A high level in any MSR level instrument will cause a turbine trip. However, since Rx power is within the capability of the bypass valves, the Rx does not scram.
A - Incorrect - Plausible is operator believes Rx will scram but no turbine trip will occur if generator not synchronized to grid.
C - Incorrect - No Rx scram will occur. Plausible if operator assumes a turbine trip at this power level will cause a Rx scram.
D - Incorrect - Plausible since most other logic trip systems are at least 1 out of 2, not single input.

SCRAM Condition Present and Power Above APRM Downscale or Unknown Explanation: Answer D - With a loss of off-site power, and the HPCS DG the only DG running, but the pump is unavailable, then ONI-R10 TLAC is entered. Since RCIC auto started, RPV level lowered to <L2 then EOP-1 is also entered. And, since one SRV is open and one SRV is cycling, the reactor is still producing power and above 4% (1 SRV5%) EOP-1A is also entered.
A - Incorrect - Plausible since the Div 3 DG is running. But, without the HPCS pump, TLAC is entered. Also since 1 SRV is open and 1 is cycling, ONI-B21-1 is also plausible.
B - Incorrect - Plausible since 1 SRV is open and 1 is cycling. But, this indicates the Rx is still making power.

If demin inlet temp rises >140°F, the resin can breakdown and release collected contaminants. If G33-F107 fails open, the Regenerative HX is bypassed causing the demin inlet temp to rise.
A - Incorrect - At rated power both the INBD and OTBD isolation valves are closed. Therefore, opening one would not have any effect.
B - Incorrect - This valve is open at power with RWCU in service.
C - Incorrect - This valve is open when RWCU in service. Plausible since it may be confused with G33-F044.

Reactor power Incomplete SCRAM Explanation: Answer D - With 2 SRVs open and RPV pressure stable at 900 psig, Rx power is approximately 8-10%. This will require the SRO to direct action from EOP-1A, which requires injection remain Terminated and Prevented until one of several conditions are met. APRM's Downscale is a standalone condition that allows for recommencement of injection to stabilize RPV level.
A - Incorrect - Plausible since reinjection is allowed if SRVs are closed and Drywell pressure <1.68 psig.
B - Incorrect - Would be correct if level lowered to 16.5 inches. Plausible since this is the lower end of the level band if Suppression Pool temperature was <110°F.
C - Incorrect - This is partially correct. However, SRVs must remain closed to recommence injection.

Secondary Containment High Sump/Area Water Level Explanation: Answer D - Per a NOTE in EOP-3, when any area is inaccessible due to a hazard and the associated sump level annunciator is in alarm then the Max Safe operating Limit for that area is considered exceeded. With RHR B & C sump level alarms in and water in Aux 568, RHR B & C rooms are inaccessible and 2 max safes are exceeded. Since there is no indication of a primary system leaking, the SRO must commence a normal plant shutdown.
A - Incorrect - Plausible since ED is required if 2 or more areas of same parameter exceeded max safe if primary system discharging.
B - Incorrect - Plausible, since this is a required action. However, since there is water on Aux 568, operation of the cubical drain valves would not be possible without extraordinary measures. Additionally, 2 max safes are already exceeded.
C - Incorrect - Plausible since this is the required action if it was a primary system leaking.

RCIC Explanation: Answer B - With containment temperature at 186°F and rising 1°/min, ED is required by EOP-2.
The SRO needs to transition from EOP-2 to EOP-1 then to EOP-4-2 (ED). Since RCIC is injecting
@ 500 and RPV level is stable, RCIC is required for adequate core cooling. A NOTE in EOP-1 tells the US to terminate ED to maintain RCIC if required for ACC and directs a pressure band of 150 to 250 psig until RCIC no longer required for ACC.
A - Incorrect - Cooldown to <135°F is required to start SDC. However, based on containment H/U rate, ED will be required before SDC could be placed in service.
C - Incorrect - Maintaining TS cooldown rate is not required when ED is required.
D - Incorrect - Maintaining TS cooldown rate is not required when ED is required.
