Only six (6) tubes required plugging due to AVB wear. Five (5) tubes were repaired for tube support plate wear at various locations in the steam generators.

All Row 1 and 2 U-bends were inspected in steam generator C using a Plus Point RPC U bend probe. No degraded tubes were identified during this inspection.

Thirty-three (33) of the laser welded sleeves installed in Refuel 8 were examined using a Plus Point RPC probe. This completed the second 100% in-service inspection of the 77 sleeves installed in Refuel 8. No indications of defects were found.

20% of all "dents" or "dings" found by the bobbin coil, with amplitude greater than 2 volts, were further examined using a Plus Point coil to determine whether any IGA/SCC may have initiated due to the tube deformation. No indications were found.

The hot leg top-of-tubesheet examination was performed using dual guide tubes and Plus Point RPC probes. One hundred fourteen (114) tubes were repaired due to stress corrosion cracking or intergranular attack. All tubes were repaired using Inconel 690

51-5023426-01 Section 1 INTRODUCTION This report describes condition monitoring evaluations of steam generator tubing at Callaway. The observed severity of degradation at the end of cycle, outage RF 12, was evaluated to determine if structural and leakage integrity requirements were maintained. The scope of this evaluation included all the forms of tubing degradation observed at RF 12, specifically:

"* Wear at AVB and Tube Support Locations

"* Expansion Transition Axial PWSCC

"* Expansion Transition Axial ODSCC

"* Expansion Circumferential PWSCC

"* Circumferential PWSCC Within the Tubesheet

"* Volumetric Degradation The observed degradation at the RF 12 outage was evaluated in a manner consistent with NEI 97-061, and EPRI guidelines 2'3. The observed degradation did not present serious challenges to the deterministic (3AP or 1.43 MSLB) structural margin requirement at the end of the last cycle of operation.

In terms of an overview of repair scenarios:

"* wear indications at AVBs or tube supports are left in service if maximum depths are sized less than 40% of the wall thickness

"* all other indications are repaired or plugged on detection.

The next section provides the results of condition monitoring evaluations for outage RF 12.

51-5023426-01 Section 2 CONDITION MONITORING Condition monitoring evaluations relative to structural and leakage integrity are presented in this section. The following paragraphs present condition monitoring structural limits for axial cracks, circumferential cracks, volumetric degradation and wear scars for Callaway steam generator tubing. A discussion of leakage integrity then follows. Table 2.1 summarizes the number of indications of tubing degradation discovered at RF 12 and Table 2.2 summarizes structural and leakage integrity evaluation results.

In terms of an overview of steam generator tubing degradation at Callaway 4, axial and circumferential PWSCC has been observed at top of the tubesheet hydraulic expansion transitions for the past four cycles of operation. This is the primary degradation mode.

Occasional instances of ODSCC, both axial and circumferential, have been observed in this same region. Wear at AVB's is present. Approximately 250 wear scars are present in each of the four steam generators. Wear growth rates are low leading to plugging of about two tubes per generator per inspection for each steam generator for depths exceeding the 40% TW limit. Small volumetric indications are observed on a sporadic basis. These indications are plugged on detection as are all other degradation modes with the exception of wear at AVB's.

The inspection scope at RF12 was as follows:

100% Plus Point TTS Inspection "+2/-X" in all SG Hot Legs, Distance X Depends on Location in the Tube Bundle, The Required Distance X to Demonstrate Leakage and Structural Integrity is Defined in WCAP-15932-P 5 in Terms of Four Zones:

Zone A, X = 3.16", outer peripheral ring, 1892 tubes Zone B, X = 5.61", second inner ring, 2352 tubes Page 4 of 27

100% Rows I and 2 U-bend RPC in SG C

All Electro-sleeves (31) in SG A H/L both ECT & UT

All Westinghouse Laser Welded Sleeves (33) in SG C

20% Plus Point Inspection of Dents and Dings >2V in SGs A and D

Special Interest Plus Point Exams as Required No degradation was detected in Electro-sleeves and laser welded sleeves. The first ten rows of tubes at Callaway are thermally treated Alloy 600 tubing. Thermal treatment was performed after fabrication of the U-bends. Since this improves both the residual stress state and material resistance to stress corrosion, no degradation was expected in the Row 1 and Row 2 U-bends and none was observed. No degradation was observed in the sampling Plus Point inspection of dents and dings.

Detected instances of degradation, as listed in Table 2.1, follow the expectations from past experience at Callaway. The next section discusses a quantitative evaluation of degradation trends. Due to regulatory concerns with leakage integrity from possible PWSCC deep within the tubesheet, the inspection depth below the top of the tubesheet with the Plus Point probe was increased from past practice. Table 2.3 lists the indications found solely due to increased inspection depth within the tubesheet. These indications were located in Zones B and C. Leakage integrity was demonstrated via analysis and in situ testing as described in later paragraphs.

Structural limits for axial cracks, circumferential cracks, volumetric degradation and wear scars for steam generator tubing at Callaway are described in the degradation assessment 4 for RF 12. These structural limits provide the framework needed for condition monitoring evaluations and operational assessments.

Page 5 of 27

51-5023426-01 The combinations of wear scar lengths and depths leading to a 3AP burst pressure of 3825 psi are shown in Figure 2.1 for Callaway steam generator tubing. The upper curve, termed the structural limit curve using the nomenclature of the EPRI Steam Generator Degradation Specific Flaw Handbooks, is based on a best fit burst pressure equation and average, at temperature, material properties. The next lower curve is the EOC Allowable Limit curve which is the locus of actual physical degradation lengths and structural average depths leading to a burst pressure of 3825 psi at a probability of 0.95 at 50% confidence, considering uncertainties in both material properties and the burst pressure relationship. The lowest curve in Figure 2.1 is the Condition Monitoring Limit Curve. This curve includes NDE sizing uncertainties as well as uncertainties in material properties and in the burst pressure equation. The Condition Monitoring Limit curve shows the locus of NDE inferred degradation lengths and depths leading to a burst pressure of 3825 psi at 0.95 probability at 50% confidence. Indications with NDE inferred lengths and depths at or below the Condition Monitoring Limit curve meet the required deterministic structural performance criteria for minimum degraded tube burst pressure.

In applying NDE measured degradation dimensions to infer structural integrity, systematic errors, measurement uncertainties, and shape effects must be considered.

Historically, most NDE depth measurements refer to maximum depth. Figure 2.2 shows a plot of maximum wear scar depth from destructive examinations results versus NDE measured depths 7 using the eddy current technique applicable to Callaway. The best fit straight line shows an intercept of 2.92% TW and a slope of 0.96, resulting in a small systematic error. The scatter in actual depth about the best-fit line is normally distributed with a standard deviation of 3.52% TW. This value is termed the standard error of estimate in conventional straight-line linear regression evaluations. From Figure 2.2 it is seen that, at a measured NDE depth of 40% TW, the best estimate of actual maximum depth is 41.3% TW. Actual maximum depths will scatter about this value with a standard deviation of 3.52% TW. A summary of NDE sizing uncertainties applicable to Callaway is listed in Table 2.4. The term modified in reference to ETSS 21409.1 Page 6 of 27

51-5023426-01 indicates that sizing data for several laboratory produced flaws were deleted and sizing uncertainties were recalculated using only laboratory data which is representative of actual service degradation. Certain procedures for doped steam laboratory stress corrosion testing lead to extremely low signal amplitudes well beyond the bounds of pulled tube experience.

Structural integrity typically depends on average degradation depth, not maximum depth. Maximum degradation depths and total degradation lengths are conservative bounds to structurally significant depths and lengths. If more accuracy is required, crack depth versus length profiles need to be considered. The EPRI Flaw Handbook 6 provides a means of evaluating average depth from depth versus length profiles for predominantly axial degradation, whether crack-like or volumetric. Structurally significant. lengths are also defined. The depths and lengths referred to on Figure 2.1 are the structurally significant values. Plotting of maximum depths and lengths on this and later structural limit plots is conservative. Ifdepth/length profiles are not available, pulled tube examination results show that stress corrosion cracks have a roughly semi elliptical shape leading to an average depth equal to the maximum depth divided by a factor of 1.28.

Condition monitoring structural limit plots are shown in Figures 2.3 and 2.4 for AVB wear scars at Callaway. If NDE data is to be compared to the Condition Monitoring Limit curve, a bounding length of 0.3 inches is used, with NDE depth converted to actual depth using Figure 2.2. Given the short length of AVB wear scars, the average depth is assumed to be equal to the maximum depth. The CM curve already contains the 3.52%

TW sizing uncertainty standard deviation. Figures 2.3 and 2.4 show plotted points representing AVB wear scars observed at RF 12. These points fall well below the CM Limit curve. Required structural integrity is demonstrated. Since through wall tearing and burst will not occur at 3AP, leakage integrity at an SLB differential pressure of 2560 psi is also demonstrated.

51-5023426-01 Figure 2.6 illustrates that volumetric IGA indications in steam generators A and D meet 3AP condition monitoring requirements. Of the total of 9 volumetric indications 5 were located at tube support plates and 4 were located near the top of the tubesheet. All are low level indications in terms of extent, depth and signal amplitude. These indications meet both structural and leakage integrity requirements by a wide margin.

Axial PWSCC indications had very short lengths. The maximum indication length was 0.25 inches. Considering material property, burst equation and NDE sizing uncertainties an axial PWSCC crack can be 0.275 inches long and 100% TW and meet 3AP condition monitoring structural integrity requirements. All axial PWSCC indications thus meet condition monitoring structural integrity requirements. Based on data in the EPRI Steam Generator In Situ Pressure Test Guidelines 8 , axial PWSCC indications must exhibit a Plus Point voltage of 2.5 volts before leakage integrity at postulated SLB conditions becomes an issue or sizing is required. The maximum Plus Point voltage for all observed axial PWSCC indications was 1.7 volts. In situ testing of this indication was performed to verify leakage integrity. No leakage occurred at either SLB or 3AP test pressures.

Only one axial indication was determined to be an OD indication with a length of 0.21 inches and an average depth of 27.6 %TW. Using the EPRI Flaw Handbook6 approach the depth/length profile of this indication led to a structural length of 0.19 inches and a structural depth of 33.8 % TW. Figure 2.7 shows that this indication easily meets the condition monitoring 3AP structural integrity requirement. Figure 2.8 shows that SLB leakage integrity is easily demonstrated. Since the Plus Point voltage of this indication was only 0.25 volts, it was substantially under the 0.4 volts threshold for structural integrity and the 0.75 volts threshold for leakage integrity without sizing as established in the Callaway RF12 Degradation Assessment 4 . However, it must be noted that sizing results of indications below the structural and leakage integrity thresholds can be misleading in terms of being grossly overconservative. NDE sizing results above voltage thresholds are the more reliable indicators of degradation severity.

Page 8 of 27

51-5023426-01 The circumferential PWSCC indications found in the vicinity of the top of tubesheet expansion transitions were of very limited circumferential extent. The maximum PDA value was 14 compared to the condition monitoring limit of 62 PDA. Hence, the degradation found at elevations typical of past practice met condition monitoring structural integrity requirements by a large margin. See Figure 2.9. Plus Point voltage levels were all below 1.0 volts satisfying SLB leakage integrity requirements on a voltage threshold basis as described in the Callaway RF12 Degradation Assessment 4.

The only circumferential degradation posing any threat to leakage integrity was located at least 4 inches below the top of the tubesheet. At this depth level, structural integrity is satisfied for degradation of any dimension since tube burst or pull out cannot occur.

The maximum SLB leak rate per tube for any degradation below this level is on the order of 1E-4 gpm based on WCAP-1 5932-P 5 and laboratory tests on rolled transitions With imposed tubesheet hole dilations 9. In situ testing of 14 circumferential indications expected to be 100% TW verified leakage integrity at pressures in excess of 3AP levels.

One of these indications had a PDA value greater.than 96 and a Plus Point voltage greater than 10 volts and exhibited no signs of leakage at either SLB or 3AP test pressures.

Circumferential cracking beyond previous inspection depths in the tubesheet is assumed to be caused by hydraulic expansion of tubes over machining irregularities in the drilled tubesheet holes. The number of possible degradation sites will thus scale with the length of the tubesheet hole. In the worst case steam generator, 14 circumferential PWSCC indications were found at depths previously uninspected with the Plus Point probe. The now remaining uninspected depth is about three times longer than the region found to contain the 14 indications. Thus, an upper bound estimate of undetected degradation within the tubesheet is about 42 indications of a severity matching the 14 detected indications. The upper bound analytical condition monitoring SLB leak rate is then 0.0056 gpm. In situ testing supports the analytical result that only very low leak rate levels are possible. The reported leak rate at normal operating conditions prior to outage RF12 was 0.3 gpd, which converts to 0.0002 gpm. This level challenges measurement capabilities. If it is true and is applied to circumferential Page 9 of 27

51-5023426-01 cracking deep in the tubesheet, it would convert to 0.0012 gpm at SLB conditions per the results of WCAP-15392. Hence the analytical upper bound SLB condition monitoring leak rate is conservative with respect to an adjusted NOP leakage prior to the RF 12 outage.

In summary, condition monitoring structural and leakage integrity requirements are shown to have been met via analysis and verified by in situ testing. Condition monitoring results are summarized in Table 2.2. In situ testing results are summarized in Table 2.5.

SUMMARY

AND CONCLUSIONS Condition monitoring evaluations of steam generator tubing at Callaway were performed using inspection results from outage RF12. The observed severity of degradation at the end of cycle was evaluated to determine ifstructural and leakage integrity requirements were maintained. The scope of this evaluation included all forms of tubing degradation:

"* Wear at AVB and tube Support Location

"* Expansion Transition Axial PWSCC

"* Expansion Transition Axial ODSCC

"* Expansion Circumferential PWSCC

"* Circumferential PWSCC Within the Tubesheet

"* Volumetric Degradation Condition monitoring via analysis showed that deterministic structural margins and leakage integrity were maintained during the last cycle of operation. In situ testing verified analytical expectations.
