A Safety Injection Signal has just occurred concurrent with an undervoltage condition on NB02. Prior to this event, the operating crew had just placed the "A" Spent Fuel Cooling Pump in service and aligned the system for makeup from the RWST to the Spent Fuel Pool. What describes the present status of the Spent Fuel Pool System? A. NE02 will re-energize NB02 and the shutdown sequencer will restart "A" Spent Fuel Pool Cooling pump.B. The load shed circuit deenergized B Spent Fuel Pool Cooling Pump.C. The Spent Fuel Pool heat exchanger CCW motor operated discharge valves are closed by the SIS.D. Both Spent Fuel Pool Cooling pump remain running throughout the event.

The Spent Fuel Pool Water Level is at 19 feet over the top of the irradiated fuel assemblies.Which of the following indicates the significance of, or basis for this level? A. Pursuant to 10 CFR 50.37a the radioactivity levels in liquid and gas effluents will be maintained in the event of the Design Basis Fuel Handling Accident.B. Radiation levels will increase on the manipulator crane over the refueling pool due to inadequate shielding.C. Iodine may not be adequately scrubbed from gas bubbles escaping from a damaged or leaking assembly.D. On a loss of offsite power there will be insufficient mass to prevent boiling prior to restoration of Spent Fuel Pool Cooling.

The plant is in Mode 5. B KA air compressor is tagged out for maintenance when an electrician inadvertantly de-energizes PA01 bus.What prevents draining the Spent Fuel Pool to the refueling canal in this condition? A. A semi-pneumatic seal replaced the original seal so an air source is unnecessary.B. Gate seals are inflated with nitrogen and isolated so loss of air will not affect them.C.
