Appendix D Scenario Outline Form ES-D-1 Facility: _Point Beach_____ 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__

accordance with OP 1C, Startup to Power Operations. 1P-2B, Charging Pump is OOS and isolated _

per OI 50, Charging Pump Isolation for pump repairs. 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. ____________________
