SUBJECT:

Fort Calhoun Station Unit No. 1 Revised License Amendment Request, "Application for Technical Specification Improvement Regarding Steam Generator Tube Integrity Using the Consolidated Line Item Improvement Process and Deletion of Sleeving as a Steam Generator Tube Repair Method" (TAC# MD2188)

Pursuant to 10 CFR 50.90, Omaha Public Power District (OPPD) hereby proposes to make changes to the Fort Calhoun Station Unit No. 1 (FCS) Technical Specifications (TS). The proposed amendment would revise the TS requirements related to steam generator tube integrity.

The change is consistent with NRC-approved Revision 4 to Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler TSTF-449, "Steam Generator Tube Integrity." The availability of this TS improvement was announced in the Federal Register on May 6, 2005 (70 FR 24126) as part of the consolidated line item improvement process (CLIIP).

OPPD also proposes to change the FCS TS by deleting the sleeving repair alternative to plugging for steam generator tubes. The FCS replacement steam generators (RSGs) to be installed during the fall of 2006 are manufactured by Mitsubishi Heavy Industries, Ltd. (MHI). The change is being requested because OPPD has determined that the sleeving repair alternative to plugging can not be used for the MHI RSGs at this time.

Reference 2 contained OPPD's original submittal with respect to TSTF-449. OPPD is resubmitting this amendment request to incorporate various revisions to the TS as a result of a Request for Additional Information (RAI) from the NRC staff. Attachment 5 provides the RAI questions and responses as discussed in a phone call on July 19, 2006. This revised amendment request does not change Attachment 1 as previously submitted, including the No Significant Hazards Consideration and the Environmental Evaluation.

U. S. Nuclear Regulatory Commission LIC-06-0087 Page 2 provides a description of the proposed change, the requested confirmation of applicability, and plant-specific verifications. Attachment 2 provides the existing TS pages marked up to show the proposed change. Attachment 3 provides revised (clean) TS pages. The proposed FCS TS changes are consistent with NRC approved Revision 4 of TSTF-449. Since FCS has custom TS, the numbering of the proposed TS and the location of information differ in some instances from TSTF-449. As a result, a cross reference table is provided in Attachment 4 to identify the location of TSTF-449 revisions in the FCS TS.

OPPD requests approval of the proposed amendment by November 1, 2006, to support scheduled implementation during the 2006 refueling outage. OPPD requests that the effective date for this TS change be the end of the 2006 refueling outage to allow for implementation of these proposed changes. No new commitments are made to the NRC in this letter.

I declare under penalty of perjury that the foregoing is true and correct. (Executed on August 30, 2006).

1.0 DESCRIPTION

The Omaha Public Power District (OPPD) proposes to revise the requirements in the Fort Calhoun Station Unit No. 1 (FCS) Technical Specifications (TS) related to steam generator tube integrity. The changes are consistent with NRC approved Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-449, "Steam Generator Tube Integrity," Revision 4. The availability of this technical specification improvement was announced in the Federal Register on May 6, 2005 as part of the consolidated line item improvement process (CLIIP). The proposed change also deletes steam generator tube sleeving as an alternative to plugging for steam generator tube repairs.

2.0 ASSESSMENT The proposed FCS TS changes are consistent with NRC approved Revision 4 of TSTF-449.

Since FCS has custom TS, however, the numbering of the proposed TS and the location of information differs in some instances from that of TSTF-449. Attachment 4 identifies the location of TSTF-449 revisions in the FCS TS.

Proposed revisions to the TS Bases are also included in this application. As discussed in the NRC's model safety evaluation, adoption of the revised TS Bases associated with TSTF-449, Revision 4 is an integral part of implementing this TS improvement. The changes to the affected TS Bases pages will be incorporated in accordance with the TS Bases Control Program.

3.0 BACKGROUND

The background for this application is adequately addressed by the NRC Notice of Availability published on May 6, 2005 (70 FR 24126), the NRC Notice for Comment published on March 2, 2005 (70 FR 10298), and TSTF-449, Revision 4.

The sleeving repair method for Combustion Engineering steam generators was added to the FCS TS by Amendment 195 (Reference 10.3). During the 2006 Refueling Outage, replacement steam generators (RSGs) will be installed at FCS. Because the RSGs are manufactured by Mitsubishi Heavy Industries, Ltd. (MHI), the RSG tubes do not have an approved sleeving repair alternative to plugging. Therefore, OPPD is requesting the deletion of the sleeving capability from the TS because analyses supporting the existing specification are not applicable to the MHI steam generators.

LIC-06-0087 Attachment I Page 3 4.0 REGULATORY REQUIREMENTS AND GUIDANCE The applicable regulatory requirements and guidance associated with this application are adequately addressed by the NRC Notice of Availability published on May 6, 2005 (70 FR 24126), the NRC Notice for Comment published on March 2, 2005 (70 FR 10298), and TSTF-449, Revision 4.

The proposed TS changes to delete surveillance requirements for a steam generator tube repair alternative (sleeving) are being requested since they will no longer be utilized or credited.

Likewise, the analyses supporting the tube sleeving repair alternative are not applicable and are not planned to be applied to the RSGs. Thus, the proposed changes eliminate requirements not applicable to the RSGs. The TS will still contain the steam generator tube surveillance requirements which existed before tube sleeving was incorporated by Amendment 195 (Reference 10.3). Other TS changes, not related to tube sleeving, made by Amendment 195 are not being affected or altered. In accordance with the FCS general design criteria (Reference 10.4), the FCS TS are being revised as a result of a change in facility equipment.

5.0 TECHNICAL ANALYSIS

OPPD has reviewed the safety evaluation (SE) published on March 2, 2005 (70 FR 10298) as part of the CLIIP Notice for Comment. This included the NRC staffs SE, the supporting information provided to support TSTF-449, and the changes associated with Revision 4 to TSTF-449. OPPD has concluded that the justifications presented in the TSTF proposal and the SE prepared by the NRC staff are applicable to FCS and justify this amendment for the incorporation of the changes to the FCS TS.

The proposed changes remove provisions added to the TS in Amendment 195 (Reference 10.3) related to the surveillance requirements of leak tight sleeves, and the reference to the Electric Power Research Institute (EPRI) Pressurized Water Reactor (PWR) Steam Generator Examination Guidelines in the basis. Other TS changes, not related to tube sleeving, implemented by Amendment 195 are not being affected or altered.

The proposed changes remove the capability for repairing degraded steam generator tubes using sleeving which was approved for the original Combustion Engineering steam generators. These generators are being replaced in the fall of 2006 with steam generators manufactured by MHI which are not expected to use the tube sleeving alternative to tube plugging. The proposed changes eliminate tube sleeving as a repair for the RSG tubes. These changes are necessary, not as a result of new or enhanced analyses or evaluations, but as a consequence of MHI's steam generator operating experience which has not resulted in the need to develop the sleeving repair option.

The proposed changes do not alter, degrade, or prevent actions described or assumed in any accident analysis. They will not change any assumptions previously made in evaluating

LIC-06-0087 Attachment 1 Page 4 radiological consequences or affect any fission product barriers, nor do they increase any challenges to safety systems. They do not create any new systems interactions. Therefore, the proposed change does not increase or have any impact on the consequences of events described and evaluated in Chapter 14 of the Fort Calhoun Updated Safety Analysis Report (USAR).

5.1 Accident Induced Leakage Performance Criterion The Nuclear Energy Institute (NEI) provided members the following information and status report in a letter dated September 2, 2005. NEI stated that this was offered for use in license amendment requests. NEI stated that the following information and status report has been reviewed with the NRC.

The industry is currently evaluating a technical issue related to the Accident Induced Leakage Performance Criterion (AILPC) specified in Section 5.23 of the proposed Technical Specifications. The issue concerns the consideration of non-pressure (bending) loads on the accident induced leak rates of steam generator tubes (axial differential thermal loads are routinely considered in assessing accident induced leakage). The EPRI Steam Generator Management Program (SGMP) is conducting a study to determine if bending loads are significant, and if they are, to define how to account for the loads in steam generator tube integrity assessments. In the interim, as this study is being completed, EPRI has completed a preliminary impact assessment. The assessment (PreliminaryAssessment of the hnpact of Non-PressureLoads on Leakage Integrity of Steam Generator Tubing) found that the effect of the loads in question may, in certain circumstances, initiate primary-to-secondary leakage, or increase pre-existing primary-to-secondary leakage during and after load application. The effort also assessed the effect of such loads in combination with the applicable design basis accident.

The results indicate that these circumstances are expected to be limited to the presence of significant circumferential cracks located in high bending stress regions of tubing. As of this date, such degradation has not been observed in the industry.

The structural integrity impact of non-pressure loads on degraded steam generator tubes has been well-documented in a previous EPRI report (NRC accession number ML050760208) related to the revised Structural Integrity Performance Criterion (SIPC). Experimental results indicated that neither axial loads nor bending loads have a significant effect on the burst pressure of tubing with axial degradation. Similarly, these loads are considered inconsequential for axially oriented degradation with respect to localized pop-through conditions and corresponding accident leakage. As such, industry experience indicates that the only meaningful impact of non-pressure loads with respect to leakage is due to the application of bending moments on circumferential cracking.

The EPRI Preliminary Assessment found that high bending loads that could affect the leakage analysis are only present in the top span region in the original design of once-through steam generators (OTSGs) and in the U-bend region of large-radius tubes in some recirculating steam generators. The high bending loads in the OTSGs are a consequence of crossflow during a steam line break whereas the high bending loads in the recirculating steam generators are a result of a seismic event.

LIC-06-0087 Page 5 After review of available analysis and experimental data, the EPRI Assessment concluded that the effect of high bending loads is only noteworthy for large 100% or near through-wall circumferential degradation. From a degradation assessment perspective, the EPRI study also reported that current industry experience indicates that there have been no observed stress corrosion circumferential cracks that are both capable of leaking and located in high bending stress regions. The industry's preliminary impact assessment and the plans for further technical study and experimental testing were presented to the NRC Staff in meetings on August 12, 2005 and July 12, 2006. The NRC Staff did not have any significant comments on the results presented.

Based on the above, OPPD believes that the effect of bending loads is not safety significant for FCS with respect to leakage integrity given the expected effect and existing margins with respect to degradation type, susceptible location and allowable flaw size.

If upon completion of EPRI's technical study, it is concluded that the effect of non-pressure loads, including bending loads, should be specifically accounted for in integrity assessments, the industry will revise the applicable steam generator program guideline documents to reflect the means developed to account for the loads.

6.0 REGULATORY ANALYSIS

A description of this proposed change and its relationship to applicable regulatory requirements and guidance was provided in the NRC Notice of Availability published on May 6, 2005 (70 FR 24126), the NRC Notice for Comment published on March 2, 2005 (70 FR 10298), and TSTF-449, Revision 4.

6.1 Verification and Commitments The following information is provided to support the NRC staff's review of this Amendment Application:

LIC-06-0087 Page 6 Plant Name, Unit No. Fort Calhoun Station Unit No. 1 Steam Generator Model(s): Mitsubishi Model: 49TT-1 Effective Full Power Years 0 EFPY (EFPY) of service for currently installed SGs Tubing Material Alloy 690TT Number of tubes per SG 5200 Number and percentage of tubes 1 tube in SG RC-2B (0.0 19%)

plugged in each SG Number of tubes repaired in each 0 SG Degradation mechanism(s) None identified Current primary-to-secondary 150 gallons per day through any one steam leakage limits: generator at standard temperature.

Approved Alternate Tube Repair None Criteria (ARC):

Approved SG Tube Repair Tubes found by inservice inspection to contain Methods flaws with a depth equal to or exceeding 40%

of the nominal tube wall thickness shall be plugged.

Performance criteria for accident 1.0 gallon per minute at standard temperature.

Leakage 7.0 NO SIGNIFICANT HAZARDS CONSIDERATION OPPD has reviewed the proposed no significant hazards consideration determination published on March 2, 2005 (70 FR 10298) as part of the CLIIP. OPPD has concluded that the proposed determination presented in the notice is applicable to FCS and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

LIC-06-0087 Page 7 OPPD has evaluated whether or not a significant hazards consideration is involved with the proposed amendment to delete steam generator tube sleeving as an alternative to plugging for steam generator tube repairs by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

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

Response: No.

The elimination from the TS surveillance requirements of leak tight sleeves as a repair method alternative to plugging defective steam generator tubes does not introduce an initiator to any previously evaluated accident. The frequency or periodicity of performance of the remaining surveillance requirements for steam generator tubes (including plugged tubes) is not affected by this change.

Elimination of the tube repair method has no effect on the consequences of any previously evaluated accident. The proposed changes will not prevent safety systems from performing their accident mitigation function as assumed in the safety analysis.

Therefore, this change does not involve a significant increase in the probability or consequences of any 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 only affects the TS surveillance requirements. The proposed change is a result of installation of RSGs. The proposed change will eliminate a steam generator tube repair alternative which cannot be utilized or credited for the RSGs. This change will not alter assumptions made in the safety analysis and licensing bases and will not create new or different systems interactions.

Therefore, this change does not create the possibility of a new or different kind of accident from any previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No.

The proposed change deletes surveillance requirements for a steam generator tube repair alternative which will no longer be necessary or applicable. The remaining

LIC-06-0087 Page 8 TS steam generator tube surveillance requirements, including inspection and plugging requirements, will continue to maintain the applicable margin of safety.

Therefore, this TS change does not involve a significant reduction in the margin of safety.

Based on the above, Omaha Public Power District concludes that the proposed amendment to delete steam generator tube sleeving as an alternative to plugging for steam generator tube repairs presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of"no significant hazards consideration" is justified.

In conclusion, 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.

8.0 ENVIRONMENTAL EVALUATION OPPD has reviewed the environmental evaluation included in the model SE published on March 2, 2005 (70 FR 10298) as part of the CLIIP. OPPD has concluded that the staff's findings presented in that evaluation are applicable to FCS and the evaluation is hereby incorporated by reference for this application.

Based on the above considerations, the proposed amendment to delete steam generator tube sleeving as an alternative to plugging for steam generator tube repairs does not involve and will not result in a condition which significantly alters the impact of Fort Calhoun Station on the ehvironment. Thus, the proposed changes meet the eligibility criteria for categorical exclusion set forth in 10 CFR Part 51.22(c)(9), and, pursuant to 10 CFR Part 51.22(b), no environmental assessment need be prepared.

9.0 PRECEDENT The TS changes addressed in TSTF-449, Revision 4, are being made in accordance with the CLIIP. OPPD is not proposing variations or deviations from those TS changes, or the NRC staff's model SE published on March 2, 2005 (70 FR 10298) with the exception that the Basis for the applicable safety analyses has been changed to reflect the FCS-specific Steam Generator Tube Rupture (SGTR) assumptions.

OPPD is also requesting deletion from the FCS TS of the surveillance requirements for a steam generator tube repair alternative which will no longer be necessary or applicable due to installation of RSGs. Removal of unnecessary, inapplicable provisions from TS is an accepted practice.

TECHNICAL SPECIFICATION 2.0 LIMITING CONDITIONS FOR OPERATION 2.1 Reactor Coolant System (Continued) 2.1.4 Reactor Coolant System Leakage Limits Applicability Applies to the leakage rates of the reactor coolant system whenever the reactor coolant temperature (Tcowd) is greater than 210 *F.

Obiective To specify limiting conditions of the reactor coolant system leakage rates.

Specifications To assure safe reactor operation, the following limiting conditions of the reactor coolant system leakage rates must be met:

(1) RCS operational LEAKAGE shall be limited to:

a. No Pressure Boundary LEAKAGE,

b. 1 gpm unidentified LEAKAGE,

c. 10 gpm identified LEAKAGE,

d. 150 gallons per day primary to secondary LEAKAGE through any one steam generator(SG).

(2) If RCS operationalLEAKAGE limits of (1), above, are not met for reasons other than Pressure Boundary LEAKAGE orprimaryto secondary LEAKAGE, then reduce LEAKAGE to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

(3) If the Required Action and associated completion time of (2), above, is not met, OR Pressure Boundary LEAKAGE exists, or primary to secondaryLEAKAGE is not within limits, then be in MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months AND be in MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

(4) To determine leakage to the containment, a containment atmosphere radiation monitor (gaseous or particulate) or dew point instrument, and a containment sump level instrument must be operable.

a. With no containment sump level instrument operable, verify that a containment atmosphere radiation monitor is operable, and restore the containment sump level instrument to operable status within 30 days.

b. With no containment atmosphere radiation monitor and no dewpoint instrument operable, restore either a radiation monitor or dewpoint instrument to operable status within 30 days.

c. With only the dewpoint instrument operable, or with no operable instruments, enter Specification 2.0.1 immediately.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.1 Reactor Coolant System (Continued) 2.1.4 Reactor Coolant System Leakage Limits (Continued)

c. Identified LEAKAGE Up to 10 gpm of identified LEAKAGE is considered allowable because LEAKAGE is from known sources that do not interfere with detection of unidentified LEAKAGE and is well within the capability of the RCS makeup system. Identified LEAKAGE includes LEAKAGE to the containment from specifically known and located sources, but does not include pressure boundary LEAKAGE or controlled reactor coolant pump (RCP) seal leakoff (a normal function not considered LEAKAGE). Violation of this LCO could result in continued degradation of a component or system.

d. Primary to Secondary LEAKAGE through Any One SG The 150 gallon per day operationallimit on primary to secondary LEAKAGE through any one SG is based upon guidance in NEI 97-06, Steam Generator Program Guidelines. The Steam GeneratorProgram operationalLEAKAGE performance Criterionin NEI 97-06 states, "The RCS operationalprimary to secondary leakage through any one SG shall be limited to 150 gallons per day." The limit is based on operatingexperience with SG tube degradationmechanisms that result in tube leakage. The operational leakage rate criterionin conjunction with the implementation of the Steam GeneratorProgramis an effective measure for minimizing the frequency of steam generatortube ruptures.

APPLICABILITY The potential for RCPB LEAKAGE is greatest when the RCS is pressurized, that is, when the reactor coolant temperature (Tc.d) is greater than 210°F.

In MODES 4 and 5, LEAKAGE limits are not required because the reactor coolant pressure is far lower, resulting in lower stresses and reduced potentials for LEAKAGE.

REQUIRED ACTIONS (2).

Unidentified LEAKAGET or identified LEAKAGE, or primary to econdar'; LEAKA.GE in excess of the LCO limits must be reduced to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months . This Completion Time allows time to verify leakage rates and either identify unidentified LEAKAGE or reduce LEAKAGE to within limits before the reactor must be shut down.

This action is necessary to prevent further deterioration of the RCPB.

REQUIRED ACTIONS (3)

If any pressure boundary LEAKAGE exists or primary to secondaryLEAKAGE is not within limits, or if unidentifiedT or identified, or primar'-' to socondary LEAKAGE cannot be reduced to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , the reactor must be brought to lower pressure conditions to reduce the severity of the LEAKAGE and its potential consequences. The reactor must be brought to MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and to MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . This action reduces the LEAKAGE and also reduces the factors that tend to degrade the pressure boundary.

The allowed Completion Times are reasonable, based on operating experience, to reach the required conditions from full power conditions in an orderly manner and without challenging plant systems. In MODE 4, the pressure stresses acting on the RCPB are much lower, and further deterioration is much less likely.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator(SG) Tube Integrity Applicability Applies whenever the reactorcoolant temperature (Tco1d) is greaterthan 210 0F.

Objective To ensure that SG tube integrity is maintained.

Specification NOTE: Separate Condition entry is allowed for each SG Tube.

(1) The following conditions shall be maintained:

(a) SG tube Integrityshall be maintained,and (b)All SG tubes satisfying the tube repaircriteria shall be plugged in accordance with the Steam GeneratorProgram.

(2) If the requirementsof (1)(b) above are not met for one or more SG tubes, then perform the following.

(a) Verify tube integrity of the affected tube(s) is maintaineduntil the next refueling outage or SG tube inspection within 7 days, and (b) Plug the affected tube(s) in accordance with the Steam GeneratorProgrampriorto exceeding 210°F reactorcoolant temperature(TC,,d) following the next refueling outage or SG tube inspection.

(3) If the RequiredAction and associatedcompletion time of (2), above, is not met, or if SG tube integrity is not maintained,then be in MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months AND be in MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

Basis Steam generator(SG) tubes are small diameter,thin walled tubes that carry primary coolant through the primary to secondary heat exchangers. The SG tubes have a number of important safety functions. Steam generator tubes are an integralpart of the reactorcoolantpressure boundary (RCPB) and, as such, are relied on to maintain the primary system's pressure and inventory. The SG tubes isolate the radioactivefission products in the primary coolant from the secondary system. In addition,as part of the RCPB, the SG tubes are unique in that they act as the heat transfersurface between the primary and secondary systems to remove heat from the primarysystem. This Specification addressesonly the RCPB integrity function of the SG. The SG heat removal function is addressedby Technical Specification 2.1.1, "OperableComponents."

SG tube integrity means that the tubes are capable of performing their intended RCPB safety function consistent with the licensing basis, including applicable regulatoryrequirements.

2.23 - Page 1 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator(SG) Tube Integrity (continued)

Steam generatortubing is subject to a variety of degradationmechanisms. Steam generatortubes may experience tube degradationrelated to corrosion phenomena, such as wastage, pitting, intergranularattack, and stress corrosion cracking, along with other mechanically inducedphenomena such as denting and wear. These degradationmechanisms can impair tube integrity if they are not managed effectively. The SG performance criteriaare used to manage SG tube degradation.

Specification 5.23, "Steam Generator(SG) Program,"requires that a program be established and implemented to ensure that SG tube integrity is maintained. Pursuantto Specification 5.23, tube integrity is maintained when the SG performance criteriaare met. There are three SG performance criteria:structuralintegrity, accident induced leakage, and operationalLEAKAGE. The SG performance criteria are described in Specification 5.23.

Meeting the SG performance criteriaprovides reasonableassuranceof maintaining tube integrity at normal and accident conditions.

The processes used to meet the SG performance criteria are defined by the Steam GeneratorProgram Guidelines (Ref. 1).

The steam generatortube rupture (SGTR) accident is the limiting design basis event for SG tubes and avoiding an SGTR is the basis for this Specification. The analysis of a SGTR event assumes a bounding primary to secondaryLEAKAGE rate equal to the operationalLEAKAGE rate limits in Technical Specification 2.1.4, "ReactorCoolant System Leakage Limits," plus the leakage rate associatedwith a double-ended rupture of a single tube. The accident analysis for a SGTR assumes releasesof activity occur from the faulted steam generatorto the environment via the condenser air ejector and Main Steam Safety Valves (MSSVs) and Atmospheric Dump Valves (ADVs). The release via the condenserairejector starts at the initiationof the event and continues to the reactortrip, while the release via the MSSVs/ADVs starts at the reactortrip and continues for the duration of the event."

The analysis for design basis accidents and transientsother than a SGTR assume the SG tubes retain their structuralintegrity (i.e., they are assumednot to rupture.) In these analyses, the steam discharge to the atmosphere is based on the totalprimary to secondary LEAKAGE from all SGs of I gallon per minute or is assumed to increase to 1 gallon per minute as a result of accident induced conditions. Foraccidents that do not involve fuel damage, the primary coolant activity level of DOSE EQUIVALENT 1-131 is assumed to be equal to the Technical Specification 2.1.3, "ReactorCoolant Radioactivity," limits. Foraccidents that assume fuel damage, the primary coolant activity is a function of the amount of activity released from the damaged fuel. The dose consequences of these events are within the limits of GDC 19 (Ref. 2), 10 CFR 100 (Ref. 3) or the NRC approvedlicensing basis (e.g., a small fraction of these limits).

Steam generatortube integrity satisfies Criterion2 of 10 CFR 50.36(c)(2)(ii). The LCO requires that SG tube integrity be maintained. The LCO also requires that all SG tubes that satisfy the repaircriteriabe plugged in accordancewith the Steam GeneratorProgram.

Duringan SG inspection, any inspected tube that satisfies the Steam GeneratorProgramrepaircriteriais removed from service by plugging. If a tube was determined to satisfy the repaircriteria but was not plugged, the tube may still have tube integrity.

In the context of this Specification, a SG tube is defined as the entire length of the tube, including the tube wall, between the tube-to-tubesheet weld at the tube inlet and the tube-to-tubesheet weld at the tube outlet. The tube-to-tubesheet weld is not consideredpart of the tube.

A SG tube has tube integrity when it satisfies the SG performance criteria. The SG performance criteriaare defined in Specification 5.23, "Steam GeneratorProgram,"and describe acceptable SG tube performance. The Steam GeneratorProgramalso provides the evaluationprocess for determining conformance with the SG performance criteria.

There are three SG performance criteria:structuralintegrity,accident induced leakage, and operational LEAKAGE. Failure to meet any one of these criteriais consideredfailure to meet the LCO.

2.23 - Page 2 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator(SG) Tube Integrity (continued)

The structuralintegrityperformance criterionprovides a margin of safety againsttube burst or collapse under normal and accident conditions, and ensures structuralintegrity of the SG tubes under all anticipatedtransients included in the design specification. Tube burst is defined as, "The gross structuralfailure of the tube wall. The condition typically corresponds to an unstable opening displacement (e.g., opening area increasedin response to constant pressure)accompaniedby ductile (plastic)tearing of the tube materialat the ends of the degradation." Tube collapse is defined as, "Forthe load displacementcurve for a given structure, collapse occurs at the top of the load versus displacement curve where the slope of the curve becomes zero." The structuralintegrityperformance criterionprovides guidance on assessingloads that have a significant effect on burst or collapse. In that context, the term "significant"is defined as "An accident loading condition other than differentialpressure is consideredsignificant when the addition of such loads in the assessment of the structural integrity performance criterioncould cause a lower structurallimit or limiting burst/collapsecondition to be established." Fortube integrity evaluations,except for circumferentialdegradation,axial thermal loads are classified as secondaryloads. For circumferentialdegradation,the classificationof axial thermal loads as primary or secondaryloads will be evaluated on a case-by-case basis. The division between primary and secondary classificationswill be based on detailedanalysis and/ortesting.

Structuralintegrity requires that the primary membrane stress intensity in a tube not exceed the yield strength for all ASME Code,Section III, Service Level A (normaloperatingconditions) and Service Level B (upset or abnormalconditions) transients included in the design specification. This includes safety factors and applicable design basis loads based on ASME Code,Section III, Subsection NB (Ref. 4) and Draft Regulatory Guide 1.121 (Ref. 5).

The accident induced leakage performance criterion ensures that the primary to secondaryLEAKAGE caused by a design basis accident, other than a SGTR, is within the accident analysis assumptions. The accident analysis assumes that accident induced leakage does not exceed I gpm per SG. The accident induced leakage rate includes any primaryto secondary LEAKAGE existing priorto the accident in addition to primary to secondaryLEAKAGE induced during the accident.

The operationalLEAKAGE performance criterionprovides an observable indication of SG tube conditions during plant operation. The limit on operationalLEAKAGE is containedin Technical Specification 2.1.4. Reactor Coolant System Leakage Limits," and limits primary to secondaryLEAKAGE through any one SG to 150 gallons per day. This limit is based on the assumption that a single crack leaking this amount would not propagate to a SGTR under the stress conditions of a LOCA ora main steam line break. If this amount of LEAKAGE is due to more than one crack, the cracks are very small, and the above assumption is conservative.

Steam generatortube integrity is challenged when the pressuredifferential across the tubes is large. Large differentialpressures across SG tubes can only be experienced when Tcold is > 210°F.

RCS conditions are far less challenging in MODES 4 and 5 than during MODES 1, 2, and 3. In MODES 4 and 5, primary to secondary differentialpressure is low, resultingin lower stresses and reduced potentialfor LEAKAGE.

The ACTIONS are modified by a Note clarifying that the Conditions may be entered independentlyfor each SG tube. This is acceptable because the Required Actions provide appropriatecompensatory actions for each affected SG tube. Complying with the Required Actions may allow for continued operation,and subsequent affected SG tubes are governed by subsequent Condition entry and applicationof associatedRequired Actions.

Specification 2.23(2) applies if it is discovered that one or more SG tubes examined in an inservice inspection satisfy the tube repaircriteriabut were not plugged in accordance with the Steam GeneratorProgramas requiredby Technical Specification 3.17. An evaluation of SG tube integrity of the affected tube(s) must be made. Steam generatortube integrity is based on meeting the SG performance criteriadescribed in the Steam GeneratorProgram.

2.23 - Page 3 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator(SG) Tube Integrity (continued)

The SG repaircriteriadefine limits on SG tube degradationthat allow for flaw growth between inspections while still providing assurancethat the SG performance criteria will continue to be met. In orderto determine if a SG tube that should have been plugged has tube integrity,an evaluation must be completed that demonstrates that the SG performance criteria will continue to be met until the next refueling outage or SG tube inspection. The tube integrity determinationis based on the estimated condition of the tube at the time the situation is discovered and the estimated growth of the degradationpriorto the next SG tube inspection. If it is determined that tube integrity is not being maintained,Specification 2.23(3) applies.

A Completion Time of 7 days is sufficient to complete the evaluationwhile minimizing the risk of plant operationwith a SG tube that may not have tube integrity.

If the evaluationdetermines that the affected tube(s) have tube integrity, Required Action 2.23(2)b allows plant operation to continue until the next refueling outage or SG inspection provided the inspection interval continues to be supported by an operationalassessment that reflects the affected tubes. However, the affected tube(s) must be plugged priorto exceeding 210°F reactorcoolant temperature(Tecod) following the next refueling outage or SG inspection. This Completion Time is acceptable since operation until the next inspection is supported by the operationalassessment.

If the Required Actions and associated Completion Times of Technical Specification 2.23(2) are not met or if SG tube integrity is not being maintained,the reactormust be brought to MODE 3 within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and MODE 4 within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

The allowed Completion Times are reasonable,based on operatingexperience, to reach the desiredplant conditions from full power conditions in an orderly manner and without challengingplant systems.

The Safety Injection (SI) pump room air treatment system consists of charcoal adsorbers which are installed in normally bypassed ducts. This system is designed to reduce the potential release of radioiodine in SI pump rooms during the recirculation period following a DBA. The in-place and laboratory testing of charcoal adsorbers will assure system integrity and performance.

Pressure drops across the combined HEPA filters and charcoal adsorbers, of less than 9 inches of water for the control room filters (VA-64A & VA-64B) and of less than 6 inches of water for each of the other air treatment systems will indicate that the filters and adsorbers are not clogged by amounts of foreign matter that would interfere with performance to established levels. Operation of each system for 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months every month will demonstrate operability and remove excessive moisture build-up in the adsorbers.

The hydrogen purge system provides the control of combustible gases (hydrogen) in containment for a post-LOCA environment. The surveillance tests provide assurance that the system is operable and capable of performing its design function. VA-80A or VA-80B is capable of controlling the expected hydrogen generation (67 SCFM) associated with 1) Zirconium - water reactions, 2) radiolytic decomposition of sump water and 3) corrosion of metals within containment. The system should have a minimum of one blower with associated valves and piping (VA-80A or VA-80B) available at all times to meet the guidelines of Regulatory Guide 1.7 (1971).

If significant painting, fire or chemical release occurs such that the HEPA filters or charcoal adsorbers could become contaminated from the fumes, chemicals or foreign materials, testing will be performed to confirm system performance.

Demonstration of the automatic and/or manual initiation capability will assure the system's availability.

Verifying Reactor Coolant System (RCS) leakage to be within the LCO limits ensures the integrity of the Reactor Coolant Pressure Boundary (RCPB) is maintained. Pressure boundary leakage would at first appear as unidentified leakage and can only be positively identified by inspection. Unidentified leakage is determined by performance of an RCS water inventory balance. Identified leakage is then determined by isolation and/or inspection. Since Primaryto Secondary Leakage of 150 gallons per day cannot be measured accuratelyby an RCS water inventory balance, note "..." for line item 8a on Table 3-5 states that the Reactor Coolant System Leakage surveillanceis not applicableto Primaryto Secondary Leakage.

Primary to secondary leakage is-also measured by performance of an RCS water invonto,'y ba!ance in conjunction with effluent monitoring within the secondary steam and feedwater systems.

Table 3-5, Item 8b verifies that primary to secondary LEAKAGE is less or equal to 150 gallons per day through any one SG. Satisfying the primary to secondary LEAKAGE limit ensures that the operationalLEAKAGE performance criterion in the Steam GeneratorProgram is met. If this surveillance requirementis not met, compliance with LCO 2.23, "Steam Generator(SG) Tube Integrity," should be evaluated. The 150 gallons per day limit is measured at room temperature as describedin Reference 5. The operationalLEAKAGE rate limit applies to LEAKAGE through any one SG. If it is not practicalto assign the LEAKAGE to an individual SG, all the primary to secondaryLEAKAGE should be conservatively assumed to be from one SG.

The Surveillance is modified by a Note which states that the Surveillance is not requiredto be performed until 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months after establishmentof steady state operation. ForRCS primary to secondary LEAKAGE determination,steady state is defined as stable RCS pressure,temperature,power level, pressurizerand makeup tank levels, makeup and letdown, and RCP seal injection and return flows.

The Surveillance Frequency of daily is a reasonable interval to trend primary to secondaryLEAKAGE and recognizes the importance of early leakage detection in the prevention of accidents. The primary to secondary LEAKAGE is determined using continuous process radiationmonitors or radiochemicalgrab sampling in accordancewith the EPRI guidelines (Ref. 5).

TECHNICAL SPECIFICATIONS 3.0 SURVEILLANCE REQUIREMENTS 3.17 Steam Generator Tubes (Continued)

Basis Duringshutdown periods the SGs are inspected as required by this Surveillance requirement (SR) and the Steam GeneratorProgram. NEI 97-06, Steam GeneratorProgram Guidelines (Ref. 1), and its referenced EPRI Guidelines, establish the content of the Steam GeneratorProgram. Use of the Steam GeneratorProgram ensures that the inspection is appropriateand consistent with accepted industry practices.

During SG inspections a condition monitoringassessment of the SG tubes is performed. The condition monitoring assessment determines the "asfound" condition of the SG tubes. The purpose of the condition monitoring assessment is to ensure that the SG performance criteriahave been met for the previous operatingperiod.

The Steam GeneratorProgramdetermines the scope of the inspection and the methods used to determine whether the tubes contain flaws satisfying the tube repaircriteria. Inspection scope (i.e.,

which tubes or areas of tubing within the SG are to be inspected)is a function of existing and potential degradationlocations. The Steam GeneratorProgramalso specifies the inspection methods to be used to find potential degradation. Inspection methods are a function of degradationmorphology, non-destructive examination (NDE) technique capabilities,and inspection locations.

The Steam GeneratorProgram defines the Frequencyof SR 3.17(1). The Frequency is determined by the operationalassessment and otherlimits in the SG examination guidelines (Ref. 6). The Steam GeneratorProgramuses information on existing degradationsand growth rates to determine an inspection Frequencythat provides reasonableassurancethat the tubing will meet the SG performance criteriaat the next scheduled inspection. In addition, Specification 5.23 contains prescriptive requirementsconcerning inspection intervals to provide added assurance that the SG performance criteriawill be met between scheduled inspections.

Duringan SG inspection, any inspectedtube that satisfies the Steam GeneratorProgram repaircriteria is removed from service by plugging. The tube repaircriteriadelineatedin Specification 5.23 are intended to ensure that tubes accepted for continued service satisfy the SG performance criteriawith allowance for errorin the flaw size measurement and for future flaw growth. In addition, the tube repair criteria, in conjunction with otherelements of the Steam GeneratorProgram,ensure that the SG performance criteriawill continue to be met until the next inspection of the subject tube(s). Reference 1 provides guidance for performing operationalassessments to verify that the tubes remaining in service will continue to meet the SG performance criteria.

The Frequency of priorto exceeding 21 0°F reactorcoolant temperature (Tcoid) following a SG inspection ensures that the Surveillance has been completed and all tubes meeting the repaircriteriaare plugged priorto subjecting the SG tubes to significant primary to secondarypressure differential.

TECHNICAL SPECIFICATIONS 5.0 ADMINISTRATIVE CONTROLS 5.23 Steam Generator(SG) Program A Steam GeneratorProgramshallbe establishedand implemented to ensure that SG tube integrity is maintained. In addition, the Steam GeneratorProgramshallinclude the following provisions:

a. Provisions for condition monitoring assessments. Condition monitoring assessment means an evaluation of the "asfound" condition of the tubing with respect to the performance criteriafor structuralintegrity and accident induced leakage. The "asfound" condition refers to the condition of the tubing during an SG inspection outage, as determined from the inservice inspection results or by othermeans, priorto the plugging of tubes. Condition monitoring assessments shall be conducted during each outage during which the SG tubes are inspected or plugged to confirm that the performance criteriaare being met.

b. Performance criteriafor SG tube integrity. SG tube integrityshall be maintainedby meeting the performance criteriafor tube structuralintegrity, accident induced leakage, and operational LEAKAGE.

1. Structuralintegrityperformance criterion: All in-service steam generatortubes shall retain structuralintegrity over the full range of normal operatingconditions (includingstartup, operationin the power range, hot standby, and cool down and all anticipatedtransients included in the design specification)and design basis accidents. This includes retaining a safety factor of 3.0 against burst undernormal steady state full power operation primary-to-secondarypressure differentialand a safety factor of 1.4 against burst applied to the design basis accident primary-to-secondarypressure differentials.Apart from the above requirements, additionalloading conditions associatedwith the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine if the associatedloads contribute significantly to burst or collapse. In the assessment of tube integrity, those loads that do significantlyaffect burst or collapse shall be determined and assessedin combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondaryloads.

2. Accident induced leakage performance criterion: The primary to secondaryaccident induced leakage rate for any design basis accident, other than a SG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of totalleakage rate for all SGs and leakage rate for an individual SG. Leakage is not to exceed I gpm per SG.

3. The operationalLEAKAGE performance criterion is specified in LCO 2.1.4, "ReactorCoolant System Leakage Limits."

c. Provisionsfor SG tube repaircriteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged.

5.0 - Page 19 Amendment No.

TECHNICAL SPECIFICATIONS 5.0 ADMINISTRATIVE CONTROLS 5.23 Steam Generator(SG) Program (continued)

d. Provisions for SG tube inspections. PeriodicSG tube inspections shall be performed. The number and portions of the tubes inspectedand methods of inspection shall be performed with the objective of detecting flaws of any type (e.g., volumetric flaws, axial and circumferentialcracks) that may be present along the length of the tube, from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicabletube repaircriteria. The tube-to-tubesheet weld is not part of the tube. In addition to meeting the requirementsof d.1, d.2, and d.3 below, the inspection scope, inspection methods, and inspection intervals shall be such as to ensure that SG tube integrity is maintained until the next SG inspection. An assessment of degradationshall be performed to determine the type and location of flaws to which the tubes may be susceptible and, based on this assessment, to determine which inspection methods need to be employed and at what locations.

1. Inspect 100% of the tubes in each SG during the first refueling outage following SG replacement.

2. Inspect 100% of the tubes at sequentialperiods of 144, 108, 72, and, thereafter, 60 effective full power months. The first sequentialperiod shall be consideredto begin after the first inservice inspection of the SGs. In addition,inspect 50% of the tubes by the refueling outage nearest the midpoint of the period and the remaining50% by the refueling outage nearestthe end of the period. No SG shall operate for more than 72 effective full power months or three refueling outages (whichever is less) without being inspected.

3. If crack indications are found in any SG tube, then the next inspection for each SG for the degradationmechanism that caused the crack indication shall not exceed 24 effective full power months or one refueling outage (whichever is less). If definitive information, such as from examination of a pulled tube, diagnosticnon-destructive testing, or engineeringevaluation indicates that a crack-like indicationis not associatedwith a crack(s), then the indication need not be treatedas a crack.

e. Provisions for monitoring operationalprimary to secondaryLEAKAGE.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.1 Reactor Coolant System (Continued) 2.1.4 Reactor Coolant System Leakage Limits Applicability Applies to the leakage rates of the reactor coolant system whenever the reactor coolant temperature (TCOld) is greater than 210 OF.

Obiective To specify limiting conditions of the reactor coolant system leakage rates.

Specifications To assure safe reactor operation, the following limiting conditions of the reactor coolant system leakage rates must be met:

(1) RCS operational LEAKAGE shall be limited to:

a. No Pressure Boundary LEAKAGE,

b. 1 gpm unidentified LEAKAGE,

c. 10 gpm identified LEAKAGE,

d. 150 gallons per day primary to secondary LEAKAGE through any one steam generator (SG).

(2) If RCS operational LEAKAGE limits of (1), above, are not met for reasons other than Pressure Boundary LEAKAGE or primary to secondary LEAKAGE, then reduce LEAKAGE to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months .

(3) If the Required Action and associated completion time of (2), above, is not met, OR Pressure Boundary LEAKAGE exists, or primary to secondary LEAKAGE is not within limits, then be in MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months AND be in MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

(4) To determine leakage to the containment, a containment atmosphere radiation monitor (gaseous or particulate) or dew point instrument, and a containment sump level instrument must be operable.

a. With no containment sump level instrument operable, verify that a containment atmosphere radiation monitor is operable, and restore the containment sump level instrument to operable status within 30 days.

b. With no containment atmosphere radiation monitor and no dewpoint instrument operable, restore either a radiation monitor or dewpoint instrument to operable status within 30 days.

c. With only the dewpoint instrument operable, or with no operable instruments, enter Specification 2.0.1 immediately.

2.1 - Page 13 Amendment No. 32,165,195,

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.1 Reactor Coolant System (Continued) 2.1.4 Reactor Coolant System Leakage Limits (Continued)

c. Identified LEAKAGE Up to 10 gpm of identified LEAKAGE is considered allowable because LEAKAGE is from known sources that do not interfere with detection of unidentified LEAKAGE and is well within the capability of the RCS makeup system. Identified LEAKAGE includes LEAKAGE to the containment from specifically known and located sources, but does not include pressure boundary LEAKAGE or controlled reactor coolant pump (RCP) seal leakoff (a normal function not considered LEAKAGE). Violation of this LCO could result in continued degradation of a component or system.

d. Primary to Secondary LEAKAGE through Any One SG The 150 gallon per day operational limit on primary to secondary LEAKAGE through any one SG is based upon guidance in NEI 97-06, Steam Generator Program Guidelines. The Steam Generator Program operational LEAKAGE performance Criterion in NEI 97-06 states, "The RCS operational primary to secondary leakage through any one SG shall be limited to 150 gallons per day." The limit is based on operating experience with SG tube degradation mechanisms that result in tube leakage. The operational leakage rate criterion in conjunction with the implementation of the Steam Generator Program is an effective measure for minimizing the frequency of steam generator tube ruptures.

APPLICABILITY The potential for RCPB LEAKAGE is greatest when the RCS is pressurized, that is, when the reactor coolant temperature (Tco1d) is greater than 210°F.

In MODES 4 and 5, LEAKAGE limits are not required because the reactor coolant pressure is far lower, resulting in lower stresses and reduced potentials for LEAKAGE.

REQUIRED ACTIONS (2).

Unidentified LEAKAGE or identified LEAKAGE in excess of the LCO limits must be reduced to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months . This Completion Time allows time to verify leakage rates and either identify unidentified LEAKAGE or reduce LEAKAGE to within limits before the reactor must be shut down. This action is necessary to prevent further deterioration of the RCPB.

REQUIRED ACTIONS (3)

If any pressure boundary LEAKAGE exists or primary to secondary LEAKAGE is not within limits, or if unidentified or identified LEAKAGE cannot be reduced to meet limits within 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months , the reactor must be brought to lower pressure conditions to reduce the severity of the LEAKAGE and its potential consequences.

The reactor must be brought to MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and to MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . This action reduces the LEAKAGE and also reduces the factors that tend to degrade the pressure boundary.

The allowed Completion Times are reasonable, based on operating experience, to reach the required conditions from full power conditions in an orderly manner and without challenging plant systems. In MODE 4, the pressure stresses acting on the RCPB are much lower, and further deterioration is much less likely.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator (SG) Tube Integrity Applicability Applies whenever the reactor coolant temperature (Tcoid) is greater than 21 0°F.

Obiective To ensure that SG tube integrity is maintained.

Specification NOTE: Separate Condition entry is allowed for each SG Tube.

(1) The following conditions shall be maintained:

(a) SG tube Integrity shall be maintained, and (b) All SG tubes satisfying the tube repair criteria shall be plugged in accordance with the Steam Generator Program.

(2) If the requirements of (1)(b) above are not met for one or more SG tubes, then perform the following:

(a) Verify tube integrity of the affected tube(s) is maintained until the next refueling outage or SG tube inspection within 7 days, and (b) Plug the affected tube(s) in accordance with the Steam Generator Program prior to exceeding 210°F reactor coolant temperature (Tcold) following the next refueling outage or SG tube inspection.

(3) If the Required Action and associated completion time of (2), above, is not met, or if SG tube integrity is not maintained, then be in MODE 3, Hot Shutdown, within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months AND be in MODE 4, Cold Shutdown, within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

Basis Steam generator (SG) tubes are small diameter, thin walled tubes that carry primary coolant through the primary to secondary heat exchangers. The SG tubes have a number of important safety functions. Steam generator tubes are an integral part of the reactor coolant pressure boundary (RCPB) and, as such, are relied on to maintain the primary system's pressure and inventory. The SG tubes isolate the radioactive fission products in the primary coolant from the secondary system. In addition, as part of the RCPB, the SG tubes are unique in that they act as the heat transfer surface between the primary and secondary systems to remove heat from the primary system. This Specification addresses only the RCPB integrity function of the SG. The SG heat removal function is addressed by Technical Specification 2.1.1, "Operable Components."

SG tube integrity means that the tubes are capable of performing their intended RCPB safety function consistent with the licensing basis, including applicable regulatory requirements.

2.23 - Page 1 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator (SG) Tube Integrity (continued)

Steam generator tubing is subject to a variety of degradation mechanisms. Steam generator tubes may experience tube degradation related to corrosion phenomena, such as wastage, pitting, intergranular attack, and stress corrosion cracking, along with other mechanically induced phenomena such as denting and wear.

These degradation mechanisms can impair tube integrity ifthey are not managed effectively. The SG performance criteria are used to manage SG tube degradation.

Specification 5.23, "Steam Generator (SG) Program," requires that a program be established and implemented to ensure that SG tube integrity is maintained. Pursuant to Specification 5.23, tube integrity is maintained when the SG performance criteria are met. There are three SG performance criteria: structural integrity, accident induced leakage, and operational LEAKAGE. The SG performance criteria are described in Specification 5.23. Meeting the SG performance criteria provides reasonable assurance of maintaining tube integrity at normal and accident conditions.

The processes used to meet the SG performance criteria are defined by the Steam Generator Program Guidelines (Ref. 1).

The steam generator tube rupture (SGTR) accident is the limiting design basis event for SG tubes and avoiding an SGTR is the basis for this Specification. The analysis of a SGTR event assumes a bounding primary to secondary LEAKAGE rate equal to the operational LEAKAGE rate limits in Technical Specification 2.1.4, "Reactor Coolant System Leakage Limits," plus the leakage rate associated with a double-ended rupture of a single tube. The accident analysis for a SGTR assumes releases of activity occur from the faulted steam generator to the environment via the condenser air ejector and Main Steam Safety Valves (MSSVs) and Atmospheric Dump Valves (ADVs). The release via the condenser air ejector starts at the initiation of the event and continues to the reactor trip, while the release via the MSSVs/ADVs starts at the reactor trip and continues for the duration of the event."

The analysis for design basis accidents and transients other than a SGTR assume the SG tubes retain their structural integrity (i.e., they are assumed not to rupture.) In these analyses, the steam discharge to the atmosphere is based on the total primary to secondary LEAKAGE from all SGs of 1 gallon per minute or is assumed to increase to 1 gallon per minute as a result of accident induced conditions. For accidents that do not involve fuel damage, the primary coolant activity level of DOSE EQUIVALENT 1-131 is assumed to be equal to the Technical Specification 2.1.3, "Reactor Coolant Radioactivity," limits. For accidents that assume fuel damage, the primary coolant activity is a function of the amount of activity released from the damaged fuel. The dose consequences of these events are within the limits of GDC 19 (Ref. 2), 10 CFR 100 (Ref. 3) or the NRC approved licensing basis (e.g., a small fraction of these limits).

Steam generator tube integrity satisfies Criterion 2 of 10 CFR 50.36(c)(2)(ii). The LCO requires that SG tube integrity be maintained. The LCO also requires that all SG tubes that satisfy the repair criteria be plugged in accordance with the Steam Generator Program.

During an SG inspection, any inspected tube that satisfies the Steam Generator Program repair criteria is removed from service by plugging. If a tube was determined to satisfy the repair criteria but was not plugged, the tube may still have tube integrity.

In the context of this Specification, a SG tube is defined as the entire length of the tube, including the tube wall, between the tube-to-tubesheet weld at the tube inlet and the tube-to-tubesheet weld at the tube outlet.

The tube-to-tubesheet weld is not considered part of the tube.

A SG tube has tube integrity when it satisfies the SG performance criteria. The SG performance criteria are defined in Specification 5.23, "Steam Generator Program," and describe acceptable SG tube performance.

The Steam Generator Program also provides the evaluation process for determining conformance with the SG performance criteria.

There are three SG performance criteria: structural integrity, accident induced leakage, and operational LEAKAGE. Failure to meet any one of these criteria is considered failure to meet the LCO.

2.23 - Page 2 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator (SG) Tube Inteqrity (continued)

The structural integrity performance criterion provides a margin of safety against tube burst or collapse under normal and accident conditions, and ensures structural integrity of the SG tubes under all anticipated transients included in the design specification. Tube burst is defined as, "The gross structural failure of the tube wall. The condition typically corresponds to an unstable opening displacement (e.g., opening area increased in response to constant pressure) accompanied by ductile (plastic) tearing of the tube material at the ends of the degradation." Tube collapse is defined as, "For the load displacement curve for a given structure, collapse occurs at the top of the load versus displacement curve where the slope of the curve becomes zero."

The structural integrity performance criterion provides guidance on assessing loads that have a significant effect on burst or collapse. In that context, the term "significant" is defined as "An accident loading condition other than differential pressure is considered significant when the addition of such loads in the assessment of the structural integrity performance criterion could cause a lower structural limit or limiting burst/collapse condition to be established." For tube integrity evaluations, except for circumferential degradation, axial thermal loads are classified as secondary loads. For circumferential degradation, the classification of axial thermal loads as primary or secondary loads will be evaluated on a case-by-case basis. The division between primary and secondary classifications will be based on detailed analysis and/or testing.

Structural integrity requires that the primary membrane stress intensity in a tube not exceed the yield strength for all ASME Code, Section Ill, Service Level A (normal operating conditions) and Service Level B (upset or abnormal conditions) transients included in the design specification. This includes safety factors and applicable design basis loads based on ASME Code,Section III, Subsection NB (Ref. 4) and Draft Regulatory Guide 1.121 (Ref. 5).

The accident induced leakage performance criterion ensures that the primary to secondary LEAKAGE caused by a design basis accident, other than a SGTR, is within the accident analysis assumptions. The accident analysis assumes that accident induced leakage does not exceed I gpm per SG. The accident induced leakage rate includes any primary to secondary LEAKAGE existing prior to the accident in addition to primary to secondary LEAKAGE induced during the accident.

The operational LEAKAGE performance criterion provides an observable indication of SG tube conditions during plant operation. The limit on operational LEAKAGE is contained in Technical Specification 2.1.4.

Reactor Coolant System Leakage Limits," and limits primary to secondary LEAKAGE through any one SG to 150 gallons per day. This limit is based on the assumption that a single crack leaking this amount would not propagate to a SGTR under the stress conditions of a LOCA or a main steam line break. If this amount of LEAKAGE is due to more than one crack, the cracks are very small, and the above assumption is conservative.

Steam generator tube integrity is challenged when the pressure differential across the tubes is large. Large differential pressures across SG tubes can only be experienced when Tco;d is > 210°F.

RCS conditions are far less challenging in MODES 4 and 5 than during MODES 1, 2, and 3. In MODES 4 and 5, primary to secondary differential pressure is low, resulting in lower stresses and reduced potential for LEAKAGE.

The ACTIONS are modified by a Note clarifying that the Conditions may be entered independently for each SG tube. This is acceptable because the Required Actions provide appropriate compensatory actions for each affected SG tube. Complying with the Required Actions may allow for continued operation, and subsequent affected SG tubes are governed by subsequent Condition entry and application of associated Required Actions.

Specification 2.23(2) applies if it is discovered that one or more SG tubes examined in an inservice inspection satisfy the tube repair criteria but were not plugged in accordance with the Steam Generator Program as required by Technical Specification 3.17. An evaluation of SG tube integrity of the affected tube(s) must be made. Steam generator tube integrity is based on meeting the SG performance criteria described in the Steam Generator Program.

2.23 - Page 3 Amendment No.

TECHNICAL SPECIFICATIONS 2.0 LIMITING CONDITIONS FOR OPERATION 2.23 Steam Generator (SG) Tube Integrity (continued)

The SG repair criteria define limits on SG tube degradation that allow for flaw growth between inspections while still providing assurance that the SG performance criteria will continue to be met. In order to determine if a SG tube that should have been plugged has tube integrity, an evaluation must be completed that demonstrates that the SG performance criteria will continue to be met until the next refueling outage or SG tube inspection. The tube integrity determination is based on the estimated condition of the tube at the time the situation is discovered and the estimated growth of the degradation prior to the next SG tube inspection. If it is determined that tube integrity is not being maintained, Specification 2.23(3) applies.

A Completion Time of 7 days is sufficient to complete the evaluation while minimizing the risk of plant operation with a SG tube that may not have tube integrity.

If the evaluation determines that the affected tube(s) have tube integrity, Required Action 2.23(2)b allows plant operation to continue until the next refueling outage or SG inspection provided the inspection interval continues to be supported by an operational assessment that reflects the affected tubes. However, the affected tube(s) must be plugged prior to exceeding 210°F reactor coolant temperature (Tcold) following the next refueling outage or SG inspection. This Completion Time is acceptable since operation until the next inspection is supported by the operational assessment.

If the Required Actions and associated Completion Times of Technical Specification 2.23(2) are not met or if SG tube integrity is not being maintained, the reactor must be brought to MODE 3 within 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and MODE 4 within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months .

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

TECHNICAL SPECIFICATIONS 3.0 SURVEILLANCE REQUIREMENTS 3.2 Equipment and Sampling Tests (continued)

The Safety Injection (SI) pump room air treatment system consists of charcoal adsorbers which are installed in normally bypassed ducts. This system is designed to reduce the potential release of radioiodine in SI pump rooms during the recirculation period following a DBA. The in-place and laboratory testing of charcoal adsorbers will assure system integrity and performance.

Pressure drops across the combined HEPA filters and charcoal adsorbers, of less than 9 inches of water for the control room filters (VA-64A & VA-64B) and of less than 6 inches of water for each of the other air treatment systems will indicate that the filters and adsorbers are not clogged by amounts of foreign matter that would interfere with performance to established levels. Operation of each system for 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months every month will demonstrate operability and remove excessive moisture build-up in the adsorbers.

The hydrogen purge system provides the control of combustible gases (hydrogen) in containment for a post-LOCA environment. The surveillance tests provide assurance that the system is operable and capable of performing its design function. VA-80A or VA-80B is capable of controlling the expected hydrogen generation (67 SCFM) associated with 1) Zirconium - water reactions, 2) radiolytic decomposition of sump water and 3) corrosion of metals within containment. The system should have a minimum of one blower with associated valves and piping (VA-80A or VA-80B) available at all times to meet the guidelines of Regulatory Guide 1.7 (1971).

If significant painting, fire or chemical release occurs such that the HEPA filters or charcoal adsorbers could become contaminated from the fumes, chemicals or foreign materials, testing will be performed to confirm system performance.

Demonstration of the automatic and/or manual initiation capability will assure the system's availability.

Verifying Reactor Coolant System (RCS) leakage to be within the LCO limits ensures the integrity of the Reactor Coolant Pressure Boundary (RCPB) is maintained. Pressure boundary leakage would at first appear as unidentified leakage and can only be positively identified by inspection. Unidentified leakage is determined by performance of an RCS water inventory balance. Identified leakage is then determined by isolation and/or inspection. Since Primary to Secondary Leakage of 150 gallons per day cannot be measured accurately by an RCS water inventory balance, note .***" for line item 8a on Table 3-5 states that the Reactor Coolant System Leakage surveillance is not applicable to Primary to Secondary Leakage.

Primary to secondary leakage is measured by performance of effluent monitoring within the secondary steam and feedwater systems.

TECHNICAL SPECIFICATIONS 3.0 SURVEILLANCE REQUIREMENTS 3.2 Equipment and Sampling Tests (continued)

Table 3-5, Item 8b verifies that primary to secondary LEAKAGE is less or equal to 150 gallons per day through any one SG. Satisfying the primary to secondary LEAKAGE limit ensures that the operational LEAKAGE performance criterion in the Steam Generator Program is met. If this surveillance requirement is not met, compliance with LCO 3.17, "Steam Generator Tube Integrity," should be evaluated. The 150 gallons per day limit is measured at room temperature as described in Reference 5. The operational LEAKAGE rate limit applies to LEAKAGE through any one SG. If it is not practical to assign the LEAKAGE to an individual SG, all the primary to secondary LEAKAGE should be conservatively assumed to be from one SG.

The Surveillance is modified by a Note which states that the Surveillance is not required to be performed until 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months after establishment of steady state operation. For RCS primary to secondary LEAKAGE determination, steady state is defined as stable RCS pressure, temperature, power level, pressurizer and makeup tank levels, makeup and letdown, and RCP seal injection and return flows.

The Surveillance Frequency of daily is a reasonable interval to trend primary to secondary LEAKAGE and recognizes the importance of early leakage detection in the prevention of accidents. The primary to secondary LEAKAGE is determined using continuous process radiation monitors or radiochemical grab sampling in accordance with the EPRI guidelines (Ref. 5).

3.17 - Page 1 Amendment No. 404-,495

TECHNICAL SPECIFICATIONS 3.0 SURVEILLANCE REQUIREMENTS 3.17 Steam Generator Tubes (Continued)

Basis During shutdown periods the SGs are inspected as required by this Surveillance Requirement (SR) and the Steam Generator Program. NEI 97-06, Steam Generator Program Guidelines (Ref. 1), and its referenced EPRI Guidelines, establish the content of the Steam Generator Program. Use of the Steam Generator Program ensures that the inspection is appropriate and consistent with accepted industry practices.

During SG inspections a condition monitoring assessment of the SG tubes is performed. The condition monitoring assessment determines the "as found" condition of the SG tubes. The purpose of the condition monitoring assessment is to ensure that the SG performance criteria have been met for the previous operating period.

The Steam Generator Program determines the scope of the inspection and the methods used to determine whether the tubes contain flaws satisfying the tube repair criteria. Inspection scope (i.e., which tubes or areas of tubing within the SG are to be inspected) is a function of existing and potential degradation locations. The Steam Generator Program also specifies the inspection methods to be used to find potential degradation. Inspection methods are a function of degradation morphology, non-destructive examination (NDE) technique capabilities, and inspection locations.

The Steam Generator Program defines the Frequency of SR 3.17(1). The Frequency is determined by the operational assessment and other limits in the SG examination guidelines (Ref. 6). The Steam Generator Program uses information on existing degradations and growth rates to determine an inspection Frequency that provides reasonable assurance that the tubing will meet the SG performance criteria at the next scheduled inspection. In addition, Specification 5.23 contains prescriptive requirements concerning inspection intervals to provide added assurance that the SG performance criteria will be met between scheduled inspections.

During an SG inspection, any inspected tube that satisfies the Steam Generator Program repair criteria is removed from service by plugging. The tube repair criteria delineated in Specification 5.23 are intended to ensure that tubes accepted for continued service satisfy the SG performance criteria with allowance for error in the flaw size measurement and for future flaw growth. In addition, the tube repair criteria, in conjunction with other elements of the Steam Generator Program, ensure that the SG performance criteria will continue to be met until the next inspection of the subject tube(s). Reference 1 provides guidance for performing operational assessments to verify that the tubes remaining in service will continue to meet the SG performance criteria.

The Frequency of prior to exceeding 21 0°F reactor coolant temperature (Tcod) following a SG inspection ensures that the Surveillance has been completed and all tubes meeting the repair criteria are plugged prior to subjecting the SG tubes to significant primary to secondary pressure differential.

TECHNICAL SPECIFICATIONS 5.0 ADMINISTRATIVE CONTROLS 5.23 Steam Generator (SG) Program A Steam Generator Program shall be established and implemented to ensure that SG tube integrity is maintained. In addition, the Steam Generator Program shall include the following provisions:

a. Provisions for condition monitoring assessments. Condition monitoring assessment means an evaluation of the "as found" condition of the tubing with respect to the performance criteria for structural integrity and accident induced leakage. The "as found" condition refers to the condition of the tubing during an SG inspection outage, as determined from the inservice inspection results or by other means, prior to the plugging of tubes. Condition monitoring assessments shall be conducted during each outage during which the SG tubes are inspected or plugged to confirm that the performance criteria are being met.

b. Performance criteria for SG tube integrity. SG tube integrity shall be maintained by meeting the performance criteria for tube structural integrity, accident induced leakage, and operational LEAKAGE.

1. Structural integrity performance criterion: All in-service steam generator tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power range, hot standby, and cool down and all anticipated transients included in the design specification) and design basis accidents. This includes retaining a safety factor of 3.0 against burst under normal steady state full power operation primary-to-secondary pressure differential and a safety factor of 1.4 against burst applied to the design basis accident primary-to-secondary pressure differentials. Apart from the above requirements, additional loading conditions associated with the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine ifthe associated loads contribute significantly to burst or collapse. In the assessment of tube integrity, those loads that do significantly affect burst or collapse shall be determined and assessed in combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondary loads.

2. Accident induced leakage performance criterion: The primary to secondary accident induced leakage rate for any design basis accident, other than a SG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of total leakage rate for all SGs and leakage rate for an individual SG. Leakage is not to exceed 1 gpm per SG.

3. The operational LEAKAGE performance criterion is specified in LCO 2.1.4, "Reactor Coolant System Leakage Limits."

c. Provisions for SG tube repair criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal tube wall thickness shall be plugged.

5.0 - Page 19 Amendment No.

TECHNICAL SPECIFICATIONS 5.0 ADMINISTRATIVE CONTROLS 5.23 Steam Generator (SG) Program (continued)

d. Provisions for SG tube inspections. Periodic SG tube inspections shall be performed. The number and portions of the tubes inspected and methods of inspection shall be performed with the objective of detecting flaws of any type (e.g., volumetric flaws, axial and circumferential cracks) that may be present along the length of the tube, from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicable tube repair criteria. The tube-to-tubesheet weld is not part of the tube. In addition to meeting the requirements of d.1, d.2, and d.3 below, the inspection scope, inspection methods, and inspection intervals shall be such as to ensure that SG tube integrity is maintained until the next SG inspection. An assessment of degradation shall be performed to determine the type and location of flaws to which the tubes may be susceptible and, based on this assessment, to determine which inspection methods need to be employed and at what locations.

1. Inspect 100% of the tubes in each SG during the first refueling outage following SG replacement.

2. Inspect 100% of the tubes at sequential periods of 144, 108, 72, and, thereafter, 60 effective full power months. The first sequential period shall be considered to begin after the first inservice inspection of the SGs. In addition, inspect 50% of the tubes by the refueling outage nearest the midpoint of the period and the remaining 50% by the refueling outage nearest the end of the period. No SG shall operate for more than 72 effective full power months or three refueling outages (whichever is less) without being inspected.

3. If crack indications are found in any SG tube, then the next inspection for each SG for the degradation mechanism that caused the crack indication shall not exceed 24 effective full power months or one refueling outage (whichever is less). If definitive information, such as from examination of a pulled tube, diagnostic non-destructive testing, or engineering evaluation indicates that a crack-like indication is not associated with a crack(s), then the indication need not be treated as a crack.

e. Provisions for monitoring operational primary to secondary LEAKAGE.

LIC-06-0087 Page 1 ATTACHMENT 5 Responses to Requests for Additional Information Related to the May 30, 2006 TSTF-449 Submittal

LIC-06-0087 Page 2 Responses to Requests for Additional Information Related to the May 30, 2006 TSTF-449 Submittal NRC Request #1 In Technical Specification (TS) 2.1.1(6), you proposed that "each steam generator shall be demonstrated operable by the performance of the requirements specified in Section 3.17 prior to exceeding a reactor coolant temperature of 300 0 F."

In addition, you indicate that steam generator operability can be achieved by verifying tube integrity in accordance with the Steam Generator Program and by verifying that each inspected tube that satisfies the tube repair criteria is plugged prior to exceeding a cold leg temperature of 210 0F. As currently written, steam generator operability can be demonstrated by simply performing the surveillance requirement.

TSTF-449 expanded the definition of steam generator operability by deleting the phrase that operability is in accordance with the steam generator tube surveillance program. Please discuss your plans for making your proposal consistent with TSTF-449 (in TS 2.1.1 and TS 3.17).

In addition, given the unique structure of your TS, please clarify why TS 2.1.1(6) is still needed in light of the proposed addition of TS 2.23 which will establish new limiting conditions for operation for the steam generators.

OPPDResponse:

The sentence in TS 2.1.1(6), concerning demonstrating that each SG is operable by performance of an inservice inspection program, is duplicate information to TS 2.23, which specifies the requirements for steam generatortube integrity as part of the reactorcoolant pressure boundary in more detail,and will be deleted.

NRC Request #2 There are inconsistencies between the temperature in TS 2.1.1(6) (temperature of 300 0F), TS 3.17(2)

(cold-leg temperature of 210 0F), and TSTF-449 (average coolant temperature of 200 0 F). In addition, there are no limits on the reactivity condition in your proposed TS requirements; unlike TSTF-449.

Please discuss your plans for modifying your proposal to make it consistent with TSTF-449.

OPPD Response:

The Tc*Id 210OF requirementis used in other technicalspecifications. TS 2.1.1(6) will be deleted in response to question 1.

NRC Request #3 It would appear that the title for entry 8b in Table 3-5 would more appropriately be "primary- to-secondary leakage" rather than steam generator tube integrity. Please discuss why steam generator tube integrity was chosen rather than primary-to-secondary leakage. Alternatively, modify your proposal to indicate primary-to-secondary leakage for item 8b. The staff notes that the leakage limit will not ensure steam generator tube integrity.

LIC-06-0087 Attachment 5 Page 3 OPPDResponse:

The table entry will be revised to labeled primary-to-secondaryleakage per the Staff request.

NRC Request #4 In Table 3-5, the frequency is labeled as "D." Please discuss where "D" is defined within the specification. Alternatively, discuss your plans for specifying that the frequency is "daily."

OPPDResponse:

TS 3.0.2 defines the letter designations.

NRC Request #5 In Table 3-5, the "Test" for "primary to secondary leakage" is listed as "evaluate". The meaning of this term is not clear. Isn't the "Test" for primary to secondary leakage, continuous monitoring of the effluent (steam and feedwater systems) for radioactive isotopes or performing radiochemical analyses of grab samples of the steam and feedwater systems? Similarly, isn't the "Test" for reactor coolant system leakage, a water inventory balance? Please clarify.

OPPDResponse:

The technical basis is provided in the last paragraphof TS 3.2: "The primary to secondary LEAKAGE is determined using the continuous process radiationmonitors or radiochemicalgrab sampling in accordancewith the EPRI guidelines." The table 3.5 test will be modified to change "evaluate" by replacing it with "Continuous process radiation monitors or radiochemical grab sampling".

NRC Request #6 In the second paragraph on page 5 of TS 3.2, it would appear that the reference to the limiting condition for operation should be TS 2.23 rather than TS 3.17 since TS 3.17 are the surveillance requirements.

Please discuss your plans for modifying this reference.

OPPDResponse:

OPPD agrees and Page 5 of TS 3.2, will be modified to reference the limiting condition for operationTS 2.23.

NRC Request #7 Proposed TS 2.23(2)(b) indicates that a tube should be plugged prior to entering Mode 4 following the next refueling outage or SG tube inspection. Given that Mode 4 is Cold Shutdown at your plant, this would require you to be in a refueling outage (i.e., prior to entering Mode 4). To be more consistent with the applicability section of TS 2.23 and TSTF-449, would it be more appropriate to indicate that the tube(s) should be plugged "prior to exiting Mode 4." Please discuss. If this specification is changed, the bases on 2.23-Page 4 will also need to be modified.

LIC-06-0087 Page 4 OPPD Response:

OPPD agrees and Page 5 of TS 2.23(b) including the bases on 2.23-Page 4 will be modified to indicate that the tube(s) should be plugged prior to a cold-leg temperature of 210'F. This change is also consistent with the statement in the lastparagraphin the TS 3.17 basis.

NRC Request #8 In proposed TS 2.23, it would appear that TS 2.23(2) would permit you to elect not to plug a tube provided the conditions in TS 2.23(2)(a) and TS 2.23(2)(b) were met. This is not consistent with TSTF-449. In TSTF-449, the required actions are intended to apply only in the event a tube was inadvertently identified as not being plugged rather than electing not to plug a tube. TS 2.23 should be worded such that the plugging of SG tubes that meet the repair criteria cannot be interpreted as an elective action.

Suggested wording for TS 2.23(2) that is also consistent with TS 2.1.4 would be, "Ifthe requirements of (1)(b) above are not met for one or more SG tubes, then perform the following." Please discuss your plans to clarify your technical specifications in this regard. In addition, discuss your plans to clearly indicate that "separate condition entry" is only allowed for TS 2.23(2).

OPPDResponse:

OPPD agrees and TS 2.23(2) will be reworded to: "ifthe requirements of (1)(b) above are not met for one or more SG tubes, then perform the following."

NRC Request #9 In your Basis for TS 2.23, you indicate that "large differential pressures across SG tubes can only be experienced in MODE 1, 2, or 3". It is not clear that this is a true statement for your facility since MODE 3 is when the average temperature is greater than 515 0F and MODE 4 is when the cold-leg temperature is less than 210°F. It would appear that large differential pressures could occur when the temperature is 510°F (which is before MODE 4). Please discuss whether large differential pressures could occur when the reactor coolant temperatures are "between" those defined in MODES 3 and 4. If so, discuss your plans to modify your basis.

OPPDResponse:

OPPD agrees and Bases for TS 2.23(2) will be reworded to indicate that large differential pressuresacross SG tubes can only be experienced when the Tcold is > 210°F.

NRC Request #10 TS 3.17(1) indicates that tube integrity will be verified "at a frequency defined by the Steam Generator Program." The phrase "at a frequency defined by the Steam Generator Program" is not included in TSTF-449. The frequency specified in the Steam Generator Program (TS 5.23) is a maximum inspection interval and the actual intervals may need to be less to ensure tube integrity is maintained. Please discuss your plans to remove this phrase from your proposal (to avoid the possibility that this phrase could be referring to the maximum interval specified in TS 5.23).

OPPDResponse:

OPPDagrees to truncate the sentence to delete the phrase to match the TSTF-449.

LIC-06-0087 Page 5 NRC Request #11 TS 3.17(3) and TS 3.17(4) are "not used." Please discuss why proposed TS 3.17(5) was not included as TS 3.17(3) and why TS 3.17(4) was not deleted.

OPPDResponse:

This change will be made.

NRC Request #12 In the last sentence of TS 5.23a, there appears to be a typographical error. The sentence should read,

"...tubes are inspected or plugged to confirm .....".

OPPD Response:

This change will be made.

NRC Request #13 In TS 5.23.b.3, TS 2.1.4 is referred to as "Reactor Coolant System Operational Leakage.". The actual title is "Reactor Coolant System Leakage Limits." Please discuss your plans for correcting this typographical error. The staff notes that the correct title is used in TS 2.23 - page 3 (although without the opening quote marks).

OPPDResponse:

This change will be made.

NRC Request #14 In TS 5.23.d.2, the parentheses ("]") at the end of the sentence should be deleted. Please discuss your plans to correct this apparent typographical error.

OPPD Response:

This change will be made.
