Energizing a faulted bus Verify there are no faults on the Bus AND Place Bus 101 Synchronizing Switch to On Answer: D 47

Nine Mile Point Unit 2 2010 NRC RO Written Examination Explanation (Optional):

A: Incorrect: without an ECCS signal none of the large loads have closed on the bus therefore there is NOT a danger of overloading EG 1, therefore there is no requirement in SOP-3 to place large loads in PTL. Procedurally, the synch switch is required to be on prior to closing the diesel output breaker.

B: Incorrect: Procedurally, the synch switch is required to be on prior to closing the diesel output breaker.

C: Incorrect: without an ECCS signal none of the large loads have closed on the bus therefore there is NOT a danger of overloading EG 1, therefore there is no requirement in SOP-3 to place large loads in PTL.

D: Correct: A potential fault on 2ENS*SWG101 would prevent EG 1 from automatically closing on the bus. SOP-3 requires the operator to verify the bus is not faulted by verifying the bus fault annunciators (852147 and 852148) are clear. With EG 1 already running the procedure directs placing the Synch Switch in on and then manually closing the breaker.

Fuel Pool Temperature To Re-establish Temperature Control A. Lowers Manually close the FilterlDemin Bypass Valve, 2SFC-HIC113 only.

B. Rises Wait 60 seconds then restart the Fuel Pool Cooling Pump only.

C. Lowers Manually close the Filter/Demin Bypass Valve, 2SFC-HIC113 and place the Filter Demins back in service.

D. Rises Wait 60 seconds then restart the Fuel Pool Cooling Pump and line up Service Water Backup Cooling to the SFC heat exchanger.

Answer: D Explanation (Optional):

A: Incorrect. Fuel Pool temperature rises because the SFP pumps trip on a LOOPILOCA and must be manually restarted. Filter/Demin Bypass Valve, 2SFC-HIC113 initially fails closed on a momentary loss of power. The valve will then return to its normal position 65

Nine Mile Point Unit 2 2010 NRC RO Written Examination because this valve is always controlled in manual.

B: Incorrect: To re-establish cooling Service Water Backup Cooling must be line-up.

C: Incorrect: Fuel Pool temperature rises because the SFP pumps trip on a LOOP/LOCA and must be manually restarted. FilterlDemin Bypass Valve, 2SFC-HIC113 initially fails closed on a momentary loss of power. The valve will then return to its normal position because this valve is always controlled in manual. PlaCing the filter/demins in service will not effect fuel pool cooling temperatures.

D: Correct: On a Loss Of Coolant Accident (LOCA), the running Pump will continue to run but a Pump cannot be started or restarted during the first 60 seconds after receipt of the LOCA signal. If a Loss of Offsite Power (LOOP) and a LOCA occur simultaneously, the running Pumps will trip. A Pump may be manually restarted after 60 seconds using N2 SOP-03. The Reactor Building Closed Loop Cooling Water supply to the SFC Heat Exchanger is also lost on a LOOP/LOCA and Service Water Backup Cooling to the SFC Heat Exchanger must be manually lined up by the operator.

Inadequate Recirc Pump NPSH Manually trip the CIA" Recirc pump after a scram if the reactor scrams Answer: A Explanation (Optional):

A: Correct: Per precaution # 25 in OP-29, flow forces on the valve cause the FCV to drift close. If the Hydraulic Power Supply is to be shutdown at power at the discretion of the 67

Nine Mile Point Unit 2 2010 NRC RO Written Examination SM, close the appropriate loop outside hydraulic isolation valve by taking the LOOP A(B) HYDR FLUID OUTSIDE ISOL switch to the CLOSE position.

B: Incorrect: Per precaution # 25 in N2-0P-29, flow forces on the valve cause the FCV to drift close NOT open therefore reactor power would lower.

C: Incorrect: Flow mismatch is not concern after the scram, additionally both pumps will shift to low speed after the scram.

D: Incorrect: A reactor scram will cause the pump to shift to slow speed. Adequate NPSH will still be maintained due to the height of the water inside the vessel. (page 26 of Facility Recirc Lesson Plan) Plausible in that the required NPSH is a function of flow through the pump. Following a scram the reduced feed flow lowers the available NPSH.

74

Nine Mile Point Unit 2 2010 NRC RO Written Examination Answer: D Explanation (Optional):

A: Incorrect - RBM "A" is provided a backup signal from APRMs 3 & 4.

B: Incorrect - RBM "B" is provided a backup signal from APRMs 3 & 4.

C: Incorrect - selection of any other control rod will renormalize the RBM.

D: Correct - lAW N2-0P-92, Page 7 system description - The APRM provides Simulated Thermal Power to the RBM which uses that power level to determine which RBM power range setpoint is enabled. RBM A receives a signal from APRM 1 (APRM 3 and then 4 are alternates). RBM B receives a signal from APRM 2 (APRM 4 and then 3 are alternates) .

The RBM is calibrated to a fixed (constant) reference each time a non-peripheral rod is selected. At the time of rod selection the RBM takes input from the surrounding LPRMs at various core heights and averages these readings. A "nulling" operation is performed which establishes the pre-rod motion value. This value is normalized to 100%.

Renormalization is allowed by deselecting and reselecting the rod.

Which one of the following failures I actions could result in exceeding the Primary Containment Pressure Limit (PCPL) and subsequent containment failure?

A. Initiating Drywell sprays with Suppression Pool level above 217 feet.

B. One set of Suppression Chamber to Drywell vacuum breakers failing closed.

C. Initiating Drywell sprays when outside the limits of the Drywell Spray Initiating Limit.

D. A break in a drywell to Suppression Chamber downcomer above the level in the Suppression Pool.

Answer: D Explanation (Optional):

A: Incorrect -Initiating drywell spray at this level might challenge containment integrity but the failure mechanism would be due to exceeding the negative pressure rating due to the vacuum breakers being covered.

B: Incorrect - Both check valves failing closed would not result in a challenge to the PCPL.

Plausible in that both valves failing open would also result in steam bypass to the suppression chamber and possible challenge to the PCPL.

78

Nine Mile Point Unit 2 2010 NRC RO Written Examination C: Incorrect -Initiating drywell sprays when outside the limits of the Drywell Spray Initiating Limit could result in containment failure but the failure mechanism would be due to exceeding the negative pressure rating.

D: Correct - The PCPL is a high pressure limit based on maintaining containment integrity.

The lowest pressure is 45 psig which is also the design pressure of the containment.

The UFSAR worst-case steam bypass analysis assumes a total bypass leakage path area of less than 0.1 ft2 (primarily drywell floor seams, downcomer and SRV piping penetrations, and vacuum breakers). The bypass path area of a single downcomer (assuming a double-ended rupture) would be almost 30 times larger. Although no specific data exists, NMPC Engineering is certain that the 45 psig primary containment design pressure would be exceeded.

Which one of the following is the EOP bases for performing this action?

This action ...

A. increases the concentration of boron being injected into the core.

B. allows preheating the feedwater to lower the possibility of thermal hydraulic instabilities.

C. reduces the amount of natural circulation in the core following the tripping of the Recirc Pumps.

D. increases the amount of inlet subcooling to further reduce power via the temperature coefficient.

Answer: B Explanation (Optional):

A: Incorrect - These steps were added to C5 to address thermal instabilities. Plausible in that lowering level will reduce the volume of water inside the shroud.

B: Correct: Per EOP bases, 100 inches is 24 inches below the feedwater spargers. When injection is commenced, feedwater will fall though a steam space and be preheated 86

The following conditions exist:

  • Indicated drive flow in the operating Recirculation loop is 21,000 gpm
  • Indicated total core flow on Control Room Panel P603 is 22 Mlbm/hr Which one of the following identifies the current relationship between indicated total core flow on P603 flow recorder and actual total Core Flow and the reason for the difference?

Indicated total core flow is ...

A. higher than actual due to idle loop flow being added to the total core flow summing network.

B. higher than actual due to idle jet pump flow being added to the total core flow summing network.

C. lower than actual due to idle loop flow being subtracted from the total core flow summing network.

D. lower than actual due to idle jet pump reverse flow being subtracted from the total core flow summing network.

Answer: C Explanation (Optional):

103

Nine Mile Point Unit 2 2010 NRC RO Written Examination A: Incorrect - at less than 22 kgpm when one recirculation pump is not running, the forward/reverse flow logic network automatically subtracts the measured flow in the idle loop from the measured flow in the active loop.

B: Incorrect - at less than 22 kgpm when one recirculation pump is not running, the forward/reverse flow logic network automatically subtracts the measured flow in the idle loop from the measured flow in the active loop.

C: Correct - NOTE 2 following Step H.6.0 of N2-0P-29, Reactor Recirculation System, states 'When calculating total core flow in single loop operation and the operating loop drive flow is less than 22,000 gpm, Loop Flows should be added instead of subtracted".

In addition, Step 6.2 & 6.3 of N2-RESP-07, When one recirculation pump is not running, the forward/reverse flow logic network automatically subtracts the measured flow in the idle loop from the measured flow in the active loop and displays the true core flow on the P603 chart recorder (B22-R613) and computer point NSSFA101 (total core flow),

and NSSFA01 S (total core flow - smooth).

If in single loop operation with less than 22,000 GPM flow, flow in the shutdown loop will be positive instead of negative as assumed by the summing network (Step 6.2).

Therefore in this situation, a calculated total core flow must be substituted into computer point NSSFA 101 and NSSFA01 S prior to demanding a core monitoring case.

D: Incorrect - at less than 22 kgpm when one recirculation pump is not running, the forward/reverse flow logic network automatically subtracts the measured flow in the idle loop from the measured flow in the active loop (not jet pump reverse flow Technical Reference(s): N2-RESP-07, section 6.2 and 6.3 (Attach if not previously provided)

Question: RO#55 Which one of the following is the bases for Technical Specifications Iodine 131 limit?

Limits the maximum amount of ...

A. TEDE dose received by an individual at the exclusion area boundary.

B. CEDE dose received by an individual at the exclusion area boundary.

C. TEDE dose received by an individual at the protected area boundary.

D. CEDE dose received by an individual at the protected area boundary.

Answer: A Explanation (Optional):

A: Correct - Per TS 3.4.8 bases - Limits on the maximum allowable level of radioactivity in the reactor coolant are established to ensure, in the event of a release of any radioactive material to the environment during a DBA, radiation doses are maintained within 10% of the limits of 10 CFR 50.67 Per 10 CFR 50.67 - An individual located at any point on the boundary of the exclusion area for any 2-hour period following the onset of the postulated fission product release, would not receive a radiation dose in excess of 0.25 Sv (25 remf total effective dose equivalent (TEDE). 10% of this limit would therefore be 2.5 Rem.

Question: RO#56 The plant was operating at rated conditions with APRM 1 inoperable and bypassed. when the "A" Reactor Recirc pump trips. Following the trip, the following conditions exist:

  • Core flow 40%
  • Reactor power 60%
  • OPRM Trip Enabled status lights are illuminated for OPRM 2 and 3
  • The remaining OPRM status lights are extinguished.
  • CRS has determined that OPRM #4 is INOP.

When the APRM Numac Displays on P608 are checked the message "OPRM TRIP ENABLE" is displayed on OPRM 2 and 3 only. NO other OPRM messages are displayed.

Which one of the following is required by station procedures?

A. Insert the first 4 CRAM rods B. Place the reactor mode switch to Shutdown C. Raise core flow with the "B" Recirculation Pump to exit the Exit Region D. Shift APRM recorders to fast speed AND monitor for core oscillations Answer: B 114

Nine Mile Point Unit 2 2010 NRC RO Written Examination Explanation (Optional):

A: Incorrect: Only 2 OPRMs are available. OPRM 1 is not available due to APRM 1 being bypassed. OPRM 4 failed to enable when power and flow lowered. SOP-29 directs that if Core flow AND power are within the OPRM Dependent Stability Region and less than 3 OPRMs are available then the reactor should be scrammed. Per the single loop power flow map, core conditions are within the OPRM Dependent Stability Region.

Plausible in that this would be the action if at least 3 OPRMs were available.

B: Correct: Per ARP 603218, OPRMs should have enabled. Only 2 of the three available did so. Per SOP-29, if operating in the OPRM Dependent Stability Region and less than 3 are available, the reactor is to be scrammed.

C: Incorrect: The reactor should be scrammed. Plausible in that if the 2 loop power to flow map is used, the reactor is operating in the exit region.

D: Incorrect: The reactor should be scrammed. Plausible in that if in the Heightened awareness region and < 3 OPRMs were available this would be a required action.

  • A small break LOCA is in progress.
  • Appropriate EOPs have been entered.
  • No injection sources are available.
  • RPV level is approaching the TAF.

Which one of the following describes why RPV Slowdown is delayed until water level has lowered to the Minimum Zero-Injection RPV Water Level per N2-EOP-C3?

A. RPV Slowdown before this level reduces the time the core remains adequately cooled during these conditions.

S. Steam Cooling will NOT maintain fuel cladding temperature below 1500°F if blowdown is performed with water level above TAF.

C. RPV Slowdown before this level produces insufficient steam mass removal rate for adequate core cooling.

D. Steam cooling will NOT maintain fuel cladding temperature below 1800°F if blowdown is performed with water level above TAF.

Answer: A Explanation (Optional):

119

Nine Mile Point Unit 2 2010 NRC RO Written Examination A: Correct - Per EOP-C3, (Page 10-14 of EOP Bases Document), it states "opening the SRVs before RPV water level reaches the MZIRWL would reduce the time over which the core remains adequately cooled with no injection".

B: Incorrect - The temperature limit in steam cooling is 1800 degrees. This value is not reached until level has lowered to -58". If the blow down is commenced before TAF, temperature will be well below 1800 degrees. However the time available before adequate core cooling is lost will be reduced since the blowdown was performed before the temperature limit was reached.

C: Incorrect - The concern is time permitted for adequate cooling with no injection and not steam mass removal rate generated heat.

D: Incorrect - -58" is the level at which steam cooling would be unable to preclude clad temperature from reaching 1800 degrees and is the Minimum Zero-Injection RPV Level.

It is not the reason you delay a blowdown. TAF is -14 inches.

Manual insertion capability Scram function A. NOT available Not Degraded B. Available Degraded C. NOT Available Degraded D. Available Not Degraded 121

Nine Mile Point Unit 2 2010 NRC RO Written Examination Answer: C Explanation (Optional):

A: Incorrect - The first half is correct since RMCS is not available; however scram function is not fully assured. See explanation for answer C.

B: Incorrect - The first half is incorrect since RMCS is not available without drive pressure.

The second half is correct since scram function may be degraded. See explanation for answer C.

C: Correct - Per TS Bases 3.1.4 Background - "If the reactor pressure is low, such as during startup, the accumulator will fully insert the control rod within the required time without assistance from reactor pressure." At least 2 withdrawn control rods have low accumulator pressures rendering them inoperable <<940 psig). Rods mayor may not fully insert or they may not insert fast enough under the given conditions, so the scram function may be degraded.

With both CRD pumps off, there is no drive pressure, so manual insertion using RMCS is not possible. Furthermore, CRD charging water pressure is also lost. In addition, reactor pressure is less than 900 psig, so reactor pressure alone may not complete the scram.

D: Incorrect - Both parts of this answer are wrong. See the explanation for answer C.

Direction is given in the EOPs that if SRVs are cycling, to manually open SRVs until pressure drops to 970 psig.

Which of the following describes the basis for this direction?

A. Maintains adequate core cooling in the RPV.

B. Maximizes the amount of steam condensed in the suppression pool.

C. Maximizes the amount of energy directed to the main condenser.

D. Maintains stable reactor parameters to prevent the loss of high pressure feed systems.

Answer: C Explanation (Optional):

A: Incorrect - Directs the most amount energy possible to the main condenser.

B: Incorrect - Directs the most amount energy possible to the main condenser.

C: Correct - Pressure is stabilized at a value below 1052 psig, the high RPV pressure scram setpoint, to avoid SRV actuation and to permit the scram logic to be reset (if no other scram signal exists). SRVs are opened and pressure is reduced to 970 psig to 130

Nine Mile Point Unit 2 2010 NRC RO Written Examination stop them from cycling because this is the pressure at which steam flow through the TBVs is at 100%. This minimizes reactor power swings and maximizes the amount of energy going to the main condenser. Lowering pressure lower than this risks the TBVs going closed. This could then cause the SRVs to reopen and put more energy in the suppression pool.

Incorrect - High pressure feed systems will be secured to lower reactor power.

Question: SRO#76 The plant is operating at rated conditions. You receive notification from System Power Control that area thunderstorms have caused unstable grid conditions. They also inform you that the Load Flow Program is NOT in service.

  • Line 5 voltage on P852 is reading 109 KV
  • Line 6 voltage on P852 is reading 113 KV Which one of the following is required?

A Declare both Line 5 and Line 6 inoperable and assess the condition for reportability.

B. Declare Line 5 inoperable and assess the condition for reportability.

C. Declare both Line 5 and Line 6 inoperable. Reportability is NOT required to be addressed unless a complete loss of Offsite Power occurs.

D. Declare Line 5 inoperable . Reportability is NOT required to be addressed unless a complete loss of Offsite Power occurs.

Answer: B Explanation (Optional):

A: Incorrect: With Line 6 voltage at 113KV, it is not yet inoperable with voltage greater than 110 KV.

B: Correct: lAW SOP-70 Discussion Section 5.3 0- The Load Flow computer at National Grid runs a program that looks at 115 KV voltage for Line 5 and Line 6. This program 1

Nine Mile Point Unit 2 2010 NRC SRO Written Examination determines if there is sufficient voltage (depending on grid loading) to supply NMP 2 ECCS loads during a LOCA (plant trip). If the voltage is too low, a contingency low voltage alarm is received at Power Control. If the contingency low voltage alarm is received OR actual voltage is less than 110 KV with the load Flow computer unavailable, then the offsite power source cannot perform its function under accident conditions and is, therefore, inoperable. The 110 KV value was selected because the actual low voltage value of 109.25 KV cannot be read on the Control Room instrumentation. If the 115 kV voltage lowers to the point where both Line 5 and Line 6 are inoperable, the event may be reportable under 10 CFR 50.72 (b)(3)(v) for an Event or Condition That Could Have Prevented Fulfillment of a Safety Function, based on NUREG 1022, Section 3.2.7.

C: Incorrect: With Line 6 voltage at 113KV, it is not yet inoperable with voltage greater than 110 KV.

D: Incorrect: Reportability must be addressed per the SOP.

Importance Rating 3.6 Ability to determine and/or interpret the following as they apply to PARTIAL OR COMPLETE LOSS OF INSTRUMENT AIR: Instrument air system pressure Question: SRO#77 With the plant operating at rated conditions the following sequence occurs:

  • Scram air header pressure is reported as 59 psig and slowly lowering.
  • Ten seconds later, alarm CONTROL ROD DRIFT, 603443 annunciates. Operators identify that control rod 34-23 has drifted to the fully inserted position.

Which one of the following describes the required actions and the reasons for those actions?

A. Enter N2-S0P-08, Unplanned Power Changes, and direct reactor power be reduced by 40 MWe using recirc flow control. This will improve the margin to thermal limits during potentially unanalyzed rod patterns.

B. Enter N2-S0P-08, Unplanned Power Changes, and monitor for additional rod drifts. If two rods drift direct that the reactor be scrammed. This is necessary to prevent potentially exceeding thermal limits due to crossing blade tips.

C. Enter N2-S0P-19, Loss of Instrument Air, and direct the backup pressure control valve, PCV-19A(B), be placed in service. This is necessary to re-establish normal scram air header pressure to maintain required scram times.

D. Enter N2-S0P-19, Loss of Instrument Air, and direct that the reactor be scrammed.

This is necessary to prevent the development of unanalyzed rod patterns, which could result from rods individually scramming.

Answer: D 3

Nine Mile Point Unit 2 2010 NRC SRO Written Examination Explanation (Optional):

A: Incorrect: The reactor should be scrammed. Plausible in that the Rod Drift ARP directs entry into SOP-OB. SOP-OB also directs power be reduced by 40 MWe for a single rod scram.

B: Incorrect: A scram criteria exists lAW SOP-19. Plausible in that this is the required action in SOP-OB if two rods drift.

C: Incorrect: Plausible in that ARP for CRD SCRAM AIR HEADER PRESSURE HIGH/LOW directs entry into SOP-19. SOP-19, attachment 3 directs shifting PCV valves provided differential pressure across the in-service PCV and filter is >9 psid.

However, the override on the loss of air flowchart requires the scram.

D: Correct: ARP for CRD SCRAM AIR HEADER PRESSURE HIGH/LOW directs entry into SOP-19. SOP-19 directs that a scram be inserted if pressure lowers to less than 60 psig. This is necessary to prevent the development of unanalyzed rod patterns, which could result from rods individually scramming when air pressure is lost to their respective scram valves.

Question: SRO#84 Reactor power is on IRM range 8 with a reactor plant startup in progress when the following sequence of events occurs.

  • Alarm IRM UPSCALE,603207,annunciates
  • The reactor operator reports alliRMs are rising and up ranges IRIVI channels
  • Alarm APRM TRIP SYSTEM UPSCALE, 603208, annunciates
  • Reactor power is reported as 17% and rising
  • The reactor operator places the mode switch to Shutdown
  • The reactor operator reports that all control rods have inserted.

Based on these indications, which one of the following is correct regarding entry into the emergency operating procedures and the emergency plan?

A. Entry into N2-EOP-C5, Failure to Scram is required and a Site Area Emergency is required.

B. Entry into N2-EOP-RPV, RPV Control is required and an Alert Declaration is required.

C. Entry into the EOPs is NOT required but an Alert Declaration is required.

D. Entry into N2-EOP-RPV, RPV Control is required but entry into the Emergency Plan is NOT required.

Answer: B Explanation (Optional):

19

Nine Mile Point Unit 2 2010 NRC SRO Written Examination A: Incorrect: Although RPS failed to trip on the APRMs, entry into as C5 is not required because placing the mode switch to shutdown achieved rod insertion. C5 is only entered from N2-EOP-RPV if manual action to scram is unsuccessful. The SAE is plausible in that it addresses a failure to scram condition but is only exceeded if both auto AND manual circuits fail.

B: Correct: An entry condition to N2-EOP-RPV was exceeded when reactor power exceeded the APRM setpoint scram settings and the reactor did not scram. An alert is required based on EAL 2.2.1. This EAL is exceeded when a RPS scram signal is exceeded and an automatic scram fails to result in a control rod pattern that will achieve reactor shutdown status under all conditions. This occurred when the RPS failed to auto trip when the APRM set point was exceeded.

C: Incorrect: An entry condition to N2-EOP-RPV was exceeded when reactor power exceeded the APRM setpoint scram settings and the reactor did not scram. Plausible in that manual action achieved reactor shutdown and no other indications of an emergency are provided.

D: Incorrect: An alert is required based on EAL 2.2.1. Plausible in that placing the mode switch in shutdown achieved a control rod pattern that will ensure the reactor remains shutdown under all conditions.

Drywell pneumatics has just been restored to the ADS valves when the following indications and reports are received:

  • All seven ADS valves are open
  • Reactor pressure is 180 psig and lowering
  • ADS Header B pressure is 60 psig and lowering
  • All ADS accumulator pressures associated with ADS Header B indicate approximately 170 psig and slowly lowering Given the above conditions:

(1) What is the status of the ADS valves associated with ADS AIR HEADER Band (2) What action should the SRO direct to mitigate the consequences of these indications?

A: (1) ADS valves are open but will eventually close as accumulators depressurize.

(2) If less than 6 SRVs are open, maintain RPV pressure less than 40 psi above Suppression Chamber pressure, in accordance with N2-EOP-C2.

B: (1) ADS valves are cycling between open and close due to low pneumatic pressure.

(2) If less than 6 SRVs are open, maintain RPV pressure less than 40 psi above Suppression Chamber pressure, in accordance with N2-EOP-C2.

26

Nine Mile Point Unit 2 2010 NRC SRO Written Examination C: (1) ADS valves are open but will eventually close as accumulators depressurize.

(2) Direct that ADS Header B and ADS Receiver 2IAS*TK 5 be re-pressurized via Emergency Truck Fill, in accordance with ARP 601515.

D: (1) ADS valves are cycling between open and close due to low pneumatic pressure.

(2) Direct that ADS Header B and ADS Receiver 2IAS*TK 5 be re-pressurized via Emergency Truck Fill, in accordance with ARP 601515.

Answer: A Explanation (Optional):

A: Correct: ADS valves are being held open by their accumulators, as pressure lowers the valves will close and cannot be opened. The pneumatic symptoms provided are indicative of a pneumatic supply line break in the drywell. ADS Air Header B supplies air to ADS valve accumulator tanks TK35, TK36, TK37 AND TK38. The three other ADS valve accumulators are still operable. Additionally the non ADS valves are un effected. lAW N2-EOP-C2, RPV Blowdown with less than 6 SRVs open, maintain RPV pressure less than 40 psig above suppression chamber pressure.

B: Incorrect: ADS valves are being held open by their accumulators.

C: Incorrect: Aligning the Emergency Fill would not restore pressure due to the break inside the drywell.

D: Incorrect: ADS valves are being held open by their accumulators. Aligning the Emergency Fill would not restore pressure due to the break inside the drywell.

Question: SRO #99 The plant is operating at rated conditions with Division III SWGR on Line 6. Offsite line maintenance has resulted in Line 5 being declared inoperable at 12:00 on May 1, 2010.

Given the following:

08:00 on May 3: Div 1 DG is declared INOP.

12:00 on May 3: Line 5 is declared OPERABLE.

16:00 on May 4: Div 3 DG is declared INOP.

14:00 on May 5: Div 1 DG is declared OPERABLE.

06:00 on May 6: Line 5 is declared INOP.

08:00 on May 6: Div 3 DG is declared OPERABLE.

Which one of the following describes correct implementation of Tech Specs for this sequence of events?

A. Entry into REQUIRED ACTION requiring a plant shutdown existed at NO TIME during this sequence of events. Restore line 5 to operable status no later than 06:00 on May 9.

B. Entry into REQUIRED ACTION requiring a plant shutdown existed at NO TIME during this sequence of events. Restore line 5 to operable status no later than 12:00 on May?

C. At 18:00 on May 4, TS 3.8.1, REQUIRED ACTION F.1 was required to be entered but this action was exited as permitted by LCO 3.0.2 before the shutdown was required to be initiated. Restore line 5 to operable status no later than 06:00 on May 9.

53

Nine Mile Point Unit 2 2010 NRC SRO Written Examination D. At 16:00 on May 4, TS 3.8.1 REQUIRED ACTION G.1 was required to be entered and the plant was required to be placed into MODE 3 but this action was not completed. Restore line 5 to operable status no later than 12:00 on May 7.

Answer: B Explanation (Optional):

A: Incorrect - The statement for restoring Line 5 to operable" ..... no later than 06:00 on May 9" is incorrect. This choice is based on Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> which started on 06:00 on May 6, but does not account for the limit imposed by the modified time zero (6 days from discovery of failure to meet the LCO from initial entry into Condition A at 12:00 on May 1). Not applying the modified time zero results in a completion time of 06:00 on May 9 results, which is incorrect.

B: Correct - Correctly applying the modified time zero on initial entry into CONDITION A when Line 5 is declared inoperable at 12:00 on May 1 results in Line 5 restoration with completion time 6 days later on May 7 at 12:00. The completion time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> which started on 06:00 on May 6 (last Line 5 inop condition results in completion time is 06:00 on May 9) is limited to less time because of the "modified time zero - 6 days from discovery of failure to meet the LCO" which IS DISCUSSED IN THE TS BASES. Per TS BASES B3.8.1, RA A.3 DISCUSSION: the third completion time for required action A.3 established a limit on the maximum time allowed for any combination of required AC sources to be inoperable during any single contiguous occurrence of failing to meet the LCO. The 6 day completion time provides a limit on the time allowed in a specified condition after discovery of failure to meet the LCO. The "AND" connector between the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and 6 day completion times apply simultaneously, and the more restrictive must be met. The completion time of required action A.3 allows for an exception to the normal "time zero" for beginning the allowed outage time clock. This exception results in establishing the "time zero" at the time the LCO was INITIALLY NOT MET, instead of at the time Condition A was re-entered. Therefore, Line 5 must be operable no later than 6 days from declaring the LCO statement not met (which was 12:00 on May 1) which means that Line 5 must be operable by 12:00 on May 7 to avoid entering Condition F which is a Condition/Required Action for a plant shutdown.

C: Incorrect -IF Condition F or Condition G was required to be entered, then "entry into a REQUIRED ACTION" that required a plant shutdown existed. Condition F would be required if Associated Completion Time of Condition A,B,C,D or E is not met. The correct restoration time for restoring Line 5 is also incorrect. See discussion on choice A.

D: Incorrect - IF Condition F or Condition G was required to be entered, then "entry into a REQUIRED ACTION" that required a plant shutdown existed. Worst case was 2 sources inoperable when Div 1 and Div 3 EDGs were inoperable together between 5/4 1600 and 5/5 1400. Since at no time were "Three or more required AC sources 54

Nine Mile Point Unit 22010 NRC SRO Written Examination inoperable", then Condition G was not required to be entered.

Question: SRO #100 The plant is at rated conditions.

Surveillance testing of RCIC is required and it is necessary to place "A" RHR into Suppression Pool Cooling.

Giving these conditions, which one of the following is required prior to placing "A" RHR into Suppression Pool Cooling and the bases for it?

A. Declare the Suppression Pool Cooling mode of "An RHR inoperable. This is because the suppression pool cooling valves will be inoperable in the open position if a loss of offsite power and the associated diesel failed to start were to occur while aligned for suppression pool cooling.

B. Declare the LPCI mode of "A" RHR inoperable. This is because "A" RHR may not inject into the vessel within the analyzed time frame if a LOCA occurs while aligned for suppression pool cooling.

C. Declare the LPCI mode of "A" RHR inoperable. This is because a loss of offsite power while aligned for suppression pool cooling will drain the RHR loop and create a potential for subsequent water hammer.

D. Declare all modes of "A" RHR inoperable. This is because a loss of offsite power while aligned for suppression pool cooling will drain the RHR loop and create a potential for subsequent water hammer.

Answer: B 56

Nine Mile Point Unit 2 2010 NRC SRO Written Examination Explanation (Optional):

A: Incorrect: LPCI mode is declared inoperable. Plausible in that the situation described would be true.

B: Correct: LPCI is declared inoperable per procedure N2-0P-31 due to a concern that with the pump running injection may not occur within the analyzed time frame if a LOCA were to occur.

C: Incorrect: Plausible in that this is a precaution in OP-31 but is not the reason for declaring the system inoperable.

D: Incorrect: Plausible in that a drain down of the loop would affect all modes of operation but this is not the reason for declaring the system inoperable.
