61. You are the Unit 1 Unit Supervisor and have been informed by the RO of the problem with SOP-104A which was stated in an earlier question (SOP refers to 1/2-MU instead of 1/1-MU). For each of the actions listed below, explain why each would or would not be correct and choose the best action for this situation: [Ref: STA-201, STA-202, ODA-407] a. N/A the step and allow performance of the next step. b. Use N/A to allow proceeding using the 1/1-MU handswitch. c. Process an Interim Approved Change to correct the procedure before continuing. d. Make an Editorial Change to the procedure before continuing. e. Make a One Time Procedure Change to allow proceeding until the procedure can be formally changed. f. Use the normal change process to change the procedure before continuing. g. Identify the need for a procedure change, authorize proceeding and process the change when time allows.
As follows: a. No. N/A should NOT be used to bypass steps that are inadequately or improperly written or otherwise be used in lieu of an approved change. In addition, the step is critical to proper task completion. b. No. N/A does not mean a step can be changed. N/A only allows not using a step if it meets N/A criteria. c. Yes. The procedure methodology is not as it should be. The procedure should be changed before dilution is performed. An Interim Approved Change may be performed, instead of the normal procedure change because the evolution needs to be performed soon. The normal procedure change process requires more extensive approval than the interim change. The interim change only requires approval of a knowledgeable member of operations staff and either the Shift Manager or Unit Supervisor. d. No. The change from 1/2-MU to 1/1-MU does not meet the strict criteria of STA-202 for editorial changes. e. No. A One Time Change doesn't allow for a faster or less-reviewed change. It exists to allow changes to a procedure for one use to address a unique set of circumstances without permanently changing the procedure and then having to change it back. f. Yes. This method is allowed and generally preferred. However, since this method also requires Operations Manager approval, it may be more expeditious to use the Interim Approved Change Process. g. No. The only time this latitude is given is in implementation of ERGs and ABNs and in those cases you must follow guidance given for an ERG/ABN deviation.
90. With Unit 1 operating at power, 1-HV-5545, Containment Air Radiation Monitor Supply Isolation Valve is determined to be failed open. What action should be taken? [Ref: ODA-308, Technical Specifications]

Close 1-HV-5544 in-line with the failed penetration isolation and make clearance tied to LCOAR to keep it in this position (within 4 hours, 3.6.3 Condition A) • Enter LCO for TS 3.3.6, "Containment Ventilation Isolation Instrumentation" and 3.4.15 "Leakage Detection Systems." Close and maintain closed 1-HV-5548 and 1-HV-5549, Containment Pressure Relief Isolation Valves. • Enter LCO for TS 3.4.15., "Leakage Detection Systems" for loss of air particulate monitoring capability. Establish grab samples or perform RCS water inventory balance per OPT-303 once per 24 hours.
92. Unit 2 is at 75% RTP when all DRPI bezel indication goes dark. What action is required? [Ref: ABN-712, Technical Specifications]
Attempt to shift power supplies per SOP-608B. If bezel indication is not restored, initiate repairs per STA-606. Place Rods in Manual, monitor and record RCS Tavg once per hour, verify rod position indirectly by using core power distribution measurement information once per 8 hours and within 4 hours if rod movement >24 steps and restore within 24 hours.
65. How can you, as Shift Manager, know that a test procedure does not constitute a test or experiment not described in the safety analysis? [Ref: STA-707, 10CFR50.59]
By using your judgment based on training and experience and by ensuring the test is properly approved. The evaluation (screening) which is performed as part of the approval process for any procedure addresses the issue of whether or not it is described in the FSAR and whether prior approval must be granted by the NRC or a license amendment is required.
1. Define the term "continuous use." [Ref: STA-201]
CONTINUOUS USE of a procedure or work instruction is required for complex or infrequent work activities for which consequences of an improper action could have an immediate, possibly irreversible adverse impact on safety, production, or reliability.
18. Which log is used to record common unit operations? [Ref: ODA-104]

Control board status aids should be updated to reflect the current plant component's status, as applicable, upon completion of any realignment when the associated system is in service.
45. What is the definition of "core alteration?" Identify specific activities or manipulations that should and should not be considered core alterations. [Ref: RFO-102, Technical Specifications]
Core alterations shall be the movement of any fuel, sources, or reactivity control components, within the Reactor vessel with the vessel head removed and fuel in the vessels. Suspension of CORE ALTERATIONS shall not preclude completion of movement of a component to a safe position. The following items have been discussed as to whether they do or do not constitute a CORE ALTERATION per Technical Specifications. The following items are considered as "Core Alterations": • RCCA Unlatching (including RCCA drag testing) • Upper Internals Lift • Fuel Movement • RCCA Latching (including RCCA drag testing) • These items should NOT be considered "Core Alterations": • Reactor Vessel Head Removal • Positioning Underwater Lights • Positioning Underwater Cameras • Movement of fuel loading shoehorns and cables • Moveable Incore Thimble Tubes (Removal or Replacement) • Post Core Load Verification • Upper Internals Replacement • Removal of Reactor Vessel Test Capsule with fuel installed in the vessel
76. Whose approval is required to perform troubleshooting on an operating safety related component? [Ref: STI-606.05 STATION TROUBLESHOOTING ACTIVITIES]
If prepared by on-shift Operations personnel, it should be reviewed and approved by the Shift Manager. Implementation is approved by the US or Shift Manager as appropriate. If prepared by other groups the RWO manager preparing the plan must concur and approval by an SRO. If technical specification or safety related equipment is involved the plan content must receive concurrence from the Shift Operations Manager. Implementation approval is as stated above.
74. Define "defense in depth" as it applies to plant status during outages. [Ref: STA-627, STI-604.04]
Defense In Depth (DID) - For the purpose of managing risk during shutdown, Defense In Depth is the concept of: Providing systems, structures, and components to ensure backup of Key Safety Functions using redundant, alternate, or diverse methods. Planning and scheduling outage activities in a manner that optimizes safety system availability. Providing administrative controls and contingency plans that support and/or supplement the above elements ultimately resulting in a reduction of the probability of a core-damage event during a planned outage. STI-604.04, "Outage Safety Function Guide" (OSFG) establishes the desired level of Defense In Depth.
100. Define the following: [Ref: STI-211.06] a. Annual Limit on Intake (ALI) b. Derived Air Concentration (DAC) c. Threshold Limit Value (TLV)
Definitions: 1. Annual Limit on Intake (ALI) - The derived limit for the amount of radioactive material taken into the body of an adult worker by inhalation or ingestion in a year. ALI is the smaller value of intake of a given radio nuclide in a year by the reference man that would result in a committed effective dose equivalent of 5 rem or a committed dose equivalent of 50 rem to any individual organ or tissue. 2. Derived Air Concentration (DAC) - The concentration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work results in an intake of one ALI. 3. Threshold Limit Value - There are three (3) categories of Threshold Limit Values (TLVs) which are defined as follows: • Threshold Limit Value - Time Weighted Average (TLV-TWA) - The time weighted average concentration for a normal 8-hour work day and a 40 hour week to which nearly all workers may be repeatedly exposed, day after day, without adverse effect. • Threshold Limit Value - Short Term Exposure Limit (TLV-STEL) - A 15-minute weighted average exposure which should not be exceeded at any time during a work day even if the 8 hour TWA is within the TLV. Exposures at the STEL should not be longer than 15 minutes and should not be repeated more than four times per day. There should be at least 60 minutes between successive exposures at the STEL. • Threshold Limit Value - Ceiling (TLV-C) - The concentration that should not be exceeded even instantaneously.
49. Place the following steps in the correct sequence: • Remove upper internal package • Flood cavity to 858'2" • Unlatch control rods • Place reactor vessel head on storage stand • Isolate dilution paths [Ref: RFO-102]
Dilution paths must be isolated prior to Mode 6 entry (vessel head detensioned). Cavity flood is started after the initial head lift but the reactor vessel head is normally placed in the storage stand before the cavity reaches 858'2" to minimize time that the load is suspended. Control rod drive shafts are unlatched after head removal and flood up to about 858'2" elevation but before removal of the upper internals package. (5, 3, 4, 2, 1)
77. What issues should be considered when using procedure sections to perform troubleshooting? [Ref: STI-606.05 STATION TROUBLESHOOTING ACTIVITIES]
Exercise caution when using procedures or procedure sections that were not specifically written to cover the activity being performed, i.e., systems are operated to OPTs, SOPs, or ABNs. If troubleshooting would result in operation outside of these procedures or if the intent of the procedure is not the same as the intent of the activity being performed, then write a temporary procedure or PCN an existing procedure to cover the activity. Steps written in a work order cannot be used to change or allow deviation from a procedure during troubleshooting of in-service equipment.
55. List some indications and controls on Unit 1 control boards which are not duplicated on Unit 2.
Indications on Unit 1 boards only: • DWST level • BAST levels • Instrument Air Compressor X-01, X-02 lights • Hydrogen purge exhaust fan controls

Flash Protection Boundary - An approach limit at a distance from an exposed live part within which a person could receive a second degree burn if an electrical arc flash were to occur. Limited Approach Boundary - An approach limit at a distance from an exposed live part within which a shock hazard exists. A non-qualified person cannot cross the limited approach unless under the direction of a qualified person. Restricted Approach Boundary - A shock protection perimeter that can only be crossed by qualified persons knowledgeable in the use of shock protection techniques, tools, and equipment.
78. A valve motor operator torque switch has been adjusted under a work order. What general types of test(s) should the work order direct Operations Department to perform prior to declaring the valve operable? [Ref: Post Work Test Guide]
Functional stroke test for position indication, exercise test, stroke time test, as-left Appendix J LLRT for Containment isolation valves, boundary valve leak test for RCS boundary isolation valves.
41. RCS dissolved hydrogen is determined to be 20 cc/Kg while operating at power. Determine the Action Level and required actions. [Ref: STA-609]
Hydrogen concentration below 25 cc/Kg (but >15) places the plant in Action Level 1. Initiate actions to restore to within optimized value of 25 to 50 cc/Kg within 7 days. Note that the exception to permit operation > 15 cc/Kg but < 25 cc/Kg for up to 24 hours without entering Action Level 1 only applies for the initial period after startup.
34. While performing a system lineup at the end of an outage, you discover the position indicator broken on one of the valves to be aligned. If you can determine by other means that the valve is correctly positioned, what action should you take regarding the lineup and the valve position indicator? [Ref: ODA-410]
If time permits, have the Prompt Team or appropriate Smart Team repair the problem. If the valve can be ascertained to be in the proper position and functional by other plant indications (flow, temperature, etc.) and it cannot be repaired prior to the need to close out the line-up, then document the problem (e.g., write a CR).
98. You, a qualified Radiation Worker, are walking through the Auxiliary Building and notice a container collecting leakage from a system is overflowing. The container is inside an area marked off as a contamination area and fluid is leaking outside the boundary. The liquid has pooled outside of the roped-off area and the container is still leaking. What should you do? [Ref: STA-653]
Inform the Control Room by gaitronics or telephone. Inform others to stay away. Don gloves and booties and use materials found in spill kits, if available, to limit the spread of contamination and to direct leakage to a floor drain, if possible.
93. Inverter IV2EC3 develops an internal fault and output breakers trip open and the associated instrument bus de-energizes. What actions are required? [Ref: Technical Specifications, ODA-308]
Initiate repairs. Enter LCO for TS 3.8.9, "Distribution Systems - Operating." Restore power to 2EC5 within 2 hours from bypass power. Align the panel 2EC5 to IV2EC1/3 per SOP-607B within 24 hours. NOTE: ODA-308-3.8.9 requires Condition D to be entered or a risk evaluation to be performed if the panel will be operated on bypass power for greater than 16 hours
50. What indications should be monitored while inserting a new fuel assembly into the core? [Ref: RFO-401, RFO-102]
Monitor the following during fuel assembly insertion: a) SR NIs should be monitored in Control Room to verify reactor remains subcritical (during CORE ALTERATIONs). b) The weight indicator should be continuously monitored to see that the indicated weight does not drop below the combined weight of the gripper mast, fuel assembly and insert assembly. A weight drop could indicate binding on other assemblies.
81. What time is used as the LCO initiation time? [Ref: ODA-308]
LCOAR Initiation Time - The time at which it is determined that a LCO is not satisfied (Active LCOAR) or when a LCO is impacted (Tracking LCOAR). This initiation time may be any of the following: • The time of discovery of a clearly adverse condition affecting OPERABILITY, OR • The time of notification to the Shift Manager that a Quick Turnaround Technical Evaluation (QTE) has determined that a component is inoperable, OR • The time at which the allowable surveillance interval expired in accordance with Technical Specification SR 3.0.3. When it is discovered that a surveillance has not been performed within its specified frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours OR up to the limit of the specified frequency, whichever is greater. However, a risk evaluation shall be performed for any Surveillance delayed greater than 24 hours and the risk impact shall be managed. Also, the SR 3.0.3 Bases states the missed surveillance should be performed at the first reasonable opportunity. The delay period is permitted to allow performance of the surveillance inaccordance with SR 3.0.3.
86. When do we declare entry into MODE 2? [Ref: IPO-002A/B]
MODE 2 entry is declared upon withdrawal of Control Bank A rods during a startup. This declaration is made after Control Bank rods have been fully withdrawn and reinserted to CBO to reference and offset rod banks. The declaration of MODE 2 occurs before TS conditions for MODE 2 are actually met.
85. What is the formal definition of MODE 2? [Technical Specifications]
MODE 2 is defined as the inclusive combination of reactor power < 5% and keff > 0.99.
87. When do we declare entry into MODE 6 from MODE 5? [Ref: RFO-102]
MODE 6 entry from MODE 5 is declared at the time de-tensioning of head bolts is initiated.
71. What reference is available to identify the test procedure which is used to meet a given surveillance requirement? [Ref: STA-702]
Maximo, and the Operation's Web Page. In Maximo, select Locations, then References. The test procedure(s) that satisfy the surveillance requirement will be listed under "Other Related Items". From the Ops Web Page, the information can be found under the Component Information tab. Select Component Detail, the Surveillance Detail field will list the associated test procedures.
5. A delta-I swing is in progress. As the RO monitoring the situation you decide it is time to perform a dilution and to insert rods 2 steps to dampen the oscillation. Do you have the authority to perform these activities without informing your Unit Supervisor? Why or why not? [Ref: ODA-102]
No - ODA-102 requires the RO to "Inform the Unit Supervisor prior to any dilution, boration, rod movement, or turbine load changes. Include the magnitude and direction (for rods and turbine load) of change."
91. 1-HV-5545, Containment Air Radiation Monitor Supply Isolation Valve is failed open. A spurious reactor trip occurs. The cause of the trip has been determined and corrected. Assuming 1-HV-5545 is the only inoperable plant component, would you be allowed to restart with this valve out of service? [Ref: Technical Specifications]
No - Technical Specification LCO 3.3.6 would allow conformance to the action requirement of 3.6.3 (affected penetration isolated) and thus allow continued operation of the facility for an indefinite period of time, therefore allowing a MODE change. However, the action statement of 3.4.15 would not. Continued operation with the Containment PIG out of service is allowed provided grab samples are obtained or RCS water inventory balance is performed every 24 hours, but the PIG must be restored within 30 days. A risk assessment in accordance with 3.0.4.b may allow a MODE change as it is not specifically precluded in TS 3.4.15.

No more than 26 hours should be worked in any 48-hour period. If you stay over, you will end up working 27 hours in a 48-hour period. A waiver (STA-615-1) may be authorized provided: • The crew member's absence would cause a violation of minimum manning requirements • No other qualified individual is available to provide coverage • The Operations Shift Manager or site senior-level manager with requisite signature authority determine that a waiver is necessary to mitigate or prevent a condition adverse to safety • A cognizant supervisor completes a face-to-face fatigue assessment no more than four (4) hours prior to the start of the waiver period (extended work hours) • The waiver is approved before the waiver period begins • You must remain in compliance with all other work hour rules (must have a minimum 10-hour break before starting the third day of your scheduled dayshift run). Consequently, another qualified individual must be available to cover at least the first one and one half (1-1/2) hours of your next shift (assume relief arrives at 2100 and complete turnover at 2130).
10. Both units are operating at 100% power. One of the ROs needs tomorrow (a scheduled shift day) off. The crew is operating with four ROs. Can he be permitted to take the day off without scheduling someone else to take his place on shift? [Ref: ODA-102]
No.
2. You are the Unit 1 RO. SOP-104A, "Reactor Makeup and Chemical Control System" has just been revised. You are using the procedure to perform a normal periodic dilution to compensate for fuel burnup when you notice the procedure says, "Place 1/2-MU, RCS MU MAN ACT in STOP." You believe there is a typographical error; the procedure should refer to 1/1-MU vice 1/2-MU. Can you proceed with the dilution? If not, what should you do? [Ref: STA-201]
No. You must stop the task in progress and immediately notify the Shift Manager or Unit Supervisor of your discovery of the procedure error.

13. What activities and events should be announced on the plant gaitronics system? [Ref: ODA-102]
The ODA section on Plant Gaitronics lists the following: • Commencement of a reactor startup or shutdown • Reactor trips or load rejections • Abnormal or emergency conditions • Activation of the E-plan, change in E-plan EAL (emergency action level), site evacuation, a change in the Emergency Coordinator • Starting major plant equipment • Changes in electrical distribution system lineup • Significant changes in radiological conditions
53. The refueling machine operator reports to you, the RO, that a spent fuel assembly has been dropped. Shortly thereafter, PC-11 alarms are received on the Containment PIG monitors. What should you do? [Ref: ABN-908]
The RO should report a dropped fuel assembly to the Unit Supervisor, acknowledge the PC-11 alarms and report them to the Unit Supervisor. These are entry conditions for ABN-908 and should be recognized by the RO. If necessary, the RO should prompt the Unit Supervisor to take ABN-908 actions, including notifying the Shift Manager, making a plant announcement and evacuating Containment, and verifying Containment ventilation isolated.
42. Chloride concentration in Steam Generator blowdown spikes to 600 ppb due to placing a contaminated polisher in service at 100% power. The polisher is immediately removed from service and concentration rapidly decreases to <100 ppb. What additional action(s) should be taken? [Ref: STA-610]
The SG chloride spike places the unit under Action Level 3 criteria, which requires a power reduction to < 5%, regardless of the duration of the excursion and may require a plant shutdown and cooldown based on the recommendation of the Chemistry manager.
68. Who ensures required procedure revisions are approved and ready for implementation prior to installation of the TM? [Ref: STA-602]

The approval authority of the Lessons Learned is the Shift Operations Manager or designee. If the information is of immediate "need-to-know" importance, the approval authority should be the Shift Manager. When that is the case, the Shift Manager should inform the Shift Operations Manager at the earliest opportunity.
47. What is the minimum elapsed time allowed for completion of core off-load following reactor shutdown? [Ref: RFO-102]
The design analysis of the Spent Fuel Cooling Systems assumes that a normal full core off-load starts at 75 hours after the reactor is subcritical and is complete no earlier than 125 hours after the reactor is subcritical (FSAR 9.1.3.1.1). The 125-hour limitation is a conservative value which may be modified by a core-specific offload calculation.
83. What is the basis for maintaining the control rods above the rod insertion limit? [Technical Specifications]
The insertion limits of the shutdown and control rods are initial assumptions in all safety analyses that assume rod insertion upon reactor trip. The insertion limits directly affect core power and fuel burnup distributions and assumptions of available SDM, and initial reactivity insertion rate. Limits on control rod insertion have been established, and all rod positions are monitored and controlled during power operation to ensure that the power distribution and reactivity limits defined by the design power peaking and SDM limits are preserved.
60. Siemens, A.G. publishes a bulletin recommending replacement of the air side seal oil pump's start switch (A ON, B ON, OFF) at the GAC, with one that is "functionally equivalent." How would we determine if this constitutes a change to the facility as described in the FSAR? What CPNPP process would be utilized to make the replacement? [Ref: STA-716, ECE-5.08]
The modification would be reviewed against the requirements of STA-716 and ECE-5.08. A Design Equivalent Change would likely be utilized.

6. How far back in time should you review the unit log when assuming the watch as the Unit Supervisor, the BOP or the RO? [Ref: OWI-107]
The review of Station and Unit Narrative Logs should include a review of the period since the on-coming person's last on-duty shift, not to exceed five days.
84. What is the basis for maintaining average coolant temperature <588 (592)°F? [Technical Specifications]
The safety analyses of normal operating conditions and anticipated operational occurrences assume initial conditions within the normal steady state envelope. The limits placed on RCS pressure, temperature, and flow rate ensure that the minimum departure from nucleate boiling ratio (DNBR) will be met for each of the transients analyzed. The RCS coolant average temperature limit is consistent with full power operation within the nominal operational envelope. Indications of temperature are averaged to determine a value for comparison to the limit. A higher average temperature will cause the core to approach DNB limits.
97. Assuming an individual has received 1200 mrem for the year to date and has no other exposures in excess of routine dose limits, what would the dose limit be for a planned special exposure as a member of a Steam Generator tube plugging team? [Ref: STA-655]
Under a Planned Special Exposure an individual is allowed to receive 4000 mrem for the year due to the Planned Special Exposure if he or she has not had other exposures in excess of routine occupational dose limits. So, for this case the PSE limit would be 4000 mrem.

Urgent (Priority 2) Activities required for maintaining plant reliability, safety issues and longer term Technical Specification Action Statements. The Responsible Manager should ensure work starts within 24 hours and continues daily. SM could assign a Priority 1 based on Regulatory implications of having an inoperable CCP.
35. During power operation, the inlet isolation to the main turbine lube oil temperature control valve is discovered partially closed. In response, the Shift Operations Manager directs the performance of a verification lineup on the turbine plant cooling water system. What is a verification lineup and what valves need to be verified on the lineup? [Ref: ODA-410, Operations Guideline 12]
Verification lineups may be performed at management's discretion if and when the need arises to verify component alignment. Those same lineups initially performed for system operation may be used; however, Verification Lineups do not require independent verification for completion. Verification Lineup attachments need only be completed for flowpath valves. The following valves may be marked N/A (not applicable) during the performance of Verification Lineup attachments at the Shift Manager's discretion. • Vent valves • Drain valves • Test connection valves • Sample valves • Throttle valves during "at power, system in-service" verification lineup
72. When hanging or removing clearances, no SOP is necessarily in use. The clearance hanger only has the clearance package in hand. During this evolution, what controls ensure that equipment is operated in accordance with approved instructions? [Ref: STA-605, STI-605.01]
When the clearance has been prepared, it shall be forwarded to the SRO or cognizant Operations Supervisor in control of the clearance review. 1. The SRO shall provide a supervisory review of the clearance to ensure proper tagging sequence, adequate boundary for personnel and equipment safety and that the necessary plant configuration is maintained on systems defined in STA-601 for Shift Operations responsibility. 2. The SRO shall denote all cleared equipment that requires a Verification prior to releasing the prepared clearance for implementation. (Clearances placed for Technical Specification LCO. requirements or configuration control.) 3. The SRO should determine if other work is to be performed on equipment within the clearance boundary. If the exact clearance boundaries ensure proper safety, other Work Orders may be performed under the same clearance. 4. The SRO should ensure the applicable work order(s) are associated with the clearance. 5. The SRO shall ensure the clearance has been prepared or reviewed by a qualified clearance preparer and then reviewed by an SRO.
8. Both units are operating at full power. The operating crew is composed of the following: (1) SM (3) US (2 are STA qualified) (4) RO (1) FSS (1) RP Tech (1) Chem Tech (8) PEO (1) RW One of the STA qualified Unit Supervisors receives a call that a close family member has a medical emergency. He informs the Shift Manager that he is going home immediately to assist with the emergency. Is this action permissible? How should the Shift Manager respond? [Ref: ODA-102]
Yes, this is permissible and can be classified as the unexpected absence of an onduty crew member. With his absence, the crew complement is one less than the minimum required. The Shift Manager must take immediate action to restore crew complement to minimum within 2 hours.
