ENCLOSURE 1 OCONEE UNITS 1, 2 AND 3 OCONEE STANDBY SHUTDOWN FACILITY REQUEST FOR ADDITIONAL INFORMATION
- 1. It is our understanding that the individual steam line rupture area is 6.3 square feet. This is about 20 percent larger than was used in the analyzed event. Please confirm that the conclusions of the analyzed event will not change with the increased area, and provide a basis for this conclusion.
- 2. For the analyses, the RCS pumps are assumed to trip at the time the control rods drop. Please confirm that the conclusions of the analyzed event will not change if offsite power remains available to drive the RCS pumps. If the conclusions of the analyzed event change, please justify your assumption that a loss of off-site power occurs in conjunction with the steam line ruptures.
