If the OBE acceleration limits have been exceeded, perform a normal reactor shutdown per 101-3, Power Changes, and 101-4, Shutdown. ~ 3. Within 20 minutes of the seismic event, perform an inspection of the Control and Computer Rooms Humidification System (M29) for leakage. If the inspection cannot be made or leakage is detected or suspected, shutdown the M29 system per 501-M29. 4. The following plant parameters should be checked and evaluated to determine the extent and location of any plant damage: 9 a. Major plant variables 1) Control rod positions 2) Reactor power and water level 3) Feedwater and steam flows 4) Generator load 5) Condenser vacuum - 6) Turbine vibration and bearing temperatures b. Airborne, process, and area radiation monitors. c. Sump alarms and pump-out rates. ( d. Off-Gas flow rates. High flow rates indicate excessive condenser in-leakage.
