Baseline Risk Index for Initiating Events (BRIIE) is an integrated industry-level initiating event performance indicator that is risk informed. BRIIE is a performance indicator that provides a mechanism for determining the risk significance of changes in performance, at both the individual initiating event level and at the integrated cornerstone of safety level. This paper describes the process to use BRIIE to evaluate the initiating events in Daya Bay NPP. We established two indexes for BRIIE, one is based on NRC baseline, the other is based on the plant specific PSA initiating events frequency. Both indexes of BRIIE are calculated in two tiers.
