AP1000 Safety Analysis Report

*NRC Staff comments on AP1000 (CDF 5x10-7 events/year)

“the most significant improvement to the design is the use of safety systems that employ passive means”“the low CDF and

risk for the AP1000 plant reflect Westinghouse’s efforts to systematically minimize the effect of initiators/sequences that have been important contributors in previous PWRs”
