BOTH Feedwater Pumps TRIPPED.

The reactor automatically scrammed.

ONLY ONE Control Rod is at position 48.

ALL OTHER Control Rods are FULLY INSERTED.

HPCI initiation RAISED RPV Water Level from 110 inches.

HPCI was MANUALLY TRIPPED as RPV Water Level reached 210 inches.

Plant conditions are currently:

Reactor pressure 700 psig, rising at 10 psig per minute.

MSIVs are OPEN.

The OPERATING CRD Pump TRIPPED.

What is the expected RPV Water Level response over the next TEN MINUTES, and what action will be required to be directed?

Over the next TEN MINUTES, RPV Water Level will . . .

_____ A. RISE due to SWELL. It is required to direct operators to allow steam off to lower RPV Water Level BELOW 214 inches.

_____ B. LOWER due to SHRINK . It is required to direct operators to use HPCI to maintain RPV Water Level ABOVE 173.4 inches.

_____ C. LOWER due to SHRINK. It is required to direct operators to use ONLY RCIC to maintain RPV Water Level ABOVE 0 inches.

_____ D. RISE due to SWELL. It is required to direct operators to TERMINATE AND PREVENT Injection Systems to lower RPV Water Level BELOW 114 inches.

Correct Answer: A HPCI injected (100 inches x 200 gal per inch=) 20,000 gallons of cold CST water. As this water is heated, SWELL occurs. It is required to maintain RPV Water Level below Level 8 (214 inches). The SRO is required to direct operators to allow steaming to lower RPV Water Level. Shrink cannot occur because heatup and pressurization of saturated system is in progress with NO steam voids. ALL SRVs and TBVs are shut for the next ten minutes because Reactor Pressure will be below 800 psig.

Plausible Distractors:

B is plausible; identifies misconception about shrink and swell.

C is plausible; identifies misconception about shrink and swell. 0 inches is the MINIMUM for the ATWS RPV Water Level Control Band. ATWS is plausible because ONE Control Rod did not fully insert.

D is plausible; 114 inches is the MAXIMUM for the ATWS RPV Water Level Control Band.

ATWS is plausible because ONE Control Rod did not fully insert.
