as well as Technical Specification (TS) 5.5.9, "Steam Generator (SG) Program,"

and TS 5.6.10, "Steam Generator Tube Inspection Report."

The proposed changes are needed to address implementation issues associated with the inspection periods and to address other administrative changes and clarifications.

The proposed amendment is consistent with TSTF-510, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection,"

as applicable to Steam Generators (SGs) with Alloy 690 thermally treated tubing. 2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Ameren Missouri has reviewed TSTF -510, Revision 2, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection,"

as well as the model safety evaluation dated October 27, 2011 (76FR 66763) provided as part of the Federal Register Notice for Availability.

As described in the subsequent paragraphs, Ameren Missouri has concluded that the justifications presented in TSTF -510 and the model safety evaluation prepared by the NRC staff are applicable to Ameren Missouri and justify the requested amendment for incorporation of the applicable changes to the Callaway Plant Technical Specifications (TSs). 2.2 Optional Changes and Variations The proposed changes include correction of an administrative inconsistency in TSTF -510, Paragraph d.2 of the Steam Generator Tube Inspection Program.

In Section 2.0, "Proposed Change,"

TSTF -510 states that references to "tube repair criteria" in Paragraph d are revised to "tube plugging

[or repair] criteria."

However, in the following sentence in Paragraph d.2, this change was 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 this 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."

Ameren Missouri does not have approved tube repair criteria.

Therefore, the noted sentence is revised to state "tube plugging" criteria. The above correction is consistent with use of the phrase "tube plugging criteria" (as opposed to "tube plugging

[or repair] criteria")

throughout the proposed TS changes for the Callaway Plant, since as noted, Ameren Missouri does not have approved tube repair criteria.

It should also be noted that due to the existing differences in the numbering of Callaway Plant's TSs and the numbering of the Standard TSs (NUREG-1431

), the Callaway Plant TSs to Enclosure to ULNRC-0617 4 Page 4 of5 be revised in accordance with TSTF -510 are numbered differently than those shown in TSTF-510 itself. Specifically, the Callaway Plant TS Limiting Condition for Operation (LCO) titled "Steam Generator (SG) Tube Integrity" is numbered "3.4.17" instead of"3.4.20" (as the TS is numbered in NUREG-1431

). Likewise, the Callaway Plant TS titled "Steam Generator Tube Inspection Report" is numbered "5.6.10" instead of"5.6.7" (as the TS is numbered in NUREG-1431

). These differences are administrative and do not affect the applicability of TSTF-510 to the Callaway Plant TSs. 3.0 REGULATORY ANALYSIS 3.1 No Significant Hazards Consideration Determination Ameren Missouri requests adoption of an approved change to the Standard TSs into the plant specific TSs, in order to revise Technical TS 5.5.9, "Steam Generator (SG) Program";

TS 5.6.10, "Steam Generator Tube Inspection Report";

and Limiting Condition for Operation (LCO) 3.4.17, "Steam Generator Tube Integrity";

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: 1. 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 integrity and SG tube sample selection.

A steam generator tube rupture (SGTR) event is one of the design basis accidents that are analyzed as part of the plant's licensing basis. The proposed SG tube inspection frequency and sample selection criteria will continue to ensure that the SG tubes are inspected such that the probability of a SGTR is 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 SGTR to exceed those assumptions.

Therefore, it is concluded that this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

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

Response:

No. The proposed 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.

Enclosure to ULNRC-0617 4 Page 5 of5 Therefore, it is concluded that this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

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

No. The 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 SG tubes also isolate the radioactive fission products in the primary coolant from the secondary system. These safety functions are maintained by ensuring integrity of the SG 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 SG tubes such that there will not be a reduction in the margin of safety compared to the current requirements.

Therefore, it is concluded that the proposed change does not involve a significant reduction in a margin of safety. Based on the above, Ameren Missouri 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.

4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 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 CFR 51.22( c )(9). Therefore, pursuant to 10 CFR 51.22(b ), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

The .. as found .. condition refers to the condition of the tubing during a 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 LEAKAG . CALLAWAY PLANT 1. Structural integrity performance criterion:

All inse ice steam generator tubes shall retain structural integrity o r the full range of normal operating conditions (includin@

startu , operation in the power range, hot standby, and II anticipated transients included in the design and design basis accidents.

This includes retaining a safety tee or of 3.0 (3DP) 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 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 all SGs and leakage rate for an individual SG. Leakage is not to exceed 1 gpm total for all four steam generators.

CALLAWAY PLANT 5.0-26 Amendment 190 1 Enclosure Attachment 2 to ULNRC-06174 Page 1 of7 ATTACHMENT 2 TECHNICAL SPECIFICATION BASES PAGE MARKUPS BASES (Continued)

APPLICABLE SAFETY ANALYSES LCO CALLAWAY PLANT SG Tube Integrity 8 3.4.17 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 primary to secondary LEAKAGE rate of 1 gpm to the unaffected steam generators.

exceeding 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 released to the atmosphere via a postulated stuck-open atmospheric steam dump (ASD) valve or via a partially stuck-open main steam safety valve (see Ref. 2). 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. 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. 3), 10 CFR 100 (Ref. 4) 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).

,, uaJ'"d' The LCO requires that SG requires that all SG tubes accordance with the Stea 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. (continued) 8 3.4.17-2 Revision 6

BASES LCO (continued)

APPLICABILITY ACTIONS CALLAWAY PLANT SG Tube Integrity 8 3.4.17 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 total for all four steam generators.

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.

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. 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 ff'14a;r; Condition A applies if it is discovered that one or m re SG tubes examined in an inservice inspection satisfy the tub

riteria but were not plugged in accordance with the Steam Generator Program as required by SR 3.4.17 .2. An evaluation of SG tube integrity of the (continued) 83.4.17-4 Revision 6

BASES ACTIONS CALLAWAY PLANT A.1 and A.2 (continued) f/11(fJ;"'J-SG Tube Integrity 8 3.4.17 affected tube(s) must be made. Ste m generator tube integrity is based on meeting the SG performance cri ria described in the Steam Generator Program.

The SG

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, 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 affected tube(s) must be plugged 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.

B.1 and 8.2 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 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and MODE 5 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.

SG Tube Integrity 8 3.4.17 SURVEILLANCE SR 3.4.17.1 REQUIREMENTS CALLAWAY PLANT During shutdown periods the SGs are inspected as required by this 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 foundn 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 period. t'IAa'-,."'"-

The Steam Genera r Program d'etefmines the scope of the inspection and the methods ed to determine whether the tubes contain flaws satisfying the tub

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, 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. 7). 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 5.5.9 contains prescriptive requirements concerning inspection intervals to provide added assurance that the sc;;

<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:

a. Provisions for condition monitoring assessments.

Condition monitoring assessment means an evaluation of the "as found" condition of the tubing (continued)

CALLAWAY PLANT 5.0-10 Amendment

Programs and Manuals 5.5 5.5 Programs and Manuals 5.5.9 Steam Generator CSG> Program (continued) 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 a 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.

CALLAWAY PLANT 1. Structural integrity performance criterion:

All inservice 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 cooldown),

all anticipated transients included in the design specification, and design basis accidents.

This includes retaining a safety factor of 3.0 (3DP) against burst under normal steady state full power operation 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. 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 total for all four steam generators.

3. The operational LEAKAGE performance criterion 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 40o/o of the nominal tube wall thickness shall be plugged.

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.

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.

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.

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

2. After the first refueling outage following SG installation, inspect each SG at least every 72 effective full power months or at least every third refueling outage (whichever results in more frequent inspections).

In addition, the minimum number of tubes inspected at each scheduled inspection shall be the number of tubes in all SGs divided by the number of SG inspection outages scheduled in each inspection period as defined in a, b, c and d below. 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, 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 (continued) 5.0-12 Amendment###

This constitutes the fourth and subsequent inspection periods.

3. 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 not exceed 24 effective full power months or one refueling outage (whichever results in more frequent inspections).

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.
