Independent Review of Mitigating System Performance Indicator Reporting in the EPIX Database
- Idaho National Lab. (INL), Idaho Falls, ID (United States)
This report summarizes work done to verify the component, failure mode, and method of detection information provided in the Equipment Performance Information Exchange (EPIX) to support implementation of Mitigating Systems Performance Indices. This task is to select reports from EPIX and determine if their categorization as MSPI or non-MSPI failures is consistent with the development of unreliability baseline failure rates, and whether this significantly affects estimates of plant risk. This review is of all MSPI devices in EPIX that were reported as failures. The components include emergency generators; motor-driven, turbine-driven, and enginedriven pumps; and air and motor-operated valves. The date range for this report includes all MSPI device reported failures from 2003 to the most current EPIX data at the INL (up to the 3rd quarter 2008).
