Following a reactor trip, a failure in Yellow Train SSPS causes Yellow Train P-12 steam dump solenoids to deenergize.What affect, if any, does this failure have on stabilizing RCS Tavg? A. Only the cooldown valves will operate, it will take longer to reach no-load Tavg.B. No steam dump valves will operate, S/G ARVs will control above no-load Tavg.C. The cooldown valves will not operate steam dump, valves will control at no-load Tavg.D. There is no impact, a single failure will not prevent steam dump valves from operating.

When transferring Steam Dumps from Tavg Mode to Steam Pressure Mode, the Reactor Operator failed to verify Steam Dump Demand Indication (AB-UI-500) and Steam Header Pressure Controller (AB-PK-507) were matched. When the Mode selector was shifted:* AB-PK-507 indicated 20%* AB-UI-500 indicated 5% What was Steam Dump System response when Steam Pressure Mode was selected? A. All Steam Dump Valves opened and modulated to 20% on the cooldown valves.B. All Steam Dump Valves opened and closed at 5500F.C. Group One Steam Dump Valves modulated closed.D. Group One Steam Dump Valves modulated open.
