EXAMINATION 2002 NRC SRO Exam 95 ID: Q #95 SRO Points: 1.00 The following post LOCA conditions are present:
- All Rods in.
- The only operable ECCS pump is 1B Core Spray.
- Reactor pressure is 275 psig and slowly lowering.
- Reactor level is being maintained at -150 inches by:
- 2 Condensate/Condensate Booster pumps with a combined flow of 0.5 MLBM/hr.
- 1B Core Spray pump with a flow of 4600 GPM.
- Hotwell level is being maintained by Standby Coolant injection.
- All Torus water level indication has failed, however LI1-1640-21 "Primary Containment Water Level indicates 16.75 feet and rising.
What is the next required action and why?
A. Secure all operating injection pumps because adequate core cooling is assured.
B. Initiate SBLC to raise reactor water level above the top of active fuel.
C. Secure the condensate pumps because adequate core cooling is assured.
D. Start both remaining condensate pumps to raise reactor water level above the top of active fuel.
96 ID: Q #96 SRO Points: 1.00 Torus level is lowering as indicated on the narrow range torus level indication.
Which of the following list the HIGHEST Torus level during operation in Mode 1 which would require entering a Tech Spec LCO and why?
A. -1" due to excessive suppression pool TEMPERATURE during a DBA LOCA.
B. -1" due to excessive suppression pool SWELL LOADS during a DBA LOCA.
C. -3" due to excessive suppression pool TEMPERATURE during a DBA LOCA.
D. -3" due to excessive suppression pool SWELL LOADS during a DBA LOCA.
