A Steam Generator Tube Rupture has occurred. The plant is currently in MODE 5, and the crew is preparing to commence cleaning up the secondary plant.What is one of the three methods allowed to be used for this cleanup operation?

With the plant initially at 100% power, a load reject occurs, arming and opening the condenser steam dump valves. Which component associated with the Main Condensate System is specifically designed to aid the Main Condenser in handling the increased energy input due to the load reject?

The inlet isolation valve (3FWS-V986) to the feed system long recycle valve, (3FWS-HV43) is normally shut to prevent which of the following from occurring?

The plant is initially operating at 100% power with the "A" and "B" Main Condensate Pumps running when the following sequence of events occurs: 1. The COND PP AUTO TRIP/OVERCURRENT annunciator comes in on MB6A. 2. The BOP operator reports that the "A" Main Condensate Pump has tripped. How will the "C" Condensate Pump respond to this event, and what actions are the operators required to take?

While walking down the main boards, the BOP Operator observes the Condenser De-Superheating Spray Valve (3CNM-PV99), indicates OPEN at MB6. What condition could be the cause of this valve being open?

Plant efficiency is increased by preheating of the secondary water supplied to the Steam Generators. Which of the following items associated with the Main Condensate system performs this preheating function?

The plant is at 100% power. What condition could result in damage to the Turbine Driven Main Feedpump (TDMFP) seals?

What is the designed seal water header pressure supplied from CNM-PCV34 and CNM-PCV106?

The plant is at 100% power with all systems in automatic control. a. Approximately what percentage of the total flow supplied to the suction of the Main Feed Pumps is being supplied directly from the 2 operating Main Condensate Pumps? b. What is the expected discharge pressure of the Condensate Pump

A Steam Generator Tube Rupture has occurred, and current conditions are as follows: • The plant is in MODE 5. • A vacuum has been maintained in the Main Condenser. • Main Condenser hotwell level is normal. • The crew is preparing to commence cleaning up the secondary plant. What method is available for this cleanup operation?

The Condensate System has been placed in service on SHORT RECYCLE. Through what components, if any, will the water being discharged from the running Condensate Pump flow through prior to returning to the Main Condenser?

The plant is at 100% power with all systems in automatic control Approximately what percentage of the total condensate flow supplied to the suction of the Main Feed Pumps is being supplied directly from the 2 operating Main Condensate Pumps?

With the plant operating at 100% power, a HOTWELL SODIUM HI Annunciator is received in the Control Room. What is the most likely source of the sodium; and what is the major concern with sodium in the hotwell?

With the plant at 100% power, the following sequence of events occurs: 1. One of the running Main Condensate pumps trips. 2. The BOP operator attempts to start the standby Condensate Pump, but it does NOT start. 3. The BOP operator reports Main Feed Pump suction and discharge pressures are decreasing. What effect will this have on the Main Feedwater System?
