Containment/Containment Ventilation/Incore Instrumentation (RQ-I-4771) Flashcards
1
Q
What automatically actuates a Containment Ventilation Isolation
A
- SI
- Containment Hi Radiation Alarm
2
Q
Which instruments make up the RCS leak detection system
A
- Sump monitors
- Radiation monitors
3
Q
What is the cooling medium for Containment Ventilation during closed-loop (normal) operation
A
- Containment Chilled Water
4
Q
For Containment Purge & Exhaust system which flow rates are designed to be higher (purge or exhaust) and why
A
- Exhaust flow rates for LOWER containment are higher to minimize the spread of contamination
5
Q
Which Containment Isolation signal trips the CRDM vent fans
A) Phase A
B) Phase B
C) CVI
A
B) Phase B
6
Q
How is indicated temperature effected when an RTD shorts vs opens
A
- Short = Resistance is 0, temperature fails low
- Open = Resistance is infinite, temperature fails high
7
Q
How is indicated temperature effected when an Thermocouple shorts vs opens
A
- Shorts = Voltage is 0, temperature fails low
- Open = temperature fails low
