Appendix D Scenario Outline Form ES-D-1 Facility: SSES Scenario No.: IL0602A (SRO) Op-Test No.:

Examiners: Operators:

Initial Conditions: Unit 1 at 50% power EOL, Unit 2 in ,ade 4.

Turnover: Startup Bus 10 is currently suwlied from Startup Bus 20 with Tie Breaker OAlO502 closed The shift will be directed to restore the electric plant lineup to normal by transferrinq Startup Bus 10 to Startup Transformer I O . Followinu restoration of the electric plant lineup, the crew will continue with power ascension by pulling control rods and raise Dower 4 0 % . Standby Liquid Control Pump 1B is inoperable while maintenance investiqates a hiuh motor vibration.
