Title: System Study: Emergency Power System 1998–2012

This report presents an unreliability evaluation of the emergency power system (EPS) at 104 U.S. commercial nuclear power plants. Demand, run hours, and failure data from fiscal year 1998 through 2012 for selected components were obtained from the Equipment Performance and Information Exchange (EPIX). The unreliability results are trended for the most recent 10 year period while yearly estimates for system unreliability are provided for the entire active period. A statistically significant increasing trend was identified for unreliability (8 hour model) as a function of fiscal year. No statistically significant decreasing trend was identified in the EPS results.
