Abstract

During the last 30 years, EDF has acquired a thorough experience in modelling reliability and safety of nuclear power plants. Relying on this experience, R&D division decided to carry out reliability studies of electrical systems in order to optimise EDF´s electrical network asset management. But this type of system, usually with stand-by redundancies, is difficult to treat with classic reliability methods like fault-trees or reliability block diagrams. This paper presents a tool called OPALE, based on innovative methods developed by EDF R&D. A demonstration of OPALE is done on a complex electrical network with stand-by redundancies
