==1.0         DESCRIPTION==

Pursuant to 10 CFR 50.90, Luminant Generation Company, LLC (Luminant Power) hereby requests an amendment to the Comanche Peak Nuclear Power Plant (CPNPP) Unit 1 and Unit 2 Technical Specifications. The proposed change revises Technical Specifications (TS) 3.4.17, "Steam Generator (SG) Tube Integrity," TS 5.5.9, "Unit 1 Model D76 and Unit 2 Model D5 Steam Generator (SG) Program", and TS 5.6.9, "Unit 1 Model D76 and Unit 2 Model D5 Steam Generator Tube Inspection Report." The proposed changes are needed to address implementation issues associated with inspection periods, and address other administrative changes and clarifications.
The proposed amendment is consistent with T3T1-510, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection."
Approval of this amendment application is requested by January 10, 2014, to support CPNPP Unit 2 Refueling Outage 14 (Spring 2014).
2.0         ASSESSMEN 2.1 Applicability of Publishwd Safety Evaluadton Luminant Generation Company LLC (Luminant Power) has reviewed 1TM-510, Revision 2, "Revision to Steam Generator Program Inspection Fmeuencies and Tube Sample Selection.,"
(ADANS Accession No. ML110610=50) and the Model Safety Evaluation dated October 19,2011 (ADAMS Aocesson No. ML112101513) as identifled'in the Federal Register Notice of Availability, dated October 27, 2011 (76 FR 66763). As described in the subsequent paragraphs, Luminant Power has concluded that the justifications presented in IMF-510 and the Model Safety Evaluation prepared by the Nuclear Regulatory Commission (NRC) staff is applicable to CPNPP Units 1 and 2 and justify this amendment for fnoporation of the changes to the CPNPP 1S.
2.2 Optona Changes and Varition Luminant-Power is proposinS the following variations from the 13 changes described in T1T1 510, Revision 2, or the applicable parts of the NRC staffs model safety evaluation dated October 27,2011.
The CPNPP TS utilize different numbering and titles than the Standard Technical Spedfications on which TSTF-510 was basecl. Specifically, the CPNPP 1S title for Section 5,5.9 is "Unit I Model D76 and Unit 2 Model D5 Steam Generator (SG) Program," to denote that the CPNPP SGs are different models. 1       ,-51071SSection 5.5.94.d2for uispbctom after the flint refueling outage following SG Installation has been divided in the CPNPP TS as Section 5.5.9.d.2 for the CPNPP Unit 2 model D5 steam generators and Section 5.5.9.d3 for the CPNPP Unit I model Delta-76 steam generators. TSTF-510 13 Section 5.5.9.d3 is CPNPP TS Section 5.5.9.d4A for crack indications. These difference are administrative and do not affect the applicability of TSM.-510 to the CPNPP 7S.
The proposed change corrects an ade                  inconsistency in 171W-510, Paragraph d.2 of the Steam Generator Tube Inpection Program. In Section 2.0, "Proposing Change," 1311-510 states that references to "tube repair criteria" in Paragraph d is revised to "tube plugging [or repair] criteria." However, in the following sentence in Paragraph d2, this change was to TXX-13097 Page 3 of 4 07/10/2013 inadvertently omitted, "If a degradation assessment indicates the potential for a type of degradation to occur at a location not previously inspected with a technique capable of detecting this type of degradation at the location and that may satisfy the applicable tube repair criteria the minimum number of locations inspected with such a capable inspection technique during the remainder of the inspection period may be prorated" (Emphasis added).
Luminant Power does have an approved tube repair criteria. Therefore the sentence is revised to state "tube plugging [or repair] criteria.

==3.0         REGULATORY ANALYSIS==

3.1      No Significant Hazards Consideration Determination Luminant Power requests adoption of an approved change to the standard technical specifications (STS) into the plant specific Technical Specifications (19) for CPNPP, Units 1 and 2, to revise TS 3A.17, "Steam Generator (SG) Tube Integrity," 75 5.5.9, "Unit 1 Model 1D76 and Unit 2 Model D5 Steam Generator (GP Program", and 7S 5.6.9, "Unit 1 Model 1D76 and Unit 2 Model D5 Steam Generator Tube Inspection Report" to address inspection periods and other administrative changes and clarifications.
As required by 10 CFR 50.91(a), an analysis of the Issue of no significant hazards consideration is presented below:
L.       Does the proposed change involve a significant increase In the probability or consequences of an accident previously evaluated?
Response: No The proposed change revises the Steam Generator (SG) Program to modify the frequency of verification of SG tube integty and SC tube sample selection. A steam generator tube rupture (SG1) event is one of the design basis accidents that are analyzed as part of a plant's licensing basis. The proposed SC tube Inspection frequency and sample selection criteria will continue to ensure that the SG tubes are inspected such that the probability of a SGTRis not increased. The consequences of a SGTR are bounded by the conservative assumptions In the design basis accident analysis. The proposed change will not cause the consequences of'a SGTh to exceed those assumptions.
Therefore, it is concluded that the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
Z         Does the proposed change cueate the possibility of a new or dierent MId of accident frm any accident previously evaluated?
Response- No The proposed changes to the Steam Generator Program will not introduce any adverse changes to the plant design basis or postulated accidents resulting from potential tube degradation. The proposed change does not affect the design of the SGs or their method of operation. In addition, the proposed change does not impact any other plant system or component.
to TXX-13097 Page 4 of 4 07/10/2013 Therefore, the proposed change does not create the possibility of a new or different type of accident from any accident previously evaluated.
: 3.        Does the proposed change involve a significant reduction in a margin of safety?
Response: No The SG tubes in pressurized water reactors are an integral part of the reactor coolant pressure boundary and, as such, are relied upon to maintain the primary system's pressure and inventory. As part of the reactor coolant pressure boundary, the SG tubes are unique in that they are also relied upon as a heat transfer surface between the primary and secondary systems such that residual heat can be removed from the primary system. In addition, the SC tubes also isolate the radioactive fission products In the primary coolant from the secondary system. In summary, the safety function of a SG Is maintained by ensuring the integrity of its tubes. Steam generator tube integrity is a function of the design, environment, and the physical condition of the tube. The proposed change does not affect tube design or operating environment. The proposed change will continue to require monitoring of the physical condition of the SC tubes such that there will not be a reduction In the margin of safety compared to the current Therefore, it is concluded that the proposed change does not involve a significant reduction in a margin of safety.
Based on the above evaluations, Luminant Power concludes that the proposed amendment presents no significant hazards under the standards set forth in 10 CFR 50.92(c) and, accordingly, a finding of "no significant hazards consideration" is justified.
4.0           NIONOMMN                ON The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted areas, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CR 51M2(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

In addition, the Steam Generator Program shall include the following:
: 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 criterla for SO 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-servile 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), all anticipated transients Included Inthe design specification, anddesign basis accidents. This Includes retaining a safety factor of 3.0 against burnt under normal steady state full power operation primary-to-secondary pressure differential and a safety factor of 14 against burst applied to the design basis accident primay4o-c              pressure diffrentlis, Apart from the above requirements, additional loading conditions associated with thedesign 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 signifkcantyaffect 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 ccident, other than a SGtube rupture, shall not exceed the leakage rate assumed In the accident analysis in terms of total leakage rate for all SQs and leakage rate for an individualG  SG. Leakage i not to      -
exceed I gpm per SG.

For Unit 1, 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., volumetr flaws, axial and circumferential cracks) that may be present along the length of the tube, from the tube-to0tubesheet weld at the tube Inlet to the tube-to-tubesheet weld at the tube outlet, and that may satisfy the applicable tube plugging [or repairi criteria. For Unit 2, the number and portions of the tubes Inspected and methods of Inspection shll 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 14.01 Inches below the top of the tubesheet on the hot leg side to 14.01 Inches below the top of the tubesheet on the cold leg side 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 below, the Inspection scope, Inspection methods and Inspection Intervals shall be such as to ensure that SO tube Integrity Is maintained until the next SQ Inspection. A degradation assessment 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.,

SG Tube Integrity B 3.4.17 BASES (continued)
APPLICABLE        The steam generator tube rupture (SGTR) accident is the limiting design SAFETY ANALYSES   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 LCO 3.4.13, "RCS Operational LEAKAGE," plus the leakage rate associated with a double-ended rupture of a single tube. The accident analysis for a SGTR assumes the contaminated secondary fluid is only briefly released to the atmosphere via safety valves and the majority is discharged to the main condenser. However, the radiological dose consequence analysis for SGTR assumes the condenser is not available, and that the Atmospheric Relief Valve on the affected (ruptured) SG opens following the reactor trip / turbine trip and fails to close, thereby releasing the radioactivity directly to the atmosphere.
The analysis for design basis accidents and transients other than a SGTR assume the SO tubes retain their structural Integrity (i.e., they are assumed not to rupture.) Inthese 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 I assumed to increase to I 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 LCO 3.4.16, "RCS Specific Activity," 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 Omits 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 Integrilty satisfies Criteron 2 of 10 CFR 50.36(cX2)(li).
LCO               The LCO requires that SO tube integrity be maintained. The LCO also requires that all SG tubes that satisfy the p ggirg q       r repair] criteria be plugged (or repaired for Unit 1 D4 SGs only) In accordance with the Steam Generator Program.
During an SO Inspection, any inspected tube that satisfes the Steam Generator Program p1ugg ng tor repair] criteria Is repaired (Unit I D4 SGs only) or removed from service by plugging. If a tube was determined to satisfy the phuggir:      repal criteria but was not plugged (or repaired for Unit 1 D4 SGs only), the tube may still have tube Integrity.
in the context of this Specification, a SO tube is defined as the entire length of the tube, including the tube wall and any repairs made to It, between the tube-to-tubesheet weld at the tube Inlet and the tube-to-tubesheet weld at (continued)

SG Tube Integrity B 3.4.17 BASES LCO (continued)
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 1 gpm per SG, except for specific types of degradation at specific locations where the NRC has approved greater accident induced leakage (i.e., Specification 5.5.9.1; "Unit I model D4 Steam Generator (SG) Program"). 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 LCO 3.4.13, "RCS Operational LEAKAGE," 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.
APPLICABILITY    Steam generator tube Integrity is challenged when the pressure diffMerential across the tubes Is large. Large differential pressures across SG tubes can only be experienced in MODE 1, 2, 3, or 4.
RCS conditions are far less challenging In MODES 5 and 6 than during MODES 1, 2, 3, and 4. In MODES 5 and 6, primary to secondary differential pressure is low, resulting In lower stresses and reduced potential for LEAKAGE.
ACTIONS          The ACTIONS are modified by a Note clarifying that the Conditions may be entered Independently for each SG tube. This Is acceptable because the RequWred Actions provilde appropriate compensatory actions for each affected SG tube. Complying with the Required Actions may allow for continued operation, and subsequent affected SG tubes are govemed by subsequent Condition entry and application of associated Required Actions.
A.1 and A.2 Condition A applles if It Is discovered th# one or more SG tubes examined in an Inservice inspection satisfy the tube plu-,ging tcr repai criteria but were   I not plugged (or repaired for Unit 10 4 SGs only) In accordance with the Steam Generator Program as required by SR 3.4.17.2.

SG Tube Integrity B 3.4.17 BASES ACTIONS          A.1 and A.2 (continued) 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. The SG plugging [or 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 ifa SG tube that should have been plugged (or repaired for Unit 1 D4 SGs only) 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, Condition B 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 A.2 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 effected tube(s) must be plugged (or repaired for Unit I D4 SGs only) prior to entering MODE 4 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.
8.1 and 5.2 If the Required Actions and aswciatd Completlon Tines of Condition A are not met or IfSG tube IntegrityIs not bein mantained, the reactor must be brought to MODE 3 wthIn 6 hors and MODE 6 within 36 hours. The allowed Compltion Times are reasonable, based on operating experience, to reach the desired plant conditions from full power conditios in an orderly manner and without challenging plant systems.

REQUIREMENTS 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 plugging [or 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 te 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 3.4.17.1. 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 perfornance crtei at the next scheduled inspection. In addition, Specification 5.5.9 contains prescriptive requirements concerning Inspection Intervals to provide added assurance that the SG performance criteria will be met between scheduled Inspections. f ck indinns are found in any SG tube, tfe ma~xim mi sp~ec*-n intervd for a: affected arid pvtentia~y affecte    SGs is rectrieJ by Spcfcation 5.5.9 unti! subsequent insp-et~on support extending the *inse#ton interia[

SG Tube Integrity B 3.4.17 BASES (continued)
APPLICABLE        The steam generator tube rupture (SGTR) accident is the limiting design SAFETY ANALYSES   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 LCO 3.4.13, "RCS Operational LEAKAGE," plus the leakage rate associated with a double-ended rupture of a single tube. The accident analysis for a SGTR assumes the contaminated secondary fluid is only briefly released to the atmosphere via safety valves and the majority is discharged to the main condenser. However, the radiological dose consequence analysis for SGTR assumes the condenser is not available, and that the Atmospheric Relief Valve on the affected (ruptured) SG opens following the reactor trip / turbine trip and fails to close, thereby releasing the radioactivity directly to the atmosphere.
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 LCO 3.4.16, "RCS Specific Activity," 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)(2Xii).
LCO               The LCO requires that SG tube Integrity be maintained. The LCO also requires that all SG tubes that satisfy the plugging [or repaird criteria be        I plugged (or repaired for Unit 1 D4 SGs only) in accordance with the Steam Generator Program.
During an SG inspection, any Inspected tube that satisfies the Steam Generator Program plugging [or repair] criteria is repaired (Unit I D4 SGs only) or removed from service by plugging. Ifa tube was determined to satisfy the plugging [or repair] criteria but was not plugged (or repaired for      I Unit 1 D4 SGs only), 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 and any repairs made to it, between the tube-to-tubesheet weld at the tube Inlet and the tube-to-tubesheet weld at (continued)

SG Tube Integrity B 3.4.17 BASES LCO (continued)
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 1 gpm per SG, except for specific types of degradation at specific locations where the NRC has approved greater accident induced leakage (i.e., Specification 5.5.9.1; "Unit 1 model D4 Steam Generator (SG) Program"). 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 LCO 3.4.13, "RCS Operational LEAKAGE," 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.
APPLICABILITY    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 In MODE 1, 2, 3, or 4.
RCS conditions are far less challenging in MODES 5 and 6 than during MODES 1, 2, 3, and 4. In MODES 5 and 6, primary to secondary differential pressure is low, resulting in lower stresses and reduced potential for LEAKAGE.
ACTIONS          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.
A.1 and A.2 Condition A appiles IfitIs discovered that one or more SG tubes examined In an Inservice inspection satisfy the tube plugging [or repair] criteria but were   I not plugged (or repaired for Unit 1 )4 SGs only) in accordance with the Steam Generator Program as required by SR 3.4.17.2. An evaluation of SG (continued)

SG Tube Integrity B 3.4.17 BASES ACTIONS          A.1 and A.2 (continued) 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. The SG plugging [or 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 ifa SG tube that should have been plugged (or repaired for Unit 1 D4 SGs only) 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, Condition B 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 A.2 allows plant operation to continue until the next refueling outage or SG inspection pmrvided the Inspection Interval continues to be supported by an operational assessment that reflects the affected tubes. However, the affected tube(s) must be plugged (or repaired for Unit I D4 SGs only) prior to entering MODE 4 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.
8.1 and B.2 If the Required Actions and associated Completion Times of Condition A are not met or If SG tube Integrity is not being maintained, the reactor must be brought to MODE 3 within 6 hours and MODE 5 within 36 hours. The allowed Completloh 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.

REQUIREMENTS 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 plugging [or repair] criteria. Inspection scope (i.e., which tubes or areas of tubing within the SO 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 3.4.17.1. The Frequency Is determined by the operational assessment and other limits In the SO 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 wll meet the SO performance criteria at the next scheduled inspection. In addition, Specification 5.5.9 contains prescriptive requirements concerning Inspection Intervals to provide added assurance that the SO performance criteria wiHl be met between scheduled Inspections. if crack indications are found In any SO tube, the maximum Inspection Interval for all affected and potentially affected SG. is restricted by Specification 5.5.9 until subsequent inspections support extending the inspection interval.
SR 3.4.17.2 During an SO Inspection, any inspected tube that satisfies the Steam Generator Program plugging [or repair] criteria is repaired (Unit 1 D4 SGs only) or removed from service by plugging. The tube plugging [or repair]
