ES-401 Sample Written Examination Form ES-401-5 Question Worksheet the TO CA Pump (B&C SG Only) are open, steam flow will also increase.
OP-MC-STM-IDE (p15) states that limit switches provide control room indications when individual steam dump valves are fully open or closed. Both lights will be lit when valve is modulating.
OP-MC-STM-IDE (p27) states that the C-9 interlock blocks steam dump to the condenser if vacuum is low or there is insufficient circulating water flow. The LOOP will stop RC Pumps and cause Condenser Vacuum to be lost blocking Steam Dump operation.
A. Incorrect. SG PORVs are open causing Steam Flow indication (See B).
This is plausible because the operator may believe that the Steam Flow transmitters are downstream of the SG PORVs.
B. Correct. C-9 has blocked the Steam Dump operation, and the Steam Dump Valve position indicating lights will be green (Closed). However, the SG PORVs are set to automatically open at SG Pressure of 1125 psig. Tavg is higher than Tsat of the SG and therefore the SG PORVs will still be open causing steam flow indication on all four SGs (See above).
C. Incorrect. While steam flow will be indicated due to the open SG PORVs (See A), C-9 has blocked Steam Dump Valves from opening. This is Plausible if the operator does NOT recognize that C-9 has blocked Steam Dump System operation.
D. Incorrect. While steam flow will be indicated due to the open SG PORVs, C-9 has blocked Steam Dump Valves from opening. This is Plausible if the operator does NOT recognize that C-9 has blocked Steam Dump System operation.

Proposed Question: Common 42 After a transient from 100% power, the following conditions exist on Unit 1:
- =
NC System pressure Containment Pressure.
- Containment Radiation Monitors in Alarm .
- All systems operated as designed.
Which ONE (1) of the following is an expected response, AND the basis for the response, of the Containment Isolation System?
A. ONLY Phase A Containment Isolation has actuated to ensu re that the NCPs will be available later to mitigate the consequences of this event.
B. ONLY Phase A Containment isolation has actuated to ensure that all penetrations that were open directly to the Containment Atmosphere are now isolated.
C. Both Phase A and Phase B Containment Isolation have actuated to ensure isolation of non-ESF related Containment piping penetrations ONLY.
D. Both Phase A and Phase B Containment Isolation have actuated to ensure isolation of ALL Containment piping penetrations.
Proposed Answer: C Explanation (Optional):
A. Incorrect. Both phases actuate (See C below) . The distractor is plausible because it recognizes that Phase B actuation limits/prevents NCP Operations. However, the NCPs will NOT be needed to support subsequent operations in a Large Break LOCA, but rather, the Small Break LOCA.
Page 106 of271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet B. Incorrect. Both phases actuate (See C below). While it is true that Phase A isolates all penetrations that open directly to the Containment Atmosphere (i.e. VP) , Phase B also actuates.
C. Correct. Section 6.2.4 of the McGuire UFSAR states that the Containment Isolation Systems provide a means of isolating fluid systems that pass through the Containment penetrations to confine radioactivity released during a DBA to the Containment. Section 6.2.4.1.2 of the McGuire UFSAR states that "Upon receipt of either a phase A (ST) Containment Isolation signal which is derived from the Safety Injection signal or a phase B (Sp)
Containment Isolation signal which is derived from the high-high Containment Pressure signal, the Containment Isolation System closes fluid line penetrations not required for ESF operation. In other words , all non-essential lines are isolated to ensure that Containment Leakage is prevented . With the stated conditions , a Safety Injection signal (Ss) will have occurred causing the Phase A signal. Because of the Large break LOCA conditions, Containment Pressure would be > 3 psig (high-high Containment Pressure) causing the Phase B signal. Both Phase A and B actuate to prevent Containment leakage.
D. Incorrect. Containment Phase A and B actuations close CIVs, they do not close all valves in all piping penetrations into and out of the Containment (i.e. ECCS piping which provide flowpath to inject FWST water into the reactor have valves that auto open under these conditions) .

auto reactor trip has failed Page 109 of271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet Proposed Answer: B Explanation (Optional):
A. Incorrect. P-7 Status light will be DARK if P-10 is LIT (2of4 PR >10%) OR P-13 is DARK (1of2 TIP> 10%). In this case, P-7 is DARK because P-10 is LIT indicating PR >10%. If P-10 is LIT, power level cannot be < 10%.
B. Correct. P-7 is Dark indicating power level (Nuclear or Turbine) is> 10%.
When P-7 actuates (DARK) the lower power trips are NOT blocked which means that among others the low NC System flow trip is active at 2of4 logic. Since only one NCP has tripped the required logic for an automatic trip does NOT exist.
C. Incorrect. P-7 is Dark indicating power level (Nuclear or Turb ine) is> 10%.
However, insufficient logic exists to demand auto trip (2of4).
D. Incorrect. P-8 light is LIT indicating power is < 48%. If power level> 48% ,

Proposed Question: Common 45 Given the following events and conditions:
- Unit 1 is approaching Mode 5.
- NC Cooldown is in progress.
- A Train NO is in the RHR mode.
- A Train KC is in service at maximum design flow.
- A Train RN is in service.
- 1A1 KC Pump breaker trips.
Which ONE (1) of the following describes the effect on the KC and NC System temperatu res?
A. KC is unaffected; NC heats up.
B. KC heats up; NC is unaffected.
C. KC heats up; NC cooldown rate decreases.
O. KC is unaffected; NC cooldown rate is unaffected.
Proposed Answer: C Explanation (Optional):
A. Incorrect. The NCS will not heatup because flow through the NO HX has not changed, and there is still some KC flow going through the HX. KC will NOT be unaffected, there is less flow trying to cool the same flow of NC. It will heat up.
Page 114 of271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet B. Incorrect. The NCS will be affected. There is now less cooling water then there previously was, and the mass flowrate of the NC System has NOT changed. The KC System will begin heating up as there is lessflow trying to cool the same flow of NC.
C. Correct. Previously a cooldown rate was established. The NCS will not heatup because flow through the NO HX has not changed, and there is still some KC flow going through the HX, however the cooldown rate has decreased. The KC System will begin heating up as there is less flow trying to cool the same flow of NC.
D. Incorrect. The NO System maintains a stable system flowrate, cooldown rate is dependent upon cooling system flows (KC/RN).

Proposed Question: Common 48 As stated in ECA-O.O, Loss of all AC Power, which ONE (1) of the following is the basis for NOT depressurizing the S/Gs to less than 110 psig?
To avoid _
A. voiding in the head.
B. an inadvertent criticality accident.
C. nitrogen injection into the NC System.
D. the loss of S/G narrow range level.
Proposed Answer: C Explanation (Optional):
A. Incorrect. While the action of depressurizing the Steam Generators will decrease NC Pressure and subcooling, and it is likely that Reactor Head voiding will occur, the Caution is not provided to alert the operator that depressurization should be stopped. In fact, a subsequent Note is provided, also before Step 26, to alert the operator to the fact that it is probable that voiding will occur, and that the depressurization should not be stopped because of this.
B. Incorrect. While the action of depressurizing the Steam Generators will reduce NC System temperature and add positive reactivity, the Caution is not provided to alert the operator that restart will occur at a specific Steam Generator pressure or corresponding NC System temperature. Rather, subsequent steps (27) are provided for the operator to check if a positive SUR exists, and if so, terminate the depressurization to allow NC System heatup and the addition of negative reactivity.
C. Correct. The Caution in ECA-O.O prior to the performance of Step 26 states Page 122 0[271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet that "Lowering Steam Generator pressures to less than 110 psig will cause injection of CLA N2 into the NC System." The background document (OP-MC-EP-ECA-O) adds that the introduction of N2 into the NC System will impede Natural Circulation in the NC System.
D. Incorrect. While the depressurization will cause narrow range level in the Steam Generators to decrease, the Caution is not provided to alert the operator that the level will be lost at a specific Steam generator pressure.
Rather, a substep of Step 26 is provided to direct the operator to terminate the depressurization if narrow range level drops below 11%, restore level, and then re-initiate the depressurization.

Which ONE (1) of the following will be FIRST to trip the reactor and its basis?
A. OT Delta T trip due to the MSIVs failing closed .
B. High-High SG level trip because the Feedwater Reg Valves fail open.
C. Turbine Trip due to Feed Pump Trip because the Feedwater Reg Valves fail closed .
D. High Pzr Level trip due to the Charging Flow Control Valve failing open with Letdown isolated .
Proposed Answer: C Explanation (Optional):
A. Incorrect. If MSIVs fail closed it could cause a trip on LO-LO SG level or on OTDT due to Tave rising . FRVs failing will cause the trip significantly faster than MSIV failure: Plausible because until a recent mod, the MSIVs did fail close on a loss of VI.
B. Incorrect. Feedwater reg valves fail closed, but plausible because this is the reactor trip mechanism if they did fail open.
C. Correct. Reactor trip will occur due to turbine trip . If fedwater reg valves fail closed , Feed Pumps will trip on high discharge pressure, which directly causes a turbine trip.
D. Incorrect. This would cause a reactor trip, but at a significantly later time than feedwater reg valve failure. Charging flow control valve fails open and letdown isolates on loss of air, so PZR level will be rising Technical AP-22 Background Page 134 of271 Rev Final

Tier # 1 Group # 1 KJA# (E11) G2.1 .23 Importance Rating 4 .3 (Loss of Emergency Coolant Recirculation I Conduct of Operat ions : Ability to perform specific system and integrated plant procedures dur ing all modes of plant operation.)
Proposed Question: Common 55 Unit 1 has experienced a Large Break LOCA inside Containment.
- The 1B NV Pump is NOT available.
- The NO Pumps are NOT available.
- The crew has implemented ECA-1.1, Loss of Emergency Coolant Recirc.
- 1A NV Pump is running at 400 gpm.
- 1A NI Pump is running at 400 gpm .
- 1B NI Pump is running at 400 gpm.
- The Standby Makeup Pump is NOT available .
- The Reactor Trip occurred 31 minutes ago.
You have been directed to determine minimum required SI flow per Enclosure 9, Flow Required to Match Decay Heat, of ECA-1.1 to minimize SI flow while maintaining greater than or equal to the required flow.
Which ONE (1) of the following will result in the LEAST number of running pumps which will satisfy the MINIMUM SI flow requirement?
(Reference Provided)
A. Stop both NI pumps.
B. Stop one NI pump ONLY.
C. Stop the NV pump AND one NI pump.
D. All available pumps must remain running.
Proposed Answer: B Explanation (Optional):
Page 1390[271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet The direction is provided by Step 21 RNO of ECA-1.1. This step would be implemented if Cold Leg recirculation is unavailable, the reactor core is cooled, but sufficient subcooling does not exist to terminate SI flow altogether. In this situation the basis of the step is balancing the need for ECCS flow, and the need to minimize FWST depletion.
Using Enclosure 9, the operator will find the small 3 between the large 10 and 100 on the X axis, and then travel up the vertical line until the curve is intersected. At the intersection point, the operator will read the corresponding value of Minimum SI Flowrate on the Y Axis (==445 gpm). With all three pumps delivering 400 gpm, two of the three will need to remain operating. The lowest volume pump should be selected to remain operating. The 1A NV Pump should be maintained operating because seal flow should be maintained to the NCPs, and the Standby Makeup pump is unavailable. At least one of the two NI pumps will be required to remain operating. The remaining pump(s) should be stopped.
In this case either 1A or 1B NI Pumps should be stopped .
A. Incorrect. This will create a situation where there is insufficient SI flow for the stated conditions. 445 gpm of 81 flow is required , and stopping both the 1A and 1B NI Pump will leave SI flow only from the 1A NV Pump at 400 gpm.
B. Correct. (See above).
C. Incorrect. This will create a situation where there is insuff icient SI flow for the stated conditions. 445 gpm of SI flow is required , and stopping the 1A NV Pump, and either the 1A and 1B NI Pump will leave SI flow only from the 1A NV Pump at 400 gpm .
D. Incorrect. This response does not follow the direction to stop one or more pumps.

B. Damage to a Fuel Assembly wh ile being lifted or lowered .
C. Failure of the KF System.
D. A Cavity Seal Failure.
Proposed Answer: B Explanation (Optional):
A. Incorrect. NAC-UMS FSAR indicates that total loss of air flow for periods of days, rather than minutes will cause fuel damage. If applicants believes that loss of convection cooling to the dry storage canister would cause fuel damage in the 30 minute time it lost cooling flow. Per the FSAR, pg 11.1.4-1, it would take longer than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before approaching temp limits. ).
Plausible if the applicant thinks that 2 trains are always running during refueling or if he thinks level is too low.

ES-401 Sample Written Examination Form ES-401-5 Question Worksheet (1EMF 17) in alarm is an identified.
B. Correct. According to the AP25 Background document, inadvertent lifting of a fuel assembly is a common cause (refer to IN 80-01 and IN 86-58) because in a lot of cases the assembly ends up in an unintended location, which can result in striking objects. Dropping an assembly is also a fairly common cause (refer to IN 80-01).
- c. Incorrect. Only 1 train is needed due to heat load (FH-KF, page 43). KF failure is plausible if applicant thinks that level is too low.
D. Incorrect. Pool level is above normal (KF, pg 27 Low flow through demineralizer means less clean up of activity. Low level could mean less scrubbing of volatile activity. Symptom of AP25, Spent Fuel Damage. SFP Level is normal. If Cavity Seal Failure, level would be going down if KF-122 is open.

The indications provided indicate that an actual fire event is taking place at the 1B NC Pump (Zone 148 Alarm - RCP 1B Motor). The mitigation strategy will be handled by addressing AP45, and dispatching the Fire Brigade into the Containment.
Page 157 of271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet A. Incorrect. The purpose of AP8 is to ensure proper response in the event of a malfunction of an NC pump and to identify the appropriate actions in the event of an NC Pump Seal or Pump Lower Bearing Malfunction, an NC Pump Motor or Motor Bearing Malfunction, or Excessive Vibration. While the event may degrade to these types of problems, the entry conditions are not yet met. The distractor is plausible because the fire event is associated with the 1B NC Pump motor, and the operator may believe that this is a result of a malfunction of the 1B NC Pump.
B. Incorrect. The purpose of AP24 is to describe steps to be taken to achieve and maintain Hot Standby following a fire event that results or could result in a loss of plant control from the Control Room or Aux Shutdown Panel.
This procedure will also be used following security events that could result in a loss of plant control from the Control Room or Aux Shutdown Panel.
This procedure will also be used when referenced by any procedure that requires plant shutdown using the SSF. While the event may degrade to these types of problems, the entry conditions are not yet met.
C. Correct. AP45 provides guidance to mitigate the effects of a fire that has the potential of causing loss of control of safeguards systems during MODEs 1-3. It will send the operator to an Enclosure based on the determination of an active fire, and then identify vital equipment within the area, and steps that must be taken to protect the equipment.
D. Incorrect. Both of these procedures are inappropriate (See A and B).

Proposed Question: Common 66 After two hours into a shift on Unit 1, the OATC reviews the Control Room Unit Log and identifies the following :
- A plant transient occurred on the previous shift.
- A momentary entry into a Technical Specification Action Statement occurred.
- The event was NOT logged .
- No TSAIL entry was made.
Which ONE (1) of the following describes the MINIMUM required course of action?
A. The CRSRO makes a TSAIL entry, and then clears the entry because the condition no longer exists. The CRSRO makes the correction to the previous shift's log.
B. The OATC makes a follow-up entry in the current shift's log explaining the situation. A TSAIL entry is NOT required.
C. The CRSRO makes the correction to the previous shift's log. A TSAIL entry is NOT required.
D. The OATC makes the TSAIL entry, and then clears the entry because the condition no longer exists. The CRSRO follows up with an entry in the current log .
Proposed Answer: B Explanation (Optional) :
A. Incorrect. Section 7.2 of OMP 5-2 states that entry into a TS Action Statement for which a TSAIL entry will NOT be made requires entry into the Control Room Unit Log. If conditions no longer exist, then TSAIL entry will not be required Page 168 of271 Rev Final
ES-401 Sample Written Examination Form ES-401-5 Question Worksheet B. Correct. Section 6.4 of OMP 5-2 states that the OATC can make Control Room Log entries. Section 6.15.2 of OMP 5-2 states that editing of archived logs should NOT normally be done. Rather, errors in archived logs should be explained in follow-up entries in current active logs.
C. Incorrect. Section 6.12 of OMP 5-2 states that log archiving is to take place in the first 15 minutes of the shift. Therefore, the previous shift logs are archived logs. Section 6.15.2 of OMP 5-2 states that editing of archived logs should NOT normally be done.
D. Incorrect. TSAIL entry is not required, and OATC would not perform that action if it was required.
