Contingency Letter of Commitment Regarding License Amendment Request 252, Revision 0, Once Through Steam Generator Tube Surveillance Program, Tube Repair Roll (Re-Roll) Process (TAC No. MB 1519)

Dear Sir:

Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc. (PEF), hereby submits Special Report 06-01: Results of the Once-Through Steam Generator (OTSG) Tube Inservice Inspection conducted During Refueling 14. This submittal fulfills the requirements of Improved Technical Specification (ITS) 5.7.2.e, which requires submittal of the report to the NRC within 90 days Following output breaker closure. Breaker closure for Crystal River Unit 3 (CR-3) was achieved on December 10, 2005. [Ninety days from this date is March 10, 2006.]

As required by ITS 5.7.2.e, Special Report 06-01 (Attachment) provides the following information:

1. Number and eKtent of tubes inspected,

2. Location and percent of wall-thickness penetration for each indication of an imperfection,

3. Location, bobbin coil amplitude, and axial and circumferential extent (if determined) for each first span Intergranular Attack (]:GA) indication,

4. Identification of tubes plugged or repaired and specification of the repair methodology implemented for each tube, and

5. Number of as-found and as-left tubes with tube-end crack (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. An assessment of the adequacy of the predictive methodology in Addendum C to Topical Report BAW-2346P, Revision Ab1

U.S. Nuclear Regulatory Commission Page 2 of 3 3F0306-01 0, including aisessing the distribution of indications found in each OTSG to ensure the assumption regarding the 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. Corrective actions in the event that the assessment indicates the assumptions can not be fully supported.

Special Report 06-01 also provides information to fulfill a commitment made in Reference 2 to provide a summary of the evaluation performed to calculate a best-estimate of the leakage expected due to a Lar~ge Break Loss-of-Coolant Accident.

This letter also serves to document two minor corrections to data previously provided in the Mode 4 report (Reference 1). These are described below.

1. Page 3 of Reference 1 provides a table summarizing the axially oriented tube end crack (TEC) tubes, indications, and projected accident leakage. The correction was identified while validating information for the attached 90-Day Report with the finalized eddy-current database. A clarifying note to the table states there were 52 tubes with duplicate TEC indications at the upper and lower tube ends for the 902 tubes left in-service in OTSG-B. The amount was based on the as-found tubes versus as-left. One tube with a TEC on both ends was repaired at only one end. As such, the actual number of unique tubes repaired was 51, and there were 903 TEC tubes returned to service.

The projected accidert leakage for OTSG-A was calculated to be 0.347 gpm based on the guidance in Crystal River 3 License Amendment No. 222. This amendment describes how to calculate the projected TEC leakage for the next cycle and provides an example of how to perform the calculation. The example given calculates the projected leakage per steam generator and does not distinguish upper from lower tube ends. The original 0.347 gpm was therefore calculated using the total steam generator trends. The requested information for the 90-Day Report includes a summary of the as-left, probability of detection (POD), new, and trend leakage components for both upper and lower tube ends associated with TEC leakage. The trend leakage for OTSG-A was originally calculated using 0.011 gpm for the upper tube end and -0.004 gpm for the lower tube ends. This resulted in a net trend leakage of 0.007 gpm. While this calculation would satisfy the license amendment, the negative flow essentially represented a credit towards the overall leakage prediction. Therefore, plant staff has chosen to be conservative in the TEIC trend leakage prediction by not applying any credit to any individual upper or lower TEC. The -0.004 gpm flow was changed to zero; only the increasing trend of 0.011 gpm for the upper tube end was credited for the overall TEC trend leakage component.

The methodology from the license amendment did not specifically address the situation where the leakage from one end of a tube is increasing while decreasing at the other end. By ignoring the negative flow from the one end, the OTSG-A projected accident leakage increases by 0.004 from 0.347 to 0.351 gpm. This increase is insignificant for the overall projected TEC leakage and therefore does not affect any conclusions or assumptions of the methodology. The as-left POD and new TEC leakages are all positive and therefore, are unaffected. NCR 184206 was documented in the CR3 corrective action program to address this error. The Mode 4 report

U.S. Nuclear Regulatory Commission Page 3 of 3 3F0306-01 revised information follows. Additionally, clarification in applying License Amendment 222 will be provided in the implementing procedure.

To reflect bo:h these updates, the revised table under item 4 on page 3 of the Mode 4 report is as follows:

OTSG Tubes Indications Projected Accident Leakage UTEILTE UTE/LTE AK 1282/5 1698/8 0.351 gpm B *806/148 1066/161 0.296 gpm

• Thee were 51 tubes that were duplicates between the upper and lower TEC tubes, resulting in 903 distinct tubes left in service.

This letter establishes no new regulatory commitments.

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 1 of 16 SPECIAL REPORT 06-01 RESULTS OF THE ONCE-THROUGH STEAM GENERATOR TUBE INSERVICE INSPECTION CONDUCTED DURING REFUELING OUTAGE 14 Introduction Inservice inspection (ISI) of the Crystal River Unit 3 (CR-3) Once-Through Steam Generator (OTSG) tubes was performed during Refueling Outage 14 (14R), October 29 through December 10, 2005. In accordance with Improved Technical Specifications (ITS) Section 5.7, Reporting Requirements, Progress Energy is submitting Srecial Report 06-01. A diagram of an OTSG is attached in Figure 10.

ITS Section 5.7.2.e states:

The complete results of the OTSG tube inservice inspection shall be submitted to the NRC within 90 days after breakerclosurefollowing restart. The reportshall include:

1. Number and ex;ent of tubes inspected,

2. Location and percent of wall-thickness penetration for each indication of an imperfection,

3. Location, bobbin coil amplitude, and axial and circumferentialextent (if determined)for eachfirst span .GA indication, and

4. Identificationof tubes plugged or repairedand specificationof the repairmethodology implementedfo reach tube.

5. 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 indicationsas afinction of tubesheet radius, the as-found, as-left, probabilityof detection and new TEC leakagefor upper and lower tubesheet indications. An assessment of the adequacy of the predictive methodology in Addendum C to Topical Report BAW-2346P, Revision 0, including assessing the distribution of indicationsfound in each OTSG to ensure the assumption regardingthe similarity of the distribution 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 befully supported.

Additionally, CR-3 committed to provide the primary-to-secondary leakage following a Large Break Loss-of-Coolant Accident (LBLOCA) evaluation.

Demonstratethat the primary-to-secondaryleakagefollowvinzg a LBLOCA, as describedin Appendix A to Topical Repori BAW-2374, Revision I is acceptable based on the as-found condition of the steam generators.

The following information is presented to satisfy ITS Section 5.7.2.e requirements:

1. Number and e -tentof tubes inspected The eddy current testing (ECT) inspection plan and selection of techniques for the OTSG tubes were designed to detect specific degradation mechanisms throughout the OTSG. The ISI of the OTSG tubes during 14R satisfies the requirements of ITS Section 5.6.2.10. The EPRI PWR Steam Generator Examination Guidelines (TR-1003138), Revision 6, Appendix H, describes the performance demonstration requirements for eddy current techniques used for the examination of

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 2 of 16 steam generato. tubing and repairs. These criteria were used as the basis for determination of technique qualification.

A review of the. qualified technique's essential variables was performed to ensure the application of any qualified technique was applicable to the site-specific conditions and is in compliance with 10 CFR 50, AFpendix B, Criteria IX, Control of Special Processes, for qualified nondestructive examination (NIDE) techniques. The eddy current techniques used at CR-3 during the 14R inspection wer5 adequate for the detection and sizing (where applicable) of the damage mechanisms that are both active and potential for the OTSGs.

A technique is a category within an NDE method that describes the examination system, inspection requirements and detection capabilities for specific flaw types in sufficient detail to ensure consistent implementation with adequate confidence. Two ECI' techniques were used to inspect the OTSG tubes as detailed below. ECT techniques are based on the type of probe used for the inspection; bobbin or motorized rotating pancake coil (MRPC), including a +Point' coil.

The bobbin coil. was used to examine 100% of the tubes in service from the secondary-side face of the upper tubesheet (UTS) to the secondary-side face of the lower tubesheet (LTS) in both OTSGs (15,232 tubes in OTSG-A, 14,748 in OTSG-B), excluding the UTS sleeved tubes (159 sleeves in OTS(3-A and 156 in OTSG-B) which were examined from the LTS to the lower sleeve end. Indications identified using the bobbin coil were further characterized using MRPC (containing 0.1L.5" pancake coil and a +loint' coil). MRPC is qualified to detect the known and potential degradation mechanisms, primary water stress corrosion cracking (PWSCC),

intergranular attack (IGA), and outside diameter stress corrosion cracking (ODSCC) in the tubesheet regions and sleeved tubes.

MRPC was used to examine the following specific areas of both steam generators:

> 100% upper and lower tubesheet from the tube end to the secondary-side face (UTS/LTS)

> 34% LTS sludge pile in the kidney region

> 34% Tubes in the Lane and Wedge region (UTS and 15' Support Plate)

> 34% Sleeved Tubes (roll regions UTE and 15'h Support Plate)

> 100% Identified Dents

>;- 100% of Inconel 600 Plugs

> Further characterization of indications identified by the bobbin coil exam

> 100% of the; tubes in B OTSG identified with 15 Span IGA Inspection Summary The bobbin coil inspection resulted in the A and B OTSG being classified with Category C-2 inspection results in accordance with Il'S 5.6.2.10. Specific areas inspected with MRPC were calculated independently for categorization to identify if further actions were necessary to determine the extent of degradation.

The portion of tube within the clad region in both upper and lower tubesheets were identified as a Specific Limited Area (SLA) in 2003, Refueling Outage 13, as defined in ITS, 5.6.2.10.2.d, based on the physical construction of the tube end adjacent to the seal weld heat affected zone and the roll transition regions. The degradation mechanism is primary water stress corrosion cracking (PWSCC) since the indications appear to be inside diameter initiated and is unique to that area and not random in nature. Absolute determination of the degradation mechanism can only be determined by destructive examination (tube pulls). However, since the indications are near the tube ends, the rnethod of destructive examination would likely corrupt the tube sample.

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 3 of 16 Therefore, 100%7o of the non-sleeved tubes in service in the upper and lower tubesheets must be inspected with MRPC each ISI from the tube end inward at least 3" (UTE to UTE-3 and LTE to LTE +3", or 1.5" beyond a re-roll if applicable). During 14R, the entire tube length between the tube end and the secondary face of the tubesheet for both the upper and lower tubesheets were examined with MRPC. The calculation for the overall categorization of the OTSG inspection results did not include the SLAs, as specified in ITS Section 5.6.2.10.2.d.

2. Location andpercent of wall-thickness penetrationfor each indication of an imperfection The through-wall sizing techniques are qualified to assign a percent TWD to tube support plate wear indications and OTSG-B first span IGA indications. A complete list of inspection results for in-service tubes with indications ]% to 39% through-wall in OTSG-A and OTSG-B is provided in Appendix 1 of this Attachment. For indications with a bobbin percent through-wall and rotating coil percent through-wall, the more conservative dimension was used for evaluations.

A complete listing of tubes with first span IGA indications in OTSG-B is provided in Appendix 2.

3. Location, bobbin coil amplitude, and arialand circumferentialextent (if determined)for each first span IGA indication First span IGA is a degradation mechanism specific to OTSG-B, as identified in ITS 5.6.2.10.e.

Following the 2003 (13R) inspection, 167 tubes with first span IGA were returned to service. As a result of the 2005 (14R) inspection, two (2) tubes from this population were plugged; 4-40 and 4045. Neither tube exceeded the Alternate Repair Criteria (ARC), but both were conservatively plugged based on flaw growth. In addition, tube 92-26 was plugged for a rejectable indication in the upper tube end not associated with IGA. Therefore, a total of 164 tubes in OTSG-B were returned to service with first span IGA. Appendix 2 contains the list of tubes in OTSG-B with first span IGA. Appendix 2 is based on the 13R (2003) and 14R (2005) inspections.

CR-3 is also providing additional infornation regarding the axial distribution, percent through-wall (TW) distribution, and percent TW growth distribution of first span IGA in OTSG-B in Appendix 6. Appendix 6 data is based on the oldest indications (typically 1997) as a baseline and the most recent (2005).

4. Identification of tubes plugged or repaired and specification of the repair methodology implementedfor each tube Tubes identified with unacceptable indications were plugged with Inconel Alloy 690 plugs roll expanded into both ends of the tube. A complete list of plugged tubes in OTSG-A and OTSG-B is provided in Appendix 3.

Tubes with unacceptable indications in the UTS and LTS were repaired using a repair roll (re-roll) where applicable, as described in ITS 5.6.2.10.11.b. A complete list of in-service tubes repaired by the re-roll method in OTSG-A and OTSG-B is provided in Appendix 4.

No tubes were sleeved during the 2005 C)TSG inspection.

Tubes with axially oriented tube end cracks (TEC) within the Inconel clad region of the primary face of the UTS and LTS were left in-service using the method described in Topical Report BAW-2346P, Revision 0, as approved in License Amendment No. 188 issued October 1, 1999 and License Amendment No. 222 issued October 31, 2005. The through-wall extent is conservatively assumed to be 100%. Therefore, a leakage value has been assigned to each TEC to calculate the potential primary-to-secondary leakage in the event of a design basis accident.

Other indications of wall loss or cracking are plugged or repaired on detection and are not assigned a percent wall penetration. A complete list of the tubes remaining in service with TEC is provided in Appendix 5.

5. 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, probabilityof detection and new TEC leakagefor upper and lower tube:;heet indications.An assessment of the adequacy of the predictive methodology

• There were 52 as-found and 51 as-lefi tubes that were duplicates between the upper and lower TEC tubes for 14R, resulting in 923 distinct tubes found and 903 distinct tubes left in service.

b. The number of as-found and as-left TEC indications as a fiinction of tubeslheet 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 tubeshect 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 CR-3 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:

d. An assessment of the adequacy of the predictive methodology in Addendum C to Topical Report BAW-2346P, Revision 0, including assessing the distribution of indicationsfound in each OTSG to ensure the assumption regarding the similarity of the distribution of indications remain consistent from one cycle to the next and that the assumption of a linearincrease in leak rate remain valid. Corrective actions in the event that the assessment indicates the assumptions can not befidly supported.

The predictive methodology from Addendum C to BAW-2346P, Revision 0, 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)

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 10 of 16

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

The inputs to the projected TEC leakage are based on the assumption that the TEC leakage rates will remain relatively linear. This is based on data from previous outages and a limited number of equivalent data points. When the latest TEC leakage information from 14R (2005) is added to the existing information, similar leakage rates are observed. There was no unexpected increase in the number of "new" TEC indications. For example, from 13R (2003) to 14R (2005) the new TEC leakage for the "A" OTSG increased from 0.091 gpm in 2003 to 0.098 gpm in 2005. For the same time period, the new TEC leakage for the "B" OTSG decreased from 0.173 gpm to 0.058 gpm. Since the projected leakage for 15R is larger than the 14R as-found, the linear projection method is still considered to be adequate.

The radial distribution of the as-found number of indications for the 13R (2003) and 14R (2005) eddy current irspections are shown in the following figures. There are graphs for upper and lower tube end indication in both steam generators. The graphs are again shown using the same upper radial zones as in the original TEC' license amendment. The graphs show a similar trend in the radial location of the as-found TEC indications. The "A" OTSG upper tubesheet has a higher number of indications located towards the center of the tubesheet that generally decreases as the zones (radius) increases. The 14R number of indications is greater than the 13R indications for zones 1 through 4 because most of those indications remain in service due to their lower postulated leakage value. In 14R, zones 5 and 6 are less than 13R because the TEC's in these areas are normally repaired (re-rolled) first to reduce the overall postulated TEC leakage. The "A" OTSG lower tubesheet has only a small number of indications and shows little change. The trend in the number of TEC indications in "B" OTSG is similar from 13R to 14R for both upper and lower indications, although the indications are more concentrated in zones 2 and 3 (upper),

and zones 3 and 4 (lower). 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 nxt significant. 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. There were no new corrective actions taken as a result of the as-found TEC indications in 14R (2005).

As an additional check, the TEC leakage methodology from License Amendment No. 222 was used with the a:tual TEC leakage data from the 13R (2003) outage to predict the as-found TEC leakage in the 14R (2005) outage. In other words, if the amendment methodology had been implemented in the 13R outage, how would the predicted leakage compare to the actual 14R TEC leakage. This involved calculating TEC leakage with the probabilistic methodology for 13R as-left TEC leakage, 13R POD leakage, 13R New TEC leakage and Trend leakage. Because of having only one cycle of "New" TEC data before 13R (2003), the historical trend data only used one previous cycle worth of data and not two as would be considered in the current amendment.

However, having additional trend data could only make the predicted trend leakage higher and so for these purposes, the trend leakage is adequate. For both OTSG's, the results show that the predictive method over-predicted the actual as-found TEC leakage in 14R. The results further confirm the acceptability of the currently licensed method.

The newly implemented License Amendment Number No. 222 allows the use of reduced TEC leakage rates arid this resulted in total TEC leakage less than half of the previous NRC approved leak rates. The new TEC leak rates and predictive methodology would have allowed CR-3 to not perform any repairs (re-roll or plug) to meet the overall OTSG leak limits. However, as a conservative action in 14R, all tubes found with TEC indications located in the upper tubesheet radial zone 6 (largest leakage zone) were repaired to have zero as-left TEC leakage in that zone.

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 13 of 16 Bubble Test The primary-to-secondary leakage for this operating cycle averaged approximately 2.5 gallons-per-day (gpd) prior to shutdowr. for 14R. In an effort to identify sources of primary-to-secondary leakage, CR-3 performed a secondary-to-primary leakage test of the OTSGs. The leakage test was to identify potential primary-to-secondary leak paths in the UTS region in both OTSGs. The secondary side of the OTSG was filled to the 15'h support plate with water and then pressurized with nitrogen between the 15'h support plate and the UTE. The water level on the primary face of the upper tubesheet was raised to approximately one inch of water to provide a medium to support bubbles for identifying tube leakage.

Three (3) leak sites were identified in OTSG-A and thirty-four (34) leak sites were identified in OTSG-B.

The leaking sites (bubbles) were all associated with the upper tube joint and tube end. The higher number of leaking tube ends in 'JTSG-B was expected based on the tube end damage caused by loose parts in the 1978 timeframe. All tubes identified with leakage during the bubble test were repaired by re-rolling or plugging. Several leak indications may be attributed to TEC. Tubes identified as leak sites without a corresponding ECT indication were conservatively removed from service. Primary- to-secondary leakage after 14R has been redu-ed to approximately 1.5 gpd.

One leaking Alloy 600 welded plug (B75-12) was removed and replaced with an Alloy 690 rolled plug.

Dent Inspection The dent inspection scope originally included 34% of the dents from the (LTS+ 4" to UTS) plus 100% of the dents next to explosive plugs, plus 34% of the LTS crevice/kidney region. Since two dents were detected with flaw like indications (SG-A tube 35-89 and SG-B tube 73-55), a full 100% MRPC expansion to include all dents was performed. No additional flaws were identified in dents.

Bobbin Coil Technique Qualification The bobbin coil technique qualification for the detection of intergranular attack (IGA) or outside-diameter stress corrosion cracking (ODSCC) was revoked for use at CR-3 for inspection of the tubes within the upper and lower tubesheet areas. The rotating coils (RC) technique identified axial indications, indicative of axial groove IGA, that were not detected by bobbin technique performed during this refueling outage.

The indications were beyond the transition region in the unexpanded area of the tube (within the tubesheet). The degradation detected by the RC' technique is perceived to be IGA; however, the exact degradation mechanism in not known. The indications were evaluated for structural and leakage integrity and determined to be acceptable.

The bobbin coil technique had been used as a method to detect IGA and ODSCC within the tubesheet region, outside of the roll-transition region. The failure of the bobbin technique to detect these indications means that this technique is not reliable to detect groove IGA within the tubesheet. l As the bobbin technique was determined to not be reliable for this exam type during this steam generator inspection, the tubesheets (upper and lower) were examined full thickness with the RC technique to ensure tube integrity.

Rolled Alloy 600 Plugs The examination of the rolled Inconel Alloy (600 plugs revealed four plugs with unacceptable axial indications. All indications were on the non-pressure boundary side of the roll joint and axial in nature.

The plugs were removel and replaced with rolled Inconel Alloy 690 plugs except for one plug that was replaced with a Remote Welded Inconel Alloy 690 plug. This is because the original roll plug head broke off during the removal process, and only a weld plug could be used in that location.

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 14 of 16 Tube Reroll Installed in 1999 Identified in 2005 During the 14R tube inspection, an existing tube re-roll was identified in tube 71-109 in B-OTSG during the eddy current of the upper tube sheet that we.s not identified in the CR-3 repair database for tracking.

14R (2005) was the first time the motorized rotating pancake coil (MRPC) was used to examine the entire length of the upper and lower tubesheets in both OTSGs and was the reason that the re-roll was discovered. No additioaal unidentified repairs were found in either OTSG. Investigation determined that the re-roll was installed in 1999. Since the repair was not identified in the repair database, the re-roll was not inspected in subsequent outages as required.

During 1IR and 12R, the eddy current tube repair lists were manually entered in the database. When a repair is performed, the location of tube repairs are verified by the repair task lead and by the vendors' quality control. CR-3 engineers review the repair list to ensure the tubes with defects that require repair are in fact repaired. The tube did not have a flaw in 1999, 2001, or 2003 which required the tube to be repaired; the tube was inadvertently re-rolled. The tube remained in service after the 14R outage.

In 1999, the vendor inadvertently re-rolled several tubes due to a robot calibration error. This tube may have been among the other tubes with inadvertent re-rolls. Typically, all repairs are entered in the repair database regardless of the reason for the repair. The other inadvertent re-rolls were added to the repair database. This tube re-roll should have also been added to the database. In 13R and 14R, the vendor used an electronic repair list which enabled the repair robot to travel only to those tubes on the repair list. The electronic list of repairs is automatically loaded into the repair database.

This error was entered into the CR-3 corrective action program.

In-Situ Pressure Test During 14R, tubes with rejectable indications were evaluated for in-situ pressure and leak testing in accordance with EPRI Report TR-1007904-R2, "Steam Generator In-Situ Pressure Test Guidelines,"

Revision 2. These guidelines utilize sequential screening criteria, i.e., indications that exceed the threshold value for the first screening parameters, are evaluated against the threshold value for the second screening parameter. The screening thresholds (length, depth, and voltage) are reduced to account for uncertainties in the material properties, burst pressure regression parameters, burst pressures relative to the regression, and NDE. sizing.

Indications in two tubes did not pass the analytical in-situ screening criteria for the tube; therefore, CR-3 performed in-situ pressure testing of one tube in OTSG-A and one tube in OTSG-B. The tube in OTSG-A was selected because of an axial indication in the freespan approximately 3.33 inches below the 15h tube support plate. The tube in OTSG-B was selected due to two circumferential indications approximately 0.25" above the secondary face of the UTS. The indications represented the largest radial indication and largest response voltage.

The test pressure and loading were based on accident induced differential pressure as required. No leakage from the tubes occurred. The indications were re-tested with ECT following the pressure test.

After the pressure test, Tube A3-30 did show a change in voltage response and length, but still maintained its structural and leakage integrity. Tube B73-55 showed no appreciable change in size or voltage. Both tubes were plugged after testing.

U.S. Nuclear Regulatory Commission Attachment 3F0306-01 Page 15 of 16 Best-Estimate Leakage Following a Large Break Loss-of-Coolant Accident (LBLOCA)

Demonstrate that the primary-to-secondaryleakagefollowing a LBLOCA, as describedin Appendix A to Topical Report BAIV-2374, Revision 1 is acceptable based on the as-found condition of the steam generators.

Following the 14R inspection of the Upper and Lower Tubesheet roll region, the best-estimate leakage following a LBLOCA that could occur from as-found circumferential cracking near the tubesheet rolls has been determined tc be 5.5 gpm in OTSG-A and 3.3 gpm in OTSG-B. 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 FSAR Chapter 14 Safety Analysis. This is based on a review of the Steam Generator Tube Rupture (SGTR) accident assumptions from Chapter. 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 at the exclusion boundary of 3.139 Rem compared to a limit of 2.5 Rem. Therefore, the estimated LBLOCA leakage is bounded by the FSAR evaluation.

Condition Monitoring Assessment The results of the ECU inspection during the 14R OTSG inspection were evaluated in a Condition Monitoring (CM) Assessment. The CM Assessment relative to leakage integrity met the performance criteria. The CM evaluation also concluded that structural requirements for all identified degradation mechanisms were met f:r the limiting accidents.

Conclusion The Operational Assessment (OA) evaluated the degradation mechanisms of the CR-3 OTSG tubes. The evaluation concluded that the tubes would maintain structural and leakage integrity with reasonable assurance throughout tLe current operating cycle. This is based on the inspection results and worst-case Monte Carlo type simulations. Additionally, this was the fifth consecutive 100% bobbin coil and UTS MRPC inspection of the. in-service tubes and the second MRPC inspection of the LTS.

The bobbin coil inspection resulted in Category C-2 as described in ITS 5.6.2.10. The overall classification for the inspection performed was C-2 for both steam generators. The classification of the SLAs inspection in both steam generators was C-3. The SLA calculation was not included in the overall categorization of the OTSGs, as previously discussed.

Therefore, based on inspection results and the IDA of the structural and leakage integrity of in-service OTSG tubing, the inspection interval between 14R and 15R will be 24 effective full power months.
