Proposed Question: Common 3 Which of the following describes the MAIN reason for maintaining a Hydrogen overpressure in the Volume Control Tank (VCT) during plant operation at power?

A. Minimizes amount of radioactive gas diverted to the Waste Gas System during plant power changes.

B. Provides adequate Charging Pump suction pressure to minimize discharge accumulator pulsations.

C. Minimizes oxygen based corrosion of Reactor Coolant System components.

D. Provides an inert gas to minimize the formation of a hard bubble in the Pressurizer steam space.

Proposed Answer: C Explanation:

A. Incorrect. Plausible because hydrogen does help to scavenge oxygen created by radiolysis, however, the amount of diverted gas is a function of the Primary Sampling System piping size.

B. Incorrect. Plausible because the hydrogen overpressure does increase Charging Pump suction pressure, however, accumulator pulsations are minimized by the Nitrogen pressure inside the accumulator itself.

C. Correct. Hydrogen overpressure scavenges oxygen which minimizes corrosion of RCS components.

D. Incorrect. Plausible because the formation of a hard bubble in the Pressurizer steam space is undesirable, however, hydrogen is not an inert hard bubble gas.

• An Excess Steam Demand Event has occurred on Steam Generator E-088 inside Containment.

• The cooldown caused a rapid depressurization of the Reactor Coolant System (RCS) to 1100 psia.

• MSIS, CIAS, SIAS, CCAS and CSAS have fully actuated.

• NO operator actions have been taken.

Which of the following:

1.) Identifies the impact on the RCS when Steam Generator E-088 reaches dryout?

2.) Actions should be taken to mitigate the situation?

A. 1.) Heat Removal will stop and due to the cooldown and excessive differential temperature will exist between the Pressurizer and RCS.

2.) When dryout occurs, initiate depressurization of the RCS to reduce subcooling to 20ºF to 50ºF.

B. 1.) An excessive differential temperature will exist between the two loops and could cause thermal shock at the Reactor Vessel inlet nozzles.

2.) When dryout occurs, reduce the hotter loops temperature using Steam Generator E-089 to within 20ºF of the affected loop.

C. 1.) Heat Removal will stop with the RCS at a higher mass and if allowed to heatup could cause a Pressurized Thermal Shock condition.

2.) Prior to reaching dryout, dump steam from E-089 to maintain < 200 psi above E-088 and stabilize E-089 pressure at PSAT for the lowest TCOLD after dryout.

D. 1.) Heat Removal will stop with the RCS at a higher mass and if allowed to heatup could cause the Pressurizer to go solid.

2.) Dump steam from E-089 to maintain the highest TCOLD stable without cooling down further and then immediately throttle Safety Injection.

ES-401 SONGS NRC 2010 RO Written Exam Worksheet Form ES-401-5 Proposed Answer: C Explanation:

A. Incorrect. Plausible if thought that the issue was the T between the Pressurizer and RCS Loops and reducing the pressure would reduce this T, however, the increased mass of the Reactor Coolant and subsequent heatup could cause a Pressurized Thermal Shock (PTS) condition if actions arent taken to stabilize at the lowest TCOLD.

B. Incorrect. Plausible if thought that the issue was the T between the RCS Loops and reducing the temperature in the least affected Loop would narrow this differential, however, if temperature isnt stabilized at the lowest TCOLD then a subsequent heatup could cause a Pressurized Thermal Shock condition due to the increased mass from Safety Injection.

C. Correct. The increased mass of the Reactor Coolant System and subsequent heatup could cause a Pressurized Thermal Shock condition if actions arent taken to stabilize at the lowest TCOLD.

D. Incorrect. Plausible if thought that reducing pressure in the least affected Steam Generator would add to the total excessive cooldown, however, if temperature isnt stabilized at the lowest TCOLD then a subsequent heatup would occur and cause PTS.

A. Incorrect. Plausible because Main Feedwater Pump speed used to lower to 3000 rpm (prior to Digital FWCS installation), however, it will modulate to control P and the Bypass Valves open to 50%. The 5% value is a misconception as this is the design power level for adequate feed flow using the Bypass Valves.

B. Incorrect. Plausible because the action of the Main Feedwater Pump is correct, however, the 5%

value is a misconception as this is the design power level for adequate feed flow using the Bypass Valves.

C. Incorrect. Plausible because the Bypass Valve positioning and initial lowering of Main Feedwater Pump speed was correct before the Digital FWCS installation, however, speed will modulate to control valve P.

• Instrument Air header pressure at the ADV is 10 psig and lowering.

Assuming Instrument Air is completely lost, which of the following describes the impact on the operation of the Atmospheric Dump Valve?

A. Valve fails open because there is no pressure to keep the valve closed.

B. Supply pressure for valve operation is below allowed values but spring pressure will assist with valve opening.

C. Manual operation only is available because the Nitrogen Backup Supply is lost through the same check valve.

D. Normal operation is lost but valve closure on a Main Steam Isolation Signal is maintained by the Nitrogen Backup Supply.

Proposed Answer: C Explanation:

A. Incorrect. Plausible if thought that the valve fails open, however, the valve fails closed.

B. Incorrect. Plausible because supply pressure is below allowed values and there is spring pressure applied to the valve, however, the spring pressure is designed to fail the valve closed.

• 2LT-0226, Volume Control Tank Level Transmitter has failed low.

Which of the following describes the effect on the Chemical and Volume Control System (CVCS) for this failure?

A. The Refueling Water Storage Tank is aligned to the Charging Pump suction with no override capability.

B. The Refueling Water Storage Tank is aligned to the Charging Pump suction but can be manually realigned to the Volume Control Tank.

C. The signal from 2LT-0226 is rejected and 2LT-0227 becomes the selected signal to prevent any spurious CVCS actuations.

D. A continuous makeup to the Volume Control Tank is in progress and will divert Letdown to Radwaste on high level.

Proposed Answer: C Page 80 of 111 Rev g

ES-401 SONGS NRC 2010 RO Written Exam Worksheet Form ES-401-5 Explanation:

A. Incorrect. Plausible if thought that the transmitter that provided indication and low level alarm, LT-0226, also provided the automatic swap to the Refueling Water Storage Tank with no override capability, however, this feature is from LT-0227 which has not failed and the swapover valving can be overridden to align to the Volume Control Tank. This condition is no longer true on Unit 2.

B. Incorrect. Plausible because it could be thought that transmitter LT-0226 provided the automatic swap to the Refueling Water Storage Tank, however, this feature is from LT-0227 which has not failed. This condition is no longer true on Unit 2.

C. Correct. When the Boration Distributed Control System was installed during the Cycle 16 Refueling Outage it specifically prevented failure of either VCT Level Transmitters (LT-0226 and LT-0227) from causing either VCT diversion to the RWST (LT-0227) or initiation of auto makeup (LT-0226).

This signal is now averaged from both instruments and a replacement value is sent to the DCS should a transmitter fail high or low.

D. Incorrect. Plausible because this is the effect of the failure on Unit 3 which is not yet equipped with the Distributed Control System. If no actions were taken to stop the makeup, the high level diversion of Letdown to Radwaste feature is from LT-0227 which did not fail.

• The Pressurizer Pressure Transmitter for the controlling channel fails high.

With NO operator action, which of the following is the first AUTOMATIC plant response as a result of this malfunction?

A. Both Pressurizer Spray Valves close.

B. Reactor trip due to low pressure.

C. All Pressurizer Backup Heaters energize.

D. Reactor trip due to high pressure.

Proposed Answer: B Explanation:

A. Incorrect. Plausible if thought that once pressure drops below 2275 psig the Spray Valves will fully close, however, given the condition of the controlling channel, the Spray Valves remain open.

B. Correct. When the Pressurizer Pressure Transmitter fails high, both Spray Valves open. This causes pressure to lower until a low pressure Reactor trip is generated. See Figure III-4 from SD-SO23-360 (attached), the Pressurizer Pressure Control Channels are separate from the Pressurizer Pressure Plant Protection System Channels.

C. Incorrect. Plausible because the Pressurizer Backup Heaters would energize once pressure drops below 2200 psig, however, the Heaters are locked out when the Pressurizer Pressure Transmitter fails high at 2340 psig.

D. Incorrect. Plausible if thought that when the controlling channel fails high the Reactor will trip on high pressure.

Proposed Answer: D Explanation:

A. Incorrect. Plausible because SO23-12-1 contains the diagnostic flow chart to determine the correct procedure to be entered, however, it does not contain the necessary actions to mitigate both events.

B. Incorrect. Plausible because during performance of Step 2, Verify LOCA Diagnosis it would be determined that two events were in progress and SO23-12-9, Functional Recovery should be entered, however, SO23-12-3 does NOT provide the guidance to mitigate both events.

C. Incorrect. Plausible because if SO23-12-5 were entered, Step 2, Verify ESDE Diagnosis would determine that two events were in progress and SO23-12-9, Functional Recovery should be entered; however, SO23-12-5 does NOT provide the guidance to mitigate both events.

ES-401 SONGS NRC 2010 RO Written Exam Worksheet Form ES-401-5 Explanation:

A. Incorrect. Plausible because this answer could be arrived at if an error is made calculating the square root of the differential pressure to determine flow rate.

B. Incorrect. Plausible if thought that 1/2 of the differential pressure present would result in 1/2 of the original leak rate if a Ratio & Proportion calculation was used.

C. Correct. Leak rate is proportional to the square root of the differential pressure. 1/2 of the original P will correspond to approximately 70% of the original leak rate. The operational implications of this are important when evaluating the ability to remove adequate decay heat post-trip.

D. Incorrect. Plausible if thought that the leak rate would increase because Steam Generator pressure is higher.

Proposed Answer: B Page 4 of 110 Rev g

ES-401 SONGS NRC 2010 SRO Written Exam Worksheet Form ES-401-5 Explanation:

A. Incorrect. Plausible because entry into SO23-13-28 would be required if a Main Feedwater Pump had tripped with the Unit at 100% power; however, because the Main Feedwater Pump trip is accompanied by an Instrument Air header leak, the Reactor must be tripped.

B. Correct. This is the required action because plant systems have become unstable (i.e., tripping of Main Feedwater Pump, fluctuating Steam Generator levels, etc.) even with Instrument Air header pressure greater than 50 psig.

C. Incorrect. Plausible because Instrument Air pressure has stabilized, however, plant systems have become unstable and a Reactor Trip is required.

D. Incorrect. Plausible because action is required per SO23-13-5 if Instrument Air header pressure is less than 50 psig, however, SO23-13-5 requires an earlier trip of the Reactor if plant systems become unstable.

• Unit 2 has tripped following a Bus 2A07 overcurrent trip and loss of Condenser vacuum.

• Auxiliary Feedwater (AFW) Pump P-141 breaker will not close and AFW Pump P-504 was cleared for Boundary of the Week.

• AFW Pump P-140 is running but cannot develop sufficient discharge head.

• SO23-12-1, Standard Post Trip Actions, is complete.

• SO23-12-6, Loss of Feedwater, is in progress.

• The cause of the loss of vacuum was identified and Condenser vacuum is restored.

• Main Feedwater Pump P-062 was RESET and available for use.

Shortly after entry into SO23-12-6, the following occurs:

• Annunciator 57C57 - TURBINE BLDG FLOODING has just alarmed.

• A Main Feedwater pipe rupture was verified between the Turbine Building and the Safety Equipment Building.

Proposed Answer: A Page 13 of 110 Rev g

ES-401 SONGS NRC 2010 SRO Written Exam Worksheet Form ES-401-5 Explanation:

A. Correct. As outlined in SO23-12-6, Step 8.b, a transition to the Functional Recovery Procedure must be performed.

B. Incorrect. Plausible because a Condensate Pump would be available from Bus 2A03 since there is not a Loss of Offsite Power and it did not incur an overcurrent trip, however, there are two events in progress and entry into SO23-12-9 is required. Otherwise, without Condensate Pumps available SO23-12-6 would direct entry into SO23-12-9 at Step 10.

C. Incorrect. Plausible if thought that the Steam Generators could continue to be fed, however, a transition to SO23-12-9 is warranted.

D. Incorrect. Plausible because rediagnosis would be appropriate to ensure correct procedure is being entered and it would be performed as part of the Safety Function Status Checks (since SO23-12-1 is complete), however, there are two events in progress and this would require entry into SO23-12-9, Functional Recovery.

D. Perform actions of SO23-12-11, EOI Supporting Attachments, Attachment 14, RAS Operations to raise RWST level in order to flood Containment above the 23 (foot) level to improve Net Positive Suction Head to the operating HPSI Pump.

Proposed Answer: A Page 22 of 110 Rev g

ES-401 SONGS NRC 2010 SRO Written Exam Worksheet Form ES-401-5 Explanation:

A. Correct. Given the conditions listed, remaining in SO23-12-3 is appropriate and cross connecting CCW places Unit 2 in a 50.54.X notification.

B. Incorrect. Plausible because HPSI Pump P-019 is available (P-018, the 3rd of a kind Pump will start on an SIAS, therefore, P-019 is available to run) and might be considered, however, according to Step 5 EOI Bases, it will only increase flow marginally, if at all, and one operating train is sufficient at his time. Transitioning to the FR is plausible as this is the RNO action in Floating Step 22 if HPSI Pump flow becomes unstable.

C. Incorrect. Plausible because it could be thought that the FR is the procedure required for this condition, however, one Train is all that is required given the conditions listed and cross connecting with Unit 3 CCW places Unit 2 in a 50.54.X notification.

D. Incorrect. Plausible because refilling the RWST would be a desired action given the loss of CCW and raising level does improve HPSI Pump NPSH, however, flooding above the 225 level will impact the Emergency Cooling Unit ductwork and could complicate the loss of CCW that already exists.

• All Control Element Drive Mechanism Cooling has been lost for one (1) hour.

• A Containment entry to investigate the cause has been delayed.

Which of the following actions should be directed by the Control Room Supervisor?

A. Trip the Reactor and then perform SO23-5-1.5, Plant Shutdown from Hot Standby to Cold Shutdown, to initiate a plant cooldown to less than 350ºF.

B. Enter SO23-3-2.22, Engineered Safety Features Actuation System Operation, and initiate a Containment Cooling Actuation Signal on one (1) train.

C. Enter SO23-1-4, Containment Normal Heat Removal, Operation of the Reactor Cavity Cooling Units, and start a second fan in each set to cool the area around the Reactor.

D. Refer to SO23-15-60.A1 - CEDM COOLING SHROUD TEMP HI, and verify Control Element Drive Mechanism Cooling Unit Dampers OPEN to promote Natural Circulation cooling.

Proposed Answer: A Explanation:

A. Correct. These are the required actions per Operating Instruction SO23-1-4 and Annunciator SO23-15-60A1, 60A13. Entry into SO23-5-1.5 will facilitate the cooldown.

B. Incorrect. Plausible if thought that the additional cooling using Containment Emergency Cooling Units would be the appropriate strategy to keep the CEDM temperatures within design, however, this is a strategy for a high temperature condition on the shroud or coils but the Reactor is required to be tripped prior to exceeding one hour with a total loss of cooling and a plant cooldown to

Proposed Answer: B Page 83 of 110 Rev g

ES-401 SONGS NRC 2010 SRO Written Exam Worksheet Form ES-401-5 Explanation:

A. Incorrect. Plausible if thought that this fire only affected Unit 2 and that 10 minutes was the E-Plan criteria for an UNUSUAL EVENT, however, the UE Classification requires that the fire is active for 15 minutes. SO23-13-21, Fire, directs that if the fire has not been contained within 10 minutes then both Units are tripped.

B. Correct. This MCC contains equipment that can affect both Units and SO23-13-21, Fire, directs that if the fire has not been contained within 10 minutes then both Units are tripped and SO23-12-1, Standard Post Trip Actions, are performed. Additionally, SO23-13-21 actions with less than or equal to one hour time limits are performed.

C. Incorrect. Plausible because it could be thought that for a fire in this area then SO23-13-2, Shutdown from Outside the Control Room would be invoked and the other actions stated would be correct, however, this is not one of the zones that direct SO23-13-2 actions.

D. Incorrect. Plausible because for fires in other zones this would be a consideration and the compensatory actions are required, however, this area contains equipment affecting both Units.
