Vogtle Electric Generating Plant License Amendment Request for Adoption of TSTF-432-A, Revision 1, Change in Technical Specifications End States (WCAP-1 6294)
Enclosure 1 Basis for Proposed Changes to NL-14-1870 Basis for Proposed Changes Basis for Proposed Changes 1.0 Description Southern Nuclear Company, (SNC) requests an amendment to Operating Licenses for the Vogtle Electric Generating Plant (VEGP), Units 1 and 2, NPF-68 and NPF-81, respectively. The proposed change would modify the VEGP Technical Specifications to incorporate risk-informed requirements for selected Required Action end states. The changes are consistent with Technical Specification Task Force (TSTF) Standard Technical Specification (STS) Change Traveler TSTF-432-A Revision 1, "Change in Technical Specifications End States (WCAP-16294)." The availability of this TS improvement was announced in the Federal Register on May 11, 2012 (77 FR 27814) as part of the Consolidated Line Item Improvement Process (CLIIP).
2.0 Assessment 2.1 Applicability of Published Safety Evaluation SNC has reviewed Westinghouse Topical Report (TR) WCAP-16294 (Reference 1), the Nuclear Regulatory Commission (NRC) safety evaluation for WCAP-16294 (Reference 2), TSTF-432-A, Revision 1 (Reference 3), and the associated NRC model safety evaluation (Reference 4). SNC has concluded that the technical bases described in the Westinghouse topical report and TSTF-432-A, Revision 1, as well as the associated safety evaluation prepared by the NRC staff are applicable to VEGP Units 1 and 2 and support incorporation of this amendment request into the VEGP Unit 1 and 2 Technical Specifications.
The TSTF-432 justification references Regulatory Guide (RG) 1.182. On November 27, 2012, the NRC published a Federal Register Notice stating that RG 1.182 has been withdrawn and the subject matter has been incorporated into RG 1.160, "Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." RG 1.160 endorses NUMARC 93 01, Revision 4A, dated April 2011.
SNC assesses the risk of maintenance activities consistent with the guidance in RG 1.160. Therefore, the justification for adoption of TSTF-432 continues to be applicable.
2.2 Optional Changes and Variations SNC is proposing the following variations or deviations from the Westinghouse topical report, the TS changes described in the TSTF-432-A, Revision 1, or the NRC staff's model safety evaluation published in the Federal Register on May 11, 2012 (77 FR 27814) as part of the CLIIP Notice of Availability. In some instances, the Technical Specification number and or title may be different between the generic Improved Standard Technical Specifications (ISTS)
(Reference 5) on which TSTF-432-A was based and the VEGP Unit 1 and 2 specific TS; however, the justification for the proposed mode change remains directly applicable. Additionally, in some cases there may be content differences between the ISTS and VEGP TS due to plant specific or historical reasons.
Table 1 provides a comparison of the Technical Specifications action E1-1
Enclosure 1 to NL-14-1870 Basis for Proposed Changes requirements in TSTF-432-A and the corresponding VEGP Technical Specifications action requirements which are proposed for modification. These variations or deviations are discussed below:
- 1. ISTS TS 3.3.2, Engineered Safety Feature Actuation System Instrumentation, Condition K (VEGP TS 3.3.2, Condition K)
TS 3.3.2, Condition K applies to the Engineered Safety Feature Actuation System (ESFAS) Instrumentation safety feature for switchover from the refueling water storage tank (RWST) to the containment sump when RWST level is Low Low. The Completion Times for Required Actions K.1, K.2.1, and K.2.2 are bracketed values in the ISTS, and the values in the VEGP TS differ from those provided in TSTF-432-A, Revision 1.
TSTF-432-A, Revision 1, and ISTS TS 3.3.2, Required Action K.1 allow 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to place an inoperable RWST level Low Low channel in bypass, and Required Action K.2.1 states that the unit must be in Mode 3 within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (i.e., 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />) if Required Action K.1 is not completed within the specified time. As modified by TSTF-432-A, Revision 1, Required Action K.2.2 then allows an additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (i.e., 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />) to be in MODE 4.
As described in the Bases for VEGP TS 3.3.2, Condition K, the Completion Time for placing an inoperable RWST level Low-Low channel in bypass is 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, as justified in WCAP-14333-P-A, "Probabilistic Risk Analysis of the RPS and ESFAS Test Times and Completion Times," Revision 1. An additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (i.e., 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />) is provided to be in MODE 3 if Required Action K.1 is not completed. The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time for placing an inoperable RWST level Low-Low channel in bypass is retained, as is the requirement to be in MODE 3 within the next the 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (i.e., 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />) if Required Action K.lis not completed within the specified time. It is proposed that the Completion Time for Required Action K.2.2 be revised to allow an additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> (i.e., 84 hours9.722222e-4 days <br />0.0233 hours <br />1.388889e-4 weeks <br />3.1962e-5 months <br />) to be in MODE 4. Allowing 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to be in MODE 3, and additional 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> to be in MODE 4 when Required Action K.1 is not completed is consistent WCAP-1 6294, Revision 1, and TSTF-432-A, Revision 1.
.2. ISTS TS 3.3.7. Control Room Emerqency Filtration System Actuation Instrumentation, Condition C ISTS TS 3.3.7, Condition C provides end state requirements for inoperability of Control Room Emergency Filtration System Actuation Instrumentation. The VEGP TS do not include a corresponding specification for the Control Room Emergency Filtration System Actuation Instrumentation. The changes described in TSTF-432-A, Revision 1, for ISTS TS 3.3.7, Condition C are therefore not adopted.
- 3. ISTS TS 3.3.8, Fuel Buildinq Air Cleanup System Actuation Instrumentation, Condition D ISTS TS 3.3.8, Condition D provides end state requirements for inoperability of Fuel Building Air Cleanup System Actuation Instrumentation.
The VEGP TS do not include a corresponding specification for the Fuel Building Air Cleanup System Actuation Instrumentation. The changes E1-2 to NL-14-1870 Basis for Proposed Changes described in TSTF-432-A, Revision 1, for ISTS TS 3.3.8, Condition D are therefore not adopted.
- 4. ISTS TS 3.4.15, Reactor Coolant System Leakage Detection Instrumentation, Condition E (VEGP TS 3.4.15, Condition G)
VEGP TS 3.4.15 includes Conditions reflecting combinations of reactor coolant system leakage detection instrumentation inoperability that are not included in ISTS TS 3.4.15. The end state Completion Times for these additional Conditions are consistent with those evaluated in WCAP-16294, Revision 1, and provided in TSTF-432-A, Revision 1. The Completion Time for Required Action G.2 is revised to reflect these values.
- 5. ISTS TS 3.5.3, Emergency Core Cooling System - Shutdown, Conditions A, B, C (VEGP TS 3.5.3. Conditions A, B, C, D)
VEGP TS 3.5.3 includes an additional Condition (Condition B) for inoperability of an Emergency Core Cooling System (ECCS) centrifugal charging subsystem when 100% of the ECCS flow equivalent to a single ECCS train is available that is not included in ISTS TS 3.5.3. VEGP TS 3.5.3, Condition D is also modified from ISTS TS 3.5.3, Condition C to reflect the additional Condition. The additional and modified Conditions in VEGP TS 3.5.3 are plant-specific aspects of the licensing basis, and are not readily adaptable to the changes described in TSTF-432-A. Therefore, the TS and Bases changes identified in TSTF-432-A for ISTS 3.5.3 are not adopted.
VEGP TS 3.5.4 includes Conditions reflecting combinations of RWST sludge mixing equipment inoperability that are not included in ISTS TS 3.5.4. The end state Completion Times for these additional Conditions are consistent with those evaluated in WCAP-16294, Revision 1, and provided in TSTF-432-A, Revision 1. The Completion Time for Required Action E.2 is revised to reflect these values.
- 7. ISTS TS 3.6.6A, Containment Spray and Cooling Systems, Conditions B, E, and F VEGP does not utilize or credit chemical addition to the containment spray system for iodine removal. As such, ISTS TS 3.6.6B is the applicable ISTS TS for application of the changes in TSTF-432-A, Revision 1, and the changes identified for ISTS TS 3.6.6A are not adopted.
- 8. ISTS TS 3.6.6B, Containment Spray and Cooling Systems, Condition F (VEGP TS 3.6.6, Condition C)
ISTS TS 3.6.6B includes Conditions reflecting combinations of containment spray and cooling system inoperability that are not reflected in VEGP TS 3.6.6. For VEGP, since no end state path is provided for these inoperability combinations, their occurrence requires entry into LCO 3.0.3. The VEGP ECCS design is consistent with the design assumed in the ISTS and WCAP-1 6294, Revision 1. The end state Completion Times for those Conditions provided in VEGP TS 3.6.6 are consistent with those evaluated E1-3 to NL-14-1870 Basis for Proposed Changes in WCAP-1 6294, Revision 1, and provided in TSTF-432 A, Revision 1. The Completion Time for Required Action C.2 is revised to reflect these values.
- 9. ISTS TS 3.6.6C, Containment Spray System, Condition B The VEGP design does not include an ice condenser. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.6C are therefore not adopted.
- 10. ISTS TS 3.6.6D, Quench Spray System, Condition B The VEGP design does not include a Quench Spray System. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.6D are therefore not adopted.
- 11. ISTS TS 3.6.6E, Recirculation Spray System, Condition B The VEGP design does not include a Recirculation Spray System. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.6E are therefore not adopted.
Recirculation Fluid pH Control System, Condition B)
ISTS TS 3.6.7 provides Conditions for inoperability of the Spray Additive System. The VEGP design does not employ a Spray Additive System, and uses a recirculation fluid pH control system instead. The recirculation fluid pH control system consists of baskets of crystalline trisodium phosphate (TSP) that are located inside containment. The ISTS does not provide a model specification for recirculation fluid pH control systems that utilize TSP baskets, and it is therefore not specifically included in TSTF-432-A, Revision 1. However, end state Completion Times for recirculation fluid pH control systems that utilize TSP baskets are discussed in Section 3.1.15 of WCAP-16294, Revision 1. The Completion Time for Required Action B.2 of VEGP TS 3.5.6 is revised to reflect the value evaluated in WCAP-1 6294, Revision 1.
- 13. ISTS TS 3.6.11, Iodine Cleanup System, Condition B The VEGP design does not include an Iodine Cleanup System. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.11 are therefore not adopted.
- 14. ISTS TS 3.6.12, Vacuum Relief Valves, Condition B The VEGP design does not include containment vacuum relief valves. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.12 are therefore not adopted.
- 15. ISTS TS 3.6.13, Shield Building Air Cleanup System, Condition B The VEGP design does not include a shield building air cleanup system.
The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.13 are therefore not adopted El -4 to NL-14-1870 Basis for Proposed Changes
- 16. ISTS TS 3.6.14, Air Return System, Condition B The VEGP design does not include an ice condenser air return system.
The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.14 are therefore not adopted
- 17. ISTS TS 3.6.18, Containment Recirculation Drains, Condition C The VEGP design does not include containment recirculation drains. The changes identified in TSTF-432-A, Revision 1, for ISTS TS 3.6.18 are therefore not adopted
- 18. ISTS TS 3.7.9, Ultimate Heat Sink, Condition C (VEGP TS 3.7.9, Condition E)
VEGP TS 3.7.9 includes Conditions reflecting ultimate heat sink (UHS) equipment inoperabilities (i.e., fan/spray cell, basin transfer pump) that are not included in ISTS TS 3.7.9. Additionally, VEGP TS 3.7.9 does not include a Condition for UHS temperature that is included in ISTS TS 3.7.9.
The end state Completion Times for the additional Conditions reflect plant-specific attributes of the VEGP UHS design, and are consistent with those evaluated in WCAP-16294, Revision 1, and provided in TSTF-432-A, Revision 1. The omitted ISTS Condition for UHS temperature reflects plant specific attributes of the VEGP design and licensing basis does not alter this conclusion. The Completion Time for Required Action E.2 is revised to reflect these values.
- 19. ISTS TS 3.7.10, Control Room Emergency Filtration System, Condition C (VEGP TS 3.7.10, Control Room Emergency Filtration System - Both Units Operating., Condition F; VEGP TS 3.7.11, Control Room Emergqency Filtration System - One Unit Operating., Condition H)
The VEGP TS includes separate specifications for the Control Room Emergency Filtration System (CREFS) depending on whether both units are operating (TS 3.7.10), or one unit is operating (TS 3.7.11). The ISTS (and TSTF-432-A) provides a single specification that covers both operating conditions. VEGP TS 3.7.10 and 3.7.11 also include additional Completion Times reflecting combinations of CREFS equipment inoperability that are not reflected in ISTS TS 3.7.10. The Completion Times for these additional Conditions are consistent with those evaluated in WCAP-1 6294, Revision 1, and provided in TSTF-432-A, Revision 1. The end state Completion Times for VEGP TS 3.7.10, Required Action F.3, and VEGP TS 3.7.11, Required Action H.2, are revised to reflect these values.
- 20. ISTS TS 3.7.11, Control Room Emergency Air Temperature Control System, Condition B ISTS TS 3.7.11, Condition C provides end state requirements for inoperability of Control Room Emergency Air Temperature Control System.
The VEGP TS do not include a corresponding specification for the Control Room Emergency Air Temperature Control System. The changes described in TSTF-432-A, Revision 1, for ISTS TS 3.7.11, Condition B are therefore not adopted.
E1-5 to NL-14-1870 Basis for Proposed Changes
Condition C (VEGP TS 3.7.14, ESF Room Cooler and Safety-Related Chiller, Condition B)
ISTS TS 3.7.12 includes ECCS pump room exhaust cleanup and cooling equipment. The VEGP design does not include ECCS pump room exhaust cleanup equipment or depend on maintaining the ECCS pump rooms as a ventilation boundary. As a result, ISTS TS 3.7.12 includes Conditions for ECCS pump room filtration equipment inoperability and pump room boundary inoperability that are not included in VEGP TS 3.7.14.
ISTS 3.7.12 also includes the ECCS pump room coolers and chillers. The corresponding VEGP specification for this equipment is TS 3.7.14. ISTS TS 3.7.12 includes an additional Condition for two inoperable trains that does not appear in VEGP TS 3.7.14. The end state Completion Times for the Conditions in VEGP TS 3.7.14 are consistent with those evaluated in WCAP-1 6294, Revision 1, and provided in TSTF-432-A, Revision 1. The Completion Time for Required Action B.2 is revised to reflect these values.
- 22. ISTS TS 3.7.13, Fuel Building Air Cleanup System, Condition C ISTS TS 3.7.13, Condition C provides end state requirements for inoperability of the Fuel Building Air Cleanup System. The VEGP TS do not include a corresponding specification for the Fuel Building Air Cleanup System. The changes described in TSTF-432-A, Revision 1 for ISTS TS 3.7.13, Condition B are therefore not adopted.
- 23. ISTS TS 3.7.14, Penetration Room Exhaust Air Cleanup System, Condition C (VEGP TS 3.7.13, Piping Penetration Area Filtration and Exhaust System, Condition C)
ISTS TS 3.7.14, Condition C provides end state requirements for inoperability of the Penetration Room Exhaust Air Cleanup System. The corresponding VEGP requirements are located in TS 3.7.13, Piping Penetration Area Filtration and Exhaust System, Condition C.
- 24. ISTS TS 3.8.1. Alternating Current Sources - Operating, Condition G (VEGP TS 3.8.1, Condition H)
VEGP TS 3.8.1 includes an additional Condition that is not included in ISTS TS 3.8.1. This Condition is related to operability of the emergency diesel generators when the station auxiliary transformers are available, and reflects plant specific attributes of the VEGP design. The end state Completion Times for this additional Condition is consistent with those evaluated in WCAP-16294, Revision 1, and provided in TSTF-432-A, Revision 1. The Completion Time for Required Action H.2 is revised to reflect these values.
3.0 Regulatory Analysis 3.1 No Significant Hazards Consideration Southern Nuclear Corporation (SNC) has evaluated the proposed changes to the TS using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration.
E1-6 to NL-14-1870 Basis for Proposed Changes Description of Amendment Request: The proposed amendment would modify TS to risk-inform requirements regarding selected Required Action End States.
As required by 10 CFR 50.91 (a), the SNC analysis of the issue of no significant hazards consideration is presented below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the Limiting Conditions for Operation (LCO) is not restored. The requested Technical Specifications (TS) permit an end state of Mode 4 rather than an end state of Mode 5 contained in the current TS. In some cases, other Conditions and Required Actions are revised to implement the proposed change.
Required Actions are not an initiator of any accident previously evaluated. Therefore, the proposed change does not affect the probability of any accident previously evaluated. The affected systems continue to be required to be operable by the TS and the Completion Times specified in the TS to restore equipment to operable status or take other remedial Actions remain unchanged.
WCAP-16294-NP-A, Rev. 1, "Risk-Informed Evaluation of Changes to Tech Spec Required Action Endstates for Westinghouse NSSS PWRs," demonstrates that the proposed change does not significantly increase the consequences of any accident previously evaluated.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the LCO is not restored. In some cases, other Conditions and Required Actions are revised to implement the proposed change. The change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the change does not impose any new requirements. The change does not alter assumptions made in the safety analysis.
E1-7 to NL-14-1870 Basis for Proposed Changes Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No The proposed change modifies the end state (e.g., mode or other specified condition) which the Required Actions specify must be entered if compliance with the LCO is not restored. In some cases, other Conditions and Required Actions are revised to implement the proposed change. Remaining within the Applicability of the LCO is acceptable because WCAP-1 6294-NP-A demonstrates that the plant risk in MODE 4 is similar to or lower than MODE 5. As a result, no margin of safety is significantly affected.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
3.2 Applicable Regulatory Requirements/Criteria A description of the proposed TS change and its relationship to applicable regulatory requirements were published in the Model Safety Evaluation (SE)
(NRC ADAMS Accession Number ML120200384). SNC has reviewed the NRC staffs model SE referenced in the CLIIP Notice of Availability and concluded that the regulatory evaluation section is applicable to VEGP Unitsl and 2.
4.0 Environmental Considerations The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR Part 20, or would change an inspection or surveillance requirement.
However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

INSERT - BASES 3.3.2 Condition B Remaining within the Applicability of the LCO is acceptable to accomplish short duration repairs to restore inoperable equipment because the plant risk in MODE 4 is similar to or lower than MODE 5 (Ref. 18). In MODE 4 the Steam Generators and Residual Heat Removal System are available to remove decay heat, which provides diversity and defense in depth. As stated in Reference 18, the steam turbine driven Auxiliary Feedwater Pump must be available to remain in MODE 4. Should Steam Generator cooling be lost while relying on this Required Action, there are preplanned actions to ensure long-term decay heat removal. Voluntary entry into MODE 5 may be made as it is also acceptable from a risk perspective.
Required Action B.2.2 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 4. This Note prohibits the use of LCO 3.0.4.a to enter MODE 4 during startup with the LCO not met. However, there is no restriction on the use of LCO 3.0.4.b, if applicable, because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering MODE 4, and establishment of risk management actions, if appropriate.

K.1, K.2.1, and K.2.2 Condition K applies to:
- RWST Level - Low Low Coincident with Safety Injection.
This Condition contains bypass times and Completion Times that are risk-informed. The Configuration Risk Management Program (CRMP) is used to assess changes in core damage frequency resulting from applicable plant configurations. The CRMP uses the equipment out of service risk monitor, a computer based tool that may be used to aid in the risk assessment of on-line maintenance and to evaluate the change in risk from a component failure. The equipment out of service risk monitor uses the plant probabilistic risk assessment model to evaluate the risk of removing equipment from service based on current plant configuration and equipment condition.
RWST Level - Low Low Coincident With SI provides actuation of switchover to the containment sump. Note that this Function requires the bistables to energize to perform their required action.
The failure of up to two channels will not prevent the operation of this Function. However, placing a failed channel in the tripped condition could result in a premature switchover to the sump, prior to the injection of the minimum volume from the RWST. Placing the inoperable channel in bypass results in a two-out-of-three logic configuration, which satisfies the requirement to allow another failure without disabling actuation of the switchover when required.

REQUIREMENTS valves from being opened is set so the actual RCS pressure must be
< 450 psig to open the valves. This setpoint ensures the RHR design pressure will not be exceeded. To ensure that the RHR relief valves will not lift, the actual interlock setpoint used in performing the surveillance is < 365 psig, and takes into consideration various allowances for relief valve setting variation, transmitter elevation, and the total instrument channel uncertainty. The total instrument channel uncertainty is calculated in accordance with reference 9, and the allowance for process instrumentation (rack drift) is 1%. Once the interlock setpoint is initially reached, administrative controls ensure that the RHR suction isolation valves are closed prior to reaching an RCS pressure that could cause the RHR suction relief valves to open.
Due to the bistable reset design, the valves could be opened at a pressure above the interlock setpoint, but below the reset pressure.
The administrative controls ensure that the valves will not be opened if RCS pressure exceeds 365 psig after RCS pressure has decreased below the interlock setpoint.

RWST B 3.5.4 BASES ACTIONS B.1 and C.1 (continued)
The sludge mixing system isolation valves serve to isolate the non-safety grade mixing system from the RWST when the RWST level reaches the low level alarm. With this isolation capability inoperable, the potential exists for the inadvertent draining of the RWST below the required level via a failure (breach) in the sludge mixing system.
Therefore, action must be taken to restore the isolation valve(s) to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

This may be accomplished by closing the manual isolation valve(s) or deenergizing the OPERABLE solenoid pilot valve.
The times allowed for restoration or remedial action are reasonable considering the low probability of an event occurring during the specified time that would require the RWST, coincident with a sludge mixing system failure that would drain the RWST.
D.1 With the RWST inoperable for reasons other than Condition A or B (e.g., water volume), it must be restored to OPERABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
In this Condition, neither the ECCS nor the Containment Spray System can perform its design function. Therefore, prompt action must be taken to restore the tank to OPERABLE status or to place the plant in a MODE in which the RWST is not required.

SR 3.7.9.4 The verification of NSCW basin transfer pump operation includes testing to verify the pump's developed head at the flow test point is greater than or equal to the required developed head. Flow and differential head are normal tests of centrigual pump performance required by Section Xl of the ASME Code (Ref. 3).
This test confirms one point on the pumps design curve and is indicative of overall performance. Such inservice tests confirm component OPERABILITY, trend performance, and detect incipient failures by indicating abnormal performance. The performance of this surveillance in accordance with the Inservice Testing Program satisfies the requirements of Ref. 3.
SR 3.7.9.5 With one tower fan/spray cell out-of-service this SR verifies that ambient wet-bulb temperature remains within the three fan/spray cell region specified in Figure 3.7.9-1 so that the NSCW system remains capable of performing its design basis function.
Requiring this SR when forecasted temperature is > 48 0 F provides assurance that the ambient wet-bulb temperature specified in Figure 3.7.9-1 will not be exceeded while the fan is out-of-service. The 24-hour frequency is sufficient since the daily peak temperature is expected to occur once in a 24-hour interval.
Measurement of the ambient wet-bulb temperature should be made, near the time when the daily peak temperature is expected to occur, with a psychrometer in an open area away from sources of moisture, heat or wind, and within the owner-controlled area at Plant Vogtle.

1.1 ICondition H I Condition I corresponds to a level of degradation in which all redundancy in the AC electrical power supplies has been lost. At this severely degraded level, any further losses in the AC electrical power system will cause a loss of function. Therefore, no additional time is justified for continued operation. The unit is required by LCO 3.0.3 to commence a controlled shutdown.
SURVEILLANCE The AC sources are designed to permit inspection and testing REQUIREMENTS of all important areas and features, especially those that have a standby function, in accordance with 10 CFR 50, Appendix A, GDC 18 (Ref. 8). Periodic component tests are supplemented by extensive functional tests during refueling outages (under simulated accident conditions). The SRs for demonstrating the OPERABILITY of the DGs are in accordance with the recommendations of Regulatory Guide 1.9 (Ref. 3), Regulatory Guide 1.108 (Ref. 9), and Regulatory Guide 1.137 (Ref. 10), as addressed in the FSAR.

INSERT - BASES 3.8.1 Condition H Remaining within the Applicability of the LCO is acceptable to accomplish short duration repairs to restore inoperable equipment because the plant risk in MODE 4 is similar to or lower than MODE 5 (Ref. 14). In MODE 4 the Steam Generators and Residual Heat Removal System are available to remove decay heat, which provides diversity and defense in depth. As stated in Reference 14, the steam turbine driven Auxiliary Feedwater Pump must be available to remain in MODE 4. Should Steam Generator cooling be lost while relying on this Required Action, there are preplanned actions to ensure long-term decay heat removal. Voluntary entry into MODE 5 may be made as it is also acceptable from a risk perspective.
Required Action H.2 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 4. This Note prohibits the use of LCO 3.0.4.a to enter MODE 4 during startup with the LCO not met. However, there is no restriction on the use of LCO 3.0.4.b, if applicable, because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering MODE 4, and establishment of risk management actions, if appropriate. LCO 3.0.4 is not applicable to, and the Note does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

If one of the required DC electrical power sources is inoperable for reasons other than Condition A or B (e.g., inoperable battery charger or inoperable battery charger and associated inoperable battery), the remaining DC electrical power sources have the capacity to support a safe shutdown and to mitigate an accident condition. Since a subsequent worst case single failure could, however, result in the loss of the minimum necessary DC electrical sources to mitigate a worst case accident, continued power operation should not exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
