Appendix D Scenario Outline Form ES-D-1 Facility: PINGP Units 1 and 2 Scenario No.: 2 Op-Test No.: 2012301 Examiners: D. McNeil Operators:
M. Bielby :
D. Reeser Initial Conditions: Unit 1 @ ~ 225 MWe BOL, Plant Startup in Progress. Unit 2 @ 100% power, MOL Equilibrium Xenon. Repairs and testing complete on 12 MFW pump. 2nd Condensate pump is in service.
Turnover: Power is to be reduced < MWe to facilitate a common cause evaluation of the 11 MFP.
Crew will brief power reduction and MFP swapping prior to entering the simulator. Maintain Unit 2 @
100% power. Equipment OOS, Nothing abnormal, only equipment related to plant specific issues.
