Abstract
Risk-based safety evaluation of concrete structures that encompasses their planning, design, construction and maintenance is expected to become a strong imperative. This paper describes safety evaluation predicated on a risk-based approach in connection with scenario selection, focusing on concrete structures at low-level radioactive waste disposal facilities. This scenario selection, which is based on the safety evaluation method predicated on the risk-based approach established by the Nuclear Safety Commission in the year before the Great East Japan Earthquake, is believed to be applicable to the safety, reliability and maintenance management of general concrete structures based on a risk-based approach, an area in need of urgent study.
