Q

What can happen if RCS pressure is maintained below VCT pressure for extended periods?

A

With RCS pressure maintained below VCT pressure for extended periods, dissolved gas accumulation should be anticipated in RCS highpoints. RVLIS should be monitored for void growth

Q

If the pressurizer cooldown rate Tech Spec or Administrative limits are exceeded as a consequence of a thermal stratification, the ______ shall be notified for an evaluation

A

Shift manager

17
Q

How many SR channels are required to be operable with reactor shutdown and rod control capable of rod withdrawal?

A

Two Source Range Channels shall be OPERABLE anytime the Reactor is shutdown and with Rod Control System capable of rod withdrawal or one or more rods not fully inserted, per Tech Spec 3.3.1.

18
Q

BDPS is considered inoperable if ANY of the following conditions are NOT met:

A

1). All RCS Loop Stop Isolation valves must be open. 2). At least 1 Reactor Coolant Pump must be running.
3). Both BDPS Alert Alarm Bypass switches must be in the NORMAL position.
4). Both 1LT-112 and 1LT-185 must be operable.
5). VCT LEVEL 1 and 2 are selected to different channels.

19
Q

What is required if a high negative SUR is observed during shutdown? Can rods be withdrawn?

A

In the event of a sustained start-up rate more negative than - 0.2 dpm with no rod motion, any subsequent outward motion is prohibited. Control rods shall either be driven into the core, or the reactor trip breakers shall be opened.
