CANDU형 원전 경년열화 감시시스템(Aging Monitor) 개발

As the operating time in nuclear power plants (NPPs) increases, the integrity of nuclear components may be continually degraded due to aging effects of systems, structures and components. Based on lots of aging database obtained from the operating plants and research results on the aging effects, the aging monitor (AM) was developed to monitor, manage and evaluate the aging phenomena systematically and effectively in NPPs. In this paper, the CANDU Aging Monitor for including 6 modules was introduced: (1) Aging Alarm/Coloring Monitor, (2) Aging Database, (3) Aging Document, (4) Real-time Integrity Monitor, (5) Surveillance and Inspection Management System, and (6) Continued Operation and Periodic Safety Review (PSR) Safety Evaluation.
