List the sources of emergency makeup water to the Fuel Pool:
- Condensate service stations
- Demin water
- Firehose straight to Fuel Pool
- Filter demin backwash connection
- RHRSW via RHR
- Firewater via RHR
- Precoat pump
- RHR suction from Torus
List the five Fuel Pool cooling modes:
- Normal cooling/cleanup
- Max normal cooling
- Non-emergency core offload
- Emergency cooling
- Refueling well drain down
What is the Fuel Pool cooling rate (btu/hr) in the normal cooling mode?

5.6x10⁶ btu/hr in normal
What is the Fuel Pool cooling rate (btu/hr) in the emergency cooling mode?

20x10⁶ btu/hr
What pressure is the Fuel Pool Cooling pump suction trip?

6.5#
What are the Fuel Pool Cooling pump power supplies?
- FPCP 11 = MCC-133
- FPCP 12 = MCC-143
What is the name of the blue glowing effect in the fuel pool?

Cherenkov Effect
What are the assumptions for the Normal Refueling discharge heat load?
- 141 assemblies discharged every 18 months w/ average exposure of 25,000 MWD/MTU with 96 hours of cooling time
- Heat load per discharge batch is nominally 5.6x10⁶ bty/hr
- Heat load decays rapidly
What are the assumptions for the Emergency Cooling Full Core Discharge?
- Discharge required 30 days after last refueling and fills final 484 spaces in HDFSS
- Full core discharge completed 150 hrs after shutdown
- Heat load calculated is 19x10⁶ btu/hr
What fan is associated with the ventilation ducts on the Fuel Pool skimmer surge tanks?

V-EF-28 is the FP exhaust fan
What is the Fuel Pool temperature alarm setpoint, and where do they monitor temperature?
- 120F
- Monitored at suction of FPCP
What is the Fuel Pool cooling pump low discharge pressure setpoint?

50#
What is the Fuel Pool Filter/Demin high inlet temperature alarm setpoint?

100F
What are the Fuel Pool skimmer surge tank level alarm setpoints?
- 8 ft - high level alarm
- 4 ft - low level alarm
- 2 ft 6 in - FPCP trip
What is the Refuel Floor ventilation supply fan?

V-AH-4A/B
During refueling, what system is always running and adding water to the Fuel Pool system (with gates removed)? How much water is added?
- CRD cooling water flow
- Adds approximately 50gpm
What flowrate will start the Fuel Pool filter/demin holding pumps?

150 gpm
What is the primary power supply for the Fuel Pool filter/demin system?

MCC-141
What is the Fuel Pool heat exchanger outlet high temperature alarm?
A. 100F
- 120F is the Fuel Pool pump suction temp
- 140F is the filter/demin high temp
- 150F is a distractor
