4. Location, orientation (if linear), and measuredsizes (if available) of service induced indications The eddy current sizing techniques used during the 15R inspection are qualified to determine wear percent through-wall degradation (TWD) at TSPs and at OTSG-B first span IGA indications. A complete list of inspection results for in-service tubes with wear indications 1% to 39% through-wall in OTSG-A and OTSG-B is provided in Appendix 1 of this Attachment. No tubes were found with

> 40% through-wall degradation at any TSP location. Additionally, a complete listing of tubes with first span IGA indications in OTSG-B is provided in Appendix 2. No IGA tubes were found with

_ 40% through-wall indications.

The remaining service-induced indications include the repairable "I-Code" indications. This includes codes for single axial indication (SAI), single circumferential indication (SCI), single volumetric indication (SVI), multiple axial indication (MAI), multiple circumferential indication (MCI), and multiple volumetric indication (MVI). Appendix 3 lists the tubes with service induced indications that were plugged during 15R. Appendix 4 lists the tubes with service induced indications that were reroll repaired during 15R. Both Appendix 3 and Appendix 4 identify the type of indication and, therefore, the orientation of the indication. For example, a SCI code would mean that the indication was circumferentially orientated and a SAI code means it is axially orientated. The measured sizes used for the condition monitoring assessment (length in the axial or circumferential direction and percent through-wall) are also given.

5. Number of tubes plugged or repaired during the inspection outage for each active degradation mechanism No new tubes were sleeved during the 15R outage. The number of tubes plugged or repaired (rerolled) during the 15R outage for each active degradation mechanism is presented below:

Total Tubes Rerolled for Service Induced Degradation 30 7 139*

• The number of unique tubes rerolled is actually 138 because one tube was repaired by reroll for an indication in both the upper tubesheet crevice region and the tube end clad region.

Tubes identified with unacceptable indications were plugged with Alloy 690 plugs roll-expanded into both ends of the tube. Tubes were stabilized, as needed, based on the latest Areva stabilization criteria.

6. Total number and Percentageof tubes plugged or repairedto date At the conclusion of the 15R outage, the following total number and percentage of plugs and in-service repairs (sleeves and rerolls) are installed in each steam generator. Each percentage number is based on 15,531 tubes per steam generator for plugs and sleeves. The reroll percentage is based on each tube end with 15,531 tubes.

OTSG-A OTSG-B Number of Plugs or Repairs Percent of Number of Plugs or Repairs Percent of Total Tubes Total Tubes Plugs = 455 2.9% Plugs = 928 6.0%

In-Service Sleeves = 159 1.0% In-Service Sleeves = 156 1.0%

In-Service Upper Rerolls = 1,100 7.1% In-Service Upper Rerolls = 2,057 13.2%

U.S. Nuclear Regulatory Commission Attachment 3F0508-03 Page 6 of 20 In-Service Lower Rerolls = 125 0.8% In-Service Lower Rerolls= 13 0.1%

7. The results of condition monitoring, includingi the results of tube pulls and in-situ testing During the 15R (2007) outage, a condition monitoring assessment was performed to verify that the OTSG as-found structural and leakage integrity performance criteria requirements were demonstrated for the previous operating cycle.

The results of the primary-to-secondary induced total leakage calculation were determined to be acceptable. The condition monitoring leakage was 0.410 gallons per minutes (gpm) for OTSG-B and 0.393 gpm for OTSG-B. This is compared to an allowable accident-induced leakage limit of 0.699 gpm.

All tubing inspections were evaluated by eddy current testing methods and the results were analyzed.

All indications, except for three indications of degradation, passed the analytical evaluation for structural integrity. The three indications that did not pass the initial screening for integrity (burst) were later verified to be acceptable based on in-situ testing at worst case pressures. No tubes were pulled during the 15R outage.

The results of the in-situ pressure tests follow. Note - The test pressures were increased to include corrections for the temperature conditions of the test and the potential inaccuracy of the pressure test gauge.

1.) Tube 5-36 in OTSG-A was in-situ pressure tested due to freespan axial indications below the fifteenth TSP.

10. Location, bobbin coil amplitude, and axial and circumferentialextent (if determined)for each first span IGA indication, and an assessment ofgrowth for indications in the first span of OTSG B First span IGA is a degradation mechanism specific to OTSG-B, as identified in ITS 5.6.2.10.c.l.

Following the 2005 (14R) inspection, 164 tubes with first span IGA were returned to service. As a result of the 2007 (15R) inspection, no new IGA indications were detected, nor were any first span IGA tubes plugged for any plugging criteria. Therefore, the same 164 tubes (316 indications) in OTSG-B were returned to service with first span IGA indications. Appendix 2 contains the list of tubes in OTSG-B with first span IGA. The list identifies the location, bobbin coil amplitude (volts),

and change in through-wall percentage from 1997, or earliest detected indication, to 2007.

The axial and circumferential extents were not determined for every first span IGA indication, but they were determined for any indication that was new (none detected in 2007) or showed a 5% or greater change (increase) in through-wall dimension from the 1997 or earliest detected indication to the 2007 inspection. The table below provides the required information.

The Appendix 5 "% TW Growth Distribution" graph is based on the difference between the oldest indications (typically 1997) and the most recent (2007).

The average growth of the first span IGA indications is essentially zero. The data shows that some indications appeared to decrease and some increased in depth which is similar to trends in previous outages. An additional review of all the indications that have increased by > 5% TW since the first readings (1997) were performed. The largest increase from that population was an increase of only 2% TW during the last operating cycle since the 2005 (14R) outage. Therefore, the data continues to support the conclusion that the growth of first span IGA indications is essentially stagnant.

Additionally, there were no first span IGA tubes that exhibited a morphology change to crack-like indications.

11. Number of as-found and as-left tubes with TEC indications, number of as-found and as-left TEC indications,the number of as-found and as-left TEC indications as a function of tubesheet radius, the as-found, as-left, probability of detection and new TEC leakage for upper and lower tubesheet indications. The projected accident leakage and an assessment of growth for TEC indications will be provided. An assessment of the adequacy of the predictive methodoloffy in Addendum C to Topical Report BA W-2346P, Revision 0, including assessing the distribution of indications found in each OTSG to ensure the assumption regardingthe similarity of the distribution of indications remain consistent from one cycle to the next and that the assumption of a linear increase in leak rate remain valid.

The number of as-found and as-left TEC indications as afunction of tubesheet radius:

The number of as-found and as-left TEC indications is plotted in Figures 1 through 4. The applicable indications are grouped into radial zones that represent the same zones used for the upper tubesheet region from the original TEC ARC in License Amendment Number 188 and Addendum A. These zones are no longer used to group indications for leakage determination because CR3 is currently implementing License Amendment Number No. 222. The current method allows the use of a probabilistic methodology and a separate radius for each tube/indication. However, the indications are presented this way because the zones represent areas of similar TEC leakage rates and can also be used for trending. The zones and associated radius used for each graph are identified below:

• An assessment of the adequacy of the predictive methodology in Addendum C to Topical Report BA W-2346P, Revision 0, including assessing the distribution of indicationsfound in each OTSG to ensure the assumption of indications remain consistentfrom one cycle to the next and that the assumption of a linear increase in leak rate remain valid. Corrective actions in the event that the assessment indicates the assumptions can not be fully supported:

The predictive methodology from Addendum C to BAW-2346P provides a way to conservatively predict the total amount of TEC assigned leakage at the end of the next operating cycle. The methodology is based on combining the leakage from the following sources:

1. Leakage from detected indications that are left in service (As-left TEC leakage)

2. Leakage from indications that may not have been detected (POD leakage)

3. Leakage increase as a result of the difference between the as-left leakage from the previous outage and the as-found leakage in the current outage (New leakage)

4. Any leakage increase as a result of an increase in the rate of new leakage (Trend leakage)

The inputs to the projected TEC leakage are based on the assumption that the TEC leakage rates will remain relatively consistent or will be increased if an increasing rate is observed. This is based on data from previous outages and a limited number of equivalent data points. When the latest TEC leakage information from 15R (2007) is compared to the previous information, overall similar leakage rates are observed.

U.S. Nuclear Regulatory Commission Attachment 3F0508-03 Page 15 of 20 There was no unexpected increase in the number of "new" TEC indication leakage for OTSG-A, but there was an increase for OTSG-B. For example, from 14R (2005) to 15R (2007) the new TEC leakage for OTSG-A increased only slightly from 0.098 gpm in 2005 to 0.104 gpm in 2007.

For the same time period, the new TEC leakage for OTSG-B increased from 0.058 gpm to 0.131 gpm. However, the long term trend (below) shows that a more normal "new" leakage for OTSG-B has resumed.

12 13 14 15 RFO A OTSG Upper TEC New Leakage ---- A OTSG Lower TEC New Leakage B OTSG Upper TEC New Leakage --9-- B OTSG Lower TEC New Leakage As the figure shows, the "new" leakage has been fairly consistent except for the reduced leakage for OTSG-B in 14R. The "new" OTSG-B leakage for 15R is back to where previous outages have been.

An assessment of the predicted TEC leakage from 14R was performed and compared to the actual 15R TEC leakage. The 14R projected TEC leakage for OTSG-A was 0.351 gpm compared to an actual as-found of 0.302 gpm showing that the prediction was conservative. The 14R projected TEC leakage for OTSG-B was 0.296 gpm compared to an actual as-found of 0.327 gpm which is 0.031 gpm higher than expected. Note that even though the actual TEC leakage was slightly higher than expected, the overall condition monitoring leakage was still less than the leakage performance criteria. The under-prediction for OTSG-B is most likely due to the low "new" leakage in 14R which was used to predict the 15R TEC leakage. The reason for the low 14R "new" upper TEC leakage is unknown, but the 15R "new" leakage is back up to where it has been historically.

To address the under-prediction of TEC leakage in OTSG-B, a large number of tubes with TEC indications were reroll repaired in the upper tube end to remove the TEC indication and associated leakage from the as-left condition of the OTSG. For example, in the 15R outage there were 263 in-service tubes rerolled in OTSG-A to reduce projected TEC leakage while there were 566 in-service tubes rerolled in OTSG-B to reduce the projected TEC as-left leakage. Even with

U.S. Nuclear Regulatory Commission Attachment 3F0508-03 Page 16 of 20 the large number of rerolls and low as-left TEC leakage CR3 applied the equation for projected TEC leakage, including the high "trend" leakage to predict a more conservative leakage value for the upcoming 16R outage.

Therefore, the corrective actions for OTSG-B were to perform several hundred additional reroll repairs to remove TEC indications and associated leakage from service. A review of the historical trends shows that the "new" 15R TEC leakage is back where it has been historically and then combined with the very low as-left leakage will ensure the 16R actual leakage is within its expected range. Additionally, it is also verified that there is sufficient margin in the overall operational assessment leakage even if the TEC leakage were to be under-predicted by a similar amount in 16R.

The radial distribution of the as-found number of indications for the 14R (2005) and 15R (2007) eddy current inspections are shown in the following figures. There are graphs for upper and LTE indication in both steam generators. The graphs are again shown using the same upper radial zones as in the original TEC license amendment. For example, Zone 1 is the inner most area of the tubesheet and Zone 6 is the outer most (periphery area) of the tubesheet. The graphs show a similar trend in the radial location of the as-found TEC indications. OTSG-A upper tubesheet has a higher number of indications located towards the center of the tubesheet that generally decreases as the zones (radius) increases. The 15R number of indications is greater than the 14R indications for Zones 1 through 4 because most of those indications remained in service from previous inspections due to their lower postulated leakage value. In 15R, the number of indications in Zones 5 and 6 are small because the TEC's in these areas are normally repaired (re-rolled) first to reduce the overall postulated TEC leakage. OTSG-A lower tubesheet has only a small number of indications and shows little change. The trend in the number of TEC indications in OTSG-B is similar from 14R to 15R for both upper and lower indications, although the indications are more concentrated in Zones 2 and 3 (upper), and Zones 3 and 4 (lower). The number of as-found indications in Zone 6 of OTSG-B was greater than previous and reflects the same trend as seen in the previous graph of "new" leakage. However, even though the indication trend in Zone 6 has increased from 14R it is back to its previous historical trend and is not unexpected. There are very minor differences in the radial distribution of TEC indications from the previous outage to the current outage, but the overall impact of these differences is not significant. As shown in Figure 3 above, corrective actions for OTSG-B included the removal (reroll) of all TEC indications in Zones 4, 5 and 6 along with most indications in Zone 3. This provides a large margin for future leakage. Therefore, the assumptions used for predicting future TEC leakage based on previous cycle experience and the predictive methodology from Licensing Amendment No. 222 are still considered valid.

This estimated leakage has been evaluated and would not exceed the offsite dose limits of 10 CFR 100 and 10 CFR 50.67 when compared to existing assumptions in the CR3 Final Safety Analysis Report (FSAR) Chapter 14 Safety Analysis. This is based on a review of the Steam Generator Tube Rupture (SGTR) accident assumptions.

The LBLOCA best estimate leakage is less than the FSAR assumptions for SGTR which assumed a flow rate to the secondary side of the affected steam generator to be 435 gpm. The conservative SGTR accident leak rate and assumptions for degraded fuel cladding only result in a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> integrated accident dose a the exclusion area boundary of 0.139 Rem compared to a limit of 2.5 Rem. Therefore, the estimated LBLOCA leakage is bounded by the FSAR evaluation.

15R Inspection - Conclusion The Operational Assessment (OA) evaluated the degradation mechanisms of the CR3 OTSG tubes. The evaluation concluded that the tubes would maintain structural and leakage integrity with reasonable assurance throughout the current operating cycle. This is based on the inspection results and worst-case Monte Carlo type simulations. Additionally, this was the sixth consecutive 100% bobbin coil and UTS MRPC inspection of the in-service tubes and the third MRPC inspection of the LTS.

Therefore, based on inspection results and the OA of the structural and leakage integrity of the remaining in-service OTSG tubing, the OTSG will meet all EPRI Steam Generator Guideline requirements as well as CR3 Technical Specifications for the next operating cycle.

Future Plans CR3 currently plans to replace both OTSGs in the Fall of 2009 during the 16R refueling outage. The OTSGs will be manufactured by B&W Canada and will incorporate tubing made from thermally treated Alloy 690 material. These new OTSGs are expected to provide a long term reliability of the tubes by the replacement of the original Alloy 600 stress relieved tubing with the Alloy 690 material.
