(1) trip the turbine (2) ensure the fuel cladding integrity safety limit is NOT violated D. (1) scram the reactor (2) ensure the fuel cladding integrity safety limit is NOT violated

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __A__

Explanation:

A) Correct. LOA-TG-101 states to trip the turbine if attachment A setpoints are exceeded.

This is true for both 11 and 12 bearings being above 10 mils. High turbine vibrations are an indication of an unbalanced condition and are a precursor to turbine damage.

B) Incorrect. Plausible because this would be correct above 25% RTP. LOA-TG-101 states to trip the turbine if attachment A setpoints are exceeded. This is true for both 11 and 12 bearings being above 10 mils. However, anytime you are required to trip the main turbine above 25%, a manual scram is required first to prevent an automatic reactor scram.

C) Incorrect. Plausible because the first part is correct for high vibrations on bearings 11 and

12. The second part would be correct for a turbine trip above 25% RTP.

D) Incorrect. Plausible because this would be correct above 25% RTP. LOA-TG-101 states to trip the turbine if attachment A setpoints are exceeded. This is true for both 11 and 12 bearings being above 10 mils. However, anytime you are required to trip the main turbine above 25%, a manual scram is required first to prevent an automatic reactor scram.

K/A Statement: Knowledge of annunciators alarms, indications, or response procedures: Partial or Complete Loss of Instrument Air.

Proposed Question: Question #79 Unit 2 was in Mode 2 following a refueling outage when a major seismic event occurred.

  • Drywell pressure is 20 psig and RISING
  • Containment flood level is 710 ft
  • 2PI-AA022, Instrument Air Header Pressure, indicates 90 psig and LOWERING IAW LGA-003, Primary Containment Control, the Unit Supervisor will direct the crew to LGA-VQ-202, Unit 2 Emergency Containment Vent to vent from the (1) in order to (2) .

(1) drywell using HVCS (2) stay within the Pressure Suppression Pressure curve D. (1) drywell using VQ (2) stay within the Pressure Suppression Pressure curve

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __A__

Explanation: This question examines the applicants knowledge of indications for a loss of instrument air, and how to vent the containment with a loss of instrument air. A major seismic event has caused a LOCA and an Instrument Air rupture. With drywell pressure at 20 psig and rising, the crew will be on Step 16 in LGA-003, which directs the crew to emergency vent the containment IAW LGA-VQ-202 prior to exceeding the PCPL. With a loss of instrument air, HCVS can be used to vent from the suppression chamber, or VQ can be used to vent from the drywell.

A) Correct. LGA-003 step 16 directs the crew to vent containment IAW LGA-VQ-202. With a loss of instrument air, the US will direct the crew to go to Section E.2.d and vent from the suppression chamber using HCVS to stay below PCPL.

B) Incorrect. Plausible as the crew has the option to vent using VQ, but with the loss of IA, the crew must vent from the drywell. The second part of the distractor is correct.

C) Incorrect. HCVS is used to vent from the suppression chamber and is not aligned to the drywell. The Pressure Suppression Pressure curve is used as criteria to initiate blowdown and not used for containment vent criteria.

D) Incorrect. Plausible as VQ can be used to vent from the drywell with a loss of instrument air.

The second part of the distractor is incorrect, as the Pressure Suppression Pressure curve is used as criteria to initiate blowdown and not used for containment vent criteria.

K/A Statement: Ability to determine and/or interpret the following as they apply to high reactor pressure: Suppression Pool Temperature Proposed Question: Question 80 The reactor was at 100% RTP when a SCRAM occurred due to a spurious MSIV closure:

  • Multiple control rods did NOT insert to at least the 02 position
  • One SRV is full OPEN and another is cycling OPEN/CLOSED Subsequently,
  • A Loss of Off-site Power occurred
  • RPV water level is -70" (inches) and STABLE
  • Suppression Chamber pressure is 1.8 psig and RISING SLOWLY
  • Suppression Pool temperature is 160oF and RISING SLOWLY
  • Suppression Pool Level is +1 ft
  • Drywell Temperature is 130oF and RISING SLOWLY
  • The crew is injecting with SBLC What action will the Unit Supervisor direct NEXT?

A. Using LGA-001, RPV Control reset isolations and reopen MSIVs, stabilize RPV pressure below 1059 psig using main turbine bypass valves.

B. Using LGA-010, Failure to SCRAM rapidly lower RPV level until power drops below 3% or level drops to -120 inches on WR or all SRVs stay CLOSED and Drywell pressure stays below 1.93 psig.

C. Using LGA-003, Primary Containment Control and start Drywell Sprays to lower drywell temperature.

D. Using LGA-004, RPV Blowdown prevent LPCS and LPCI not needed for core cooling.

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___B___

Explanation:

A) Incorrect. Plausible as the crew would initially enter LGA-001 with APRMs above downscale with a scram signal present. The crew should transition to LGA-010 due to multiple control rods out. If they didnt recognize this and remained in LGA-001, they would direct this action under the pressure control leg if a loss of offsite power didnt occur and the condenser was available.

B) Correct. The US would be in LGA-010, Failure to SCRAM and with power above 3%, RPV Level above -120 inches on WR, and SRV OPEN, and Suppression Pool Temperature >

110F, the override step has the US direct lowering RPV level until power drops < 3% OR RPV Level -120 inches OR SRVs stay closed AND DW pressure stays below 1.93 psig.

C) Incorrect. Plausible as LGA-003 directs starting drywell sprays if Drywell Temperature is greater than 135 F. Although this condition is not presently met the candidate could see that it is trending towards that values.

D) Incorrect. Plausible if the candidate loses sight of not meeting the entry conditions of LGA-004 since there has not been a spurious or valid automatic actuation of ADS.

(1) exit (2) LGA-FW-201 Alternate Vessel Injection Using MDRFP By Defeating MDRFP High Level Trip to restore reactor cavity level

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __A__

Explanation:

A leak has occurred in Mode 5 with the fuel gates just being installed. IAW LGP-3-5, the reactor cavity level should be maintained between 480 and 485. The crew will implement LOA-NB-202. With the cavity level lowering, the crew will restore level using one of many emergency makeup sources, the first one listed is from the main feed system using LGA-FW-201, while concurrently performing the steps in LOA-NB-202. The crew will establish secondary containment, but the crew will not exit LOA-NB-202 or implement LGA-002. Secondary containment is established in LOA-NB-202.

A) Correct. LOA-NB-202 directs the crew to enter LGA-FW-201 to restore cavity level while concurrently performing the actions in LOA-NB-202.

B) Incorrect. Plausible because the first part of the distractor is correct, and because with a reactor cavity leak, the crew will establish secondary containment but the entry conditions for LGA-002 are not met.

C) Incorrect. Plausible because with a reactor cavity leak, the crew will establish secondary containment, but LOA-NB-202 does not direct the crew to exit the procedure, and the entry conditions for LGA-002 are not met.

D) Incorrect. Plausible because the second part of the distractor is correct, the crew will NOT exit LOA-NB-202.

  • A Group 1 isolation occurred
  • NO rods moved following the ATWS choreography Subsequently,
  • A leak developed in the Drywell
  • Suppression Pool Water Temperature is 160oF and RISING
  • Containment Flood Level is 725 ft due to CY leaking into RHR
  • RPV Pressure is at 950 psig

Spray the Suppression Chamber and Drywell per LGA-003 and Emergency Vent the Drywell per LGA-VQ-102, Emergency Containment Vent

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___B___

Explanation:

A) Incorrect. Plausible as the US should direct these actions per LGA-010 if the crew were not performing LGA-006 as required by primary containment conditions and LGA-003. The override step in the power leg of LGA-010 precludes performing reopening the MSIVs if LGA-006 is in use.

B) Correct. With suppression pool water level above 723 feet, drywell and suppression pool sprays are not permitted with the vacuum breakers submerged and venting from the suppression pool is not permitted. Therefore, with containment pressure approaching the PCPL curve and above RPV Blowdown requirements, the US should direct LGA-006 for an RPV Blowdown during an ATWS and emergency vent the drywell per LGA-VQ-102.

C) Incorrect. Plausible as LGA-003 would have directed suppression pool and drywell sprays to address high pressure conditions if suppression pool level was < 722 feet. In addition, the suppression pool is the normal first choice for venting to maximize scrubbing of radioactive particulates.

D) Incorrect. Plausible as LGA-003 would have directed suppression pool and drywell sprays to address high pressure conditions if suppression pool level was < 722 feet. The second half is correct.

K/A Statement: Ability to determine and/or interpret the following as they apply to loss of main condenser vacuum: Reactor power.

Proposed Question: Question #83 Unit 1 was at 24% RTP:

  • Reactor power reduced to 20% RTP As a result:
  • Condenser vacuum degraded to 10 inches backpressure and is now STABLE (1) What is the expected automatic plant response with NO operator action?

(2) What procedure MUST be implemented to address the automatic plant response?

A. (1) Reactor power will be greater than 20% RTP (2) LGP-3-2, Reactor SCRAM B. (1) Reactor scram (2) LGP-3-2, Reactor SCRAM C. (1) Reactor power will be greater than 20% RTP (2) LOA-TG-101, Unit 1 Turbine Generator D. (1) Reactor scram (2) LOA-TG-101, Unit 1 Turbine Generator

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __C__

Explanation:

With condenser vacuum at 10 backpressure and stable, the turbine will automatically trip. At 20% RTP, the reactor will not scram when the turbine trips. The TDRFPs trip at 17 Hg, so they will not trip. With the turbine tripped, there will be a loss of feedwater heating, and therefore cold feedwater is being injected into the RPV, causing power to rise. Therefore, the crew will enter LOA-TG-101. The alarm response manual LOR-1PM03J-B511 directs a reactor scram IAW LGP-3-2 based on the low vacuum and LOA-TG-101 also directs a reactor trip if the turbine trips and power is not stable.

A) Incorrect. Plausible because the first part of the distractor is correct. The second part of the distractor is plausible if the applicant believes the condenser vacuum has lowered to the point where the turbine tripped and resulted in a reactor scram and bypass valves opened and maintained power above 20%.

B) Incorrect. Plausible if the applicant believes reactor power is at the level where a turbine trip causes a reactor scram, and that condenser vacuum is low enough to cause the TDRFPs to trip.

C) Correct. When the turbine trips and the reactor does not scram, there is a loss of feedwater heating due to the loss of extraction steam to the feedwater heaters. With the loss of feedwater heating, cold feedwater is added to the RPV, causing a positive reactivity addition.

The crew will implement LOA-TG-101 for the turbine trip.

D) Incorrect. Plausible if the applicant believes reactor power is at the level where a turbine trip causes a reactor scram. The second part of the distractor is correct.

K/A Statement: Ability to interpret control room indications to verify the status and operation of a system, and understand how operator actions and directives, affect plant and system conditions.

Proposed Question: Question 84 Unit 1 is at 100% RTP, with the 1B VP Chill Water Pump OOS, when the following occurred:

  • The crew commenced venting per LGA-VQ-101, "Containment Vent" 20 minutes later Primary Containment Pressure High alarm CLEARED.

  • Drywell pressure is 0.6 psig and SLOWLY RISING What action(s) will the Unit Supervisor direct NEXT?

A. Secure the LGA-VQ-101 containment venting line up and perform LGP-3-2, Reactor SCRAM B. Continue venting per LGA-VQ-101 Containment Vent, cycling of the containment high pressure alarm is an expected response C. Continue venting per LGA-VQ-101 Containment Vent and have chemistry sample the Primary Containment D. Secure the LGA-VQ-101 containment venting line up and have Chemistry sample the Primary Containment

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___A___

Explanation:

A) Correct. The ability to interpret control room indications to verify the status and operation of a system occurs when the primary containment high pressure alarm comes in a second time. This trend is not consistent with the heat up of the containment without a primary containment chiller. The candidate has to understand this change of alarm status to choose the correct answer. When the Hi rad alarms and containment pressure alarm comes in, a change in drywell parameters has occurred. The correct action is to secure the venting, because LGA-VQ-101 does not allow this operation if a Station Vent Stack WRGM Rad Hi alarm is received. Without a running loop of primary containment ventilation and evidence of a leak the next correct action is to scram the unit is the appropriate action. The unit will scram due to the pressure rise in the containment with no remedial actions.

B) Incorrect. Plausible distractor if candidate believes LGA-VQ-01 has similar allowances for venting as LGA-VQ-02 EMERGENCY CONTAINMENT VENT. This LGA-VQ-02 is performed further down the pressure leg of LGA-003 Primary Containment Control after 1.93 psig is exceeded in the drywell.

C) Incorrect. Plausible distractor by securing the LGA-VQ-01 lineup but is incorrect because Chemistry sampling is NOT the first action the crew is to perform.

D) Incorrect. Plausible distractor if candidate believes LGA-VQ-01 has similar allowances for venting as LGA-VQ-02. This LGA is performed further down the pressure leg of LGA-003 Primary Containment Control and does not limit operation based on 1PL75J/1PL15J hi rad alarms. Chemistry sampling the drywell is directed by the LOR actions but this NOT the first actions the crew is to perform.

K/A Statement: Ability to determine and/or interpret the following as they apply to high secondary containment area radiation levels: Cause of high area radiation Proposed Question: Question #85 Unit 1 was at 100% RTP when a LOCA occurs:

  • HCVS is NOT available
  • LGA-VQ-102, Unit 1 Emergency Containment Vent is in progress using Standby Gas Treatment (VG)
  • Drywell pressure is 45 psig and slowly LOWERING
  • Rx Bldg Standby Gas ARM is in alarm
  • Turb Bldg Off Gas Equip and Sample Station ARM is in alarm The radiation alarms are due to (1) and ODCM samples are (2) PRIOR to venting.

A. (1) leakage on a MSL outside of containment (2) required Question 85 was DELETED from B. (1) leakage on a MSL outside of containment the exam due to an operationally (2) NOT required invalid condition in the stem (VG is not able to emergency ventilate C. (1) venting the containment at elevated pressure primary containment under high (2) required pressure conditions).

D. (1) venting the containment at elevated pressure (2) NOT required

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __D__

Explanation: A LOCA has caused high containment pressure and LGA-003 directs the crew to emergency vent the containment IAW LGA-VQ-102. In LGA-VQ-102, the ALARA Precaution on page 18 states that venting containment at elevated pressure using VQ or VG may cause a steam release into the secondary containment, and a steam release into the turbine building through the blowout panels in the MSL tunnel. The MSL tunnel high temperature alarm indicates that a steam release has occurred due to venting, and the corresponding turbine building area radiation alarm indicates the steam leak is into the turbine building through the MSL blowout panels. Discussion #7 in LGA-VQ-102 states that ODCM samples are never required when venting to stay below 60 psig (PCPL) because there is no limit on radiation release.

A) Incorrect. Plausible because leakage on a MSL during an accident will cause the MSL tunnel high temperature alarm and possibly the turbine building area radiation alarms, but it will not cause the area radiation alarms in the reactor building. The second part of the distractor is also plausible because prior to venting, ODCM samples are usually required. In this case, venting is done to preserve the containment, and ODCM samples are not required.

B) Incorrect. Plausible because leakage on a MSL during an accident will cause the MSL tunnel high temperature alarm and possibly the turbine building area radiation alarms, but it will not cause the area radiation alarms in the reactor building. The second part of the distractor is correct.

C) Incorrect. Plausible because the first part of the distractor is correct. Venting containment using VG at elevated pressure will cause reactor building area radiation alarm, and the steam condition introduced due to elevated pressure will cause a steam release through the MSL blowout panels, giving the turbine building area radiation alarm. The second part of the distractor is also plausible because prior to venting, ODCM samples are usually required. In this case, venting is done to preserve the containment, and ODCM samples are not required.

D) Correct. Venting containment using VG at elevated pressure will cause reactor building area radiation alarm, and the steam condition introduced due to elevated pressure will cause a steam release through the MSL blowout panels, giving the turbine building area radiation alarm. When venting to keep pressure below 60 psig, ODCM samples are not required.

SRO Justification: 10 CFR 55.43(b)(4)

Radiation hazards that may arise during normal and abnormal situations. The SRO is responsible for knowledge of the radiation hazards that may be present in the plant due to venting the containment at elevated pressure. While venting containment at elevated pressure due to a severe accident, radiation hazards may exist in the reactor building and turbine building. Despite there being radiation hazards in the plant and the possibility of an offsite release, the SRO is also required to know the ODCM sampling requirements during this situation. The SRO must know that maintaining the containment fission product barrier takes precedence over sampling during a release due to venting the containment at elevated pressure. and prioritize maintaining the integrity of the containment.

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___D___

Explanation:

A) Incorrect. Plausible as this is the correct TS Action statement for one required ADS valves inoperable but since the RPV pressure is less than 150 psig it is not applicable. Only 6 of A7 ADS valves are required to be operable. Therefore, this would be correct if RPV pressure was 150 psig.

B) Incorrect. As ADS is not required with the RPV below 150 psig the first answer is correct.

While there is a surveillance requirement (3.5.1.4) to have the ADS Backup Bottle pressure greater than 500 psig this LCO is not applicable with RPV pressure < 150 psig.

C) Incorrect. Plausible as there is a TS Surveillance Requirement (3.5.1.4) to have the ADS Accumulator Reserve bottle pressure greater than 1100 psig. But it is not applicable with the RPV pressure below 150 psig.

D) Correct. The Technical Specification Bases for TS 3.5.1, Applicability states, in part, In Modes 2 and 3, the ADS function is not required when pressure is less than 150 psig because the low pressure ECCS subsystems (LPCS and LPCI) are capable of providing flow into the RPC below this pressure.

K/A Statement: Ability to (a) predict the impacts of the following on the safety relief valves and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations: Stuck open vacuum breakers.

Proposed Question: Question #87 Unit 1 was operating at 100% RTP when the reactor was scrammed due to a loss of condenser vacuum.

  • RPV pressure is 950 psig and being MANUALLY controlled by SRVs
  • RPV level is being maintained between Level 2 and Level 8 with RCIC in AUTO

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __A__

Explanation: Unit 1 was scrammed due to a loss of condenser vacuum, so the condenser is unavailable for heat removal. Pressure is being controlled by SRVs and level is being controlled by RCIC. With SRV F open, the suppression pool parameters are expected to be rising.

Instead, the drywell parameters are rising due to a stuck open vacuum breaker, which releases steam directly into the drywell through the SRV. The US will direct the crew to close the SRV and enter LGA-003 for drywell pressure and temperature. In this EOP, criteria is met to start drywell cooling IAW LGA-RH-103, but not for drywell spray.

A) Correct. Drywell temperature and pressure are rising due to the stuck open vacuum breaker on the open SRV. IAW LGA-003, the US will direct the crew to start drywell cooling IAW LGA-RH-103 based on drywell temperature being above 135 deg F.

B) Incorrect. Plausible because a break on the RCIC discharge piping would cause the drywell indications, but the given conditions indicate RCIC is running normally and maintaining RPV level. The procedures in the second part of the distractor are correct, but since RCIC is running normal, there is no need to secure RCIC.

C) Incorrect. The first part of the distractor is correct. The second part is plausible because the crew will enter LGA-003 due to high drywell pressure and temperature. When the US directs the crew to shut SRV F, drywell pressure will not continue to rapidly increase and will not reach 12 psig. Therefore, drywell spray is not required. The drywell is greater than 135 deg F so drywell cooling will be initiated IAW LGA-RH-103.

D) Incorrect. Plausible because a break on the RCIC discharge piping would cause the drywell indications, but the given conditions indicate RCIC is running normally and maintaining RPV level. For the second part of the distractor, starting drywell cooling is correct, but the criteria is not met to start drywell spray and since RCIC is running normal, there is no need to secure RCIC.

  • The Outside EO reports that SAT 142 Winding Temperature is 125oC and RISING
  • SAT 142 oil temperature is 115oC with an upper limit of 110 oC
  • All fans and pumps are verified operating
  • The UAT is operating NORMALLY The SRO MUST direct the crew to enter LOA-TRAN-101 and:

A. Perform thermography or other methods to validate the oil temperature and SCRAM the reactor if greater than 110 oC B. SCRAM if greater than 140oC Hot Spot for 30 minutes C. SCRAM the reactor per LGP-3-2, trip the Turbine Generator, and immediately remove SAT 142 from service D. Transfer loads and remove SAT 142 from service

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___D___

Explanation:

A) Incorrect. Plausible as LOA-TRAN-101 does direct to attempt to verify the accuracy of the top oil temperature gauge using thermography or other methods but the verification must be performed PRIOR to reaching 110 C not prior to 30 minutes after reaching 110 C. Scram the reactor only for high temperatures on the UAT not the SAT.

B) Incorrect. Plausible as LOA-TRAN-101 directs a manual SCRAM if a Main Power Transformer is greater than 140 C for 30 minutes. There is no mention of a rapid reactor shutdown in LOA-TRAN-101 for these conditions.

C) Incorrect. Plausible as LOA-TRAN-101, Step B.4.4, RNO directs the reactor be SCRAMMED and Trip the TG if the oil temperature is above 110 C for UAT 141. For SAT 142 it only directs that the transformer be immediately removed from service.

D) Correct. Annunciator for SAT Trouble directs the dispatch of an operator to check transformer parameters locally and refers the operators to LOA-TRAN-101. Step B.4.2 directs to check all fans and pumps running. Step B.4.4 RNO, for oil temperature less than 110 C, directs that SAT 142 Transformer be immediately removed from service.

(1) between the Reactor Pressure Vessel and Core Shroud (2) declare the system inoperable and IMMEDIATELY enter LCO 3.0.3

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __C__

Explanation: The given information indicates there is a LPCS line break/leak. The US dispatched the operator to verify the indication was consistent with the alarm, and dispatched IMD to verify the indication was calibrated correctly. The location of the leak is between the shroud and RPV. Taking the required TRM actions and performing an operability determination will place the Unit in the correct mode of operation to control and mitigate the consequences of the line break.

A) Incorrect. Plausible because the second part of the question is correct, the operability of the affected ECCS system should be evaluated for Operability to determine if the system is still capable of performing its specified function assumed in the safety analysis. The first part of the distractor is incorrect since cooling water would flow out of the break between the RPV wall and shroud and bypass the core region.

B) Incorrect. The second part of the distractor is plausible because a leak may indicated that LPCS cannot perform its design function, but this cannot be determined on the given indication. Per TRM 3.3.f Bases, an Operability determination is to be made to determine system operability. The first part of the distractor is incorrect since cooling water would flow out of the break between the RPV wall and shroud and bypass the core region.

C) Correct. Per TRM 3.3.f Bases, the function of the ECCS header Differential Pressure Instrumentation is to provide an alarm to alert the Operator of a potential compromise of ECCS piping integrity internal to the RPV. The presence of this alarm may indicate that the system is not operable since cooling water would flow out of the break and bypass the core region, potentially invalidating the flow delivery assumptions in the safety analysis. If the alarm is determined to be valid, the operability of the affected ECCS system should be evaluated for Operability to determine if the system is still capable of performing its specified function assumed in the safety analysis.

D) Incorrect. Plausible because the first part of the distractor is correct, since cooling water would flow out of the break and bypass the core region, but the second part is incorrect per basis an Operability determination is made to determine system operability.

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___B___

Explanation:

A) Incorrect. Plausible, starting the Unit 1A and Unit 0 DGs in accordance with SR 3.8.1.2 TS 3.8.1, Action C.3.2 is correct but those are not the only required operable DG which must have SR 3.8.1.2 performed.

B) Correct. TS 3.8.1, Action C.3.1 requires that the operable DGs be determined that they are not inoperable due to a common cause failure within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

K/A Statement: Ability to (a) predict the impacts of the following on RECIRCULATION FLOW CONTROL SYSTEM and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations: Loss of feedwater signal inputs.

Proposed Question: Question #91 Unit 2 is at 68% RTP:

  • The 2A Recirculation FCV was LOCKED due to drifting OPEN.
  • As a result
  • 2A FCV position was 42%
  • 2B FCV position was 38%

Unit 2 stabilized at 70% when the following conditions then occurred:

  • Bearing oil pressure for the 2A TDRFP indicates 3.5 psig and LOWERING
  • Bearing oil pressure for the 2B TDRFP indicates 20 psig and STABLE
  • RPV level is 31 inches and SLOWLY LOWERING
  • The crew has entered LOA-RR-201, Unit 2, Reactor Recirculation System Abnormal (1) How will the plant respond?

(2) What LCO is required to be entered?

A. (1) Reactor level will lower to level 3 requiring a manual scram IAW LGP-3-2 (2) LCO 3.4.2 Condition A for the 2A Recirculation FCV inoperable B. (1) 2B FCV will runback maintaining the plant operating and requiring the crew to trip 2B RR pump within ONE hour (2) LCO 3.4.2 Condition A for the 2A Recirculation FCV inoperable C. (1) Reactor level will lower to level 3 requiring a manual scram IAW LGP-3-2 (2) LCO 3.4.1 Condition B for recirculation flow mismatch not within TS limits D. (1) 2B FCV will runback maintaining the plant operating and requiring the crew to trip 2B RR pump within ONE hour (2) LCO 3.4.1 Condition B for recirculation flow mismatch not within TS limits

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __D__

Explanation: This question matches the K/A because with the trip of the 2A TDRFP, there is a loss of feed input signals from the 2A TDRFP (Lesson Plan 023 p. 33). With the MDRFP OOS, and a trip of the 2A TDRFP due to low bearing oil pressure, steam flow will be higher than feed flow due to the lost feed signal inputs from the feed pump trip. Under these conditions, RPV level will lower, and a recirculation runback will occur once RPV level reaches Level 4 (31.5) and lowering. With one recirc FCV locked and a runback in progress, the crew will have entered LOA-RR-201. With one FCV locked in the open position, and the other FCV closing due to the runback, there will be a flow mismatch, and the steps in the AOP have the US direct the crew to rapidly reduce power and downshift both RR pumps to slow speed IAW LGP-3-1 and for the US to enter LCO 3.4.1.B for one recirculation loop inoperable due to the flow mismatch.

A) Incorrect. The first part of the distractor is plausible because the loss of lube oil to the A TDRFP will cause it to trip and will cause level to lower until steam flow and feed flow match.

The crew will be in the AOP due to the locked FCV and flow mismatch during the runback.

The second part of the distractor is plausible because this is the correct LCO to enter if the FCV was determined to be inoperable. However, per the TS Basis, a locked FCV is in the accident analysis position and is not considered to be inoperable.

B) Incorrect. Plausible because the first part of the distractor is correct. The second part of the distractor is plausible because this is the correct LCO to enter if the FCV was determined to be inoperable. However, per the TS Basis, a locked FCV is in the accident analysis position and is not considered to be inoperable.

C) Incorrect. The first part of the distractor is plausible because the loss of lube oil to the A TDRFP will cause it to trip and will cause level to lower until steam flow and feed flow match.

The crew will be in the AOP due to the locked FCV and flow mismatch during the runback.

The second part of the distractor is correct.

D) Correct. With a reactor low level alarm in and insufficient feedwater pumps operating, a RR runback will occur. IAW LOA-RR-201, the crew will trip the low-flow RR pump per GE SIL 621 within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> due to the flow mismatch caused by the runback with a locked FCV. Due to the flow mismatch, the US will enter LCO 3.4.1.B and declare one recirculation loop inoperable.

SRO Justification:

10 CFR 55.43(b)(2) - Facility operating limitations in the technical specifications and their bases. The SRO applicant is required to know that a recirculation flow mismatch due to a recirculation system runback with one locked recirculation FCV will require entry into the LCO and require one recirculation loop to be inoperable. This is done in order to protect the jet pumps due to the flow mismatch.

10 CFR 55.43(b)(5) - Assessment of facility conditions and selection of appropriate procedures during normal, abnormal, and emergency situations. The SRO applicant is required to assess that a locked FCV and a tripped TDRFP will result in the conditions being satisfied for a reactor recirculation runback. This requires the SRO to correctly select LOA-RR-201, which the applicant will use to direct the crew to perform a rapid power reduction and downshift both RR pumps IAW LGP-3-1. The selection of these appropriate procedures will mitigate the impacts of the loss of FW signal inputs which resulted in the runback and flow mismatch.

Proposed Question: Question 92 Unit 1 is at 100% RTP:

  • A seismic event has occurred, resulting in a leak from the Suppression Pool
  • Suppression Pool water level reads -2 feet and slowly LOWERING on 1LI-CM032, Suppression Pool Water Level Wide Range Indication Subsequently,
  • Suppression Pool temperature reads 106oF and fluctuating on 1TR-CM038A, Div 2 Average Suppression Pool Temperature Recorder

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: ___D___

Explanation:

A) Incorrect. Plausible following a seismic event which has adversely affected the plant. Since Suppression Pool level has dropped by 2 feet, the 28 RTDs which are reporting the high temperature in the suppression pool are now uncovered and no longer reading a valid temperature. If the temperature were valid, and temperature in the Suppression Pool exceeded 105F, then T 3.6.2.1 would be required to be entered.

B) Incorrect. Plausible as the PAM TS should be entered when both RTDs in a well are inoperable.

C) Incorrect. Plausible as level in the Suppression Pool has lowered below the RTDs and therefore their signal is invalid. With a valid reading, then TS 3.6.2.1 would be required to be entered.

D) Correct. Suppression Pool level has lowered below the RTDs making the SP temperature reading/alarm invalid. When both RTDs in a well are inoperable, with the plant still in Mode 1, TS 3.3.3.1 is applicable for Function 9.

K/A Statement: Ability to (a) predict the impacts of the following on the CONTROL ROOM HVAC and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations: Extreme environmental conditions.

Proposed Question: Question #93 Unit 1 was operating at 100% RTP:

  • Radiation Protection has informed the Unit Supervisor that the alarm is VALID, and the ammonia concentration in the Control Room is 20 ppm
  • Control Room HVAC system is in its normal flow path alignment The Control Room HVAC system (1) to recirculation mode, and the Unit Supervisor will direct (2) .

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __A__

Explanation: This question meets the K/A because high concentrations of ammonia can be immediately dangerous to life and health (IDLH), and ammonia concentrations are detected in the outside environment at the outside air intakes. On this extreme environmental condition, an alarm will be received, and the crew must manually align the CR HVAC to recirculation mode for Control Room habitability. The SRO must know when to direct a Control Room evacuation and when the crew must don SCBAs based on the measured ammonia concentration. At the given concentration, the SRO will direct the crew to don SCBAs and the evacuation of all unnecessary personnel from the Control Room.

A) Correct. Only an alarm will be received for high ammonia, and the crew must then manually align the CR HVAC to recirculation mode. To protect the crew and plant personnel, the US will direct the Control Room crew to don SCBAs and will evacuate all unnecessary personnel from the Control Room.

B) Incorrect. The first part of the distractor is plausible because the CR HVAC will automatically align to a different mode (pressurization mode) on high outside radiation levels, but there is no automatic action for ammonia levels. The second part of the distractor is plausible because ammonia is dangerous to health at levels above 25 ppm and will direct the evacuation of the Control Room at higher levels, especially when levels reach levels IDLH.

C) Incorrect. The first part of the distractor is correct. The second part of the distractor is plausible because ammonia is dangerous to health at levels above 25 ppm and will direct the evacuation of the Control Room at higher levels, especially when levels reach levels IDLH.

D) Incorrect. The first part of the distractor is plausible because the CR HVAC will automatically align to a different mode (pressurization mode) on high outside radiation levels, but there is no automatic action for ammonia levels. The second part of the distractor is correct.

To prevent entry into the applicable LCO, the B APRM Channel Check MUST be performed .

A. immediately B. by 1600 on the same day C. by 1900 on the same day D. by 0400 on the next day

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __D__

Explanation: This question examines the SRO applicants ability to perform and meet the requirements of integrated surveillance procedures, as well as their ability to adhere to the TS surveillance requirements. The question is Tier 3 because it does not require specific knowledge of a system or knowledge of a specific LCO, but instead how to follow the requirements of a station surveillance procedure and the requirements in SR 3.0.2 and SR 3.0.3 in the TS.

SR 3.0.3 states that when it is discovered that a surveillance has not been performed within its specified frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified frequency, whichever is greater. Therefore, since the specified frequency for a channel check of the APRMs is 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, the crew has 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from the time of discovery to complete the channel check. SR 3.3.1.1.1 states the surveillance frequency for a channel check is in accordance with the Surveillance Frequency Control Program. Section 5.0 of the TS states the provisions of SR 3.0.2 and 3.0.3 still apply.

A) Incorrect. Plausible because it was discovered that the surveillance has not been met for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, which exceeds the surveillance requirement of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. It is logical to conclude the surveillance interval was missed and therefore must be performed immediately.

B) Incorrect. Plausible because SR 3.0.3 states entry into the LCO may be delayed up to the limit of the specified frequency, which is 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and would give you time 1600 on the same day, or up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, whichever is greater. Therefore, the crew has up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

C) Incorrect. Plausible because SR 3.0.2 gives a grace period of 1.25x the surveillance interval. For shiftly surveillances, that would be 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />. The time of 1900 on the same day is 15 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br />. However, the conditions state that the surveillance has not been performed in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, so SR 3.0.2 does not apply, and the SR 3.0.3 would instead be used to give the crew 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> from the time of discovery to complete the surveillance before the LCO must be entered.

D) Correct. Using SR 3.0.3, for a missed surveillance, the crew has 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to complete the surveillance from the time of discovery before the LCO must be entered.

K/A Statement: Knowledge of pre and post-maintenance operability requirements.

Proposed Question: Question #97 Unit 1 is at 8% RTP with the Mode Switch in START-UP.

An outboard containment isolation valve that is required to be OPERABLE in Modes 1, 2, and 3, FAILED its stroke time testing. To comply with LCO TS 3.6.1.3 Primary Containment Isolation Valves, the inoperable valve has been closed and deactivated.

After 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, maintenance has been completed and Post Maintenance Testing (PMT) requires the valve to be opened and timed closed.

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __C__

Explanation: This is a Tier 3 question because it does not require knowledge of the containment isolation valves, only usage of the LCOs applicable to PMT. For PMT, the applicable section of the TS is LCO 3.0.5. According to LCO 3.0.5, equipment removed from service or declared inoperable to comply with actions may be returned to service under administrative control solely to perform testing required to demonstrate operability or the operability of other equipment. This is an exception to LCO 3.0.2 for the system returned to service under administrative control to perform the testing required to demonstrate operability. It is important to note that LCO 3.0.5 shall not be entered to administratively return the equipment to service in order to troubleshoot and perform additional maintenance.

A) Incorrect. Plausible if the applicant believes the testing should be performed in a lower mode (Mode 3 or 4). Entering LCO 3.0.3 will take the plant to Mode 3 and then to Mode 4.

Also plausible if the applicant believes the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> time to repair the valve has exceeded the LCO 3.6.1.3 limits and an entry into LCO 3.0.3 is warranted.

B) Incorrect. Plausible because the plant is in the middle of a startup, and LCO 3.0.4 applies to transitioning between Modes. It is plausible that the applicant may believe the plant should not enter Mode 1 prior to completing the PMT, and therefore LCO 3.0.4 should be entered.

C) Correct. LCO 3.0.5 is the applicable LCO section, as it states equipment that is inoperable may be returned to service in order to demonstrate operability.

D) Incorrect. Plausible because the applicable LCO requires an inoperable valve to be closed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Performing stroke timing then re-closing the valve is considered to be troubleshooting and it is not permitted to re-enter the action statement of an applicable LCO unless using administrative controls under LCO 3.0.5.

K/A Statement: Knowledge of the organization of the operating procedures network for normal, abnormal, and emergency evolutions Proposed Question: Question #99 At 0700, Unit 2 experienced a Station Blackout.

At 0715, the Shift Manager declared an extended loss of AC power (ELAP) on Unit 2. The crew began implementing LOA-AP-201 Attachment N, DC Load Shedding.

At 0730, an entry condition was met for LGA-002, Secondary Containment Control.

Which of the following will the Unit Supervisor direct the crew to perform?

A. COMPLETE the actions of LOA-AP-201 Attachment N, DC Load Shedding, THEN enter LGA-002, Secondary Containment Control.

B. Perform LOA-AP-201 Attachment N, DC Load Shedding IN PARALLEL with LGA-002, Secondary Containment Control.

C. EXIT LOA-AP-201 Attachment N, DC Load Shedding, THEN enter LGA-002, Secondary Containment Control.

D. SUSPEND actions of LOA-AP-201 Attachment N, DC Load Shedding, COMPLETE the actions of LGA-002, Secondary Containment Control, THEN resume LOA-AP-201 Attachment N, DC Load Shedding.

ES-401 Written Examination Form ES-401-5 Question Worksheet Proposed Answer: __B__

Explanation:

This is a Tier 3 question because it does not require knowledge of the AC power system, SBO contingencies, or Load Shedding procedure to answer. It is testing LaSalles organization of AOPs and EOPs and the correct way to utilize these procedures to mitigate an accident.

Therefore, this is not an extension of Tier 1 or Tier 2. The US is not required to diagnose the event but is required to have knowledge of the correct priority of procedure usage.

There are some instances where an AOP is exited when EOP entry conditions are met, and some instances where the AOP must be performed in parallel. The SRO must have general knowledge of the procedure organization and which procedures have time critical actions.

Therefore, the crew will not exit the AOP and will perform the AOP in parallel with the EOP.

A) Incorrect. Plausible because the crew will continue in LOA-AP-201 Att. N, but must also work in parallel to address the entry conditions in LGA-002.

B) Correct. DC Load Shedding is a time critical operator action during an ELAP, and the crew will continue to perform these actions while performing the actions in LGA-002.

C) Incorrect. Plausible as this is the case where there are no time critical actions to be performed in the AOP and/or the EOP will address all of the conditions for which the AOP was entered. Since DC Load Shedding is time critical, the procedures will be worked in parallel.

D) Incorrect. Plausible as AOPs are suspended where there are not time critical actions to be performed in the AOP and/or the EOP will address all of the conditions for which the AOP was entered. However, the crew will not suspend the DC load shedding actions, then resume them when the actions of LGA-002 are complete. DC load shedding is time critical and will be performed in parallel with LGA-002.
