WBN 10-2011 NRC SRO Exam As Submitted 811512011 DIS TRACTOR ANALYSIS:
A. Correct, Tech Spec 3.6.6 identifies that while containment spray is required in Mode 4, the RHR spray is not needed to supplement the containment spray and is not required. As the heat up continues to Mode 3, the RHR spray is required and if the valve is not repaired the provisions of LCO 3.0.4.b can be implemented to allow entry into Mode 3.
B. Incorrect, Plausible because no Tech Spec LCO being required while in Mode 4 is correct and since the valve status will prevent meeting the LCO after the mode change. The required actions of LCO 3.6.6 do not permit continued operation in the Mode, thus 3.0.4.a will pre vent the Mode change unless the requirements of 3.0.4.b are met and there are LCOs that will not allow the use of 3.0.4.b.
C. Incorrect, Plausible because Tech Spec LCO 3.6.6 entry would have been required if the RCS temperature had been at least 350°F (Mode 3) and implementing the provisions of LCO 3.0.4. b to allow the Mode change is correct.
D. Incorrect, Plausible because Tech Spec LCO 3.6.6 entry would have been required if the RCS temperature had been at least 350°F (Mode 3) and since the valve status will prevent meeting the LCO after the mode change. The required actions of LCO 3.6.6 do not permit contThued operation in the Mode, thus 3. 0.4.a will prevent the Mode change unless the requirements of 3.0.4.b are met and there are LCOs that will not allow the use of 3.0.4.b.

F. Procedures and limitations involved in initial core loading, alterations in core configuration, control rod programming, and determination of various internal and external effects on core reactivity. [10 CFR 55.43(b)(6)]
Some examples of SRO exam items for this topic include:
Evaluating core conditions and emergency classifications based on core conditions.
- Administrative requirements associated with low power physics testing processes.
o Administrative requirements associated with refueling activities, such as approvals required to amend core loading sheets or administrative controls of potential dilution paths and/or activities.
- Administrative controls associated with the installation of neutron sources.
- Knowledge of TS bases for reactivity controls.
G. Fuel handling facilities and procedures. [10 CFR 55.43(b)(7)]
Some examples of SRO exam items for this topic include:
- Refuel floor SRO responsibilities.
- Assessment of fuel handling equipment surveillance requirement acceptance criteria.
- Prerequisites for vessel disassembly and reassembly.
- Decay heat assessment.
- Assessment of surveillance requirements for the refueling mode.
- Reporting requirements.
- Emergency classifications.
This does not include items that the RO may be responsible for at some sites such as fuel handling equipment and refueling related control room instrumentation operability requirements, abnormal operating procedure immediate actions, etc. For example, an RO is required to stop the refueling process when communication is lost between the control room and the refueling floor, therefore, this is a task that is both an RO and SRO responsibility and is not SRO-only.

WBN 10-2011 NRC SRO Exam As Submitted 811512011 DIS TRACTOR ANAL YSIS:
A. IncorrecI, Plausible because SOI-30.06 being required is correct and ESF actuations are normally reportable.
B. Incorrect, Plausible because performance of a section of SOl-31.02 would be required if the Auxiliary Building isolation had been caused by any of the signals (other than SFP rad monitor) and ESF actuations are normally reportable.
C. CorrecI, SOI-30.06, Auxiliary Building Gas Treatment System would be required to restore the ABGTS fan to a standby alignment and the actuation would be an invalid actuation, thus no 8-hour notification would be required.
D. Incorrect, Plausible because performance of a section of SOI-31.02 would be required if the Auxiliary Building isolation had been caused by any of the signals (other than SFP rad monitor) and ESF actuation not being reportable is correct because the actuation was invalid.

Some examples of SRO exam items for this topic include:
- Evaluating core conditions and emergency classifications based on core conditions.
- Administrative requirements associated with low power physics testing processes.
- Administrative requirements associated with refueling activities, such as approvals required to amend core loading sheets or administrative controls of potential dilution paths and/or activities.
- Administrative controls associated with the installation of neutron sources.
- Knowledge of TS bases for reactivity controls.
G. Fuel handlinc facilities and procedures. [10 CFR 55.43(b)(7)]
Some examples of SRO exam items for this topic include:
- Refuel floor SRO responsibilities.
- Assessment of fuel handling equipment surveillance requirement acceptance criteria.
- Prerequisites for vessel disassembly and reassembly.
- Decay heat assessment.
- Assessment of surveillance requirements for the refueling mode.
- Reporting requirements.
o Emergency classifications.
This does not include items that the RO may be responsible for at some sites such as fuel handling equipment and refueling related control room instrumentation operability requirements, abnormal operating procedure immediate actions, etc. For example, an RO is required to stop the refueling process when communication is lost between the control room and the refueling floor, therefore, this is a task that is both an RO and SRO responsibility and is not SRO-only.

14.0 FIRE PROTECTION SYSTEMS AND FEATURES OPERATING REQUIREMENTS (OR)
The OR established in this section have been developed to ensure adequate fire protection capability is available and maintained, to detect, control, and extinguish fires occurring in any portion of the plant where safety-related or FSSD equipment are located.
Fire protection systems and features at WBN are not assumed to be operable to mitigate the consequences of a Design Basis Accident (DBA) or plant transient. The bases for this assumption are contained in Section I of Appendix R which states that the need to limit fire damage to systems required to achieve and maintain FSSD conditions is greater than the need to limit fire damage to those systems required to mitigate the consequences of DBAs. As a result,Section I identifies that fire protection features must be capable of limiting fire damage so that:
- 1. One train of systems necessary to achieve and maintain hot shutdown conditions from either the control room, auxiliary control room, or emergency control stations is free of fire damage; and
- 2. Systems necessary to achieve and maintain cold shutdown from either the control room, auxiliary control room, or emergency control stations can be repaired within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
- 3. Alternate shutdown capability is provided at WBN, when needed, to achieve and maintain cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
Operability of the fire protection systems and features are required whenever safety-related equipment and fire safe shutdown systems protected by the fire protection systems and features are required to be Operable.
The Fire protection Report provides applicable action statements and thus does not have a requirement similar to Technical Specification 3.0.3 except for equipment listed in Section 14.10. When a piece of equipment in section 14.10 is out of service, there are mode reduction requirements similar to Technical Specification 3.0.3. However, equivalent methods (documented in an engineering evaluation in accordance with site procedures) that ensure fire safe shutdown can be achieved per the requirements of 10CFR50, Appendix R may be used to delay or remove the mode reduction requirements.
These equivalent methods once documented by engineering evaluation provide alternatives to the applicable actions statements when equipment listed in Part II, Section 14.10 must be declared inoperable.
The Fire Protection Report does not have a requirement similar to Technical Specifications 3.0.4 preventing mode changes while in an action statement.
The Testing and Inspection Requirements (TIR5) for the WBN fire protection systems and features have been developed taking into consideration industry practice (e.g., similar methods approved for use by other licensed nuclear power facilities), NFPA consensus standards, and insurance carrier loss prevention recommendations.

PART II - FIRE PROTECTION PLAN Rev. 39 BASES OPERATING REQUIREMENTS (OR)
FIRE SAFE SHUTDOWN EQUIPMENT B.14.10 A minimum set of plant systems and components has been identified at WBN to ensure that the plant can achieve and maintain safe shutdown in the event of plant fires (see Part Ill, Safe Shutdown Capabilities). In the majority of cases the identified plant systems and components are addressed by WBN Technical Specifications and Technical Requirements Manual which list surveillance requirements for verifying the Operability of the systems and components. This OR lists the systems and components which are not included as part of a Technical Specification or Technical Requirement.
Thermal overloads that are by-passed during accident conditions must remain operable during normal plant operation. This will ensure that valves that are required for a Control Building fire are not damaged due to a hot short that could by-pass the torque switch. In addition, the thermal overloads are required for limiting current flow in the event of fire induced multiple high impedance faults and documented in the Multiple High Impedance Fault Analysis. The Technical Requirements Manual, Table 3.8.3-1, Motor-Operated Valves Thermal Overload Devices Which Are Bypassed Under Accident Conditions provides the list of thermal overloads this statement addresses.
This OR is provided to ensure that systems and components which are required for safe shutdown are maintained operable and tested to ensure operability. The intent of this OR is to ensure the equipment listed in Table 14.10 is capable of performing its FSSD function. To ensure this, equipment listed in Table 14.10 shall satisfy the FSSD Condition listed by being Operable, capable of achieving its FSSD Condition, or in its FSSD Condition. The equipment listed in Table 14.10 is considered inoperable when it is not in or can not achieve its listed FSSD Condition. The actions are based on Technical Specifications 3.3.4, Remote Shutdown System.
B.14.10.1 With a safe shutdown component shown in Table 14.10 inoperable, the inoperable component must be restored within 30 days when the unit is in modes 1, 2, or 3.
Table 14.10 defines the Fire Safe Shutdown (FSSD) condition as OPERABLE for the Temperature Control Valves (TCV5) supplying for the Lower Compartment Coolers (LCCs) and Control Rod Drive Mechanism (CRDM) coolers. In Modes 1, 2, or 3, these valves are required to modulate to control temperature to their respective cooler.
OPERABLE for these TCVs is a position to ensure that their respective cooler has sufficient cooling flow to maintain the Reactor Building Lower Compartment temperature.
Functional Evaluations (FE5) have been performed on a single TCV, and determined that with the TCV in the open position it meets the requirement for FSSD condition.
B.14.10.2 With a breaker and/or valve specified in design output documents as being administratively controlled for Appendix R out of its required position (as noted on the drawing), the breaker and/or valve must be returned to the required position within 30 days when the unit is in Modes 1, 2, or 3. These breakers and/or valves are administratively controlled to prevent inadvertent operation during an Appendix R fire event. There is no TIR associated with the OR since the valves and/or breaker positions are controlled by the applicable System Operating Instruction and the plants configuration control program.
II - 110
PART II FIRE PROTECTION PLAN
- ev.2 B.14.1O.3 If the required action and associated completion time are not met, the plant must be placed in a condition where the OR does not apply. If possible, the inoperable or misconfigured component can be placed in the condition required for safe shutdown (i.e., close a valve, shutdown a pump, lock open a breaker), or a backup instrument can be provided for monitoring temperature, flow, or pressure. If this cannot be accomplished, an evaluation can be performed to justify using an alternate means to achieve compliance with Appendix R FSSD requirements. The plants Temporary Control and Alteration process (TACF) along with a 10CFR5O.59 review can also be used to provide the alternate means of FSSD compliance. If none of the above actions can be accomplished, the unit must be brought to at least Mode 3 within 6-hours and to Mode 4 within the following 12-hours.
II 111
PART II FIRE PROTECTION PLAN ev.22 BASES TESTING AND INSPECTION REQUIREMENTS (TIR)
FIRE SAFE SHUTDOWN EQUIPMENT B.14.10.a TIR 14.10.a is performance of a terminal voltage check and on alignment check of the plants 250 VDC Batteries I and 2. This provides assurance that the batteries are operable and aligned to the appropriate DC bus. This check will be performed at least once every 31 days when the plant is in modes 1, 2, or 3.
B.1 4.1 0.b TIR 14.1 0.b is performance of a breaker alignment check for the 250 VDC Battery Boards I and 2 and Distribution Panels 1 and 2. This check provides assurance that breakers which supply control power to steam load trip circuits and RCP breaker trip circuits are aligned properly. This check will be performed at least once every 31 days when the plant is in modes 1, 2, or 3.
B.14.10.c TIR 14.10.c verifies every 18 months that main steam system valves are capable of being closed via Main Control Room switch or locally by manual operation of the valve. This verifies that each valve operates properly to ensure the isolation of main steam loads should main steam isolation valves become inoperable in the event of a fire damage. The valves are tested every 18 months when the unit is shutdown since operation of the valve via the hand switch during operation can cause a reactor trip.
B.14.10.d TIR 14.10.d is performance of a channel calibration on instruments required for safe shutdown. Many of these instruments are required for local operation of plant systems and components during a fire event. The performance of the calibration ensures the accuracy of these instruments should they be required for use. This calibration is performed once per 18 months.
B.14.10.e TIR 14.10.e is performance of in-service testing for CCS pump 2B-B under the augmented in-service testing program. This pump is needed to support Unit 1 fire safe shutdown requirements. The augmented in-service testing program requires a flow verification at least once per 92 days to ensure that the pump is operable.
B.14.1 0.f TIR 14.1 0.f verifies every 92 days that RCS Pressurizer Spray Valves are capable of being closed from the Main Control Room controller. The valves are tested every 92 days (quarterly) in accordance with the augmented in-service testing program.
B.14.10.g TIR 14.10.g verifies every 18 months that the Control Rod Drive Cooler Motors and associated dampers operate properly from MCR controls. The CRDM Coolers and dampers are tested every 18 months when the unit is shutdown since these coolers are normally in operation during unit operation. Also, cycling these coolers on and off during plant operation could have an adverse effect on the Rod Position Indication System.
II 112
PART II FIRE PROTECTION PLAN RV.22 -
B.14.1O.h TIR 14.1O.h verifies every 18 months that the Generator Control System Solenoid can be operated from its associated hand switch in the MCR. This test is performed every 18 months when the unit is shutdown since operation of this solenoid will cause a unit trip. The solenoid is tested every 18 months as part of the Technical Requirements Surveillance Program.
B.14.1O.i TIR 14.1O.i verifies every 18 months that the Lower Compartment Cooler System Temperature Control Valves (TCV5) operate properly from MCR controls. The TCVs are tested every 18 months when the unit is shutdown since these coolers are required for Containment cooling during unit operation.
B.14.1O.j TIR 14.1O.j.a verifies every 31 days that the nitrogen tanks have the quantity and pressure of nitrogen required for operation of the valves. This check will be performed at least once every 31 days when the plant is in modes 1, 2 or 3.
TIR 14.1O.j.b verifies every 18 months that the SG PORVs and AFW LCVs can be operated properly from backup control stations using the compressed nitrogen. The PORV5 and LCV5 are tested every 18 months when the unit is shutdown since these valves are required to be operable per plant Technical Specifications when the plant is in operating modes 1 through 4 and testing these valves utilizing the nitrogen system would make the valves inoperable.
B.14.1O.k TIR 14.1O.k verifies every 92 days that the Auxiliary Control Air Compressors are capable of starting automatically if the air receiver pressure drops below a pre established setpoint. Re-establishing and maintaining system pressure ensure adequate capacity to meet the needs of the small set of components credited for remote pneumatic operation during Fire Safe Shutdown.
B.14.1O.l TIR-14.1O.l is for tracking only. The thermal overload bypass devices are tested by the Technical Requirements Manual and no further testing is needed. The concern for the FPR is for the overloads to be bypassed and thus defeating their protection features as addressed in the bases to OR-14.1O. This provides a method for the surveillance program to ensure OR-14.1O is entered should the associated tests not be performed and the overloads are bypassed.
B.14.1O.m TIR 14.1O.m verifies every 18 months that the CREATCS Appendix R transfer switches (O-XS-31-12-A and O-XS-31-11-B) function as intended by the performance of a continuity check. This will ensure that CREATCS is available for local control during an Appendix R fire that takes out the normal control circuit. The continuity test is consistent with the surveillance requirements for other safety related transfer switches (reference Technical Specification Bases SR3.3.4.2).

- Unit I is Mode 3 following a reactor trip on the previous shift.
- Auxiliary Air Compressor B is tagged for maintenance.
- A failed temperature switch results in an Auxiliary Building Isolation (ABI).
- ABGTS fan A-A trips due to motor failure when it attempts to starts.
In accordance with OPDP-8, Limiting Conditions for Operation Tracking, which ONE of the following identifies (1) how the ABGTS Train A entry will be designated in the OPDP-8, LCO Tracking Log and (2) if a Loss of Safety Function has occurred?
A Active LCO Has occurred B. Information Only LCO Has occurred C. Active LCO Has NOT occurred D. Information Only LCO Has NOT occurred Page 53
WBN 10-2011 NRC SRO Exam As Submitted 8115/2011 -
DIS TRACTOR ANAL YSIS:
A. Correct, The ABGTS is required in Mode 3, thus the fan failure resulting in Train A being inoperable would be entered in the LCO Tracking Log as an Active LCO and with the Train B auxiliary air compressor already out of service a Loss of Safety Function would exist because the qualified air supply to ABGTS Train B is not available. The auxiliary air is a support system for several systems, including ABGTS.
B. Incorrect, Plausible because Mode applicability changes as the plant enters different operating modes which result in Information Only entries into the Tech Spec Tracking Log and because a Loss of Safety Function occurring as a result of the ABGTS fan failure is correct since the Train B does not have its essential air supply auxiliary air compressor available.
C. Incorrect. Plausible because the ABGTS Train A failure being entered into the LCO Tracking Log as an Active LCO is correct and because there is control air available for the other Train of ABGTS.
D. Incorrect Plausible because Mode applicability changes as the plant enters different operating modes which result in Information Only entries into the Tech Spec Tracking Log and because there is control air available for the Train B of ABGTS from the plant control air system.
Question Number: 94 Tier: 3 Group N/A KIA: G2.1.18 Conduct of Operations Ability to make accurate, clear, and concise logs, records, status boards, and reports.
Importance Rating: 3.6 / 3.8 IOCFRPart55: 41.10/45.12/45.13 IOCFR55.43.b: 2 K/A Match: K/A is matched because the question requires knowledge of the LCO Tracking Log entry that is required to be made for the given mode and condition. The question is SRO because the SRO is responsible for completing the Tech Spec Tracking log and also for performing the Safety Function Determinations when SSC are made inoperable.

WBN Only 3.0 LOSS OF SAFETY FUNCTION DETERMINATION In accordance with TS 5.7.2.18, an LOSF exists when, assuming no concurrent single failure, a safety function assumed (explicitly or implicitly) in the accident analysis cannot be performed. An LOSF may exist when a support system is inoperable, and:
t
- A required system redundant to the system(s) supported by the inoperable suppor system is also inoperable; or
- A required system redundant to the system(s) in turn supported by the inoperable supported system is also inoperable; or
- A required system redundant to the support system(s) for the supported systems above is also inoperable.
3.1 Initiating an LOSF Evaluation A. Upon determining that an SSC is in a degraded or nonconforming condition and has been declared inoperable, an LOSF evaluation shall be initiated. Aflowchartof the process is depicted in FIGURE 1.
B. Determine if the inoperable SSC is directly addressed by a TS LCD. If the SSC is addressed in TS, then go to Step 3.ID, otherwise continue with Step C.
r C. If the inoperable SSC is not addressed in TS, then determine if it renders anothe SSC directly addressed in TS inoper able. If theinit ially inoper able SSC does not render a SSC addressed in TS inoper able, then no further action is require d, and no further LOSF evaluation is required.
D. Enter the applicable TS conditions and required actions for the inoperable TS SSCs determined in Steps 3.18 and/or 3.IC, above.
E. Determine if other inoperable SSCs exist for a TS LCD. If only one TS LCO action has been entered, then follow the required actions for that LCD, and no further LOSF evaluation is required. If more than one LCD is entered, then go to Step 3.1F.
F. Determine if the LCD whose required actions were entered is a support system. lf the inoperable SSC is a support system SSC, then continue to Step 3.1G. LCOs which are not support systems will generally not result in an LOSF when taken in combination with additional inoperabilities. Therefore, no further LOSF evaluation is required and the required actions of the applicable LCOs shall be met in accordance with LCD 3.0.2.
G. If more than one LCOs required actions were entered, then determine if all the LCOs have been entered for the same train or channel. If all LCOs were entered for the same train or channel, then no further LOSF evaluation is required. If more than one train or channel LCOs were entered, then continue to Step 3.1 H.

E. Verifier verifies the as-found configuration or condition matches the required position, without changing it, using one or more of the following means:
- 1. Hands-on verification that configuration is correct (e.g., manually checking valve position)
- 2. Observing remote indication
- 3. Observing correct system/equipment/component response F. Verifier confirms new configuration or condition agrees with guiding document and signs signature space provided in guiding document.
G. If as-found configuration or condition is incorrect, report the condition to supervision immediately.
3.3.3 Valves A. Valves that are to be verified open shall be manipulated in the closed direction only as necessary to remove any slack from the operating mechanism and verify valve stem movement. The valve shall then be fully opened, subject to normal precautions on backseating valves.
B. Valves that are to be verified closed shall be manipulated in the closed direction only as necessary to verify the valve is fully closed, and not binding or difficult to operate.
Care must be exercised, however, to avoid over torquing the valve operator and damaging the valve seat. If any doubt exists, SM should be contacted for resolution.
C. To determine the position of a throttled valve, the total number of turns until the handwheel stops moving in the open/closed direction shall be counted. To set the position of a throttled valve, open/close the valve the required number of turns from the full closed/open position (handwheel will no longer move in the closed/open direction).
D. Reach rod valve position indicators shall not be used as the sole method of position verification.
E. Locked valve and throttled valve position cannot be independently verified since these operations require the verifier to observe actions while they are being performed. CV shall be used to verify the position of locked and throttled valves in those cases where IV would normally be required.

Ill. Justification for Plant Specific Exemptions The 25 SRO-only questions shall evaluate the additional knowledge and abilities required for the higher license level in accordance with 10 CFR 55.43(b). [NUREG 1021, Section ES-401D.2.dj The fact that a facility licensee trains its ROs to master certain 10 CFR 55.43 knowledge, skills, and abilities does NOT mean that they can no longer be used as a basis for SRO-only questions. [Operator Licensing Feedback Web page Item 401.36 @ http://www.nrc.ciov/reactors/operator-Iicensinci/op-IicensinQ-files/ol-feedback. pdfl The SRO-only test item is required to be tied to one of the 10 CFR 55.43(b) items. However, if a licensee desires to evaluate a knowledge/ability that is not tied to one of the 10 CFR 55.43(b) items, then the licensee can classify the knowledge/ability as unique to the SRO position provided that there is documented evidence that ties the knowledge/ability to the licensees SRO job position duties in accordance with the systematic approach to training (SAT).
> Justification: A question that is not tied to one of the 10 CFR 55.43(b) items can still be classified as SRO-only provided the licensee has documented evidence to prove that the knowledge/ability is unique to the SRO position at the site. An example of documented evidence includes:
o The question is linked to a learning objective that is specifically labeled in the lesson plan as being SRO-only (e.g., some licensee lesson plans have columns in the margin that differentiate AO, RO, and SRO learning objectives) [NUREG 1021, ES-401, Section D.2.d]
AND/OR o A question is linked to a task that is labeled as an SRO-only task, and the task is NOT listed in the RO task list.

1.0 INTRODUCTION
1.1 Purpose A. This Surveillance Instruction (SI) provides detailed steps to verify that the drop time of each shutdown and control rod from the fully withdrawn position is 2.7 seconds from the beginning of decay of stationary gripper voltage to dash pot entry. The SI is performed after each removal of the reactor head before returning the reactor to criticality with:
- 1. Tavg551°F.
- 2. All reactor coolant pumps operating.
B. Measuring the rod drop times before reactor criticality, after reactor vessel head removal, ensures that the reactor internals and rod drive mechanisms do NOT interfere with rod motion or adversely impact the drop times during operation in Modes 1 and 2.
1.2 Scope Rod drop times for shutdown and control rods are measured by withdrawing all shutdown and control rod banks to the fully withdrawn position (i.e., 231 steps), and then tripping the reactor to simultaneously measure the drop times for all rods using the Rod Drop Test Computer (RDTC) in l-R-44. The RDTC receives an input from two steam dump relays which are operated by interposing relays operated by the opening of the reactor trip breakers. Either of the relays provides a start signal to measure the rod drop times. The RDTC then measures the induced voltage on the Rod Position Indication (RPI) detector secondary coils by the motion of the falling Control Rod Drive Mechanism (CRDM) drive shaft.
This SI conservatively defines rod drop time as being the time from when the Reactor Trip Breakers change status (i.e. the breakers open following a reactor trip) until dashpot entry occurs. The CERPI Rod Drop Test Computer (RDTC) relies on a contact change of state for a starting time. The contact change of state occurs slightly after the Reactor Trip Breakers open (<100 msec)(Reference 2.2.D).
Therefore, acceptance criteria in this SI is different from acceptance criteria in 1 -SI-85-1 which uses the actual Reactor Trip Breakers opening as a start signal.
I .2.1 Operability Tests To be Performed This SI demonstrates rod freedom of movement (i.e., tripability) by withdrawing all shutdown and control banks, tripping the reactor, and simultaneously measuring the drop time for all rods to verify that the drop times are within the bounds (i.e., less than or equal to the drop times) of the cycle specific transient safety analysis assumptions.

F. Procedures and limitations involved in initial core loading, alterations in core configuration, control rod programming, and determination of various internal and external effects on core reactivity. [10 CFR 55.43(b)(6)]
Some examples of SRO exam items for this topic include:
o Evaluating core conditions and emergency classifications based on core conditions.
o Administrative requirements associated with low power physics testing processes.
- Administrative requirements associated with refueling activities, such as approvals required to amend core loading sheets or administrative controls of potential dilution paths and/or activities.
- Administrative controls associated with the installation of neutron sources.
- Knowledge of TS bases for reactivity controls.
G. Fuel handling facilities and procedures. [10 CFR 55.43(b)(7)j Some examples of SRO exam items for this topic include:
- Refuel floor SRO responsibilities.
- Assessment of fuel handling equipment surveillance requirement acceptance criteria.
- Prerequisites for vessel disassembly and reassembly.
- Decay heat assessment.
- Assessment of surveillance requirements for the refueling mode.
- Reporting requirements.
Emergency classifications.
This does not include items that the RD may be responsible for at some sites such as fuel handling equipment and refueling related control room instrumentation operability requirements, abnormal operating procedure immediate actions, etc. For example, an RD is required to stop the refueling process when communication is lost between the control room and the refueling floor, therefore, this is a task that is both an RD and SRO responsibility and is not SRO-only.

- Unit 1 reactor is critical below the Point of Adding Heat in accordance with GO-2, Reactor Startup, during startup following a refueling outage.
- Physics Testing has been declared, and PET-201, Initial Criticality and Low Power Physics Testing, is in progress.
- The Plant Manager assigned a senior line manager (CIPTE Manager) to exercise continuous responsibility for the oversight of PET-201.
- Isothermal Temperature Coefficient Measurement is being performed.
In accordance with NPG-SPP-06.9.1, Conduct of Testing, which ONE of the following identifies...
(1) how the Shift Managers responsibility for conduct of the test is affected by having a CIPTE Manager assigned and (2) who is responsible for conducting the CIPTE PRE-TEST BRIEFING CHECKLIST on management expectations for the test?
A. (1) The Shift Manager retains the responsibility for the control of the performance of PET-201.
(2) Test Director Bb (1) The Shift Manager retains the responsibility for the control of the performance of PET-201.
(2) Plant Managers designee C. (1) The CIPTE Manager assumes the responsibility for the control of PET-201 from the Shift Manager.
(2) Test Director D. (1) The CIPTE Manager assumes the responsibility for the control of PET-201 from the Shift Manager.
(2) Plant Managers designee Page 62
WBN 10-2011 NRC SRO Exam As Submitted 811512011 DISTRA CTOR ANAL YSIS:
A. Incorrect, Plausible because the Shift Manager retaining the responsibility for controlling the performance is correct and the Test Director is responsible for conducting the briefings required by the SPP for the test except for the Management Expectations Briefing.
B. Correc1, PET 201 is a CIPTE (Complex or Infrequently Performed Test or Evolution) and NPG-SPP-06. 9.1, Conduct of Testing, requires the Plant Manager or designee to determine the need to assign a Senior Manager to provide continuous oversight of the test. However, the Shift Manager retains the responsibility for the control of the test. The SPP identifies that the assigned manager does not reduce the Shift Managers authority/responsibility. Briefing requirements change when a procedure is a CIPTE. The Plant Manager or his designee is required to conduct the Management Expectation Briefings Checklist using the Table in the SPP.
C. IncorrecI, Plausible because the manager assigned as the CIPTE manager does have responsibility for controlling the pace of the test and the resolution (or escalation) of problems encountered during the test and the Test Director is responsible for conducting the briefings required by the SPP for the test except for the Management Expectations Briefing.
D. lncorrect Plausible because the manager assigned as the CIPTE manager does have responsibility for controlling the pace of the test and the resolution (or escalation) of problems encountered during the test and the Plant Manager or designee is responsible for conducting the briefings the Management Expectations Briefing.
3.8 Complex Infrequently Performed Tests or Evolutions E. For CIPTEs, the test director will conduct pre-test formal briefings as required [i.e., one before the test crew assumes shift duties (a general test overview), usually at the Operations Shift Turnover Meeting, and a second before commencing the test (a detailed briefing)].
F. At the Test Directors pre-test formal briefing, the Plant Manager or designee for the test shall conduct a briefing for Operations and testing personnel on management expectations for the test utilizing Form NPG-SPP-06.9.1-3.
G. The Plant Manager or his designee shall determine the need to designate a senior line manager to advise the Shift Manager or Unit Supervisor, who has the authority and experience to exercise continuous responsibility for the oversight of a particular test or evolution. This authority includes control of the pace of the CIPTE and the resolution (or escalation) of problems encountered.
NOTE This is an oversight position and shall not interfere with or reduce the Shift Managers responsibility for control of the test.
H. For CIPTEs, the test director will conduct a post test briefing, as required by CIPTE Manager, to discuss lessons learned to include as a minimum potential procedure changes and training.

F. Procedures and limitations involved in initial core loadinci, alterations in core configuration, control rod grogramming, and determination of various internal and external effects on core reactivity. [10 CFR 55.43(b)(6)]
Some examples of SRO exam items for this topic include:
- Evaluating core conditions and emergency classifications based on core conditions.
- Administrative requirements associated with low power physics testing processes.
- Administrative requirements associated with refueling activities, such as approvals required to amend core loading sheets or administrative controls of potential dilution paths and/or activities.
- Administrative controls associated with the installation of neutron sources.
- Knowledge of TS bases for reactivity controls.
G. Fuel handling facilities and grocedures. [10 CFR 55.43(b)(7)]
Some examples of SRO exam items for this topic include:
- Refuel floor SRO responsibilities.
- Assessment of fuel handling equipment surveillance requirement acceptance criteria.
- Prerequisites for vessel disassembly and reassembly.
- Decay heat assessment.
- Assessment of surveillance requirements for the refueling mode.
- Reporting requirements.
- Emergency classifications.
This does not include items that the RD may be responsible for at some sites such as fuel handling equipment and refueling related control room instrumentation operability requirements, abnormal operating procedure immediate actions, etc. For example, an RD is required to stop the refueling process when communication is lost between the control room and the refueling floor, therefore, this is a task that is both an RD and SRO responsibility and is not SRO-only.

WBN 10-2011 NRC SRO Exam As Submitted 8/15/2011 DISTRACTOR ANAL YSIS:
A. Incorrect, reducing Tavg below 350°F is not correct but the basis is being to limit doses in the event of a SGTR is correct. Plausible because lowering Tavg to 350°F would allow RHR to be placed in service and discontinue the use of the SGs as the heat sink and because a LOCA with leakage from containment could cause elevated doses at the site boundary. The distractor for a LOCA in conjunction with 0.25%/day leakage from containment is from wording in the Bases for Tech Spec 3.6.1, Containment, and 3.6.2, Containment Air Locks.
B. Incorrect, reducing Tavg below 500°F is correct but the bases is not due to a LOCA with assumed containment leakage. Plausible because the action stated is correct and a LOCA with leakage from containment could cause elevated doses at the site boundary. The distractor for a LOCA in conjunction with 0.25%/day leakage from containment is from wording in the Bases for Tech Spec 3.6.1, Containment, and 3.6.2, Containment Air Locks.
C. Incorrect, reducing Tavg below 350°F is not correct and the basis is not due to a LOCA with assumed containment leakage. Plausible because lowering Tavg to 350°F would allow RHR to be placed in service and discontinue the use of the SGs as the heat sink and because the basis being to limit the dose rate at the site boundary is correct.
D. Correct, with the activity above the 0.265 microcuries/gram limit in the Tech Spec 3.4.16 for 48 continuous hours, Tavg is required to be reduced to less than 500°F within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> in accordance with the Tech Spec. The T/S bases indicate that reducing Tavg below 500°F prevents the release of activity should a steam line break occur since the saturation pressure of the primary coolant is below the lift pressure of the atmospheric steam relief valves. The limit on activity is based on the resulting 2-hour doses at the site boundary not exceeding a small fraction of the 10 CFR 100 limits following a SGTR or a Main Steam Line Break in conjunction with an assumed steady state SG tube leak oflSO gpd.

B 3.4.16 RCS Specific Activity BASES BACKGROUNDThe maximum dose to the whole body and the thyroid that an individual at the site boundary can receive for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> during an accident is specified in 10 CFR 100 (Ref. 1). The maximum dose to the whole body and the thyroid that an individual occupying the Main Control Room can receive for the accident duration is specified in 10 CFR 50, Appendix A, GDC 19. The limits on specific activity ensure that the doses are held to a small fraction of the 10 CFR 100 limits and within the 10 CFR 50, Appendix A, GDC 19 limits during analyzed transients and accidents.
The RCS specific activity LCO limits the allowable concentration level of radionuclides in the reactor coolant. The LCO limits are established to minimize the offsite and Main Control Room radioactivity dose consequences in the event.
of a steam generator tube rupture (SGTR) or main steam line break (MSLB) accident.
The LCO contains specific activity limits for both DOSE EQUIVALENT 131 and gross specific activity. The allowable levels are intended to limit the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> dose at the site boundary to a small fraction of the 10 CFR 100 dose guideline limits, and ensure the Main Control Room accident dose is within the appropriate 10 CFR 50, Appendix A, GDC 19 dose guideline limits.
The evaluations showed the potential offsite and Main Control Room dose levels for a SGTR and MSLB accident were within the appropriate 10 CFR 100 and GDC 19 guideline limits.
APPLICABLE The LCO limits on the specific activity of the reactor coolant ensures that the SAFETY ANALYSES resulting 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> doses at the site boundary and Main Control Room accident doses will not exceed the appropriate 10 CFR 100 dose guideline limits and 10 CFR 50, Appendix A, GDC 19 dose guideline limits following a SGTR or MSLB accident. The SGTR and MSLB safety analysis (Ref. 2) assume the specific activity of the reactor coolant at the LCO limit and an existing reactor coolant steam generator (SG) tube leakage rate of 150 gallons per day (GPD). The safety analysis assumes the specific activity of the secondary coolant at its limit of 0.1 pCi/gm DOSE EQUIVALENT 1-131 from LCO 3.7.14, Secondary Specific Activity.
(continued)
Watts Bar-Unit I B 3.4-93 Revision 52 Amendment 41
RCS SpecEfic ActMty B 3.4.16 BASES APPLICABLE The analysis for the SGTR and MSLB accidents establish the acceptance limits SAFETY ANALYSES for RCS specific activity. Reference to these analyses is used to assess (continued) changes to the unit that could affect RCS specific activity, as they relate to the acceptance limits.
The analyses are for two cases of reactor coolant specific activity. One case assumes specific activity at 0.265 iCi/gm DOSE EQUIVALENT 1-131 with an iodine spike immediately after the accident that increases the iodine activity in the reactor coolant by a factor of 500 times the iodine production rate necessary to maintain a steady state iodine concentration of 0.265 1 iCi/gm DOSE EQUIVALENT 1-131. The second case assumes the initial reactor coolant iodine activity at 21 iCi/gm DOSE EQUIVALENT 1-131 due to a pre-accident iodine spike caused by an RCS transient. In both cases, the noble gas activity in the reactor coolant equals the LCO limit of 100/ E pCi/gm for gross specific activity.
The analysis also assumes a loss of offsite power at the same time as the SGTR and MSLB event. The SGTR causes a reduction in reactor coolant inventory.
The reduction initiates a reactor trip from a low pressurizer pressure signal or an RCS overtemperature zT signal. The MSLB results in a reactor trip due to low steam pressure.
The coincident loss of offsite power causes the steam dump valves to close to protect the condenser. The rise in pressure in the ruptured SG discharges radioactively contaminated steam to the atmosphere through the SG power operated relief valves and the main steam safety valves. The unaffected SGs remove core decay heat by venting steam to the atmosphere until the cooldown ends.
The safety analysis shows the radiological consequences of a SGTR and MSLB accident are within the appropriate 10 CFR 100 and 10 CFR 50, Appendix A, GDC 19 dose guideline limits. Operation with iodine specific activity levels greater than the LCO limit is permissible, if the activity levels do not exceed 21 pCi/gm DOSE EQUIVALENT 1-131, in the applicable specification, for more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The safety analysis has concurrent and pre-accident iodine spiking levels up to 21 pCi/gm DOSE EQUIVALENT 1-131.

LCO The specific iodine activity is limited to 0.265 iCi/gm DOSE EQUIVALENT 1-131, and the gross specific activity in the reactor coolant is limited to the number of iCi/gm equal to 100 divided by E (average disintegration energy of the sum of the average beta and gamma energies of the coolant nuclides). The limit on DOSE EQUIVALENT 1-131 ensures the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> thyroid dose to an individual at the site boundary and accident dose to personnel in the Main Control Room during the Design Basis Accident (DBA) will be within the allowed thyroid dose.
The limit on gross specific activity ensures the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> whole body dose to an individual at the site boundary and accident dose to personnel in the Main Control Room during the DBA will be within the allowed whole body dose.
The SGTR and MSLB accident analysis (Ref. 2) shows that the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> site boundary dose levels and Main Control Room accident dose are within acceptable limits. Violation of the LCO may result in reactor coolant radioactivity levels that could, in the event of a SGTR or MSLB, lead to site boundary doses that exceed the 10 CFR 100 dose guideline limits, or Main Control Room accident dose that exceed the 10 CFR 50, Appendix A, GDC 19 dose limits.
APPLICABILITY In MODES I and 2, and in MODE 3 with RCS average temperature 500°F, operation within the LCO limits for DOSE EQUIVALENT 1-131 and gross specific activity are necessary to contain the potential consequences of an accident to within the acceptable Main Control Room and site boundary dose values.
For operation in MODE 3 with RCS average temperature < 500°F, and in MODES 4 and 5, the release of radioactivity in the event of a SGTR is unlikely since the saturation pressure of the reactor coolant is below the lift pressure settings of the main steam safety valves.

The Completion Time of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is required, if the limit violation resulted from normal iodine spiking.
A Note permits the use of the provisions of LCO 3.0.4.c. This allowance permits entry into the applicable MODE(S) while relying on the ACTIONS. This allowance is acceptable due to the significant conservatism incorporated into the specific activity limit, the low probability of an event which is limiting due to exceeding this limit, and the ability to restore transient specific activity excursions while the plant remains at, or proceeds to power operation.
B.1 and B.2 With the gross specific activity in excess of the allowed limit, an analysis must be performed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to determine DOSE EQUIVALENT 1-131.

SURVEILLANCE SR 3.4.16.1 REQUIREMENTS SR 3.4.16.1 requires performing a gamma isotopic analysis as a measure of the gross specific activity of the reactor coolant at least once every 7 days. While basically a quantitative measure of radionuclides with half lives longer than 15 minutes, excluding iodines, this measurement is the sum of the degassed gamma activities and the gaseous gamma activities in the sample taken. This Surveillance provides an indication of any increase in gross specific activity.
Trending the results of this Surveillance allows proper remedial action to be taken before reaching the LCO limit under normal operating conditions. The Surveillance is applicable in MODES 1 and 2, and in MODE 3 with Tavg at least 500°F. The 7 day Frequency considers the unlikelihood of a gross fuel failure during the time.
SR 3.4.16.2 This Surveillance is performed in MODE I only to ensure iodine remains within limit during normal operation and following rapid power changes when fuel failure is more apt to occur. The 14 day Frequency is adequate to trend changes in the iodine activity level, considering gross activity is monitored every 7 days. The Frequency, between 2 and 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after a power change 15% RTP within a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period, is established because the iodine levels peak during this time following fuel failure; samples at other times would provide inaccurate results.

RCS Specific Acttvtty B 3.4.16 BASES SURVEILLANCE SR 3.4.16.3 REQUIREMENTS (continued) A radiochemical analysis for E determination is required every 184 days (6 months) with the plant operating in MODE 1 equilibrium conditions. The E determination directly relates to the LCO and is required to verify plant operation within the specified gross activity LCO limit. The analysis for E is a measurement of the average energies per disintegration for isotopes with half lives longer than 15 minutes, excluding iodines. The Frequency of 184 days recognizes E does not change rapidly.
This SR has been modified by a Note that indicates sampling is required to be performed within 31 days after a minimum of 2 effective full power days and 20 days of MODE 1 operation have elapsed since the reactor was last subcritical for at least 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Lhis ensures that the radioactive materials are at equilibrium so the analysis for E is representative and not skewed by a crud burst or other similar abnormal event.

Containment B 3.6.1 BASES BACKGROUND a. All penetrations required to be closed during accident (continued) conditions are either:
- 1. capable of being closed by an OPERABLE automatic containment isolation system, or
- 2. closed by manual valves, blind flanges, or de-activated automatic valves secured in their closed positions, except as provided in LCO 3.6.3, Containment Isolation Valves.
- c. All equipment hatches are closed.
APPLICABLE The safety design basis for the containment is that the containment must SAFETY ANALYSES withstand the pressures and temperatures of the limiting DBA without exceeding the design leakage rates.
The DBAs that result in a challenge to containment OPERABILITY from high pressures and temperatures are a loss of coolant accident (LOCA), a steam line break (SLB), and a rod ejection accident (REA) (Ref. 2). In addition, release of significant fission product radioactivity within containment can occur from a LOCA or REA. In the DBA analyses, it is assumed that the containment is OPERABLE such that, for the DBAs involving release of fission product radioactivity, release to the environment is controlled by the rate of containment leakage. The containment was designed with an allowable leakage rate of 0.25% of containment air weight per day (Ref. 3). This leakage rate, used in the evaluation of ofisite doses resulting from accidents, is defined in 10 CFR 50, Appendix J, Option B (Ref. 1), as La: the maximum allowable containment 10 leakage rate at the calculated peak containment internal pressure (Pa) related to
( the design basis LOCA. The allowable leakage rate represented by La forms the basis for the acceptance criteria imposed on all containment leakage rate testing.
jJ La is assumed to be 0.25% per day in the safety analysis at Pa = 15.0 psig which bounds the calculated peak containment internal pressure resulting from the limiting design basis LOCA (Ref. 3).

Containment Air Locks B 3.6.2 BASES (continued)
APPLICABLE The DBAs that result in a significant release of radioactive material within SAFETY containment are a loss of coolant accident and a rod ejection accident ANALYSES (Ref. 2). In the analysis of each of these accidents, it is assumed that containment is OPERABLE such that release of fission products to the environment is controlled by the rate of containment leakage. The containment was designed with an allowable leakage rate (La)Of 0.25% of containment air N weight per day (Ref. 2), at the calculated peak containment pressure of 15.0
\A psig. This allowable leakage rate forms the basis for the acceptance criteria imposed on the SRs associated with the air locks.
The containment air locks satisfy Criterion 3 of the NRC Policy Statement.
LCO Each containment air lock forms part of the containment pressure boundary. As part of containment pressure boundary, the air lock safety function is related to control of the containment leakage rate resulting from a DBA. Thus, each air locks structural integrity and leak tightness are essential to the successful mitigation of such an event.
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE.
Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into and exit from containment.

Clarification- Guidance for SRO-only Questions Rev 1 (03111/2010)
F. Procedures and limitations involved in initial core loading, alterations in core configuration, control rod rrogramming, and determination of various internal and external effects on core reactivity. [10 CFR 5543(b)(6)]
Some examples of SRO exam items for this topic include:
- Evaluating core conditions and emergency classifications based on core conditions.
- Administrative requirements associated with low power physics testing processes.
- Administrative requirements associated with refueling activities, such as approvals required to amend core loading sheets or administrative controls of potential dilution paths and/or activities.
- Administrative controls associated with the installation of neutron sources.
- Knowledge of TS bases for reactivity controls.
G. Fuel handling facilities and procedures. [10 CFR 55.43(b)(7)j Some examples of SRO exam items for this topic include:
- Refuel floor SRO responsibilities.
- Assessment of fuel handling equipment surveillance requirement acceptance criteria.
- Prerequisites for vessel disassembly and reassembly.
- Decay heat assessment.
- Assessment of surveillance requirements for the refueling mode.
- Reporting requirements.
- Emergency classifications.
This does not include items that the RO may be responsible for at some sites such as fuel handling equipment and refueling related control room instrumentation operability requirements, abnormal operating procedure immediate actions, etc. For example, an RO is required to stop the refueling process when communication is lost between the control room and the refueling floor, therefore, this is a task that is both an RO and SRO responsibility and is not SRO-only.

Clarification Guidance for SROonly Questions Rev 1(0311112010)
Ill. Justification for Plant Specific Exemptions The 25 SRO-only questions shall evaluate the additional knowledge and abilities required for the higher license level in accordance with 10 CFR 55.43(b). [NUREG 1021, Section ES-401 D.2.d]
The fact that a facility licensee trains its ROs to master certain 10 CFR 55.43 knowledge, skills, and abilities does NOT mean that they can no longer be used as a basis for SRO-only questions. [Operator Licensing Feedback Web page Item 401.36 © http://www.nrc.Qov/reactors/operator-Iicensincl/op-jicensinci-files/ol-feedback. df]
The SRO-only test item is required to be tied to one of the 10 CFR 55.43(b) items. However, if a licensee desires to evaluate a knowledge/ability that is not tied to one of the 10 CFR 55.43(b) items, then the licensee can classify the knowledge/ability as unique to the SRO position provided that there is documented evidence that ties the knowledge/ability to the licensees SRO job position duties in accordance with the systematic approach to training (SAT).
> Justification: A question that is not tied to one of the 10 CFR 55.43(b) items can still be classified as SRO-only provided the licensee has documented evidence to prove that the knowledge/ability is unique to the SRO position at the site. An example of documented evidence includes:
o The question is linked to a learning objective that is specifically labeled in the lesson plan as being SRO-only (e.g., some licensee lesson plans have columns in the margin that differentiate AO, RO, and SRO learning objectives) [NUREG 1021, ES-401, Section D.2.d]
AND/OR o A question is linked to a task that is labeled as an SRO-only task, and the task is NOT listed in the RO task list.
