Page 1 of 14 Overview During the period of 10/25/2011 to 11/25/2011 TMI-1 was shutdown for Refueling Outage TIR19. While the unit was shutdown, Exelon performed examinations of the tubing in the steam generators (SG). The examinations were performed in accordance with Technical Specification 4.19 and 6.19.

Technical Specification 6.9.6 requires a report be submitted within 180 days after the average reactor coolant system temperature exceeds 200°F following completion of an inspection performed in accordance with Section 6.19, Steam Generator (SG) Program.

The average reactor coolant temperature exceeded 200'F on 11/22/2011.

In Reference 1, Exelon Generation Company, LLC (Exelon) made the following commitment relative to tube integrity following a large break loss of coolant accident (LBLOCA).

"Provide the NRC with the structural limit(s) associated with the most limiting LBLOCA for the replacement SGs as part of the next SG tube inspection report (required by technical specifications) following completion of the next inspection of the tubes in the replacement SGs."

As required by the technical specifications and the commitment contained in Reference 1, the following information is being submitted LBLOCA Structural Limits The limiting loads for the LBLOCA event are the axial loads that result from the temperature difference between the tube and the shell as the tube rapidly cools in relation to the slow cooling shell. The maximum tube load is limited by the yield strength of the material. For TMI, the limiting load is 3104 lbs based on the average material properties of the TMI tubing.

The allowable circumferential extents for a 100% through-wall flaw at the yield axial load of 3104 lbs are:

Best estimate structural limit = 0.63 inches which equals 123 degrees End of Cycle, High Probability limit = 0.55 inches which equals 107 degrees The equivalent allowable circumferential extents for a 60% through-wall flaw are:

Best estimate structural limit = (0.63/0.6) = 1.05 inches which equals 204 degrees End of Cycle, High Probability limit = (0.55/0.6) = 0.91 inches which equals 178 degrees The results show the EOTSG tubes can experience degradation with significant amounts of circumferential extent and depth and will not be in jeopardy of pulling apart (rupturing) during a LBLOCA event.

TMI- 12-071, TMI- 1 Steam Generator Tube Inspection Report (T 1R 19)

Page 2 of 14 Tube Support Plate Wear Limits The limits provided above are basic limits for circumferential degradation without any relation to a specific degradation source. At the time of the analysis, the only active degradation in the EOTSG with Alloy 690 tubing was wear at the tube supports. A conservative estimate of circumferential extent based on a flat wear scar that just does intersect the ID of the tube yields an extent of 0.30". A review of the data shows that degradation of this extent would not challenge the structural limits for the tube. Specifically:

The allowable axial strength due to a 100% through-wall wear scar at a single TSP land (0.30")

is:

Best estimate structural limit allowable load = 4130 lbs End of Cycle, High Probability limit allowable load = 3900 lbs These allowable loads are much greater than the limiting yield load of 3104 lbs.

The allowable axial strength due to a 100% through-wall wear scar at two TSP lands (0.60") is:

Best estimate structural limit allowable load = 3184 lbs End of Cycle, High Probability limit allowable load = 2965 lbs The best estimate limit allowable load is greater than the 3104 lb limiting yield load. Although the End of Cycle, High Probability (EOC) allowable load is slightly lower than the limiting yield load of 3104 lbs, due to the conservatism in defining the circumferential extent of the wear scar, it is concluded that the EOC limit is also acceptable for a 100% TW wear at two TSP lands.

During outage T1R19, the structural limits defined above were determined to be applicable to both the tube-to-tube support plate (T-TSP wear) and tube-to-tube wear (T-T wear) identified during the T1R19 examinations. Both the condition monitoring and operational assessment evaluations for both damage mechanisms considered the LBLOCA structural limits and conditions. These evaluations are discussed in section T.S.6.9.6.g of this report.

Information Required by Technical Specification (T.S.) 6.9.6 The following information is required to be submitted per T.S. 6.9.6. The applicable T.S.

paragraph is shown in parenthesis followed by the T.S. reporting requirement.

(T.S. 6.9.6.a) The scope of examinations performed on each SG, The T1R19 examinations were the first examinations following replacement of the steam generators during outage T1R18. In accordance with the requirements of TS 6.19.d.1, the examinations included 100% of the tubes in each steam generator. All of the tubes in each steam generator were examined over their full length using the bobbin coil probe.

A combination bobbin coil / array coil probe was used to examine the periphery tubes (2 tubes deep). The data from the array probe was evaluated for the detection of foreign objects in the span between the lower tube sheet and the first tube support plate. Tubes with anomalies (e.g. dings >1.5 volt, manufacturing buffing marks (MBM) >0.5 volt)

TMI-12-071, TMI-1 Steam Generator Tube Inspection Report (T1R19)

Page 3 of 14 recorded during the pre-service (PSI) examinations were also examined using the array probe.

In addition, array probes and/or rotating probes were used to examine tubes with indications identified during the T1R19 bobbin coil examinations. This population of tubes, referred to as special interest (SI) tubes, included all tubes with indications recorded as I-Codes (i.e. ADI, DSI and NQI), all tubes with tube-to-tube wear and a sample of tubes with tube-to-tube support plate wear.

The total scope of the examinations is as follows:

Notes.

• 520UL = Bobbin Coil Probe, 5 1OXB = X-Probe Bobbin Coil Analysis, 5 1OXP = X-Probe Array Coil Analysis, 520PP = MRPC +Point

• Tube supports are identified as 01S (lower) to 15S (upper).

• Full length examinations are from the lower tube end (LTE) to the upper tube end (UTE).

• Array data for periphery tubes was evaluated in the span from the lower tube sheet (LTS) to the ISt TSP (0IS) for detection of foreign material or loose parts.

TMI-12-071, TMI-1 Steam Generator Tube Inspection Report (T1R19)

Page 4 of 14 (T.S. 6.9.6.b) Active degradation mechanisms found, The eddy current examinations identified two active degradation mechanisms. The first mechanism is tube-to-tube support plate wear (T-TSP wear). The second mechanism is tube-to-tube wear (T-T Wear). Both degradation mechanisms are present in both steam generators.

(T.S. 6.9.6.c) Nondestructive examination techniques utilized for each degradation mechanism, The T-TSP wear was initially screened by the bobbin coil probe. Sizing was also accomplished using the bobbin coil probe and EPRI technique ETSS 96004.1, Rev. 13.

Rotating and/or array probes were used to perform line by line sizing on a sample of indications to characterize the length and width of the degradation and to verify no cracking was present.

The T-T Wear was initially screened using the bobbin coil probe. The screened indications were then sized using the rotating probe and EPRI technique 27905.3, Rev. 0 or the array probe and the TMI Site Qualification technique Rev. 0.

The TMI Site Qualification technique was developed in conjunction with EPRI to allow depth sizing using the array probe. The technique was developed using the same standards used to develop EPRI technique 27905.3 for the detection and sizing of wear using the MRPC probe. The calibration methodology for the array probe is the same as defined in EPRI technique 11956.3, Rev. 0, which was developed for the detection and sizing of mechanically induced wear at stainless steel support plates using the array probe. The technique was developed and qualified in accordance with requirements of the EPRI Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7.

(T.S. 6.9.6.d) Location, orientation (if linear), and measured sizes (if available) of service induced indications, The following information is provided to aid in understanding the location of indications within the SGs. The TMI-1 SGs have 15 tube support plates (TSPs), numbered 01S through 15S with 01S being the bottom TSP. The TSPs are 1.18" thick SA 240 type 410M stainless steel. The distance between the support structures ranges from 35" to 46.38". The tube bundle is essentially circular with a maximum diameter of approximately 114" (maximum radius= 57"). Exhibits 1 and 2 are listings of all service induced indications.

T-TSP Wear The T-TSP wear is located primarily at the 7th through 15th TSP with the highest number of indications occurring at the 8th TSP. At the 8th TSP, the radial location of the T-TSP

TMI- 12-071, TMI-1 Steam Generator Tube Inspection Report (T 1R 19)

Page 5 of 14 wear is approximately the same as the T-T wear indications. The radial location of the T-TSP wear indications is more towards the periphery at the higher tube support plate locations.

In SG A, a total of 952 T-TSP wear indications ranging from 5% - 27% through wall were recorded in 847 tubes. In SG B, a total of 1342 T-TSP wear indications ranging from 5% - 52% through wall were recorded in 1035 tubes. The indications are volumetric in nature and tend to be axially oriented. Length sizing on a sample of indications showed the structural length for most of the indications is < 0.5" with the longest observed structural length being 0.66".

Figures 1 and 2 show the radial distribution of T-TSP wear indications. Figure 3 shows the axial distribution of the T-TSP wear indications.

Page 9 of 14 T-T Wear The T-T wear indications are located primarily in the span between the 8th and 9th tube support plates (counted from the bottom). There is one tube that has tube-to-tube wear between both the 7th and 8th and the 8th and 9th tube support plate. (Including the above tube, there are 5 tubes with wear between the 7th and 8th tube support plate and 2 tubes with wear between the 4th and 5th tube support plate.) All other tube-to-tube wear indications are between the 8th and 9th tube support plate.

Most of the tubes with T-T wear indications are located between 30" - 45" from the center of the bundle. Generally speaking, there is a ring of tubes with indications.

In SG A, a total of 89 T-T wear indications ranging from 1% - 21% through wall were recorded in 74 tubes. In SG B, a total of 206 T-T wear indications ranging from 3% -

19% through wall were recorded in 183 tubes.

The wear indications are essentially centered between the tube support plates and in most cases are in pairs with similar through wall depths. In some cases there is a cluster of three or more affected tubes. The wear indications are axially oriented with lengths ranging from approximately 2" to 8".

Figures 4 and 5 show the radial distribution of the T-T wear indications. Figure 6 shows the percent through wall depth distribution of the T-T wear indications.

Page 13 of 14 (T.S. 6.9.6.e) Number of tubes plugged during the inspection outage for each active degradation mechanism, Thirty-seven tubes were plugged during T1R19. Thirty tubes, all in SG B were plugged for T-TSP wear. Seven tubes, (4 in SG A and 3 in SG B) were plugged for T-T Wear.

(T.S. 6.9.6.0 Total number and percentage of tubes plugged to date, There were no tubes plugged prior to T1R19. The total number and percentage of plugged tubes is as follows.

SG A, Total Tubes = 15,597 Year Outage Number of Cumulative Cumulative Tubes Plugged Plugged Tubes Percent 2009 Fabrication 0 0 0 2009 Baseline 0 0 0 2011 1st ISI 4 4 0.03%

(T.S. 6.9.6.g) The results of condition monitoring, including the results of tubes pulls and in-situ testing, The condition monitoring evaluations demonstrated all identified indications were acceptable at the end of Cycle 18 (T1R19 examinations). There were no tube pulls and in-situ pressure testing was not required. The condition monitoring was evaluated separately for both T-TSP wear and T-T wear. For both degradation mechanisms, the limiting structural performance criterion for TMI- 1 is three times the normal operating differential pressure (NOPD). The evaluations also considered large break loss of coolant accident (LBLOCA) conditions.

T-TSP Wear The condition monitoring limit for T-TSP wear, assuming a length of 1.18" axial length is about 58% through wall, The deepest T-TSP wear indication was 52% through wall with a structural length of 0.48".

TMI-12-071, TMI-1 Steam Generator Tube Inspection Report (TIR 19)

Page 14 of 14 The T-TSP indications were also evaluated for LBLOCA conditions. Structural integrity for LBLOCA conditions is satisfied with 100% through wall flaws at two land areas.

Since none of the wear indications approach 100% through wall, LBLOCA conditions are satisfied.

T-T Wear The condition monitoring limit for T-T wear was established for both the rotating and array probes. The bounding condition monitoring limit for both techniques is greater than 50% through wall, assuming a flaw length of 39". Since the deepest measured T-T wear was 21% through wall with a structural length of less than 10", all condition monitoring conditions were satisfied.

The T-T wear indications were also evaluated for LBLOCA conditions. The LBLOCA conditions are satisfied with a 100% through wall flaw with a 107 degree circumferential extent which results in a percent degraded area (PDA) of 29.7%. The T-T wear flaws generally had NDE measured circumferential extents of 50-70 degrees. Conservatively assuming two flaws, at the same axial location, with 90 degree circumferential extent gives a total circumferential extent of 180 degrees. The resultant allowable PDA for a 180 degree flaw is 59.4% through wall. Since the deepest flaw is 21% through wall all LBLOCA conditions are satisfied.

(T.S. 6.9.6.h) The effective plugging percentage for all plugging in each SG, There are no sleeves or repairs other than plugs installed in the steam generators. The effective plugging percentage is the same as the actual plugged tube percentage.

Following T1R19, the effective plugging percentage for SG A is 0.03% and for SG B 0.2%.

Summary This report meets the reporting requirements for Technical Specification 6.9.6. The information provided relative to the TMI LBLOCA Structural Limits satisfies Commitment 2 from Reference 1.
