAPT. In this paper, we propose a new mechanism to increase the reliability of adhesion with validation of the eectiveness.
