Developing a Computerized Aging Management System for Concrete Structures in Finnish Nuclear Power Plants

摘要: Finland has four nuclear reactors units in two power plants. The first unit started operation 1977 and the early 1980's all were use. During last few years aging management of Nuclear Power Plant's (NPP) concrete structures grown an important issue because existing are reaching end their licensed operating lifetime (about 40 years). Therefore companies developing systems to avoid premature degradation NPP facilities be able extend lifetime. This paper is about development a computerized ageing system for plants structures. built upon central database implementation applications. It will assist personnel implement activities at different phases plant. provide systematic methods planning, surveillance, inspection, monitoring, condition assessment, maintenance repair
