What happens if a surveillance fails?
SR 3.0.1 SURVEILLANCE REQUIREMENT (SR) APPLICABILITY,
Failure to meet a Surveillance, whether such failure is experienced during the performance of the Surveillance or between performances of the Surveillance, shall be failure to meet the LCO.
You are in the middle of moving the 33rd irradiated fuel rod this outage. Red and White inverters fail out and lose power.
N-31 and N-32 no longer work so you dont have 2 operable SR channels and you do not have 1 SR Audible.
Immediately initiate action to restore one source range neutron flux monitor to operable status. (2 non-operable)
Immediately initiate action to isolate unborated water sources
(Audible Count)
LCO 3.4.5
RCS Loops, Mode 3
2 RCS loops shall be operable with one in operation
Control rod worth shall be identified in these modes

You are currently in a TSAC for RHR loop inoperable due to RHR pump failure, when loop is required to be operable. Maintenance has informed you that pump repairs are complete, and ready for testing. What happens to the clock during retest of the pump, and why?
Clock is stopped when equipment is considered operable
LCO 3.0.5 Equipment removed from service or declared inoperable to comply with ACTIONS may be operated under administrative control solely to perform testing required to demonstrate its OPERABILITY or the OPERABILITY of other equipment. This is an exception to LCO 3.0.2 for the system operated under administrative control to perform the testing required to demonstrate OPERABILITY.
LCO 3.0.2
If the LCO is met or is no longer applicable prior to expiration of the specified Completion Time(s), completion of the Required Action(s) is not required unless otherwise stated.
Containment has been declared inoperable.
Restore containment to operable status within 1 hour
LCO 3.5.3 One ECCS train shall be OPERABLE.
- NOTE: An RHR train may be considered OPERABLE during alignment and operation for decay heat removal, if capable of being manually realigned to the ECCS mode of operation.
ACTIONS
- NOTE: LCO 3.0.4.b is not applicable to ECCS high head subsystem.
TLCO 3.2.1
A minimum of how many thimbles are required
Correct answer is 8 or 2 per quadrant
A Primary Safety Valve lift setpoint.

After initial calibration must be within +/-1%
What is the generic definition of the term "Operable" in regards to tech specs?
A system, subsystem, train, component, or device shall be OPERABLE or have OPERABILITY when it is capable of performing its specified safety function(s) and when all necessary attendant instrumentation, controls, normal or emergency power, cooling and seal water, lubrication, and other auxiliary equipment that are required or the SSC to perform its specified safety function(s) are also capable of performing their related support functions.
You are in Mode 5 with Pressurizer level at 27 inches. SG A and B have been drained for radiography testing of vessel integrity. RHR Pump A has tripped due to grounds.
Initiate action to restore a second RHR loop to operable status
OR
Initiate action to restore SGWL to >35%
Reactor is at 4% RTP
NR-32 has been declared inoperable3.3.1
2 IRNI or 1 SRNI inoperable-suspend operations involving positive reactivity additions immediately
The squirtle squad is taking suction directly off the pump bay and discharging at 9000 gpm. CCW flow is currently at 8000 gpm.

Per LCO 3.4.7, when may an RHR loop be inoperable for 2 hours?
3.4 REACTOR COOLANT SYSTEM (RCS)
3.4.7 RCS Loops—MODE 5, Loops Filled, What does the Above the Line Note Mean?
NOTE:
2. One required RHR loop may be inoperable for up to 2 hours for surveillance testing provided that the other RHR loop is OPERABLE and in operation.
Tave is 186F
D-05 has been declared inoperable by pilot cell voltage.
3.8.5, 3.8.6, 3.8.7
Declare affected required features inoperable AND initiate actions to restore - immediatelyVerify pilot cells electrolyte and voltage meet category C requirements in table - 1 hour
Declare affected required features inop and initiate action to restore - immediately

What TLCO states you must have 2 Rx Vessel head vent paths, and what are they?
PRT and Containment Atmospher
TLCO 3.4.4
Accumulator is operable when...
1100-1136 cu.ft (6-49%)

You are at 12% RTP, rising in power following physics testing. During the rise of power a faulty instrument with the CVCS systems starts borating without prompt. The CO forgot his morning coffee and is slow to respond while the OS was picking which kringle he wanted. Rx power is now in the intermediate range when boration was secured. The other OS returning from the head when he realized that IRPI is no longer functioning. Is LCO 3.1.7 met?
Good discussion overall but going for not applicable, youre in mode 3 now or whatever.
