Scenario ONE - Turnover Information The Plant is at 100% power, MOL. P-8B, Auxiliary Feedwater Pump, is out of service for a bearing inspection (LCO 3.7.5.A.1 - 72 hrs.) It is expected to be 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> before bearing inspection is completed.
Shift orders are to alternate operating Service Water pumps (Start P-7B and stop P-7C and place it in STDBY): inform CRS to direct BOP to perform this task. Once this is complete, a power reduction to approximately 90% at 6% per hour is ordered in preparation for maintenance on Heater Drain Pump P-10A.

ESDE/LOOP//Failure of D/G 1-1 to auto start/ Loss of AFW Time Position Applicant's Actions or Behavior Isolates B S/G per EOP Supplement 18 (attached)
Isolation from inside the Control Room:
(CRITICAL TASK PL-000 209 05 01: The MSLB analysis assumes operators terminate auxiliary feedwater flow within thirty minutes.
Isolating the affected steam generator limits the addition of energy that is added into containment for which containment spray and containment air cooling have to cope, and to a lesser extent prevents the accident from exceeding the flood plain analysis. The time frame for isolating the affected steam generator is reasonable. Operators have steps in both EOP-1.0, Standard Post Trip Actions, and EOP-6.0, Main Steam Line Break to isolate auxiliary feedwater to the most affected steam generator. The only things that might prevent operators from meeting this time requirement are problems with the automatic actuation of SIAS/CIAS or small steam leaks that make determining the most affected steam generator difficult. Since the MSLB is a large steam BOP leak and the analysis doesnt include an active failure on SIAS or CIAS it is likely that operators would isolate water to the affected steam generator well within 30 minutes.)
