Use of CEDB for PSA

The Component Event Data Bank (CEDB) is a centralized bank collecting, at the European level, data describing the operational behaviour of components of Nuclear Power Plants (NPP's) operating in various European countries. It is one of the three event data banks of the European Reliability Data System (ERDS). The CEDB stores information on the operational history (operational times and/or number of demands of intervention in a year, failure-events reports) of components of NPP's well identified by their engineering and operation characteristics. The CEDB (as well as the whole of the ERDS) was conceived as a support to the analyst in his safety assessments for the design of a new NPP or the backfitting of an old one. (orig./HSCH)
