List the sources of emergency makeup water to the Fuel Pool:
Condensate service stations
Firehose straight to Fuel Pool
Filter demin backwash connection
RHRSW via RHR
Firewater via RHR
RHR suction from Torus
List the five Fuel Pool cooling modes:
Max normal cooling
Non-emergency core offload
Refueling well drain down
What is the Fuel Pool cooling rate (btu/hr) in the normal cooling mode?
btu/hr in normal
What is the Fuel Pool cooling rate (btu/hr) in the emergency cooling mode?
What pressure is the Fuel Pool Cooling pump suction trip?
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?
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 5.6x10
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 19x10
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?
Monitored at suction of FPCP
What is the Fuel Pool cooling pump low discharge pressure setpoint?
What is the Fuel Pool Filter/Demin high inlet temperature alarm setpoint?
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?
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?
What is the primary power supply for the Fuel Pool filter/demin system?
What is the Fuel Pool heat exchanger outlet high temperature alarm?
120F is the Fuel Pool pump suction temp
140F is the filter/demin high temp
150F is a distractor
