How many CIVs are there per unit?
6
100
What will cause the lift pumps to auto-start?
TGOP discharge pressure 10 psig; Lift pump suction pressure must be 6 psig.
100
At what pressure will the standby LH pump start?
1300 psig
100
What is the purpose of the thermocouples in the turbine shell?
They measure turbine temperatures
100
How many fans are there per cooling tower?
13
200
What is the purpose of the CIVs?
Used to prevent overspeed from the stored steam in the MSRs and crossaround piping in the event of a load rejection.
200
What is the final backup supply of oil to the turbine bearings and what is its power supply?
EBOP, DPD.
200
What will cause the emergency seal oil pump to start?
Starts when Main Seal Oil Pump pressure is <110 psig?
200
What output from the thrust bearing wear detectors will cause a turbine trip?
3/4 probes at 42 mils of movement.
200
What are the power supplies to the cooling tower fans?
CT 1A and 2A - 1HTA. CT 1B and 2B - 2HTA. CT 1C and 2C 1HTA or 2HTA.
300
What is the maximum temperature rise across a thrust and journal bearing?
Trust - 45F and Journal - 50F
300
At what power are the steam seal systems (TL and TF) transferred to E bleed steam?
50%
300
What is the purpose of LG-5(Differential Pressure Regulating Valve)?
It maintains seal oil pressure 8 psig greater that Generator hydrogen pressure.
300
If high radiation is detected in the CSAE exhaust, what happens?
The CSAE exhaust is directed to the Aux Building Filtered Exhaust System.
300
What provides makeup to the KG system?
YM
400
What is the purpose of the turbine control valves?
They are used to prevent overspeed in the case of a load rejection.
400
List the LT turbine trips.
Low bearing oil pressure; 2/3 pressure switches @ 12psig. Low MOP discharge pressure; 2/3 pressure switches <100 psig and speed is >96%.
400
What are the turning gear starting interlocks?
>15 psig bearing oil pressure, Turbine Shaft speed than 1.5 rpm, all generator PCB's open, engages only if shaft speed is less than 100 rpm.
400
Where are the CSAE's vented to?
Unit 1 or 2 main vent (normally Unit 1)
400
What must the CO2 storage tank level be maintained at what level when purging the generator?
44%
500
TS-2 (spray control valve) begins to open at which temperature and is full open at which temperature?
140F and 200F
500
What is the purpose of the butterfly valve in the vapor extractor in the LT system?
It is used to main 1.5-2" of vacuum.
500
What is the LH temperature maintained at and what is used to control it?
135F, KR HXs cool the returning oil, and six heating pads maintain the reservoir space at 100F.
500
What causes a hard stall this and what will happen if it occurs?
If there is too much seal water in the pump, the pump will trip on overcurrent.
500
At what point does the core monitor system alarm? What happens when the alarm occurs? And whats the power supply to the core monitor?
60%, the Pyrolysate Collector automatically obtains a sample after 10 seconds, KPD.
