Abstract

A review of the Reactor Oversight Process (ROP) and its characterization of human performance was performed by the Idaho National Engineering and Environmental Laboratory (INEEL) to describe the means by which the Nuclear Regulatory Commission (NRC) monitors, analyzes and feeds back information on human performance. Review of detailed human performance findings and trends observed in 37 operating events identified through the Accident Sequence Precursor (ASP) program served as the sample of operating experience. All events reviewed had a conditional core damage probability of LOE-5 or greater and indicated the influence of human performance. Reviews also considered Individual Plant Examinations (IPEs) and Augmented Inspection Team (AIT) reports. These reviews were then compared to ROP source materials. This included ROP source documents such as inspection manuals, SECY 007/7A, SECY 0053, Inspection Procedures, Inspection Reports, and Plant Information Matrices (PIMs). Supplemental Inspections, risk-informed plant information notebooks, and the significance determination process (SDP) for Operator Requalification Examination were also reviewed. Insights regarding the characterization of human performance in the ROP are presented.
