This report documents a common cause event database and updates an earlier version of a database that was published as EPRI report NP-3967 in June 1985. The purposes of this report are to provide more information on the original set of common cause events, to expand on both the number of events and the coverage of different component types, and to provide guidance in how to use the database to support applied risk and reliability evaluations such as the ongoing individual plant examination (IPE). Included in this report are descriptions and analyses of events that were found to be of potential importance in a common cause analysis, statistical information from which to estimate common cause failure probabilities, and examples of how the information can be used to support a plant-specific probabilistic risk assessment (PRA) or reliability evaluation, according to the PRA Procedures for Common Cause Analysis documented in NUREG/CR-4780. That procedures guide, which was developed under joint sponsorship of EPRI and the US Nuclear Regulatory Commission, was supported by EPRI research project RP2169-4.
