However, doing so would be inconsistent with the basis of Completion Therefore, there shall administrative controls to limit the maximum time allowed combination of Conditions that result in a single contiguous occurrence of failing to LCO.

administrative controls ensure that Completion Times for Conditions are not inappropriately extended."

A second Completion Time is included for certain Conditions/Required Actions to establish a limit on the maximum time allowed for any combination of Conditions that result in a contiguous failure to meet the Limiting Condition for Operation (LCO).

These second Completion Times are joined to the Condition Completion discovery of meet the The second Completion Times associated with 3.6.6 RAs A.1 and 1,

Therefore, this change is considered administrative.

Regulatory Evaluation:

4.1. Significant hazards Consideration SNC has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The change proposed by incorporating TSTF-439-A, Revision 2, eliminates certain Completion Times from the Technical Specifications. Completion Times are not an initiator to any accident previously evaluated. As a result, the probability of an accident previously evaluated is not affected. The consequences of an accident during the revised Completion Time are no different than the consequences of the same accident during the existing Completion Times. As a result, the consequences of an accident previously evaluated are not affected by this change. The proposed change does not alter or prevent the ability of structures, systems, and components (SSCs) from performing their intended function to mitigate the consequences of an initiating event within the assumed acceptance limits.

The proposed change described above does not affect the source term, containment isolation, or radiological release assumptions used in evaluating the radiological consequences of an accident previously evaluated. Further, the proposed change does not increase the types or amounts of radioactive effluent that may be released offsite, nor significantly increase individual or cumulative occupational/public radiation exposures. The proposed change is consistent with the safety analysis assumptions and resultant consequences. Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

Additionally, the proposed change to delete the note from TS Condition 3.6.6.A is administrative in nature and does not impact the operation, physical configuration, or function of plant structures systems, or components (SSCs). The proposed change does not impact the initiators or assumptions of analyzed events, nor does the proposed change impact the mitigation of accidents or E1-6

Basis transient events. Therefore, this proposed change not involve a significant in the probability or consequences of an accident previously evaluated.

proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

No.

proposed changes do not involve a physical alteration of the plant (Le. no new or different type of equipment will installed) or a change in the methods governing normal plant operation. The proposed changes do not any assumptions in the analysis. Therefore, the proposed changes not create possibility of a new or kind of accident from any previously the proposed involve a significant reduction in a margin of safety?

No.

proposed change to the second Completion Time does the manner in which safety limits, limiting system or limiting conditions for operation are The analysis are not change.

proposed change in plant operation in a configuration outside of basis. Therefore, the proposed does not involve a significant reduction in a of safety.

proposed change to the note from TS Condition 3.B.B.A is administrative in does not involve to plant SSCs, or manner in which f'\\nt:l.!"~'rQ" maintained, modified, or change a change to any

limits, system limiting conditions of operation, or parameters for any The proposed not impact any safety analysis assumptions and do not involve a change in initial conditions, system response times, or other affecting any analysis. The proposed change will not result in plant operation in a configuration of the basis. Therefore, proposed change significant reduction in a margin of safety.

l::Saf:;ea on above, SNC the proposed amendment involve a significant consideration the set forth in 10 and, accordingly, a finding of no significant hazards consideration is justified.

4.2. Applicable Regulatory Requirements/Criteria to NL-12-1002 Basis for Proposed Change 10 CFR 50.36, "Technical Specifications" - 10 CFR 50.36(c)(2) states, "When a limiting condition for operation of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the technical specifications until the condition can be met." The proposed change continues to meet the requirements of this regulation.

10 CFR 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants" - The overall objective of this performance-based rule is to ensure that nuclear power plant structures, systems, and components (SSCs) will be maintained so that they will perform their intended function when required.

4.3. Precedent TSTF-439-A, Revision 2 was approved for use as described in the following letter:

1. Letter from J. D. Hughey (U. S. Nuclear Regulatory Commission) to M. J. Pacilio (Exelon Nuclear), "Peach Bottom Atomic Power Station, Units 2 And 3 -Issuance Of Amendments Re: Adoption Of Technical Specification Task Force (TSTF) Traveler 439, Revision 2, 'Eliminate Second Completion Times Limiting Time From Discovery of Failure To Meet An LCO (Limiting Condition For Operation),' (TAC NOS. MD9449 AND MD9450)," dated July 30, 2010.

4.4. Conclusions Based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5.

Environmental Consideration SNC has evaluated the proposed amendment and has determined that the proposed amendment 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 off site, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment 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 amendment.

1.3 Completion Times 1.3 Completion Times DESCRIPTION (continued)

However, when a subsequent train, subsystem, component, or variable expressed in the Condition is discovered to be inoperable or not within limits, the Completion Time(s) may be extended. To apply this Completion Time extension, two criteria must first be met. The subsequent inoperability:

a.

Must exist concurrent with the first inoperability; and

b.

Must remain inoperable or not within limits after the first inoperability is resolved.

The total Completion Time allowed for completing a Required Action to address the subsequent inoperability shall be limited to the more restrictive of either:

a.

The stated Completion Time, as measured from the initial entry into the Condition, plus an additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; or

b.

The stated Completion Time as measured from discovery of the subsequent inoperability.

The above Completion Time extensions do not apply to those Specifications that have exceptions that allow completely separate re-entry into the Condition (for each train, subsystem, component, or variable expressed in the Condition) and separate tracking of Completion Times based on this re-entry. These exceptions are stated in individual Specifications.

The above Completion Time extension does not apply to a Completion Time with a modified "time zero." This modified "time zero" may be expressed as a repetitive time (i.e., "once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />," where the Completion Time is referenced from a previous completion of the Required Action versus the time of b the hrase "from discove (continued)

SR 3.6.6.1 Verifying the correct alignment for manual, power operated, and automatic valves in the containment spray flow path provides assurance that the proper flow paths will exist for Containment Spray System operation. This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since these were verified to be in the correct position prior to locking, sealing, or securing. This SR does not require any testing or valve manipulation. Rather, it involves verification that those valves outside containment (only check valves are inside containment) and capable of potentially being mispositioned are in the correct position.

A Note prohibits the application of LCO 3.0.4b to an inoperable AFW train. There is an increased risk associated with an AFW train inoperable and the provisions of LCO 3.0.4b, which allow entry into a MODE or other specified condition in the Applicability with the LCO not met after performance of a risk assessment addressing inoperable systems and components, should not be applied in this circumstance.

If one of the two steam supplies to the turbine driven AFW train is inoperable, action must be taken to restore OPERABLE status within 7 days. The 7 day Completion Time is reasonable, based on the following reasons:

a.

The redundant OPERABLE steam supply to the turbine driven AFW pump;

b.

The availability of redundant OPERABLE motor driven AFW pumps; and

c.

The low probability of an event occurring that requires the inoperable steam supply to the turbine driven AFW pump.

The seoond Completion Time for Required Action /\\.1 establishes a limit on the maximum time allowed for any combination of Conditions to be inoperable during any continuous failure to meet this LCO.

C.1 and C.2 When Required Action A.1 or B.1 cannot be completed within the required Cornpletion Time, or if two AFW trains are inoperable, the unit must be placed in a MODE in which the LCO does not apply. To achieve this status, the unit must be placed in at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems.

In MODE 4, AFW is not required since RHR is available.

If all three AFW trains are inoperable, the unit is in a seriously degraded condition with no safety related means for conducting a cooldown, and only limited means for conducting a cooldown with nonsafety related equipment. In such a condition, the unit should not be perturbed by any action, including a power change, that might result in a trip. The seriousness of this condition requires that action be started immediately to restore one AFW train to OPERABLE status.

This results in the requirement when in this Condition to traci{ the time elapsed from both the Condition A "time zero" and the "time zero" \\vhen LCO 3.8.1 was initially not met.

B.1 To ensure a highly reliable power source remains with an inoperable DG, it is necessary to verify the availability of the offsite circuits on a more frequent basis. Since the Required Action only specifies "perform," a failure of SR 3.8.1.1 acceptance criteria does not result in a Required Action being not met. However, if a circuit fails to pass SR 3.8.1.1, it is inoperable. Upon offsite circuit inoperability, additional Conditions and Required Actions must then be entered.

The 13.8/4.16 kV Standby Auxiliary Transformer (SAT) is a qualified offsite circuit that may be connected to the onsite Class 1 E distribution system independently of the RATs and may be utilized to meet the LCO 3.8.1 requirements for an offsite circuit. Its availability permits an extension of the allowable out-of-service time for a DG to 14 days from the discovery of failure to meet LCO 3.8.1. The SAT is available when it is:

II Operable in accordance with plant procedures; II Not already being applied to any of the four 4.16 kV ESF buses for Units 1 and 2 in accordance with Specification 3.8.1 as either an offsite source or to meet the requirements of an LCO 3.8.1 Condition; and, II Not providing power to the other unit when that unit is in MODE 5 or 6 or defueled.

Condition A worst scenario is one train without AC power (i.e., no offsite power to the train and the associated DG inoperable). In this Condition, the unit is more vulnerable to a complete loss of AC power.

The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> time limit before requiring a unit shutdown in this Condition is acceptable because of:

a.

The potential for decreased safety if the unit operator's attention is diverted from the evaluations and actions necessary to restore power to the affected train, to the actions associated with taking the unit to shutdown within this time limit; and

b.

The potential for an event in conjunction with a single failure of a redundant component in the train with AC power.

The stated Completion Time, as measured from the initial entry into the Condition, plus an additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; or

b.

The stated Completion Time as measured from discovery of the subsequent inoperability.

The above Completion Time extensions do not apply to those Specifications that have exceptions that allow completely separate re-entry into the Condition (for each train, subsystem, component, or variable expressed in the Condition) and separate tracking of Completion Times based on this re-entry. These exceptions are stated in individual Specifications.

The above Completion Time extension does not apply to a Completion Time with a modified "time zero." This modified "time zero" may be expressed as a repetitive time (i.e., "once per 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />," where the Completion Time is referenced from a previous completion of the Required Action versus the time of Condition entry) or as a time modified by the phrase "from discovery..."
