Level RO Tier# 2 Group# 1 KIA# 223002 K3.03 Importance Rating 3.6 PCIS/Nuclear Steam Supply Shutoff Knowledge of the effect that a loss or malfunction of the PRIMARY CONTAINMENT ISOLATION SYSTEM/NUCLEAR STEAM SUPPLY SHUT-OFF will have on following: Off-site radioactive release rates Proposed Question: #5 Unit 1 has experienced a loss of coolant accident with the following:

  • The Suppression Pool is being vented using the Standby Gas Treatment system (SGTS) due to the presence of hydrogen.
  • SGTS Exhaust Vent Monitor A (RE-012-0N017 A) fails downscale.
  • SGTS Exhaust Vent Monitor B (RE-D12-0N017B) indicates 25 mR/hr, up slow.

Which one of the following describes the resulting status of the release from this flow path? The release from this flow path ... A. continues at the initial rate. B. continues at half the initial rate. C. is stopped by closure of two isolation valves. D. is stopped by closure of just one isolation valve. Page 9 of164

Proposed Answer: D Explanation: RE-D12-0N017A and Beach close one isolation valve, HV-15703 and HV-25703 respectively, in this flow path if they exceed 23 mR/hr. With RE-D12-0N017A failed downscale, HV-15703 does not close. With RE-D12-0N017B indicating 25 mR/hr, HV-25703 closes. This valve closure stops the release from this flow path. Note: The question meets the KIA by presenting a high release rate to the environment (high SGTS exhaust radiation) and requiring the candidate to determine how a failure of PCIS affects the release rate (one SGTS exhaust radiation monitor failed downscale; SGTS high exhaust radiation isolation of the given valves is a PCIS function per TS 3.3.6.1 ). A. Incorrect - With RE-D12-0N017B indicating 25 mR/hr, HV-25703 closes. This valve closure stops the release from this flow path. Plausible if isolation logic needed both rad monitors high to cause valve closure, or if 25 mR/hr was not above the isolation setpoint. B. Incorrect-With RE-D12-0N017B indicating 25 mR/hr, HV-25703 closes. This valve closure stops the release from this flow path. Plausible because only 1 out of 2 isolation valves close with the given malfunction. C. Incorrect-With RE-D12-0N017A failed downscale, HV-15703 does not close. Plausible if logic was 1 out of 2 to close both isolation valves.

  • Reactor coolant temperature is 120°F, down slow.
  • RHR pump 1A is operating in the Shutdown Cooling (SDC) lineup.
  • A leak develops on the RHR pump 1A suction flange.
  • The leak does NOT cause a high SDC flow isolation.
  • Reactor water level is 54", down slow.

Which one of the following identifies the Reactor water level at which an isolation signal will first be generated that will stop this leak? A. 13"

8. -30" C. -38" D. -129" Page 11 of 164

Proposed Answer: A Explanation: At 13", an isolation signal will be received that will close the following valve to isolate this leak:

  • HV-151-FOOB, SHUTDOWN CLG SUCT OB ISO
  • HV-151-F009, SHUTDOWN CLG SUCT IB ISO
  • HV-151-F015A, RHR INJ OB ISO
  • HV-151-F015B, RHR INJ IB ISO Note: The question meets the KIA because it presents a malfunction of the SOC system (system leak that does not cause high flow isolation) and requires the candidate to determine the effect on Reactor water level (magnitude of Reactor water level drop before an automatic isolation signal is generated).

B. Incorrect-An isolation signal that will isolate this leak is first received at 13". -30" is the Reactor water level at which RCIC gets a start signal. C. Incorrect-An isolation signal that will isolate this leak is first received at 13". Another isolation signal is received at -38". D. Incorrect-An isolation signal that will isolate this leak is first received at 13". -129" is the Reactor water level at which RHR gets a LPCI initiation signal.

Level RO Tier# 2 Group# 1 KIA# 239002 K4.08 Importance Rating 3.6 SRVs Knowledge of RELIEF/SAFETY VALVES design feature(s) and/or interlocks which provide for the following: Opening of the SRV from either an electrical or mechanical signal Proposed Question: #7 Unit 1 is operating at 100% power with the following:

  • 125 voe 10614 is de-energized due to a sustained electrical fault.
  • A Main Turbine trip occurs and Turbine Bypass Valves are slow to operate.
  • Reactor pressure reaches a peak of 1220 psig during the resulting transient.

Which one of the following describes the operation of the SRVs during this transient? A. NO SRVs open on an electrical signal. At least one SRV opens by self-actuation (safety function). B. NO SRVs open on an electrical signal. NO SRVs open by self-actuation (safety function). C. All 16 SRVs open on an electrical signal. NO SRVs open by self-actuation (safety function). D. All 16 SRVs open on an electrical signal. At least one SRV opens by self-actuation (safety function). Page 13of164

Proposed Answer: A Explanation: Loss of 1D614 results in loss of the relief function of all 16 SRVs, meaning they will not open on high pressure due to an electrical signal. The SRVs can also open on high pressure due to self-actuation (mechanical opening based on Reactor pressure overcoming spring pressure). This is referred to as the safety function. The 16 SRVs have safety function set pressure requirements ranging from 1140 psig to 1241 psig. With Reactor pressure reaching a peak of 1220 psig due to slow operation of the Turbine Bypass Valves, multiple SRVs opened by self-actuation. B. Incorrect - Reactor pressure rose high enough to open multiple SRVs via the safey function. Plausible because normally operation of TBVs and/or opening of SRVs via the relief function would prevent this from happening. C. Incorrect - No SRVs opened on an electrical signal due to the loss of 1D614. Plausible because other electrical functions of the SRVs remain operable (ADS, opening using key lock switches in lower relay room). Reactor pressure rose high enough to open multiple SRVs via the safey function. Plausible because normally operation of TBVs and/or opening of SRVs via the relief function would prevent this from happening. D. Incorrect- No SRVs opened on an electrical signal due to the loss of 1D614.

Level RO Tier# 2 Group# 1 KIA# 259002 K4.14 Importance Rating 3.4 Reactor Water Level Control Knowledge of REACTOR WATER LEVEL CONTROL SYSTEM design feature(s) and/or interlocks which provide for the following: Selection of various instruments to provide reactor water level input Proposed Question: #8 Unit 2 is operating at 100% power with the following Reactor water level inputs to ICS:

  • NRLA +28inches
  • NRLBB +SO inches
  • NRLC +35inches
  • UPSETLB +33inches Which one of the following describes the ICS response to these inputs?

A. The NRLBB input to the average level calculation is replaced by NRLC. B. The NRLBB input to the average level calculation is replaced by UPSETLB. C. Level control will switch from using the average level calculation to using NRLC. D. Level control will switch from using the average level calculation to using UPSETLB. Page 15of164

Proposed Answer: 8 Explanation: ICS has a level validation scheme. A low median signal is selected from NRLA, NRLBB, NRLC and UPSETLB. ICS disregards both the high signal and the low signal. Of the two median (middle) signals ICS chooses the low median for level instrument validation. In this case, the low median signal is 33", based on UPSETLB. If an input deviates by more than 10" from the low median signal, it is marked as DEVIANT. In this case, NRLBB is more than 1O" above the low median signal, and therefore DEVIANT. This causes NRLBB to be replaced in the average level calculation by the low median signal of 33" from UPSETLB. A. Incorrect - NRLBB is replaced by the low median signal, which is 33" from UPSETLB. Plausible because NRLC is the high median signal, indicates at the normal Reactor water level, and is higher priority than UPSETLB in the separate auto selected level logic. C. Incorrect- Since only one signal (NRLBB) is DEVIANT, ICS will continue to use average level calculation, just with the NRLBB signal replaced. Average level calculation is abandoned if a second NRL instrument is lost and NRLC is one of the possible replacements. NRLA is low enough below low median to cause an alarm, but not so low to be marked DEVIANT. D. Incorrect - Since only one signal (NRLBB) is DEVIANT, ICS will continue to use average level calculation, just with the NRLBB signal replaced. Average level calculation is abandoned if a second NRL instrument is lost and UPSETLB is one of the possible replacements. NRLA is low enough below low median to cause an alarm, but not so low to be marked DEVIANT.

  • Total Core Spray flow is 6700 gpm.

Which one of the following describes the status of core cooling via Spray Cooling, in accordance with the Emergency Operating Procedures? Adequate core cooling via Spray Cooling is currently ... A. being provided. B. NOT being provided because Core Spray flow is too low. C. NOT being provided because Reactor water level is too low. D. NOT being provided because only one loop of Core Spray is injecting. Page 17 of164

Proposed Answer: A Explanation: Adequate core cooling via Spray Cooling is currently being provided because Reactor water level is above -21 O" and one loop of Core Spray is injecting greater than 6350 gpm to the Reactor. B. Incorrect - One Core Spray loop is injecting greater than 6350 gpm to the Reactor, therefore that aspect of Spray Cooling is satisfied. Plausible if candidate believes a higher Core Spray flow is required. C. Incorrect - Reactor water level is above -21 O", therefore that aspect of Spray Cooling is satisfied. Plausible because Reactor water level is below the levels for adequate core cooling by other means (-161" for submergence, -179" is steam cooling in E0-100-102). D. Incorrect - One Core Spray loop is injecting greater than 6350 gpm to the Reactor, therefore that aspect of Spray Cooling is satisfied.

ELECTRICAL DISTRIBUTION: Breaker control Proposed Question: #1 O A Unit 1 startup is in progress with the following:

  • The Main Generator has been synchronized to the grid.
  • Aux Bus 11A is being transferred to the Main Generator supply.
  • The control switch for AUX XFMR 11 TO BUS 11A BKR 1A10101 sticks in the CLOSE position when released, and cannot be returned to the Normal After Close position.
  • AUX XFMR 11 TO BUS 11A BKR 1A10101 closes.

Which of the following describes the Unit 1 response? A. TIE BUS TO BUS 11A BKR 1A10104 immediately opens. Aux Bus 11A ends up fed from the Aux Transformer only. B. TIE BUS TO BUS 11A BKR 1A10104 opens after a 10-second time delay. Aux Bus 11A ends up fed from the Aux Transformer only. C. AUX XFMR 11 TO BUS 11A BKR 1A10101 opens after a 10-second time delay. Aux Bus 11A ends up fed from Startup Bus 10 only. D. TIE BUS TO BUS 11A BKR 1A10104 and AUX XFMR 11 TO BUS 11A BKR 1A10101 remain closed. Aux Bus 11A ends up fed from both Startup Bus 10 and the Aux Transformer. Page 19of164

Proposed Answer: D Explanation: On normal transfer of this bus, Tl E BUS TO BUS 11 A BKR 1A10104 opens once the control switch for AUX XFMR 11 TO BUS 11A BKR 1A10101 returns to Normal After Close (red flagged and neutral). This breaker opening logic requires the related control switch in NAT/NAC, the related sync switch ON, and the related Aux Incoming breaker closed. Without all three conditions, TIE BUS TO BUS 11A BKR 1A10104 remains closed. There is no automatic re-opening logic that will cause AUX XFMR 11 TO BUS 11A BKR 1A10101 to open. Therefore, both breakers remain closed and Aux Bus 11A ends up fed from both Startup Bus 10 and the Aux Transformer. A. Incorrect- 1A10104 will NOT immediately open. Plausible because it would immediately open if not for the control switch malfunction. B. lncorrect-1A10104 will NOT open after a time delay. Plausible because it would normally open if not for the control switch malfunction and there is a 10 second time delay associated with electrical bus undervoltage logic. C. Incorrect- 1A10101 will NOT open after a time delay. Plausible because normal interlock prevents the Aux Bus from being supplied by both sources for a prolonged period of time, the control switch has malfunctioned, and there is a 10 second time delay associated with electrical bus undervoltage logic.

  • Instrument Air Compressor (IAC) 1K107A is running in LEAD.
  • The sensed aftercooler outlet air temperature drifts upscale over approximately one (1) minute.

Which one of the following describes the response of Turbine Building Closed Cooling Water (TBCCW) flow to the aftercooler and the response of IAC 1K 107A? TBCCW flow to the aftercooler ... A. rises. IAC 1K107A trips. B. rises. IAC 1K107A does NOT trip. C. remains the same. IAC 1K107A trips. D. remains the same. IAC 1K107A does NOT trip. Page 21 of 164

Proposed Answer: A Explanation: TBCCW flow to the aftercooler is automatically modulated by temperature control valve TCV12504A 1 based on sensed aftercooler outlet air temperature. With temperature drifting high, TCV12504A 1 opens to raise TBCCW flow in an attempt to lower temperature. Actual aftercooler outlet air temperature will therefore lower, but sensed temperature continues to drift upscale based on the given failure. IAC 1K107A trips when sensed temperature exceeds 320°F.

8. Incorrect- IAC 1K107A trips based on aftercooler outlet air temperature >320°F. Plausible because not all sensed IAC parameters lead to a trip.

C. Incorrect - TBCCW flow rises due to the automatic response of TCV12504A 1. Plausible because only certain TBCCW loads have automatic TCVs such as this. D. Incorrect - TBCCW flow rises due to the automatic response of TCV12504A 1. Plausible because only certain TBCCW loads have automatic TCVs such as this.

  • Non-Class 1E Instrument AC UPS 10130 is in service.
  • Then, the UPS 10130 inverter fails and the inverter output goes to zero.

Which one of the following describes the effect on Instrument AC Distribution Panel 1Y128? 1Y128 is ... A. automatically powered by UPS 10130 from 18246.

8. automatically powered by UPS 10130 from 10133.

C. automatically powered by the Static Switch from 18226. D. de-energized and must be manually transferred to 18226. Page 23of164

Proposed Answer: c Explanation: Panel 1Y128 is normally powered by UPS 10130 from 18246 through the inverter. When the inverter fails and its output goes to zero, power from 18246 is interrupted. The backup power supply from 10133 also requires the inverter to be functioning, so it does not automatically supply power in this case. UPS 10130 has a static switch that does not require the inverter to be functioning to supply 1Y128. Therefore, this static switch automatically supplies 1Y128 with power from 18226 with the given malfunction. A. Incorrect- The static switch automatically supplies 1Y128 with power from 18226. Plausible because 18246 is the normal power source to 1Y128. B. Incorrect- The static switch automatically supplies 1Y128 with power from 18226. Plausible because 10133 is the normal backup power supply, but also requires a functioning inverter to supply 1Y128.

  • Drywell inerting is in progress.
  • Nitrogen is being added to the Drywell.
  • Standby Gas Treatment (SGTS) fan A is running and aligned to take suction from the Unit 1 Drywell only.
  • Drywell pressure is 0.07 psig, down slow.

Then, the control switch for DRWL/WETWELL BURP DMP HD-175088 is taken to CLOSE. Which one of the following describes the effect of this switch manipulation on Drywell pressure? Drywell pressure will. .. A. rise.

8. remain approximately constant.

C. continue to lower, but at a faster rate. D. continue to lower, but at a slower rate. Page 25 of 164

Proposed Answer: A Explanation: The Drywell is initially being inerted by adding nitrogen and simultaneously venting air through SGTS fan A through open series dampers HD-17508A and HD-175088. The nitrogen addition rate is initially lower than the SGTS flow rate, therefore Drywell pressure is lowering slowly. When the control switch for DRWL/WETWELL BURP DMP HD-175088 is taken to CLOSE, HD-175088 closes. This completely isolates the SGTS flow path from the Drywell. No interlock exists which isolates the nitrogen flowing into the Drywell, so Drywell pressure will begin to rise. B. Incorrect - Drywell pressure rises because SGTS flow out is stopped while nitrogen flow in remains steady. Plausible if interlock also isolated the nitrogen flow path on low SGTS flow. There are other interlocks based on low SGTS flow. C. Incorrect - Drywell pressure rises because SGTS flow out is stopped while nitrogen flow in remains steady. Plausible if this damper isolated the nitrogen flow path instead of the SGTS flow path. D. Incorrect - Drywell pressure rises because SGTS flow out is stopped while nitrogen flow in remains steady. Plausible if this damper was only associated with the SGTS train B or had an interlock to not close before the fan was stopped.

Proposed Answer: D Explanation: An IRM INOP condition results from detector power supply high voltage low. A control rod withdrawal block is generated by the INOP condition. An RPS half scram signal is also generated by the INOP condition. To clear these conditions, IRM B must be bypassed, and RPS must be reset by rotating RPS SCRAM RESET HS to both GRP 1/4 and GRP 2/3 positions. A. Incorrect-A rod block and half scram occur. Plausible because the IRM downscale by itself will not generate a control rod block or half scram, as IRMs are on Range 1 with all control rods inserted and startup about to commence. B. Incorrect - A half scram occurs. Plausible because, in other conditions, an IRM downscale by itself only causes a rod block. C. Incorrect- In this situation GRP 2/3 must also be reset.

Page 40of164 Proposed Answer: B Explanation: When Reactor water level drops below 13" (at approximately 2 seconds), an automatic Reactor scram signal is generated. The scram results in Scram Air Header pressure dropping to 0 psig. For the scram to be reset, at least 1O seconds must pass after the initial scram. This time delay is designed to ensure all control rods insert. Additionally, the initiating condition must be clear for the scram to be reset. The scram reset time delay times out at approximately 12 seconds. Reactor water level recovers above 13" at approximately 20 seconds. Therefore, the earliest time in this scenario that the Scram Air Header can be re-pressurized is approximately 20 seconds. A. Incorrect- The Scram Air Header cannot be re-pressurized until approximately 20 seconds. 12 seconds is plausible because this is when the 10 second time delay from the initiating scram expires, however Reactor water level is still too low to reset the scram. C. Incorrect- The Scram Air Header can be re-pressurized at the earlier time of approximately 20 seconds. 30 seconds is plausible because this is 25 seconds after Reactor water level reached -30". 25 seconds is the time delay for resetting ARI, which actuates at -38", not - 30". -30" is the level at which RCIC initiates. D. Incorrect - The Scram Air Header can be re-pressurized at the earlier time of approximately 20 seconds. 55 seconds is plausible because this is 25 seconds after Reactor water level recovered above 13". 25 seconds is the time delay for resetting ARI, but not an RPS scram signal.

Plausible if the controller was setup to be reverse acting, as they are at many plants, or if it controlled a bypass valve, which upon opening decreased flow through the heat exchanger. B. Incorrect - RBCCW temperature lowers due to more Service Water flow through the RBCCW heat exchangers. Plausible if the controller was setup to be reverse acting, as they are at many plants, or if it controlled a bypass valve, which upon opening decreased flow through the heat exchanger. C.

  • Diesel Generator (DG) C is out of service due to catastrophic turbocharger failure.
  • DG E has not yet been transferred for DG C.
  • At time T=O seconds, a loss of all offsite power occurs.
  • At time T=30 seconds, a DBA LOCA occurs.

Which one of the following describes how many Core Spray pumps will start and when? A. Only three Core Spray pumps will start at T=40.5 seconds B. All Core Spray pumps will start at T=40.5 seconds C. Only three Core Spray pumps will start at T=45 seconds D. All Core Spray pumps will start at T=45 seconds Page 52 of 164

Proposed Answer: A Explanation: At time T=O seconds, the loss of all offsite power causes DGs A, B, and D to automatically start and close in on ESS buses 1A, 1B, and 10, respectively. ESS bus 1C will de-energize, preventing the start of Core Spray pump 1C later when the OBA LOCA occurs. Due to the loss of offsite power, Core Spray pumps 1A, 1B, and 1D start with a time delay of 10.5 seconds. Therefore, Core Spray pumps 1A, 1B, and 1D start at time T=40.5 seconds. B. Incorrect - Core Spray pump 1C does not start. Plausible because some other plants have two DGs load onto each ESS bus, such that loss of just one DG would not prevent any Core Spray pump from starting. C. Incorrect- Core Spray pumps start at 40.5 seconds, not 45 seconds. Plausible because Core Spray pumps normally have a time delay of 15 seconds when starting on a LOCA signal, which would make them start at 45 seconds. D. Incorrect - Core Spray pump 1C does not start. Plausible because some other plants have two DGs load onto each ESS bus, such that loss of just one DG would not prevent any Core Spray pump from starting. Core Spray pumps start at 40.5 seconds, not 45 seconds.

0. (1) 10666 (2) Its dedicated battery for approximately 20 minutes, then by MCC 18216.

Page 54of164

Proposed Answer: B Explanation: MCC 18236 is the preferred source for UPS 10240. When MCC 18236 is lost, the UPS initially is powered from its dedicated battery. This lasts approximately 20 minutes. Then the UPS swaps to the alternate AC source, MCC 18216. A. Incorrect - The UPS first swaps to the battery source, then to the alternate AC source after the battery discharges for approximately 20 minutes. Plausible because swapping to the alternate AC source first would preserve battery capacity. C. Incorrect- UPS 10666 is normally supplied by MCC 18246, not 18236. Plausible because these are similar MCCs. The UPS first swaps to the battery source, then to the alternate AC source after the battery discharges for approximately 20 minutes. Plausible because swapping to the alternate AC source first would preserve battery capacity.

  • Condensate pumps 1A, 1B, and 1Dare operating.
  • Condensate pump 1C is secured.

Then, a steam leak in the Drywell results in the following:

  • The Reactor automatically scrams due to high Drywell pressure.
  • Reactor water level reaches a low of -20", then recovers to the normal band.
  • Drywell pressure is 4 psig, up slow.

Which one of the following describes the number of operating Condensate pumps one (1) minute later? A. Zero (0) B. Two (2) C. Three (3) D. Four (4) Page 56of164

Proposed Answer: A Explanation: The Reactor scram leads to the Main Generator lockouts tripping. With a LOCA signal present due to Drywell pressure above 1.72 psig, the Main Generator lockout leads to Aux Bus load shedding and slow transfer of the Aux buses. This load shedding scheme trips all Condensate pumps to prevent overloading ESS transformers. Therefore, zero Condensate pumps remain operating. B. Incorrect- Zero Condensate pumps remain operating due to the combination of Main Generator lockout and LOCA signal resulting in Aux Bus load shedding. Plausible because ON-SCRAM-101 PCO Actions allow reducing the number of operating Condensate pumps to two. C. Incorrect - Zero Condensate pumps remain operating due to the combination of Main Generator lockout and LOCA signal resulting in Aux Bus load shedding. Plausible because three Condensate pumps were initially running. D. Incorrect - Zero Condensate pumps remain operating due to the combination of Main Generator lockout and LOCA signal resulting in Aux Bus load shedding. Plausible because Reactor water level lowered below +13", which initiates automatic Feedwater response in the form of Setpoint Setdown, just not auto-start of the standby Condensate pump.

  • RHR loop 1A is operating in Suppression Pool cooling.
  • HV-151-F048A, HX A SHELL SIDE BYPS, is fully closed.

Then, a steam leak in the Drywell results in the following:

C. closed and may be re-positioned without override. D. closed and requires an override to be re-positioned. Page 58of164

Proposed Answer: B Explanation: HV-151-F048A automatically opens when Drywell pressure exceeds 1.72 psig to allow a higher flow rate from LPCI (both through and around the heat exchanger. This open signal also seals in. Therefore, in order to close HV-151-F048A (to force more water through the heat exchanger and provide greater cooling of the spray flow), the open signal must be overridden. A. Incorrect - The open signal seals in, therefore it must be overridden to re-position the valve. Plausible because the open signal could not seal in since this valve is likely be re-positioned in a situation with high Drywell pressure. C. Incorrect-Although HV-151-F048A was initially closed, it automatically opens when Drywell pressure exceeds 1.72 psig. Plausible for this valve to remain closed to ensure cooling of LPCI flow by directing it all through the heat exchanger.

B. enforces a rod withdrawal block, but NOT a rod insert block. C. does NOT enforce a rod block, but does provide protection for both selected control rods. D. does NOT enforce a rod block, but only provides protection for one of the selected control rods. Page 60 of164

Proposed Answer: B Explanation: When the RBM detects more than one control rod selected at the same time, an INOP trip is generated. The INOP trip results in a rod withdrawal block, but not a rod insert block. A. Incorrect-The INOP trip results in a rod withdrawal block, but not a rod insert block. Plausible because other system malfunctions (RWM INOP, RDCS failure) result in rod insert blocks also. C. Incorrect - The RBM has a feature that detects more than one control rod selected at the same time and enforces a rod withdrawal block. Plausible because if this feature did not exist, the RBM circuitry would have to be designed to either protect both selected rods or just one (first selected vs. last selected). D.

  • HPCI testing has just been completed.
  • RHR loop A is operating in the Suppression Pool Cooling lineup.

Then, a loss of coolant accident results in the following:

Page 63of164 Page 64of164 Proposed Answer: B Explanation: With Suppression Pool Cooling initially in service, F017A and F015A are closed, F028A and F024A are open, and F07A is normally closed (RHR min flow valve is normally open) but could be open if flow was low enough through the cooling flow path. When Drywell pressure exceeds 1. 72 psig and/or Reactor water level lowers below -129", the Suppression Pool Cooling lineup secures (F028A and F024A close). However, since Reactor pressure is above approximately 420 psig (407-433 psig range per TS 3.3.5.1), the LPCI injection valves (F017A and F015A) do not yet receive a signal to open and therefore remain closed. This combination of valve closures results in low flow, therefore the minimum flow valve (F07 A) should be open. A. Incorrect- F07A should be open due to the low flow condition. Plausible because a LOCA signal is present and LPCI injection valves will soon open. C. Incorrect - F017A and F015A should be closed because Reactor pressure is above 420 psig. Plausible because a LOCA signal is present which has already causes F028A and F024A to re-position. D. Incorrect- F028A and F024A should be closed because Drywell pressure is above 1.72 psig and Reactor water level is below -129". Plausible because these two valves were initially open for the SPC lineup, and Reactor pressure is still above the value at which LPCI injection actually occurs.

  • The Reactor Mode Switch is in REFUEL.
  • One control rod is withdrawn to position 04.
  • A fuel bundle is latched on the Refuel Platform grapple in the Spent Fuel Pool.
  • The Refuel Platform grapple is in the Normal Up position.

Which one of the following describes when fuel movement would first be interrupted by an interlock if the Refuel Platform Operator attempted to place the fuel bundle in the Unit 1 core? This fuel movement would first be interrupted by an interlock ... A. as soon as any attempt is made to move the Refuel Platform towards the core. B. when the Refuel Platform reaches a position close to the core. C. as soon as any attempt is made to lower the fuel bundle once over the core. D. when the bottom of the fuel bundle is lowered enough to reach the height of the core top guide. Page 66of164

Proposed Answer: B Explanation: This movement would first be interrupted by the Bridge Reverse #1 interlock. This interlock stops Refuel Platform motion when the Refuel Platform is nearing a location over the core, a control rod is withdrawn, and the grapple is loaded. A. Incorrect- Motion towards the core is allowed until the Refuel Platform nears a position over the core. Plausible because motion towards the core will eventually be interrupted, just not until the Refuel Platform nears the core, and this also would prevent loading fuel with a rod out. C. Incorrect - The fuel movement would be interrupted earlier than this before the Refuel platform moved over the core. Plausible because if the Bridge Reverse #1 interlock failed, a separate interlock would prevent lowering the grapple. D. Incorrect- The fuel movement would be interrupted earlier than this before the Refuel platform moved over the core. Plausible because if the Bridge Reverse #1 interlock failed, a separate interlock would prevent lowering the grapple.

  • Radwaste tanks are in a normal alignment.
  • An unidentified leak has developed in the Drywell.
  • Input to the Drywell Floor Drain sumps has risen from 0.3 gpm to 1.9 gpm in the last four hours.
  • No change has been made to Radwaste tank alignment based on this leak.

Which one of the following describes: (1) the Radwaste tanks that will be receiving this excess leakage, and (2) whether the leakage exceeds any Technical Specification limit? (1) Radwaste Tanks That (2) Leakage Exceeds Any Receive This Excess Leakage Technical Specification Limit? A. Surge Tanks No B. Surge Tanks Yes C. Collection Tanks No D. Collection Tanks Yes Page 73 of 164

Proposed Answer: c Explanation: The Drywell Floor Drain sumps discharge to the Reactor Building sumps, which then are normally aligned to discharge to the Radwaste Collection Tanks. This leakage represents a rise in Unidentified Leakage of 1.6 gpm in four hours. This is within the TS 3.4.4 limit of s 2 gpm increase in Unidentified Leakage in a four hour period while in Mode 1. The TS 3.4.4 limit of s 5 gpm Unidentified Leakage is also not exceeded. Note: The KIA requires testing the impact of a "system rupture" on Radwaste, including use of procedure(s) to correct, control, or mitigate the impact. The term "system rupture" is interpreted as either a rupture of some component within the Radwaste system or a rupture of an external system that directly impacts Radwaste. Additionally, NUREG 1123 indicates the Radwaste system includes plant sumps and drains. Therefore, the question meets the KIA by:

  • giving a system rupture (RCS system inside Drywell) that impacts Radwaste (Drywell floor drain sumps),
  • requiring prediction of the associated impact (Radwaste tank that receives leakage), and
  • requiring determination of correct procedure usage to deal with the impact (assessing status of Technical Specification leakage limits).

While the question stem does not specifically mention a "system rupture", the question meets the KIA by presenting leakage consistent with a rupture of a small system line in the Drywell (such as an instrument line). A. Incorrect - The Drywell Floor Drain sumps discharge to the Reactor Building sumps, which then are normally aligned to discharge to the Radwaste Collection Tanks. Plausible because an alternate alignment is available to the Surge Tanks. B. Incorrect - The Drywell Floor Drain sumps discharge to the Reactor Building sumps, which then are normally aligned to discharge to the Radwaste Collection Tanks. Plausible because an alternate alignment is available to the Surge Tanks. This leakage represents a rise in Unidentified Leakage of 1.6 gpm in four hours. This is within the TS 3.4.4 limit of s 2 gpm increase in Unidentified Leakage in a four hour period while in Mode 1. The TS 3.4.4 limit of s 5 gpm Unidentified Leakage is also not exceeded. Plausible because this is a significant rise in leakage over a short period of time, elevated well above normal rates, and is in excess of 1 gpm. D. Incorrect - This leakage represents a rise in Unidentified Leakage of 1.6 gpm in four hours. This is within the TS 3.4.4 limit of s 2 gpm increase in Unidentified Leakage in a four hour period while in Mode 1. The TS 3.4.4 limit of s 5 gpm Unidentified Leakage is also not exceeded. Plausible because this is a significant rise in leakage over a short period of time, elevated well above normal rates, and is in excess of 1 gpm.

Unit 1 is operating at 100% power with the following:

  • Unit 1 experiences a loss of Feedwater.
  • The Unit 1 Reactor is manually scrammed.
  • Unit 1 Reactor water level drops to a low of -45".
  • Unit 1 Reactor water level is recovered to +35", stable, using HPCI and RCIC.

Which of the following describes the response of the Reactor Building Ventilation zones (I, II, Ill)? Zone I Zone II Zone Ill A Isolates Isolates Isolates

8. Does NOT isolate Isolates Isolates C. Isolates Does NOT isolate Isolates D. Does NOT isolate Does NOT isolate Does NOT isolate Page 76of164

Proposed Answer: c Explanation: Unit 1 Reactor water level below -38" causes both a Zone I and Zone Ill isolation signal. Zone II does not receive an isolation signal because Unit 2 Reactor water level and Drywell pressure are unaffected. A. Incorrect - Zone II does not receive an isolation signal because Unit 2 Reactor water level and Drywell pressure are unaffected. Plausible if candidate confuses Zones and because the low Reactor water level does partially affect Unit 2 through the Zone Ill isolation. B. Incorrect- Zone I does receive an isolation signal and Zone II does not receive an isolation signal because Unit 2 Reactor water level and Drywell pressure are unaffected. Plausible because this is the correct answer if the transient happened on Unit 2 instead of Unit 1. D. Incorrect- Unit 1 Reactor water level below -38" causes both a Zone I and Zone Ill isolation signal. Plausible because this would be the correct answer if Reactor water level lowered slightly less.

Calculated CTP NRHX Outlet Temperature A. Lowers Lowers B. Lowers Rises C. Rises Lowers D. Rises Rises Page 78of164

Proposed Answer: D Explanation: Calculated CTP rises due to the change in RWCU flow upon establishing letdown flow. NRHX outlet temperature rises due to greater RWCU flow with no additional RBCCW flow. A. Incorrect - Calculated CTP rises due to the change in RWCU flow upon establishing letdown flow. NRHX outlet temperature rises due to greater RWCU flow with no additional RBCCW flow. Both plausible if candidate does not understand the interaction between RWCU letdown flow and these parameters. B. Incorrect- Calculated CTP rises due to the change in RWCU flow upon establishing letdown flow.

Proposed Question: #37 Unit 1 is operating at 100% power when annunciator AR-103-HOS, CRD PANEL 1C007 HI TEMP, alarms due to high temperature on one control rod. Which one of the following describes the ability of this annunciator to re-flash if a second control rod experiences a high temperature and the location of CRD panel 1COO?? Will Annunciator Re-Flash? Panel Location A. No Relay Room B. No Reactor Building C. Yes Relay Room D. Yes Reactor Building Page 80of164

Proposed Answer: B Explanation: Annunciator AR-103-H05 is provided with re-flash capability, such that if a second CROM alarms on high temperature the alarm will not be masked. This is only available after the local pael has been reset. If no operator action is taken, the annunciator will not re-flash. CRO panel 1COO? is located in the Reactor Building. A. Incorrect - Annunciator AR-103-H05 is provided with re-flash capability, such that if a second CROM alarms on high temperature the alarm will not be masked. Plausible because some multi-point alarms do not have such a re-flash capability. CRO panel 1COO? is located in the Reactor Building. Plausible because the Relay Room contains many panels/indications. C. Incorrect - CRO panel 1COO? is located in the Reactor Building. Plausible because the Relay Room contains many panels/indications.

0. Incorrect -Annunciator AR-103-H05 is provided with re-flash capability, such that if a second CROM alarms on high temperature the alarm will not be masked. Plausible this alarm does have a re-flash capability but is not active until the local panel is reset..

  • Reactor power is approximately 1%.
  • The Mechanical Vacuum pump (MVP) is operating.
  • The Main Steam Isolation Valves (MSIVs) are open.

Then, major fuel damage occurs as a result of defective fuel bundles:

  • AR-111-C03, MN STM LINE RAD MONITOR HI RADIATION, alarms.
  • AR-103-D01, MN STM LINE HI HI RADIATION, alarms.
  • AR-104-D01, MN STM LINE HI HI RADIATION, alarms.

Which one of the following describes the response of the MVP and the MS IVs? The MVP ... A. remains in service unless manually secured and the MSIVs remain open unless manually closed. B. remains in service unless manually secured and the MSIVs automatically isolate. C. automatically trips and the MSIVs remain open unless manually closed. D. automatically trips and the MSIVs automatically close. Page 82 of 164

Proposed Answer: c Explanation: Major fuel damage will cause the Main Steam Line radiation monitors to reach the hi-hi trip setpoint. This causes the Mechanical Vacuum pump to trip. The MSIV isolation on hi-hi Main Steam Line radiation has been removed, therefore the MSIVs remain open unless manually closed. A. Incorrect- The MVP trips on hi-hi Main Steam Line radiation. Plausible since the MSIVs do not automatically isolate. B. Incorrect - The MVP trips on hi-hi Main Steam Line radiation. Plausible since the MSIVs do not automatically isolate. The MSIVs remain open unless manually closed. Plausible because original plant design include automatic MSIV isolation on hi-hi Main Steam Line radiation and manual isolation is still procedurally required. D. Incorrect -The MSIVs remain open unless manually closed. Plausible because original plant design include automatic MSIV isolation on hi-hi Main Steam Line radiation and manual isolation is still procedurally required.

Proposed Answer: B Explanation: A loss of 125 VDC to ESS Bus 1A results in a loss of breaker control functions. In a normal situation, a loss of the normal offsite power source would result in a fast transfer to the alternate supply and the DG would not start. However, with the loss of DC, the feeder breakers will not operate. The DG would not start, even with a loss of bus voltage, because it needs to see all three bus feeder breakers (Normal, Alternate, DC Output) open before a DG start signal occurs. A. Incorrect - ESS Bus 1A Normal Feeder Breaker would NOT trip open due to a loss of control power. Plausible that this breaker would have automatic DC backup power or maintain trip capability. C. Incorrect - ESS Bus 1A Normal Feeder Breaker would NOT trip open due to a loss of DC control power. Plausible that this breaker would have automatic DC backup power or maintain trip capability. The DG would not start - it needs to see all three bus feeder breakers (Normal, Alternate, DC Output) open.

However, Turbine Bypass Valves are unavailable in this situation due to automatic closure of the MS IVs due to the power loss. C. Incorrect- The Reactor does scram on this loss of power. Turbine Bypass Valves normally control Reactor pressure following a scram. 1040 psig is normal Reactor pressure at 100% power. However, Turbine Bypass Valves are unavailable in this situation due to automatic closure of the MS IVs due to the power loss. D. Incorrect- This loss of power results in an automatic Reactor scram. If no Reactor scram occurred, Reactor pressure would continue to be controlled -1040 psig by the Turbine Control Valves.

Proposed Answer: A Explanation: HV-151-F016A automatically closes given any of the following signals:

  • Reactor water level< -129"
  • Drywell pressure > 1. 72 psig
  • Manual Initiation Div 1 or 2 PB Armed and Depressed.

Therefore, HV-151-F016A closes automatically based on a Drywell pressure signal only for these conditions. B. Incorrect - The given value of Reactor water level is too high to cause a signal that causes this valve to close. Plausible because Reactor water level <-129" does cause the valve to close. C. Incorrect - The valve closes on a Drywell pressure signal. Plausible because Reactor water level is above -129", which is a separate closure signal. D.

Just one of the two steam supply isolation valves has automatically closed. D. is inoperable and unavailable. Both steam supply isolation valves have automatically closed. Page 137of164

Proposed Answer: c Explanation: Multiple temperature detectors input to annunciators AR-114-E05 and AR-114-F04. AR-114-F04 being in alarm based on high temperature in the HPCI equipment area causes the inboard steam supply isolation valve (HV-155-F002) to close. Since annunciator AR-114-F05 is NOT also in alarm, the outboard steam supply isolation valve (HV-155-F003) does NOT close. A. Incorrect - The HPCI isolation logic is setup such that high temperature logic A is sufficient alone to close one HPCI steam supply isolation valve. Plausible because many logics are setup such that they require both A and B to actuate to cause an automatic action. B. Incorrect - High temperature in the HPCI equipment area isolates the steam supply without time delay. Plausible because high temperature in the HPCI pipe routing area only causes an isolation after a 15 minute time delay.

The control rod must be notch withdrawn from position 12 to 32. The control rod may be withdrawn continuously from position 32 to 48. Page 147of164

Proposed Answer: A Explanation: All of the SRMs have increased well above their initial count rate, but none have reached 1Ox their initial count rate. G0-100-002 does not restrict continuous control rod withdrawal until one SRM reaches 1Ox its initial count rate. Therefore, the control rod may be continuously withdrawn from position 12 to 48. B. Incorrect - None of the SRMs have reached 1Ox their initial count rate, therefore continuous control rod withdrawal is not yet restricted. Plausible because all SRMs have reached at least 6x their initial count rate and SRM D has achieved 3 count rate doublings, which is a common threshold used in the industry. C. Incorrect - None of the SRMs have reached 1Ox their initial count rate, therefore continuous control rod withdrawal is not yet restricted. Plausible because all SRMs have reached at least 6x their initial count rate and SRM D has achieved 3 count rate doublings, which is a common threshold used in the industry. Position 16 is a plausible threshold because it is a common threshold for when control rod worth begins to become less significant. D.

  • A Main Turbine pressure regulator malfunction occurs.
  • Reactor pressure slowly rises to 1065 psig and stabilizes.

Which one of the following describes the impact of this Reactor pressure on Technical Specifications, if any? A. NO Technical Specification action is required. B. Technical Specifications require lowering Reactor pressure within a maximum of 15 minutes, but do NOT require an immediate Reactor scram. C. Technical Specifications require lowering Reactor pressure within a maximum of 1 hour, but do NOT require an immediate Reactor scram. D. Technical Specifications require an immediate Reactor scram. Page 150of164

Proposed Answer: B Explanation: Reactor pressure above 1050 psig requires entry into Technical Specification 3.4.11 Condition A. This condition requires restoring pressure within a maximum of 15 minutes. A. Incorrect- TS action is required because Reactor pressure is above the 1050 psig limit in TS 3.4.11. Plausible because Reactor pressure is still below other limits (1087 psig scram setpoint in TS 3.3.1.1, 1325 psig safety limit of TS 2.1.2). C. Incorrect - The maximum time allowed by TS 3.4.11 Condition A to restore pressure is 15 minutes, not one hour. Plausible because other TS use one hour completion times and ROs are responsible for knowing completion times up to one hour. D. Incorrect - An immediate Reactor scram is not required.

Proposed Answer: c Explanation: With Suppression Pool water level below 20.5', the Average SPOTMOS indication is no longer valid and the Bottom SPOTMOS indication must be used to determine Suppression Pool water temperature for use in E0-100-103. With Suppression Pool water level at 19' and Bottom SPOTMOS indication at 190°F, the 501-700 psig HCTL curve is satisfied, but the 701-900 psig HCTL curve is violated. Therefore, current Reactor pressure of 650 psig is acceptable, but Reactor pressure must be maintained at or below 700 psig. Current plant conditions are approximately 2-3°F below the 501-700 psig HCTL curve, therefore Emergency RPV Depressurization is not required. A. Incorrect - Current plant conditions are approximately 2-3°F below the applicable (501-700 psig) HCTL curve, therefore Emergency RPV Depressurization is not required. B. Incorrect- Current Suppression Pool conditions are within the 501-700 psig HCTL curve, but would violate the 701-900 psig HCTL curve. Therefore, the upper -100 psig of the current Reactor pressure band cannot be used. D. Incorrect- Reactor pressure must be maintained below 700 psig, not above, to satisfy HCTL.

  • A Feedwater Level Control malfunction occurs.
  • An Operator places the Reactor Mode Switch in SHUTDOWN.
  • 30 control rods remain withdrawn at position 48.
  • All other control rods fully insert.
  • Reactor water level reaches a low of -1 O" and then begins rising.
  • APRMs indicate 3%, steady.
  • E0-100-102, RPV Control, is entered.

Which one of the following describes the required procedure execution, in accordance with the Emergency Operating Procedures and OP-AD-300, Administration of Operations? A. Remain in E0-100-102 and restore Reactor water level to a band of 13" to 54". E0-100-113, Level/Power Control, entry is NOT required. B. Exit E0-100-102 and enter E0-100-113, Level/Power Control, based on control rod position. Remain in E0-100-113 and Reactor water level must be lowered to at least

       -60".

C. Exit E0-100-102 and enter E0-100-113, Level/Power Control, based on control rod position. Remain in E0-100-113 and Reactor water level may be stabilized at the current value. D. Exit E0-100-102 and enter E0-100-113, Level/Power Control, based on control rod position. Then return to E0-100-102 based on Reactor power and restore Reactor water level to a band of 13" to 54". Page 4 of57

Proposed Answer: c Explanation: Upon entry into E0-100-102, a diagnostic step is executed to determine the need for entry into E0-100-113, Level/Power Control. With multiple control rods withdrawn past position 00, this step requires entry into E0-100-113. Once in this procedure, it is not exited until the Reactor is determined to be shutdown under all conditions without boron. This determination is based on control rod pattern, not actual Reactor power. Reactor power being less than or equal to 5% on APRMs affects the decision on Reactor water level control, but not the decision to exit E0-100-113. With Reactor power less than or equal to 5%, Reactor water level is not required to be intentionally lowered to at least -60". OP-AD-300 directs stabilizing Reactor water level near the current value. A. Incorrect -Although Reactor power is less than 5%, entry into E0-100-113 is still required based on the given control rod pattern. 5% Reactor power is significant as both an E0-100-102 entry condition and a decision point for Reactor water level control in E0-100-113. B. Incorrect - With Reactor power less than or equal to 5%, Reactor water level is not required to be intentionally lowered to at least -60". It is preferred to stabilize Reactor water level near the current value. D. Incorrect - E0-100-113 must be entered based on the given control rod pattern. Reactor power less than 5% allows maintaining Reactor water level in the normal band, but does not allow exiting E0-100-113.

POWER: Cause of partial or complete loss of D.C. power Proposed Question: #78 Both Units are operating at 100% power with the following:

  • Diesel Generator (DG) B is out of service for overhaul.
  • DG E is substituted for DG B.
  • The following conditions for DG E Battery Bank 00595 are reported to the Control Room:

o Float voltage of one connected cell is 2.05 voe. o Float voltage of one pilot cell is 2.09 VDC. o Float current is 2.2 amps. o All other cells tested were within allowable values. Assuming that the above battery conditions CANNOT be corrected, which one of the following describes the latest that the plant can transition to Mode 3, in accordance with Technical Specifications? A. 84 hours B. 86 hours C. 98 hours D. 110 hours Page 6 of57

Proposed Answer: B Explanation: Technical Specification 3.8.6 conditions A, B, and F are entered based upon the initial conditions (connected cell voltage <2.07 voe and float current >2 amps). Condition Fis more restrictive and encompasses both initial conditions of low battery voltage and high float current. This requires declaring the battery inoperable immediately vice having time to correct the issues as in Conditions A and B. The battery is immediately declared INOPERABLE per F.1. Per TS 3.8.4 Condition F, once the battery is declared INOPERABLE, 2 hours is allowed to declare the EOG INOPERABLE. Once the EOG is declared INOPERABLE in TS 3.8.1 Condition B, 72 hours is allowed to restore the EOG to OPERABLE status, or be in Mode 3 in 12 hours. This allows a total of 86 hours before needing to be in Mode 3 (2+72+12=86 hours). A. Incorrect -A total of 86 hours is allowed. 84 hours would be the answer if the 2 hours of TS 3.8.4 Condition E were not factored in. C. Incorrect -A total of 86 hours is allowed. 98 hours would be the answer if only float current were out of spec (>2 amps). However, the addition of a cell <2.07 voe requires a more restrictive shutdown time.

0. Incorrect - A total of 86 hours is allowed. 110 hours would be the answer if only cell voltage was out of spec (>2.07 VOC). However, the addition of float current >2 amps requires a more restrictive shutdown time.

Proposed Question: #79 Unit 1 is operating at 100% power with the following:

  • At 1530, an un-isolable steam leak occurs in the Turbine Building.
  • Operators manually scram the Reactor and enter E0-100-102, RPV Control.
  • The blowout panels open and OSCAR is evaluating the release.
  • At 1550, the combined Noble Gas SPING data is indicated to be 2.3 E8 µCi/min, steady.
  • Reactor conditions are as follows:

o Containment Rad reading is 5 R/hr, steady. o "A" MSL CANNOT be isolated. o Reactor pressure is 900 psig, down slow. o Reactor water level is 40", steady. o RCIC is injecting. Which one of the following describes proper control of Reactor pressure while waiting for Offsite Dose Calculations, in accordance with the Emergency Operating Procedures? A. Maintain pressure between 800 and 1050 psig. B. Open SRVs to cooldown at a rate less than 100°F/hr. C. Open Turbine Bypass Valves irrespective of the cooldown rate. D. Open all ADS valves to perform an Emergency RPV Depressurization. Page 8 of57

Proposed Answer: B Explanation: Entry is required into E0-100-105, Radioactivity Release Control, due to Noble Gas SPING >the Alert level in Table 11 (2.0 E8 µCi/min). With Noble Gas SPING stable well below the GE level (6.2 E9 µCi/min), Emergency RPV Depressurization is neither currently required nor anticipated. E0-100-102 requires Reactor pressure to be lowered, but the cooldown rate maintained below 100°F/hr. SRVs are preferred over Turbine Bypass Valves in this situation to minimize radioactivity release. A. Incorrect - Upon initial entry into E0-100-102, the direction is to stabilize Reactor pressure

   <1087 psig and the normal control band initially given is 800-1050 psig. However, further direction in E0-100-102 directs lowering Reactor pressure with a cooldown rate of
   <100°F/hr. Maintaining Reactor pressure in a higher band is specifically undesirable in this situation since it raises the radioactivity release rate from an un-isolable steam leak outside of primary and secondary containments.

C. Incorrect-With Noble Gas SPING stable well below the GE level (6.2 E9 µCi/min), Emergency RPV Depressurization is neither currently required nor anticipated. E0-100-102 requires Reactor pressure to be lowered, but the cooldown rate maintained below 100°F/hr. If release rate was near or approaching the GE level, then pressure could be lowered irrespective of the cooldown rate. D. Incorrect - With Noble Gas SPING stable well below the GE level (6.2 E9 µCi/min), Emergency RPV Depressurization is not currently required. SRVs are a proper method of pressure control, but not all ADS valves can be opened without violating cooldown rate.

Proposed Question: #80 Unit 1 is operating at 5% power with the following:

  • A loss of coolant accident occurs.
  • Operators manually scram the Reactor.
  • Following the scram, all offsite power is lost.
  • RHR and Core Spray pumps automatically start.
  • HPCI starts and then trips.
  • RCIC starts and is injecting.
  • ADS has failed to initiate.
  • Reactor water level is -178", down slow.
  • Reactor pressure is 700 psig, down slow.

Which one of the following describes the appropriate action to be taken, in accordance with the Emergency Operating Procedures? A. Enter E0-100-112, Emergency RPV Depressurization.

8. Enter the Steam Cooling section of E0-100-102, RPV Control.

C. Reset the Main Generator lockout and inject with Condensate pumps. D. Rapidly depressurize the Reactor using Turbine Bypass Valves per E0-100-102, RPV Control. Page 10 of57

Proposed Answer: A Explanation: With Reactor water level below -161" and almost to -179" with injection subsystems lined up (RHR and Core Spray), E0-100-102 step RC/L-17 requires entering E0-100-112, Emergency RPV Depressurization. Note: The question meets the KIA because Reactor pressure is high with respect to the capacity of available injection systems and the LOCA mitigation strategy in a low power I shutdown situation is tested. B. Incorrect - Steam Cooling would only be entered if no injection source was available. While Reactor pressure is currently too high for RHR and Core Spray to inject, they are still available to inject following an Emergency RPV Depressurization and therefore counted towards the number of available injection systems. C. Incorrect - If offsite power were available, then resetting the Main Generator lockout and injecting with Condensate would be a viable option for restoring and maintaining Reactor water level above -161". However, since all offsite power has been lost, Condensate pumps are unavailable for injection. D. Incorrect- Rapidly depressurizing the Reactor with Turbine Bypass Valves to get within the capacity of low pressure injection systems would have been a viable option earlier in the accident. However, the conditions have degraded to the point where an Emergency RPV Depressurization is required, not just anticipated. Additionally, MS IVs are currently closed due to plant conditions.

D. 2300 the next day. Page 12 of57

Proposed Answer: D Explanation: Technical Specification 3.6.2.1 Condition entry is not required while RCIC is operating (adding heat to the Suppression Pool) since Suppression Pool average water temperature remains below limits of 105°F, 110°F, and 120°F. However, once heat addition to the Suppression Pool is terminated at 2300, Technical Specification 3.6.2.1 Condition A must be entered since Suppression Pool average water temperature is above 90°F. Required Action A.2 allows a maximum of 24 hours from this time to restore Suppression Pool average water temperature to less than or equal to 90°F (2300 the next day). A. Incorrect - The latest time allowed is 2300 the next day. 1030 the next day would be the answer if the completion time for Technical Specification 3.6.2.1 Condition B were applied from the time Suppression Pool average water temperature first reached 90°F. B.

Proposed Answer: B Explanation: ON-143-001 entry is required based on both degrading Main Condenser vacuum (rising Turbine back pressure) and abnormally rising Offgas flow. Due to the degrading Main Condenser vacuum, ON-143-001 requires a Reactor power reduction per G0-100-012 to maintain Turbine exhaust pressure exceeds the limits of Attachment E. With a Main Generator load of approximately 36% and exhaust pressure of 4.5" HgA, operation is outside the alarm curve (orange) of Attachment E. Since operation is only above the orange curve, neither a Reactor scram nor a Turbine trip are required. The operator has 5 minutes in this region before they must trip the main turbine A. Incorrect- Since Condenser vacuum is continuing to degrade, ON-143-001 requires lowering Reactor power. C. Incorrect - Since operation is currently within the limits of ON-143-001 Attachment E, a Reactor scram is not yet required. D. Incorrect - Since operation is currently within the limits of ON-143-001 Attachment E, continued Reactor and Turbine operation are allowed for 5 minutes . It is plausible at low power levels to be able to rapidly lower Reactor power such that the Turbine can be tripped without scramming the Reactor.

Proposed Answer: D Explanation: The given conditions result in an Emergency Classification of Site Area Emergency (FS1 - Loss or Potential Loss of Any Two Barriers; loss of Primary Containment barrier and potential loss of RCS barrier based on high area temperature and rad level with un-isolable RCIC leak). The elevated radiation levels in Reactor Building Zone 1 with positive differential pressure means an unmonitored airborne release is occurring from the Reactor Building due to the event. Note: Table F-1 Row E in the provided reference to the applicants will be blocked out to prevent Question #93 from being a direct lookup. A. Incorrect - The potential loss of the RCS barrier by itself would result in an Alert, however the additional loss of the Primary Containment barrier requires a Site Area Emergency.

  • A malfunction with Instrument Air Dryer C is causing high differential pressure across the dryer.
  • Attempts to shift to Instrument Air Dryers A and B have been unsuccessful.
  • Instrument Air pressure is 100 psig, steady, on Pl-12511A.
  • Instrument Air header pressure is 88 psig, down slow, on Pl-12564.
  • Annunciator AR-107-G01, SCRAM PILOT VALVE AIR HEADER LO PRESS, is in alarm.
  • Scram Air header pressure is 64 psig, down slow.

Which one of the following describes the cross-tie that is required to restore Instrument Air header pressure with the given malfunction and the need to direct a Reactor scram? Cross-tie of ... A. Service Air to Instrument Air will restore Instrument Air header pressure. Directing a manual Reactor scram is required now. B. Service Air to Instrument Air will restore Instrument Air header pressure. Directing a manual Reactor scram is NOT required now. C. Unit 2 Instrument Air to Unit 1 Instrument Air will restore Instrument Air header pressure. Directing a manual Reactor scram is required now. D. Unit 2 Instrument Air to Unit 1 Instrument Air will restore Instrument Air header pressure. Directing a manual Reactor scram is NOT required now. Page 25 of57

Proposed Answer: c Explanation: ON-118-001 contains steps regarding both cross-tie of Service Air to Instrument Air and Unit 2 Instrument Air to Unit 1 Instrument Air. A significant difference between these lineups is that Service Air inputs upstream of the Instrument Air Dryers, while Unit 2 Instrument Air inputs downstream of the Instrument Air Dryers. With the Air Dryers being the source of the issue, cross-tie of Service Air will NOT be able to restore pressure, while cross-tie of Unit 2 Instrument Air will be able to restore pressure. The conditions requiring a Reactor scram in ON-118-001 are NOT yet met, however AR-107-G01 does require a manual Reactor scram to be directed due to low Scram Air Header pressure. Note: The question meets SRO level guidance in NU REG 1021 because the second half of the question cannot be answered solely by knowing systems knowledge, immediate operator actions, AOP/EOP entry conditions, or overall purpose, sequence of events, or overall mitigative strategy of a procedure. While the requirement for a manual Reactor scram on low Instrument Air header pressure is an immediate operator action (RO level knowledge in ON-118-001), the requirement for a manual Reactor scram on low Scram Air Header pressure is not an immediate operator action, and requires SRO level knowledge of the specific requirements of AR-107-G01 for transitioning to ON-SCRAM-101, Reactor Scram. Therefore the question does require the candidate to assess plant conditions (Instrument Air header pressures, Scram Air Header pressure) and determine specifically when one procedure (AR-107-G01) requires implementation of another procedure (ON-SCRAM-101 ). A. Incorrect - Service Air inputs upstream of the Instrument Air Dryers. Therefore with the Air Dryer malfunction, Service Air will NOT restore pressure. B. Incorrect - Service Air inputs upstream of the Instrument Air Dryers. Therefore with the Air Dryer malfunction, Service Air will NOT restore pressure. The conditions requiring a Reactor scram in ON-118-001 are NOT yet met, however AR-107-G01 does require a manual Reactor scram to be directed due to low Scram Air Header pressure. D.

NOT being exceeded. may be maintained at the current value. Page 28 of57

Proposed Answer: B Explanation: With Suppression Pool water level at 16.5', the Core Spray Vortex Limit is approximately 5800 gpm. Therefore, the current Core Spray flow of 7500 gpm is exceeding the Core Spray Vortex Limit. However, E0-100-102 does not require lowering Core Spray flow. The Vortex Limit should be observed when possible, however the need for Core Spray injection to maintain adequate core cooling is of greater concern since Reactor water level is below the top of active fuel (-161") and stable with no other injection systems available. Note: The question meets SRO level guidance in NUREG 1021 because the second half of the question cannot be answered solely by knowing systems knowledge, immediate operator actions, AOP/EOP entry conditions, or overall purpose, sequence of events, or overall mitigative strategy of a procedure. An RO would be required to understand the given Vortex Limit and that pump flow should generally be maintained below the limit, but it is SRO level knowledge to specifically apply the related EOP requirements to a specific situation with competing priorities. In this question, the status of adequate core cooling and available injection systems must be assessed in order to determine the proper control of Core Spray flow per the EOPs. A. Incorrect- E0-100-102 does not require lowering Core Spray flow. The Vortex Limit should be observed when possible, however the need for Core Spray injection to maintain adequate core cooling is of greater concern since Reactor water level is below the top of active fuel (-161 ") and stable with no other injection systems available. C. Incorrect-With Suppression Pool water level at 16.5', the Core Spray Vortex Limit is approximately 5800 gpm. Therefore, the current Core Spray flow of 7500 gpm is exceeding the Core Spray Vortex Limit. E0-100-102 does not require lowering Core Spray flow. The Vortex Limit should be observed when possible, however the need for Core Spray injection to maintain adequate core cooling is of greater concern since Reactor water level is below the top of active fuel (-161") and stable with no other injection systems available.

Level SRO Tier# 2 Group# 1 KIA# 211000 2.4.6 Importance Rating 4.7 SLC Knowledge of EOP mitigation strategies. Proposed Question: #88 Unit 1 has experienced a failure to scram with the following:

  • Initial A TWS power was >5%.
  • Reactor water level has been intentionally lowered.
  • Reactor water level is being controlled between -11 O" and -60".
  • Reactor pressure is being controlled between 800 and 1050 psig.
  • Based on the rate of control rod insertion, it is expected that E0-100-113, Level/Power Control, will be exited in two hours.
  • The Unit Supervisor has directed boron injection using Standby Liquid Control (SBLC) in accordance with OP-153-001, Standby Liquid Control System.
  • Initial SBLC tank volume is 1800 gallons.

Which one of the following describes the approximate time after SBLC initiation at which enough boron will be injected such that it is allowed to commence Reactor depressurization, in accordance with E0-100-113 and OP-153-001? A. -24 minutes

8. -34 minutes C. -42 minutes D. -45 minutes Page 30 of57

Proposed Answer: c Explanation: If any boron is injected, E0-100-113 requires injection of the Cold Shutdown Boron Weight (1650 gallons) before allowing depressurization of the Reactor. OP-153-001 section 2.2 and Attachment A provide the direction for injecting boron with the SBLC system. These procedures direct injecting with one SBLC pump. This provides approximately 40 gpm of flow. Therefore, it will take approximately 42 minutes to inject 1650 gallons of boron solution into the Reactor. Note: The question meets SRO level guidance in NUREG 1021 because the second half of the question cannot be answered solely by knowing systems knowledge, immediate operator actions, AOP/EOP entry conditions, or overall purpose, sequence of events, or overall mitigative strategy of a procedure. The candidate must know the specific details of the EOP mitigative strategy to know when Reactor depressurization is allowed under failure to scram conditions in order to correctly calculate the answer. The candidate must also assess plant conditions (status of Reactor, status of SLC) and select when the next section of the EOP may be used (Reactor depressurization). This includes knowledge of the decision point for when to depressurize. A. Incorrect - It will take approximately 24 minutes to inject Hot Shutdown Boron Weight into the Reactor (932 gallons). B. Incorrect - It will take approximately 34 minutes to inject 1350 gallons into the Reactor. This is the Tech Spec limit for 12% concentration and amount to be operable. D. Incorrect - It will take approximately 45 minutes to inject the entir contents of the SBLC tank volume which is the requirement to secure SBLC pumps in E0-100-113.

Proposed Answer: D Explanation: With the given leak, entry will be required into E0-100-103, Primary Containment Control, due to low Suppression Pool water level, and E0-100-104, Secondary Containment Control, due to high Reactor Building Area water level. E0-100-103 Table 18, Supp Pool Equalization Levels, identifies the expected value at which Suppression Pool water level will stabilize given a leak from various systems. With an un-isolable leak from RCIC, Suppression Pool water level will be maintain at or above 19.5'. Since Suppression Pool water level remains above 17', E0-100-103 will require neither a Reactor scram nor isolation of HPCI. Since Suppression Pool water level remains above 12', E0-100-103 will not require an Emergency RPV Depressurization. Only one Reactor Building Area water level will exceed the Max Safe level and the leak is coming from a non-primary system. Therefore E0-100-104 will require neither a Reactor scram nor Emergency RPV Depressurization. A. Incorrect - A Reactor scram is not required by E0-100-103 because Suppression Pool water level will remain above 17'. A Reactor scram is not required by E0-100-104 because the leak is not from a primary system. B. Incorrect -A Reactor scram is not required by E0-100-103 because Suppression Pool water level will remain above 17'. A Reactor scram is not required by E0-100-104 because the leak is not from a primary system. Isolating HPCI is not required by E0-100-103 because Suppression Pool water level will remain above 17'. C. Incorrect -A Reactor scram is not required by E0-100-103 because Suppression Pool water level will remain above 17'.

TS 3.3.5.1 Condition Entry TS 3.5.1 Condition Entry A. Required Required B. Required NOT required C. NOT required Required D. NOT required NOT required Page 36 of57

Proposed Answer: B Explanation: CST level is below the value (40.5") in TS Table 3.3.5.1-1 function 3.d and the HPCI pump suction has failed to swap from the CST to the Suppression Pool. This requires entry into TS 3.3.5.1 Condition D. Condition D allows up to one hour before declaring HPCI inoperable, which would then require TS 3.5.1 Condition entry. Manually swapping the HPCI suction from the CST to the Suppression Pool in this hour would eliminate any future need to declare HPCI inoperable and TS 3.5.1 Condition entry. Additionally, TS 3.5.1 bases state, "The suppression pool provides the required source of water for the ECCS. Although no credit is taken in the safety analyses for the condensate storage tank (CST), it is capable of providing a source of water for the HPCI and CS systems." Therefore, direct TS 3.5.1 Condition entry is not required based on low CST water level. A. Incorrect - TS 3.5.1 bases do not require TS 3.5.1 Condition entry on low CST water level and TS 3.3.5.1 Condition D allows more time before declaring HPCI inoperable, therefore TS 3.5.1 Condition entry is not required. C. Incorrect- CST level is below the value (40.5") in TS Table 3.3.5.1-1 function 3.d and the HPCI pump suction has failed to swap from the CST to the Suppression Pool.
