Reference:

Level RO ; SRO Tier # 1 Group # 1 K/A # 295001 AK2.06 IR 3.8 Knowledge of the interrelationships between PARTIAL OR COMPLETE LOSS OF FORCED CORE FLOW CIRCULATION and the following: Reactor Power. (41.7)

Proposed Question:

The following conditions exist:

Reactor Power 2400 MWth Core Flow 81 Mlbm/hour If one reactor recirculation pump trips to OFF, reactor power will be approximately

___(1)___ and if both reactor recirculation pumps trip to OFF, reactor power will be

____(2)_.

A. (1) 61% power (2) 42% power B. (1) 42% power (2) 0 % power C. (1) 51% power (2) 0% power D. (1) 51% power (2) 42% power Proposed Answer: C.

Explanation:

A. See C.

B. See C.

C. Correct-Current rod line is 80%. As flow from the first pump trip drops off, core flow will be about half the original value.

Moving to the left of the Power to Flow map on the 80% rod line to ~42.5Mlb/hr yields a core power value of ~1600MWth

(~51%). If both pumps trip, continuing to move along the 80% rod line indicates that the Exclusion Region is entered which results in a reactor scram (0% power).

D. See C.

Proposed Question:

The reactor has scrammed and the Main Turbine has tripped from 100% power operation. The transient was initiated by a grid disturbance which caused a trip of the Main Generator.

Which of the following describes the reasons these trips occurred?

The turbine tripped to ______(1)______.

The reactor scrammed _____(2)_______.

A. (1) provide protection from a turbine overspeed condition due to the sudden unloading of the generator.

(2) in anticipation of pressure and flux transients due to the tripping of the turbine.

B. (1) protect the Main Generator from motoring.

(2) in anticipation of pressure and flux transients due to the tripping of the turbine.

C. (1) provide protection from a turbine overspeed condition due to the sudden unloading of the generator.

(2) due to an RPV low water level condition resulting from the turbine trip.

D. (1) protect the Main Generator from a reverse power condition.

(2) due to an RPV low water level condition resulting from the turbine trip.

Proposed Answer: A.

Explanation:

A. On any generator trip the turbine trips to avoid a turbine overspeed condition due to no load on the generator. The reactor scrams in anticipation of pressure and flux transients due to the tripping of the turbine.

B. The output breakers opening protects the main generator from motoring.

C. The reactor scram is in anticipation of pressure and flux transients due to the tripping of the turbine. Although the pressure rise from a turbine trip would cause a reduction in RPV level it would not initiate a reactor scram.

D. The generator protection from reverse power is the opening of the output breakers, not a turbine trip. The reactor scram is in anticipation of pressure and flux transients due to the tripping of the turbine. Although the pressure rise from a turbine trip would cause a reduction in RPV level it would not initiate a reactor scram.

Proposed Question:

The instrument air compressors are all available and operating with the local SEQUENCE CONTROL switch in Position 3 (C-A-B). Only the IAS-C2C has been operating to maintain system pressure.

A relay failure in the control circuit for compressor IAS-C2C causes it to shutdown.

With no change in Instrument Air System usage, which of the following describes the effect of the compressor shutdown on the Instrument Air System?

A. IAS-C2A operates alone, maintaining a lower header pressure.

B. IAS-C2B operates alone, maintaining a lower header pressure.

C. Both compressors IAS-C2A and C2B are operating, maintaining the same header pressure.

D. Both compressors IAS-C2A and C2B are operating, maintaining a lower header pressure.

Proposed Answer: A.

Explanation:

A. Correct-IAS-C2A is the second compressor to sequence on in Position 3, so it will start as pressure lowers to the mid range setpoint (115.5 psig) which is lower than the pressure setpoint for the start of IAS-C2C (118.5 psig).

B. IAS-C2B is the third compressor to start in Position 3 (109.5 psig), therefore it will not run before IAS-C2A.

C. With system demand unchanged, there is no need for two compressors to run. Additionally, system pressure will not be maintained the same as before (118.5 psig) the failure because IAS-C2A is being controlled by the mid range pressure switches (115.5 psig) in Position 3.

D. With system demand unchanged, there is no need for two compressors to run.

Proposed Question:

The basis for the operability requirements for Technical Specification 3.3.4.2 ATWS-RPT Instrumentation is to ensure the reactor recirculation pumps ___________.

A. trip to OFF to insert negative reactivity due to voiding caused by the reduction in core circulation during a failure to scram.

B. transfer to SLOW speed to insert negative reactivity due to voiding caused by the reduction in core circulation during a failure to scram.

C. trip to OFF to reduce the peak reactor pressure resulting from a turbine trip or generator load rejection transient to provide additional margin to core thermal MCPR safety limits.

D. transfer to SLOW speed to reduce the peak reactor pressure resulting from a turbine trip or generator load rejection transient to provide additional margin to core thermal MCPR safety limits.

Proposed Answer: A.

Explanation:

A. Correct - The tripping of the recirculation pumps during an ATWS inserts negative reactivity as more voiding occurs in the core to the reduced removal of heat due to less core circulation/heat removal.

B. The reason is correct, but the pumps trip to OFF, not SLOW speed.

C. Trip to off is correct, but the reason is incorrect. This reasoning is the bases for the End of Cycle Recirc Pump Transfer.

Proposed Question:

A plant transient has resulted in a loss of all injection sources except Reactor Core Isolation Cooling (RCIC). Reactor pressure is 260 psig and continues to slowly lower.

As pressure continues to lower toward the steam supply pressure isolation setpoint, which of the following should the CRS direct?

• Enclosure 2, DEFEATING RCIC LOW PRESSURE ISOLATION INTERLOCKS

• AOP-0003, AUTOMATIC ISOLATIONS A. Install EOP Enclosure 2 before RCIC isolates at 150 psig.

B. Install EOP Enclosure 2 before RCIC isolates at 60 psig.

C. Verify RCIC isolates at 60 psig in accordance with AOP-0003.

D. Verify RCIC isolates at 150 psig in accordance with AOP-0003.

Proposed Answer: B.

Explanation:

A. The action is correct, but 150 psig is the LCO applicability value not the isolation setpoint.

B. Correct - Even though the isolation normally would occur at 60 psig, the EOP takes priority over the AOP isolation verification because the system is needed to maintain adequate core cooling. In the hierarchy of documents, the EOP takes precedence over the AOP. Subsequent guidance exists in EOP-0003 to isolate RCIC if it were to begin leaking into secondary containment.

C. Allowing RCIC isolation is inappropriate since it is the only injection source available. RCIC should be protected from isolation from guidance in the EOPs versus verification of isolation per the AOP.

D. . Allowing RCIC isolation is inappropriate since it is the only injection source available. RCIC should be protected from isolation from guidance in the EOPs versus verification of isolation per the AOP.

D. Both Division 1 & Division 2 MS-PLCS are unavailable. Enter AOP-0050 Station Blackout to manually align the Instrument Air System as a backup to MS-PLCS.

Proposed Answer: A.

Explanation A. Correct - Division 1 MS-PLCS pressurizes the area between the inboard and outboard MSIVs. A 5 minute timer bypasses any high flow isolation signals during the initial flow of air as the system is being pressurized. After 5 minutes, if air flow is still high, the system will isolate. In the stem it is stated that seat leakage was 15 scfm which is higher than the 14 scfm isolation signal. Isolations are verified by AOP-0003.

B. Div 2 does not attempt to pressurize the area between the inboard and outboard MSIVs so will not be affected by the failure.

C. Division 1 will not continue to operate. See A.

D. Division 2 will be unaffected. In addition the referenced procedure section from AOP-0050 applies when the MS-PLCS air source is not available which is not the case here.

Proposed Question:

The following occurred during Mode 1 operation:

• 11/1/2012 @ 1530 HVR-UC1A tripped; HVR-UC1B remains in service

• 11/1/2012 @ 1540 HVR-UC1C is placed in service,

• 11/1/2012 @ 1540 Peak containment temperature is 81°F Which of the following defines the Technical Specification requirements?

A. Per TS 3.6.1.7 PRIMARY CONTAINMENT UNIT COOLERS, HVR-UC1A must be restored to OPERABLE by 11/8/2012 @ 1530. Entry into TS 3.6.1.5 PRIMARY CONTAINMENT AIR TEMPERATURE is required.

B. TS 3.6.1.7 was entered at 1530 and exited at 1540. Entry into TS 3.6.1.5 PRIMARY CONTAINMENT AIR TEMPERATURE is required.

C. TS 3.6.1.7 was entered at 1530 and exited at 1540. Entry into TS 3.6.1.5 PRIMARY CONTAINMENT AIR TEMPERATURE is NOT required.

D. Per TS 3.6.1.7 PRIMARY CONTAINMENT UNIT COOLERS, HVR-UC1A must be restored to OPERABLE by 11/8/2012 @ 1530. Entry into TS 3.6.1.5 PRIMARY CONTAINMENT AIR TEMPERATURE is NOT required.

Proposed Answer: D, Explanation:

A. First part is correct, but entry into the Containment Temperature Spec is not required until temperature exceeds 90°F B. HVR-UC1C does not satisfy TS 3.6.1.7 and the Containment Temp Limit is 90°F.

C. HVR-UC1C does not satisfy TS 3.6.1.7. Part 2 is correct.

D. Correct - HVR-UC1C does not satisfy the requirements of TS 3.6.1.7 and cannot be counted towards the two required operable coolers. Condition A must be entered at the time of the UC trip. Condition A has a Completion Time of 7 days therefore restoration is required by 11/8/2012 @ 1530. The TS limit for containment temperature is >90°F so entry into that specification is not required.
