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.

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.

and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations: Reactor water level control system malfunctions Reactor Feedwater Explanation: Answer C - Loss of Instrument Air (IA) to the Heater Bay causes a loss of IA to the MPF FCVs which will initiate the MFP Freeze circuit. This will prevent the MFP FCVs from moving.

Additionally, it causes the MFP Flow controller to shift to manual. It also causes the MFP Recirc valve to fail open causing ~4000 gpm flow to be diverted from the RPV. This will cause RPV level to lower to the L3 scram setpoint since the MFP was at its flow limit. Per ONI-C34, Immediate Actions, a Rx scram is required before hitting L3.

A - Incorrect - The operator not be able to control RPV level since the MFP is at its limit and the recirc valve failed open.

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.
