2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 8 Answer 6. Cold leg injection flow is decreased due to the filling operation. is also correct. Cold leg flow would decrease while the Accumulator fills. When opening a parallel flow path, flow in the first flow path must go down.
The supplied Engineering Calculation/Evaluation also concludes that, Pump run out should not be a concern for parallel pump operation if a Large Break LOCA were to occur during accumulator fill.
- 2. Resolution and Response The question is correct as written.
The question will be changed prior to entry into the bank to clarify the given condition for the design basis LOCA. A condition will be added that following initiation of the LOCA SI Pump B fails to start and CANNOT be started manually.
The calculation is correct with two SI Pumps running, however, the question premise provides the following condition, A Design Basis LOCA occurs. The question first gives that SI Pump A is running. USAR Section 14.3.2 describes the Major RCS Pipe Ruptures (LOCA), and subsection Performance Criteria for ECCS describes the ECCS systems response. On page 14.3-8 the following information is provided to define the design basis LOCA.
For the Best-Estimate large break LOCA analysis, one ECCS train, including one high head safety injection (HHSI) pump and one RHR (low-head) pump, starts and delivers flow through the injection lines. One branch of the HHSI injection line spills to the containment backpressure; the other branch connects to the intact loop cold leg accumulator line. The RHR injection line connects directly into the upper plenum. Both emergency diesel generators (EDGs) are assumed to start in the modeling of the containment fan coolers and spray pumps. Modeling full containment heat removal systems operation is required by Branch Technical Position CSB 6-1 (Reference 14) and is conservative for the large break LOCA.
The Technical Specification basis also supports the question as written. TS 3.3.b.5 provides protection from the possibility of one SI pump reaching runout condition during SI accumulator fill concurrent with a large break LOCA. CAPO28956 documents the reason the step 4.3.5.f and h, for entering and exiting a l-hour LCO to fill an SI Accumulator was added to procedure A-SI-33, Abnormal Safety Injection Accumulator Level and Pressure. This CAP references LER 97-004, which was submitted to report the existence of an unanalyzed condition during SI Accumulator filling operations. Specifically, if a LOCA occurred while filling an SI Accumulator, applying single-failure criteria to the Safety Injection pumps could result in only one SI pump delivering flow to both the RCS and the accumulator being filled, and a single SI pump providing flow to both the RCS and an accumulator could be subject to runout, which would result in no operable SI pumps during the accident.
Page 1
2006 Kewaunee NRC Retake Written Examination Question Feedback Concerning the reduction in SI flow, the amount of water being injected to the RCS would be reduced by the amount being diverted to the accumulator. However under the design basis accident, RCS pressure would be at Containment atmospheric pressure. With a maximum value of 46 psig for this pressure, the water flowing to the Accumulator would still be directed to the Cold Leg via the Accumulator outlet. If the flow indication (F1925) were assumed to the operator to be observed indication of Cold Leg Injection flow, then it would rise since the Accumulator fill line is downstream of the flow indicator.

- 1. Examinee Feedback Question Number 19 There is no correct answer. E-0 step 5 does not direct you to check the SI ACTIVE Status Panel at this point. Step 17 has you check these items, and has you manually align those items.
- 2. Resolution and Response The question is correct as written.
The use of alternate indications for status verification is supported by Site and Operations standards.
Dominion Nuclear Operations Standard, DNOS - 0302, Control Board Monitoring, provides the following Expectation, Operators monitor control board indications closely to detect problem situations early. The Standard states, in part, The OATC (operator at the controls) shall use all direct and alternative indications for verification of status.
GNP-03.30.02, Conduct of Operations, Rev. E, also supports the above by reference to the expectations and standards for control board monitoring contained in DNOS - 0302.
Step 5, sub-step c states, FW-12A and B, Feedwater To Steam Generator A(B) Isolation Valves - CLOSED. The Contingency Action sub-step c states, Manually close the valves. BKG E-0 describes actions as, Determine if the valves are closed and close valves as necessary.
Also the instrumentation given is Position indications for these valves.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 25 Accept D as correct answer.
Answer A will cause an SI thus emergency boration will not be required. That leaves answer D as the correct answer.
- 2. Resolution and Response Accept either answer A or D as the correct answer.
Rewrite question to include conditions that has SI Block active in selection A, or remove question from bank.
Not enough information in either the stem or selection A to preclude the assumption that a Safety Injection is NOT actuated due to the condition. Based upon the given information, Selection A with given indications could result in Safety Injection actuation on low Przr pressure (less than 1830 psig) or low steamline pressure (less than 514 psig). This would provide the necessary boration via SI Pump injection into the RCS, rather than by direction of E-CVC-35. The progression through the IPEOPs will be from E-O, Reactor Trip and Safety Injection, to E-2, Faulted Steam Generator Isolation, if the SG pressure is still dropping at step 23 of E-0; or to ES-1.1, SI Termination, at step 26 of E-0 if the btowdown of the SG is complete or stopped by the time step 23 of E-0 is reached.
In E-2, Faulted Steam Generator Isolation, steps wilt be taken to isolate the affected SG and transition would be made to E-1, Loss of Reactor Or Secondary Coolant, at step 9 of E-2. In E-l, Loss of Reactor Or Secondary Coolant, transition to ES-1.1, SI Termination, would be made at step 12, if conditions supported, or by direction of E-1 QRF (Quick Reference Foldout), item 1, SI Termination Criteria. If conditions did not support SI termination, then the transition would be made to ES-1.2, Post LOCA Cooldown And Depressurization, at step 18.b of E-I.
In ES-1.2, Post LOCA Cooldown And Depressurization, charging pumps are started and aligned to the RWST, and then at step 6 RCS cooldown to Cold Shutdown is initiated. In NOTE 1 prior to this step reads, NOTE: During the RCS cooldown, RCS Boron Concentration should be monitored to verify Cold Shutdown Boron Concentration per RD-6.7.
ES-1.1, SI Termination, also directs starting of charging pumps, but directs establishing normal charging and letdown. ES-1.I step 12 has the operator set makeup for automatic control with the Boric Acid Controller set to 11.O. The operator is directed in ES-1.I step 25 to establish stable plant conditions, which includes maintaining RCS temperature at existing value. This would place the plant in INTERMEDIATE SHUTDOWN. ES-1.1 then directs the operator to go to the appropriate Plant Procedure, which would be N-0-05, Plant Cooldown from Hot Shutdown to Cold Shutdown Condition. N-0-05, step 4.1.I and 4.1.2 direct the operator to determine the Cold Shutdown boron concentration and borate the RCS to this value.
Page 4
2006 Kewaunee NRC Retake Written Examination Question Feedback However, in both circumstances, the boration is performed using the normal boration controls for the Reactor Makeup Control System. Therefore, emergency boration is not used.
Selection D is definitive in its conditions and requires an emergency boration to the Hot Shutdown boron concentration. This emergency boration is the largest amount required (648 gallons) from the remaining selections.
Selection A remains an acceptable answer if it is assumed an SI does not occur. This is plausible if based on conditions as allowed in procedures (N-RC-36C, steps 4.2.7.8.b and 4.4.3 when RCS pressure is below 2000 psig and Safety Injection is blocked (Pressurizer SI Blocked). In this case SI would not occur and the appropriate action would be emergency boration. This emergency boration would require 241 6 gallons to reach the Cold Shutdown boron concentration.

All of the given monitors will indicate the release of activity from the B steam generator.
- 2. Resolution and Response The question is correct as written.
In A, R-36 is a high-range monitor for the Aux Building Stack; In 6 and D, R-34 is a high-range monitor for the steam line from SG B.
Both R-34 and R-36 have a sensitivity of 1 Whr with an indicated range of 1 Whr to 10,000 Whr.
With a leak of 10 gpm, the expected radiation indication would range about several mWhr at the main steamline. This is about one one-hundredth the sensitivity of the detectors and would not be expected to be displayed for the monitors.

- 1. Examinee Feedback Question Number 55 Answer A is also correct. No timeframe was given for the question. CVC-11 fails closes.
- 2. Resolution and Response Accept either *A or D as correct.
The question does not provide the time frame for selecting the answer. CVC-11 does have an air accumulator in its supply line and will remain in its current position for a period of time.
However, if air is not restored the accumulator will become depleted and CVC-11 will fail closed.
The line for CVC-11 is a 2 line and the bypass line containing CVC-13 and CVC-14 is a % line.
The purpose of CVC-14 is to provide a relief path due to differential pressure in the line upstream and downstream of the regenerative heat exchanger when CVC-11 is closed. The reduction in flow when CVC-11 closes would be apparent to the operator. Running this condition on the simulator shows that the bypass line only passes approximately 0.6 gpm for F1128 (node point measurement on bypass line). This is below the accuracy of FI-128 meter, so for the operator flow goes to zero. The seal injection pathway flow provides the other flow path for charging.

+ When ES 87128 is in REMOTE, CVC-7 is controlled using Control Station CS 4320301 in the Control Room.
Charging flow through CVC-7 is sensed by Flow Element FE-128 and indicated locally and in the Control Room. FE-128 is located upstream of CVC-7, but downstream of where seal water injection taps off. Therefore the Control Room Operator must compensate when comparing charging and letdown flow since some of the seal water injection will return to the RCS via the RXCP labyrinth seals.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 75 No correct answer. In the given conditions, SI has occurred. This starts all 4 fan coil units. No indication that any have been secured. Step 2 of FR-Z.3 has you verify fan coil units are running. The answer is yes, thus you do not Start containment fan coil units... They are running.
- 2. Resolution and Response The question is correct as written.
The premise does not provide the status of the Containment Fancoil units; however, there is nothing that precludes the units from being stopped or not running at this point in the procedure.
The correct action is to verify they are running and if not start the Fancoil Units. If the situation was that the Fancoil Units are always running after SI and continued to run at this point, there would be no need for the Contingency Action statement. The correct action is to start the Fan Coil Units for the purpose provided.
Question could be improved by changing Start... to Verify Containment Fancoil Units running... In this case by definition, verify means check running and if not running start.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 78 The question does not take into consideration the full effects of the Bus 6 lockout outside of Bus
- 62. On a bus 6 lockout from 100% power, the secondary plant transient would lead to a condition that would require a reactor trip to place the unit in a safe condition. The loss of power to Bus 6 has various effects but most notably at 100% power are the loss of both Heater Drain Pumps and the loss of Service Water Train B.
Both Heater Drain Pumps are lost due to de-energization of MCC-62C and MCC-62E, leading to the loss of power to the Heater Drain Pump magnetic couplings and de-coupling. Per A-CD-03, the loss of two Heater Drain Pumps requires turbine impulse pressure to be reduced to less than or equal to 425 psig or approximately 70% using VPL Lower to maintain adequate suction pressure to the Main Feedwater Pumps. This is not accounted for in the question considering the stem has the plant at 97% following the transient which is not possible based on the previous discussion.
Additional consideration needs to be made based on the loss of Service Water. The Bus 6 lockout causes Service Water Pumps 1 B1 and 1 B2 to be lost due to the loss of power. Header pressure would be expected to drop to less than 72 psig in the B header quickly closing SW-3B if not already closed (in-plant condition). With the Turbine Building SW Selector Switch in the B position, all Service Water flow would be lost to the Turbine Building. Temperatures on various equipment and components such as Feedwater and Condensate Pump bearings and slot gas temperatures would rise very quickly. Temperature limits would be exceeding requiring equipment stopped/tripped within a matter of minutes including a trip of the main turbine. At the onset of the transient the following procedures need to be addressed A-CRD-49, A-EHV-39, A-SW-02, A-CD-03, and various other abnormals associated with high temperatures on equipment in the Turbine Building. During review and performance of the listed procedures trip criteria would be met prior to opening of SW4A in A-SW-02 which is late in the procedural actions.
Therefore, based on the above discussion, the loss of Bus 6 puts the unit in a transient that is more severe than is stated in the question. Based on actual plant performance and response, the trip of the unit is the correct conservative response to make given this situation.
Answer C is correct.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 2. Resolution and Response There is no correct answer.
The question is to be deleted from the exam.
The loss of the Heater Drain Pumps was not addressed in development, review or validation of the examination, only the affect on IRPls (rod indication). The action is correct to reduce load in accordance with A-CD-03, Condensate System Abnormal Operation. The plant would not be stabilized at 97% power; therefore, the premise of the question is invalid. This makes the question incorrect. As stated above, A-CD-03 requires with no Heater Drain Pump running that turbine load be reduced to less than or equal to 425 psig impulse pressure, or approximately 72% power.
The loss of Service Water is not considered since the question does not specify the Turbine Building SW Header is selected to either train. Assumption that the Turbine Building SW Header is aligned to Train B is not prudent since the header is just as likely to be aligned to Train A.
This should have been addressed during the examination as a question on alignment of SW.
C cannot be a correct answer. Even if the reactor is tripped due to the given conditions, the emergency boration of 360 gallons for each control rod is not required. This makes the selection also incorrect.

- 1. Examinee Feedback Question Number 80 Not enough information. If the recirculation fluid temperature and pressure exceed design conditions, then answer D is correct.
- 2. Resolution and Response The question is correct as written.
The premise that the feedback addresses is based on the precaution and limitation from the system normal operating procedure, N-RHR-34, Residual Heat Removal System Operation.
This P&L is applicable to normal operation conditions only. The conditions given in the question is post-accident. Thus the limitations for the systems are the design limits. Consideration must be then given to RHR, SI and Containment Spray systems that may be supplied on recirculation flow. From the USAR the following design values are:
Desiqn Temperature Desiqn Pressure RHR Pump 4OOOF 600 psig (also for valves & pipes)
RHR Hx SI Pump 3OOOF 2485 psig ICs Pump 3OOOF 500 psig 400° (tube) / 35OOF (she11)600 psig (tube) / 150 psig (Shell Based on the accident analysis the maximum expected Containment Sump temperature is approximately 280OF. This correlates to a maximum Containment pressure of 46.0 psig. These valves fall within the acceptable design limits for the associated systems that may receive the recirculated fluid under accident conditions. As shown by the graph, the actual temperature in the Containment Sump at the time ES-1.3 is being performed (approximately 20 minutes following the initiation of the accident) will be closer to 25OOF (maximum). This is confirmed in USAR Table 6.2-1 2 that gives 25OOF as the maximum operating conditions for RHR components during post LOCA recirculation.

- 1. Examinee Feedback Question Number 85 Answer A is correct based on procedure use and adherence rules. E-EDC-38A Symptoms Section 2.1 lists 47101-A, DC VOLTAGE LOW, as an entry condition for procedure. Procedure E-EDC-38A may be implemented due to a symptom being met, therefore answer A is correct.
- 2. Resolution and Response The question is correct as written.
The single symptom, BRA-102 DC VOLTAGE LOW (47101-A), is not indicative of a loss of power to BRA-104, which is the purpose of E-EDC-38A. It would not be appropriate to perform E-EDC-38A for these conditions. The Alarm Response Procedure in and of itself directs, GO TO A-EDC-38.
Other than the first Subsequent Action of E-EDC-38A, 4.1, Contact Plant Electricians to investigate cause for loss of power, the remaining steps of E-EDC-38A address actions for systems lost or affected by the loss of DC. These do not address the conditions provided in the premise. A-EDC-38, which also has the same symptom, does directly address actions to address the specific conditions by investigating and checking local indications and components.
The UG-0 provided section on Procedure Entry refers to dual-column format procedures only, as indicated by the hierarchy.

- 1. Examinee Feed back Question Number 86 Following establishment of Bleed and Feed, the PORV relieving to the PRT causes the rupture disc to rupture. It is anticipated that Containment may reach Adverse Conditions of 4 psig. Step 27 of FR-H.l has criteria for a hot, dry SG at 5% [20% for Adverse]. In either case this is met and FW flow should be limited to 60 to 100 gpm until level is greater than 5% [20% Adverse].
Levels per the question are 2% and 3%. Answer A is correct.
- 2. Resolution and Response The question is correct as written.
Hot Dry SG conditions do exist. However, with the RCS temperatures rising, the urgency of establishing a heat sink predominates, and full feedwater flow should be established to one SG.
As indicated in the BKG FR-H.1,...it is advisable to reestablish feedwater to only one steam generator regardless of the size of the plant or number of loops. Thus, if a failure occurs due to excessive thermal stresses, the failure is isolated to one steam generator.
This last statement makes A incorrect since it establishes flow to both SGs.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 91 Answer A is correct. The premise of the question states that SP-36-082 is completed with a leak rate of 1.1 lgpm of total RCS leakage. Also given are the combination of the RXCP annunciator and RCDT level change both of which are indicative of a Number 2 Seal issue on the B RXCP. Using the provided Operator Aid the leakage from the Number 2 seal can be calculated to be approximately 0.75gpm. (change of the last hour minus normal leakage based on RCDT level change or 0.8 gpm - 0.04gpm = -0.75 gpm) This leakage is now considered identified leakage. It is known where it is coming from, that it is contained, and that it is within the limitations of the RCDT. Being that the total leakage identified by SP-36-082 was 1.1 lgpm and 0.75gpm has been determined to be identified leaves the remaining 0.36gpm as unidentified. Technical Specifications allows not in excess of 1 gpm unidentified leakage and not in excess of 10 gpm identified leakage. Neither of these thresholds have been met. Therefore no actions are required since unidentified leakage remains less than lgpm per Technical Specifications.
- 2. Resolution and Response Accept either A or B as correct.
Rewrite question to specify that only the mass balance leakrate calculation (of SP-36-082) has been completed per section 6.1, and has the following value of 1.1 1 gpm.
The premise does state, SP-36-082, Reactor Coolant Leak Rate Check, has just been completed. The intent of this was to signify that the Mass balance Leakrate Calculation had been completed. In this event, the investigation is required. This was apparent during development, review and validation, since no comments were received that disputed the selected correct action.
However, the statement in the premise can be interpreted to mean the entire procedure is complete, which includes section 6.3, the Investigation and Evaluation. If this is performed and the RCDT level change is attributed to the RXCP #2 seal problem, then no other action is required. Data Sheet 4, INVESTIGATION AND EVALUATION, would have been completed to describe the source of the leak, the effect on plant operation and the determination the plant operation may safely continue. This also agrees with the actions of A-RC-36C, Attachment b, Response to Abnormal #2 Seal Leakoff, with #2 seal leakoff flow greater then 0.5 gpm but less than 1.1 gpm.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 95 Accept D as a correct answer.
N-FH-53CLD, Refueling Daily Checklist, has you check R-12 operating. If the Checklist or an item on the Checklist is not verified, you cannoffshould not move fuel. The action is conservative.
- 2. Resolution and Response Accept either C or D as correct.
Either remove the question from the bank or change selection D to be an incorrect action.
The ODCM requires either R-12 or R-21 to be OPERABLE and addresses action for a purge in progress, but does not specifically address Fuel Handling. Likewise the normal procedure N-RM-45, Radiation Monitoring System, addresses the removal of R-12 from service, and ensuring R-21 is operating and aligned to sample the appropriate location.
Using Conduct of Operations and the Standard DNOS - 0101 for Nuclear Safety and Conservative Decision Making, it is not unreasonable to stop fuel movement while verifying the status of required components. The operations guidance for fuel handling, N-FH-53-CLC, Pre-Refueling Checklist, and N-FH-53-CLD, Refueling Daily Checklist, both require R-12 and R-21 to be operating during fuel movement. There is no specific guidance on actions to take if one of the monitors fails. Therefore, Conservative Decision Making is applied, and fuel movement should be stopped. This is also supported by the General Notes of RF-03.01, Fuel Movement During a Refueling Outage, 2.7 which states, in part, Each member of the refueling team needs to understand that they have the authority to stop refueling activities to resolve an issue.

6.0 Procedure 6.1 Nuclear Safety And Conservative Decision-Making 6.1.1 The expectations for Nuclear Safety And Conservative Decision-Making are contained in DNOS-0101, Nuclear Safety And Conservative Decision-Making.
6.2 Human Performance - Self-Checking (STAR) 6.2.1 The expectations for Self-checking are contained in DNAP-1907, Human Performance (HU) Program.
6.3 Human Performance - Peer-Checking 6.3.1 The expectations for Peer-Checking are contained in DNAP-1907, Human Performance (HU) Program.
6.3.2 Additional requirements for peer-checking are:
6.3.2.1 6.3.2.2 6.3.2.3 6.3.2.4 6.3.2.5 The SM or US shall assess the complexity or the importance of task performance to determine peer checker qualifications. The peer checker shall have sufficient knowledge to evaluate the task in progress and is knowledgeable of the peer checking process.
Peer-checking requires the performance of the action to be observable and methodical in the actions being taken, with discrete pauses to allow observers to correct any errors.
Peer-checking never relieves an Operator from the responsibility to self-check, nor the responsibility for achieving the desired outcome of the action being taken.
Peer-checking is encouraged but not required for all Control Board manipulations.
When the pace of activities increases to the point where obtaining a peer check constitutes a distraction in itself, operators and supervisors shall remain aware of the need to prevent operational events by increasing the attention paid to other error prevention techniques, such as use of STAR.
Peer-checking is required for all reactivity manipulations, except during seIected activities where it is not practical (e.g., rapid power reductions, or transients, etc.).
The peer check requirement may be waived only with concurrence of shift supervision.
INFORMATION USE
DNOS - 0101 Revision 0 DOMINION NUCLEAR OPERATIONS STANDARD NUCLEAR SAFETY AND CONSERVATIVE DECISION MAKING Expectation :
9 Nuclear and industrial safety are the overriding station concerns.
> The reactor and its supporting systems are maintained within the bounds of analyzed equipment alignments and approved procedures.
3 Risks and challenges associated with plant operations are anticipated and a healthy respect is maintained for the stored energy within the reactor core.
> Operators faced with unexpected or uncertain conditions will place the plant in a safe condition and will not hesitate, if necessary, to reduce power or trip the reactor.
Standards:
3 9
9 3
9 9
9 P
Operators shall recognize when degraded conditions exist that could challenge plant safety or reliability.
Information shall be gathered and analyzed from relevant sources and appropriate personnel in order to clearly define and provide options for resolution of operational concerns.
Short-and long-term risks, consequences, and the aggregate impact associated with decision options shall be critically and objectively considered.
Implementation plans to resolve operational concerns shall be developed that include contingencies and compensatory measures to maintain or enhance safety or probabilistic risk margins.
Decision-makers and their roles and responsibilities shall be clearly identified.
Command and control responsibilities shall be carried out in accordance with sitespecific procedures.
The bases for decisions shall be communicated throughout the organization.
The effectiveness of decisions shall be periodically evaluated.
Human performance tools and group input shall be utilized to avoid inappropriate actions and unexpected responses when reaching operating decisions.
When faced with time-critical decisions, operators:
+
Do not allow production or cost to override safety.
+
Do not challenge the safe operating envelope.
+
Question and validate available information.
+
Utilize available alternate indications to validate information.
+' Assume the available indications are valid until proven otherwise.
Use all available resources, including people offsite, if necessary.
+
Develop contingency actions, if time allows.
+
Do not proceed in the face of uncertainty.

2.0 General Notes 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Contact the Reactor Engineering Group (RXE) for resolution of any problems, concerns, or questions.
Signoffs in this procedure shall be M E unless identified otherwise or unless designated by the RXE.
Working copies of this procedure may be used to facilitate fuel movement and signoffs may initially be made in the working copies. However, signoffs are to be transferred to the master copy as soon as practical.
During performance of this procedure, the master copy of all forms in this procedure (FAHDR, FAMS, ICRR) shall be retained in the control room. The containment and spent fuel pool copies shall be maintained for informational purposes only.
Operations (OPS) (SRO), Chemistry, and Quality Control (QC) work groups are needed to support performance of this procedure.
During refueling operations, the big picture must be kept in focus at all times. Care must be taken to NOT fixate on only one solution to a probledissue encountered during fuel movement. The entire refueling team should be included in all problem solving and the problem observed from as many directions and angles as possible prior to deciding on and implementing a solution. The Management team needs to be kept informed of the same.
During refueling operations, schedule pressure needs to be conservatively managed. The time required to refuel the reactor safely, successfully, and error free is the correct duration. Each member of the refueling team needs to understand that they have the authority to stop refueling activities to resolve an issue. Only the Refueling SRO shall restart refueling activities.

2006 Kewaunee NRC Retake Written Examination Question Feedback
- 1. Examinee Feedback Question Number 98 Answer B is correct answer. When DG is started it is done per A-DGM-1 OB, and Bus 6 is energized per step 4.6. Step 4.6.4 states Sequentially start safeguards equipment as required.
This guidance can be used to start the SI Pump B. No conflicting guidance is given in ECA-0.0.
- 2. Resolution and Response The question is correct as written.
Step 7 of ECA-0.0 directs the operator to place specific equipment in PULLOUT, including the SI Pumps. A NOTE prior to step 9 (Dispatch personnel to locally restore Emergency AC Power) reads. Pre-planning of power restoration efforts based on the event and available sources is required. When power is restored to the Bus the operator is directed to continue actions of ECA-0.0 at step 37. Three CAUTIONS exist prior to step 38. The two applicable CAUTIONS read, The loads placed on the energized emergency AC Bus should not exceed the capacity of the power source, and, If an SI signal exists or if an SI signal is actuated during this procedure, it should be reset to permit manual loading of equipment on an emergency AC bus. At step 40, the operator transitions to the appropriate recovery procedure (ECA-0.2 in this case).
The NOTE at the beginning of the procedure states (Likewise in ECA-O.O), CSF Status Trees should be monitored for information only. Function Restoration Procedures should not be implemented prior to completion of Step 10. At step 5 in ECA-0.0, the operator is directed to manually load safeguards equipment on AC Emergency Bus, including SI Pumps.
BKG ECA-0.0 specifically states in 1. Introduction, If plant conditions have deteriorated significantly, the operator may have insufficient or conflicting indications as to plant status and a concurrent event may be contributing to the deterioration of RCS conditions. Under these RCS conditions, the operator is instructed to implement IPEOP ECA-0.2 and initiate plant recovery utilizing Safety Injection (SI) operational systems. IPEOP ECA-0.2 functions to start safe-guards equipment as appropriate and then directs the operator to go to IPEOP E-1...)

The loss of all ac power procedures are unique within the IPEOP set. With the exception of these procedures, all IPEOPs are written on the premise that at least one ac emergency bus is energized and associated equipment can be powered from the energized ac emergency bus. Consequently, the guidance provided in other procedures in the IPEOP set is not applicable following a loss of all ac power. Therefore, ECA-0.0 has priority over all other procedures in the IPEOP set.

Following restoration of ac power, the operator is instructed to stabilize steam generator pressures, if secondary depressurization is in progress, and to evaluate the status of the energized ac bus. These actions verify that certain select equipment has automatically loaded on the ac emergency bus and provides the operator with information that will aid him in loading subsequent equipment on the energized ac emergency bus in recovery procedures.
Step 6 CAUTION 1 (for the transition to step 37) basis reads To minimize the deterioration of plant conditions, recovery actions should be started as soon as ac power is restored. Procedure ECA-0.0 is written such that recovery actions step can be entered from any step that follows this CAUTION.
Procedures ECA-0.0, ECA-0.1 and ECA-0.2 are written to establish the appropriate systems operation and alignments before transitioning the operator to other IPEOPs.
UG-0, Users Guide For Emergency and Abnormal Procedures, sets the priority for implementing procedures. Section 6.2 identifies the general order of priority: 1) FRPs; 2) ORPs;
- 3) EOPs and 4) AOPs. As mentioned above ECA-0 series is special in that it takes priority over FRPs. In this case the direction of ECA-0 series should take the highest priority in actions to be performed.
The action in B will start the SI Pump without having a Component Cooling Water Pump running for support.
