Establishment of Reliability Data for Power Plant Components by Means of an Information System

The increasing importance of safety and availability of power plant units demands more detailed and proven reliability data for plant components than operational experience could provide till now. In the Federal Republic of Germany an extensive collection of field data from a conventional power plant has been compiled since 1972. The authors give a survey on the information system processing these field data, in order to establish empirically tested reliability data for plant components.
