Appendix D Scenario Outline Form ES-D-1 Facility: ___Point Beach_____ Scenario No.: __1_____ Op-Test No.: 2011301 Examiners: ____________________________ Operators: _____________________________

Initial Conditions: _100% reactor power - EOL Turnover: Emergency diesel generator (G01) is OOS, motor-driven auxiliary feedwater pump (P38A) is OOS. The return to service time for both the G01 and P38A is approximately four hours from now. The plant is under a severe weather watch. G02 is aligned to 1A05 and 2A05 in accordance with OI-35A. IT 07G SW valve stroke time test is scheduled to be conducted immediately after shift turnover.

Facility: Point Beach Nuclear Station Scenario No.: 3 Op-Test No.: 2011301 Examiners: D. McNeil Operators:

R. Walton D. Reeser Initial Conditions: Unit 1 is at 23% reactor power, BOL, equilibrium xenon conditions following a reactor trip from full power five days ago due to a failure of the Unit 1 Voltage Regulator. Unit 2 is at 100% reactor power. Present clock time is real time. Normal shift complement with the exception of the 3rd SRO.

Turnover: G-01 EDG is out of service for annual maintenance. It was taken OOS 2 days ago, and is expected to be returned to service in 3 days. G-02 EDG is aligned to 4.16kV buses 1-A05 and 2-A05 IAW OI-35A. P-38B, Electric Auxiliary Feedwater Pump was declared inoperable 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> ago due to recirculation line cracks and has just been tagged out for repair. A severe thunderstorm watch is in effect for the next 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. The RCS is at normal operating pressure and temperature. Steam Generator water level is being controlled with the Main Feedwater Regulating valves in automatic on a single train of feedwater and condensate. OP-1C, "Low Power Operation to Normal Power Operation" is in progress. You are to continue with unit startup per OP-1C.

Event Malf. Event Event No. No. Type* Description 1 R Normal Up-Power 2 I Thot Instrument (TE-401A) Fails High Running CCW Pump Shaft Seizes w/Failure of Standby CCW 3 C Pump to Auto Start 4 I Controlling SG Pressure Channel (PT-478) Fails High 5 M Small RCS Leak in "A" RCS Loop Degrading to Large Break 6 M Large Break LOCA 7 I Failure of SI to Auto-Actuate 8 C Failure of Containment Accident Fan 1W-1A1 to Auto-Start 9 C Failure of 1SI-852A to Auto-Open
