What two independent Tech Spec systems are utilized to detect an unidentified RCS leakage rate of 1 gpm within a one hour period after it begins?
CTMT atmosphere monitor CMS22-2 and the CTMT sump level/pumped capacity monitoring system
Which of the following describes the relationship of the incore instrument sump pump, CTMT unidentified sump, and CTMT identified sump?
the incore sump and the unidentified sump are pumped to the identified sump, which is pumped to radwaste
When using the containment personnel hatch pressure equalization ball valves for airlock pressure control or D/P check, and the airlock is occupied, what is the max allowed pressure equalization rate?
0.5 psi per minute
How does the containment isolation phase A (CIA) signal affect the ability to pump the containment sump (identified leakage sump 3)?
the pumps 3DASP2A and P2B are prevented from starting, since the downstream CTVs (CTV24 and *CTV25) trip closed when CIA actuates
When placing the containment atmosphere and leak monitoring system in service, the first step verifies at least one CAR fan running. Why is it necessary to have one CAR fan running?
to provide a representative air sample to the radiation monitors
During an emergency breaking of containment vacuum, which valves open and why?
3HVU*CTV33A / to align CTMT purge system to CTMT atmosphere
3DAS-P10, unidentified leakage sump pump, transfers the contents of the unidentified sump to:
3DAS-SUMP3, containment (identified leakage) drains sump
Plant at 100% power
Four people enter CTMT
When exiting, the CTMT outer personnel hatch jams
The emergency escape many hatch will be used
What precaution is required to be observed while exiting via the emergency escape manway?
be aware that severe personnel injury could result to to D/P across the manway
Crew desires to break CTMT vacuum
Enters AOP 3568
Crew desires to exceed max depressurization rate stated in OP 3313F
Is the crew able/allowed to exceed the 10 psi/hr repressurization limit?
yes, since AOP 3568 gives permission to exceed the rate
What team members are required during a containment entry per C OP 200.14?
team leader and containment air lock operator only
During normal operation, unidentified sump pump becomes inoperable. Which of the following is the most likely consequence?
the unidentified leakage sump will overflow into the identified leakage sump
During pressure equalization, other members complain of ear pain due to rapid equalization. What actions are required?
press the “EMERG.STOP” PB at 3PHS-PNLC
What is the criterion for installing temporary cooling to the CTMT personnel hatch door hydraulic motors?
the personnel hatch door will be continuously cycled
