Appendix D Scenario Outline Form ES-D-1 Facility: Limerick Scenario No.: 1 Op-Test No.:

L Examiners: Operators:

Initial Conditions: 4% power, Reactor Startup in progress, "1B" EHC pump blocked for maintenance Turnover: A Reactor Startup is in progress with GP-2, Normal Plant Startup completed up to and including step 3.4.1 5. Reactor power is approximately 4%. RClC is operating for ST-6-049-230-1, RClC Pump Valve and Flow Test, and RT-6-049-701-1 (step 4.4.30) should be completed within the next hour. !'I B EHC pump is blocked for maintenance, and will be out of service until a new pressure compensator arrives tomorrow. The bypass valve jack is being used to ensure partial bypass valve opening for feedwater stability per GP-2 step 3.3.20.4. The crew must continue power ascension to achieve 4 bypass valves open in preparation for main turbine startup. Control Rod movement is per the Control Rod Move Sheets, with Sequence Step Number 14, Rod Group 8, Control Rod 26-43 the next rod to withdraw (12-48).
