This report presents the results of the Phase 1 development of risk-based performance indicators (RBPIs) to potentially enhance the Reactor Oversight Process (ROP). SECY-99-007 recognized that improved performance indicators may be developed as part of the evolution of the ROP. RBPIs reflect changes in licensee performance that are logically related to risk and associated models. To the extent practical, the RBPIs identify declining performance before performance becomes unacceptable, without incorrectly identifying normal variations as degradations (i.e., avoid false-positive indications and false-negative indications). Phase 1 of the RBPI development includes performance indicators that are related to the initiating events cornerstone, mitigating systems cornerstone, and the containment portion of the barrier integrity cornerstone. The potential integration of RBPIs into the ROP would follow the change process described in IMC-0608, "Performance Indicator Program."
