E-1 Support & Contingency Procedures (RQ-C-4721) Flashcards
1
Q
When would you transition to ES-1.2 (Post LOCA Cooldown & Depressurization) from ES-1.2 (SI Termination)
A
- After stopping ECCS pumps and Pressurizer pressure/level lower
2
Q
If RCS pressure is lowering after isolating the BIT and a faulted SG is still blowing down, what actions are taken in ES-1.1 (SI Termination)
A
- Loop in the procedure until SG blowdown is complete
3
Q
As RCS pressure lowers, break flow _____, SI flow _____, and PZR level will _____
A
- Lower
- Rise
- Rise
4
Q
Which action in ECA-1.1 (Loss of Emergency Coolant Recirculation) will conserve the greatest volume of water in the RWST
A
- Stopping both CTS pumps will result in an extra 150 minutes of RWST usage
5
Q
Why do you NOT perform ECA-1.2 (LOCA Outside Containment) if you are aligned to cold leg recirculation
A
- Because ECCS recirculation flow paths are isolated in ECA-1.2 which would lead to pump damage if you are already on CL recircuation
6
Q
What are the ECCS design pressure & flow for a CCP
A
- 2300#
- 550 gpm
7
Q
What are the ECCS design pressure & flow for a SI pump
A
- 1600#
- 600 gpm
8
Q
What are the ECCS design pressure & flow for a RHR pump
A
- 200#
- 4500 gpm
