1.0 DESCRIPTION

Constellation Energy Generation, LLC (CEG) requests adoption of TSTF-577, "Revised Frequencies for Steam Generator Tube Inspections," which is an approved change to the Standard Technical Specifications (STS), into the Technical Specifications (TS) for Braidwood Station, Units 1 and 2 (Braidwood); Byron Station, Units 1 and 2 (Byron); Calvert Cliffs Nuclear Power Plant, Units 1 and 2 (Calvert Cliffs); and R.E. Ginna Nuclear Power Plant (Ginna). The TS related to steam generator (SG) tube inspections and reporting are revised based on operating history.

2.0 ASSESSMENT 2.1 Applicability of Safety Evaluation CEG has reviewed the safety evaluation for TSTF-577 provided to the Technical Specifications Task Force in a letter dated April 14, 2021. This review included a review of the NRC staff's evaluation, as well as the information provided in TSTF-577. CEG has concluded that the justifications presented in TSTF-577 and the safety evaluation prepared by the NRC staff are applicable to Braidwood, Byron, Calvert Cliffs, and Ginna and justify this amendment for the incorporation of the changes to the Braidwood, Byron, Calvert Cliffs, and Ginna TS.

The current SG TS requirements for Braidwood, Byron, and Calvert Cliffs are based on TSTF-510, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection." The current SG TS requirements for Ginna are based on TSTF-449, "Steam Generator Tube Integrity." Braidwood, Byron, and Calvert Cliffs all have two units, while Ginna is a single unit site. The SGs for Braidwood Unit 1, Byron Unit 1, Ginna, and Calvert Cliffs, Units 1 and 2, have Alloy 690 thermally treated (Alloy 690TT) tubes. The SGs for Braidwood Unit 2 and Byron Unit 2 have Alloy 600 thermally treated (Alloy 600TT) tubes.

The initial inspection period described in the SG Program, paragraph d.2, began March 11, 2020, for Byron, Unit 1, and the initial inspection period described in the SG Program, paragraph d.3, began April 18, 2022, for Byron, Unit 2. CEG will submit SG Tube Inspection Reports meeting the revised TS 5.6.9 requirements within 30 days after implementation of the license amendment at Byron.

Once the amendments for Braidwood, Units 1 and 2, Calvert Cliffs, Units 1 and 2, and Ginna are approved, the TS will be implemented within 120 days. As use of the revised inspection period in TSTF-577 is contingent on the performance of a 100% inspection of all steam generator tubes in a single outage, new license conditions for Braidwood, Units 1 and 2, Calvert Cliffs, Units 1 and 2, and Ginna are provided in Attachments 4a through 4c, which will not permit the extended inspection interval of the TS Steam Generator Program following implementation until after performance of 100% inspection of all tubes in a single outage. CEG will submit SG Tube Inspection Reports within 180 days of performance of a 100% inspection of all steam generator tubes in a single outage for Braidwood, Units 1 and 2, Calvert Cliffs, Units 1 and 2, and Ginna in accordance with the requirements of TS 5.6.9, "Steam Generator Tube Inspection Report" [TS 5.6.7 for Ginna].

Page 1 of 6

Enclosure Description and Assessment CEG plans to inspect 100% of the SG tubes in Braidwood, Unit 1, during the fall 2022 refueling outage (A1R23) and 100% of the SG tubes in Braidwood, Unit 2, during the spring 2023 refueling outage (A2R23). CEG plans to inspect 100% of the SG tubes in Calvert Cliffs, Unit 1, during the spring 2026 refueling outage (CC1R28) and 100% of the SG tubes in Calvert Cliffs, Unit 2, during the spring 2025 refueling outage (CC2R26). CEG plans to inspect 100% of the SG tubes at Ginna during the spring 2023 refueling outage (G1R44). These inspections are required by current TS and will start the TSTF-577 period. At this time, CEG has no plans to defer these inspections.

2.2 Variations CEG is proposing the following variations from the TS changes described in TSTF-577 or the applicable parts of the NRC staff's safety evaluation dated April 14, 2021:

1) The CEG TS utilize different numbering than the Standard Technical Specifications on which TSTF-577 was based. Specifically, the numbering differences are as follows:

The "Steam Generator (SG) Tube Integrity" in the Ginna TS and Bases (Westinghouse STS) is numbered 3.4.17 rather than 3.4.20.

The "Steam Generator (SG) Program" in the Ginna TS (WOG TS) is numbered 5.5.8 rather than 5.5.9.

The "Steam Generator Tube Inspection Report" in the Braidwood and Byron (WOG TS) and Calvert Cliffs TS (CEOG TS) are numbered 5.6.9 rather than 5.6.7.

Due to Braidwood and Byron having common TS for Units 1 and 2 but two different tubing alloys, there are two "Item 2" items applicable from TSTF-577 under TS 5.5.9.d. Therefore, for the existing paragraph d.4 in the Braidwood and Byron TS 5.5.9 regarding crack indications, the newly added text for Braidwood Unit 2 and Byron Unit 2 is numbered "paragraph d.3" rather than "paragraph d.2."

These differences are administrative and do not affect the applicability of TSTF-577 to the Braidwood, Byron, Calvert Cliffs, and Ginna TS.

2) The Braidwood Unit 2 and Byron Unit 2 SG Program TS currently contains a provision for an alternate tube plugging criteria (TS 5.5.9.c). The descriptions of the alternate tube plugging criteria in the proposed change are equivalent to the descriptions in the current TS. Therefore, TSTF-577 is still applicable.

3) The Braidwood and Byron TS contain requirements that differ from the Standard Technical Specifications on which TSTF-577 was based but are encompassed in the TSTF-577 justification. Specifically, Braidwood TS 5.5.9.c and Byron TS 5.5.9.c currently state, in part: "The following alternate tube plugging criteria shall be applied as an alternative to the 40% depth based criteria:", where TSTF-577-A states: "The following alternate tube plugging [or repair] criteria may be applied as an alternative to the 40% depth based criteria:" (emphasis added).

Page 2 of 6

Enclosure Description and Assessment The alternate tube repair criteria sentence including the word "may" was added to TS 5.5.9.c of the WOG STS with TSTF-449-A, Revision 4, "Steam Generator Tube Integrity" (ADAMS Accession No. ML051090200). When Braidwood and Byron implemented TSTF-449-A with Amendment Nos. 144 and 150, respectively, issued March 30, 2007, the formatting of TSTF-449-A and the word "may" were not adopted.

The sentence, "The following alternate tube plugging criteria shall be applied as an alternative to the 40% depth based criteria:" (emphasis added) was added to Braidwood TS 5.5.9.c and Byron TS 5.5.9.c with Amendment Nos. 161 and 166, respectively, issued October 16, 2009 (ADAMS Accession No. ML09250512). The wording was not changed with later amendments.

The sentence for alternate tube plugging criteria (i.e., The following alternate tube plugging [or repair] criteria may be applied as an alternative to the 40% depth based criteria) remained in TS 5.5.9.c of the WOG STS with TSTF-510-A, Revision 0, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection" (ADAMS Accession No. ML090890367). Braidwood and Byron implemented TSTF-510-A with Amendment Nos. 172 and 179, respectively, issued March 21, 2013 (ADAMS Accession No. ML13009A182); however, the difference from the Standard Technical Specifications ("may" versus "shall") was not identified and updated at that time.

The word "shall" will be changed to "may" in Braidwood TS 5.5.9.c and Byron TS 5.5.9.c with this letter, which aligns with the wording in TSTF-577. Therefore, TSTF-577 is still applicable.

4) The Ginna TS contain requirements that differ from the Standard Technical Specifications on which TSTF-577 was based but are encompassed in prior Amendments. Specifically, Ginna TS 5.5.8.b.2 provides the following accident induced leakage 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 each SG" (emphasis added). This difference from TSTF-449, approved with Amendment No. 100 dated March 1, 2007 (ADAMS Accession No. ML070370623), is based on the plant-specific analysis. The Ginna TS will not be changed with the TSTF-577 proposed changes; therefore, TSTF-577 is still applicable.

5) The Braidwood and Byron TS contain requirements that differ from the Standard Technical Specifications on which TSTF-577 was based but are encompassed in prior Amendments. Specifically, for TS 5.5.9.b.2, the accident induced leakage performance criterion is more conservative for Braidwood and Byron (e.g., leakage is not to exceed a total of 1 gpm for all SGs), as approved with Amendment Nos. 144 and 150 dated March 30, 2007 (ADAMS Accession No. ML070810354). The current TS leakage values for Braidwood and Byron will not be changed with the TSTF-577 proposed changes; therefore, TSTF-577 is still applicable.

Enclosure Description and Assessment

6) The Braidwood, Byron, Calvert Cliffs, and Ginna TS contain requirements that differ from the Standard Technical Specifications on which TSTF-577 was based but are encompassed in the TSTF-577 justification. Specifically:

Braidwood and Byron TS 5.5.9.d currently reference d.1, d.2, and d.3. As referenced in item 1 above, Braidwood and Byron TS 5.5.9.d contain paragraph d.4 regarding crack indications. The markups for Braidwood and Byron TS 5.5.9.d have been modified to include paragraph d.4.

Calvert Cliffs TS 5.5.9.b currently reference "Steam generator" instead of "SG," and TS 5.6.9 currently does not include quotation marks around the program title, "Steam Generator (SG) Program." The markups for the Calvert Cliffs TS have been modified to correct these differences.

Ginna TS 5.5.8.b.1 currently states: "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." The markups for the Ginna TS have been modified to correct the placement of hyphens as shown in TSTF-577 as follows: "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." (emphasis added).

Ginna TS 5.5.8.d.2 currently states: ", with the exception that each SG is to be inspected during the fourth refueling outage in G1R44 following inspections completed in refueling outage G1R40." CEG plans to inspect 100% of the SG tubes during the spring 2023 refueling outage (G1R44) in support of the amendment implementation activities.

These differences from the Standard Technical Specifications are administrative and do not affect the applicability of TSTF-577 to the Braidwood, Byron, Calvert Cliffs, and Ginna TS.

3.0 REGULATORY ANALYSIS

3.1 No Significant Hazards Consideration Analysis Constellation Energy Generation, LLC (CEG) requests adoption of TSTF-577, "Revised Frequencies for Steam Generator Tube Inspections," which is an approved change to the Standard Technical Specifications (STS), into the Technical Specifications (TS) for Braidwood Station, Units 1 and 2 (Braidwood); Byron Station, Units 1 and 2 (Byron); Calvert Cliffs Nuclear Power Plant, Units 1 and 2 (Calvert Cliffs); and R.E. Ginna Nuclear Power Plant (Ginna). The TS related to steam generator (SG) tube inspections and reporting are revised based on operating history.

Page 4 of 6

Enclosure Description and Assessment CEG has evaluated if a significant hazards consideration is involved with the proposed amendments by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

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

Response: No The proposed change revises the inspection frequencies for SG tube inspections and associated reporting requirements. The SG inspections are conducted as part of the SG Program to ensure and demonstrate that performance criteria for tube structural integrity and accident leakage integrity are met. These performance criteria are consistent with the plant design and licensing basis. With the proposed changes to the inspection frequencies, the SG Program must still demonstrate that the performance criteria are met. As a result, the probability of any accident previously evaluated is not significantly increased and the consequences of any accident previously evaluated are not significantly increased.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

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

Response: No The proposed change revises the inspection frequencies for SG tube inspections and associated reporting requirements. The proposed change does not alter the design function or operation of the SGs or the ability of an SG to perform the design function.

The SG tubes continue to be required to meet the SG Program performance criteria.

The proposed change does not create the possibility of a new or different kind of accident due to credible new failure mechanisms, malfunctions, or accident initiators that are not considered in the design and licensing bases.

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

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

Response: No The proposed change revises the inspection frequencies for SG tube inspections and associated reporting requirements. The proposed change does not change any of the controlling values of parameters used to avoid exceeding regulatory or licensing limits.

The proposed change does not affect a design basis or safety limit, or any controlling value for a parameter established in the UFSAR or the license.

Page 5 of 6

Enclosure Description and Assessment Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above evaluation, CEG concludes that the proposed change 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.

3.2 Conclusion 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.

4.0 ENVIRONMENTAL CONSIDERATION

A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statements or environmental assessment need be prepared in connection with the proposed amendment.

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:

a. Provisions for condition monitoring assessments. Condition monitoring assessment means an evaluation of the "as found" SG 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.

SG

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), 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 if the 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.

BRAIDWOOD UNITS 1 & 2 5.5 7 Amendment 172

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program (continued)

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 a total of 1 gpm for all SGs.

3. The operational LEAKAGE performance criteria is specified in LCO 3.4.13, "RCS Operational LEAKAGE."

c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal wall thickness shall be plugged. The following alternate tube plugging criteria shall be applied as an alternative to the 40% depth based may criteria:

For Unit 2, tubes with service-induced flaws located greater than 14.01 inches below the top of the tubesheet do not require plugging. Tubes with service-induced flaws located in the portion of the tube from the top of the tubesheet to 14.01 inches below the top of the tubesheet shall be plugged upon detection.

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 plugging criteria. For Unit 2, portions of the tube below 14.01 inches from the top of the tubesheet are excluded from this requirement.

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. 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. 100% of the tubes in

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 this location and that may satisfy the applicable tube plugging criteria, the minimum number of locations inspected with such a capable inspection technique during the remainder of the inspection period may be prorated. The fraction of locations to be inspected for this potential type of degradation at this location at the end of the inspection period shall be no less than the ratio of the number of times the SG is scheduled to be inspected in the inspection period after the determination that a new form of degradation could potentially be occurring at this location divided by the total number of times the SG is scheduled to be inspected in the inspection period. Each inspection period defined below may be extended up to 3 effective full power months to include a SG inspection outage in an inspection period and the subsequent inspection period begins at the conclusion of the included SG inspection outage.

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:

a. Provisions for condition monitoring assessments. Condition monitoring assessment means an evaluation of the "as found" SG 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.

SG

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), 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 if the 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.

BYRON UNITS 1 & 2 5.5 7 Amendment 179

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program (continued)

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 a total of 1 gpm for all SGs.

3. The operational LEAKAGE performance criteria is specified in LCO 3.4.13, "RCS Operational LEAKAGE."

c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal wall thickness shall be plugged. The following alternate tube plugging criteria shall be applied as an alternative to the 40% depth based may criteria:

For Unit 2, tubes with service-induced flaws located greater than 14.01 inches below the top of the tubesheet do not require plugging. Tubes with service-induced flaws located in the portion of the tube from the top of the tubesheet to 14.01 inches below the top of the tubesheet shall be plugged upon detection.

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 plugging criteria. For Unit 2, portions of the tube below 14.01 inches from the top of the tubesheet are excluded from this requirement.

Programs and Manuals 5.5 SG 5.5.8 n Steam Generator (SG) Program SG 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. SG

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

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 steady state and a safety factor of 1.4 against burst applied to the design primary-to-secondary 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 if the 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 each SG. Leakage is not to exceed 1 gpm per SG.

c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal wall thickness shall be plugged. The following alternate tube plugging criteria may be applied as an alternative to the 40% depth based criteria:

For Unit 2, tubes with service-induced flaws located greater than 14.01 inches below the top of the tubesheet do not require plugging. Tubes with service-induced flaws located in the portion of the tube from the top of the tubesheet to 14.01 inches below the top of the tubesheet shall be plugged upon detection.

d. Provisions for SG tube inspections. Periodic SG tube inspections shall be performed.

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program An SG Program shall be established and implemented to ensure that SG tube integrity is maintained. In addition, the SG 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 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 SG 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 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 if the 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.

BYRON UNITS 1 & 2 5.5 7 Amendment

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program (continued)

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 a total of 1 gpm for all SGs.

3. The operational LEAKAGE performance criteria is specified in LCO 3.4.13, "RCS Operational LEAKAGE."

c. Provisions for SG tube plugging criteria. Tubes found by inservice inspection to contain flaws with a depth equal to or exceeding 40% of the nominal wall thickness shall be plugged. The following alternate tube plugging criteria may be applied as an alternative to the 40% depth based criteria:

For Unit 2, tubes with service-induced flaws located greater than 14.01 inches below the top of the tubesheet do not require plugging. Tubes with service-induced flaws located in the portion of the tube from the top of the tubesheet to 14.01 inches below the top of the tubesheet shall be plugged upon detection.

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 plugging criteria. For Unit 2, portions of the tube below 14.01 inches from the top of the tubesheet are excluded from this requirement.

BYRON UNITS 1 & 2 5.5 8 Amendment

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program (continued)

The tube-to-tubesheet weld is not part of the tube. In addition to meeting the requirements of d.1, d.2, d.3, and d.4 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. 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.

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

2. For Unit 1, after the first refueling outage following SG installation, inspect 100% of the tubes in each SG at least every 96 effective full power months, which defines the inspection period.

3. For Unit 2, after the first refueling outage following SG installation, inspect 100% of the tubes in each SG at least every 54 effective full power months, which defines the inspection period. If none of the SG tubes have ever experienced cracking other than in regions that are exempt from inspection by alternate repair criteria and the SG inspection was performed with enhanced probes, the inspection period may be extended to 72 effective full power months. Enhanced probes have a capability to detect flaws of any type equivalent to or better than array probe technology.

The enhanced probes shall be used from the tube-to-tubesheet weld at the tube inlet to the tube-to-tubesheet weld at the tube outlet except any portions of the tube that are exempt from inspection by alternate repair criteria. If there are regions where enhanced probes cannot be used, the tube inspection techniques shall be capable of detecting all forms of existing and potential degradation in that region.

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator (SG) Program (continued)

4. For Unit 1, if crack indications are found in any SG tube, then the next inspection for each affected and potentially affected SG for the degradation mechanism that caused the crack indication shall be at the next refueling outage. For Unit 2, if crack indications are found in any SG 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, then the next inspection for each affected and potentially affected SG for the degradation mechanism that caused the crack indication shall be at the next refueling outage, but may be deferred to the following refueling outage if the 100% inspection of all SGs was performed with enhanced probes as described in paragraph d.3.

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.
