Scenario No.: _2___________
Op-Test No.: _2017____
Examiners: ___________________________ Operators:
Initial Conditions: _Unit 1 is in OP 1C, Startup to Power Operation, at approximately 29% post _
chemistry hold coming out of a forced outage. Chemistry has requested a bump of Main Feed and _
Condensate pumps for iron flushing in accordance with Step 5.31. 1W-3B, Control Rod Shroud Fan _
is OOS due to imminent motor failure. 1PT-950, Loop B Containment Pressure has been removed _
from service. Repairs are expected to be complete during the upcoming refueling outage.__________
Turnover: Start 1P-28B, SGFP and 1P-25B, Condensate Pump then secure 1P-28B SGFP, and _
1P-25B Condensate Pump after 5 minutes for iron flushing. Raise power to 50%. ________________

Scenario No.: _3___________
Op-Test No.: _2017____
Examiners: ___________________________ Operators:
Initial Conditions: _Unit 1 was lowered to approximately 75% at the request of MISO/ATC due to grid stability issues. Grid stability has been restored and the unit is ready to be returned to full power in__
