Review of the Crystal River Nuclear Generating Station Unit No. 3, emergency feedwater system reliability analysis

The purposes of this report are to review the Emergency Feedwater System Upgrade Reliability Analysis for the Crystal River Nuclear Generating Station Unit No. 3, and to provide an independent evaluation of the Emergency Feedwater System reliability. This report presents estimates of the probability that the Emergency Feedwater System will be unavailable given each of three different initiators: (1) loss of main feedwater with offsite power available, (2) loss of offsite power, (3) loss of all 4160 VAC power. The scope, methodology, and failure data are prescribed by NUREG-0611, Appendix III. 11 references, 5 tables.
