Steam Generator Tube Inspection Report Page 3 of 16 EOC 21 Refueling Outage Introduction The TMI-1 replacement steam generators are AREVA Enhanced Once-Through Steam Generators, which are vertically mounted once-through heat exchangers with a counter-flow design. The EOTSGs have 15597 Alloy 690 thermally treated tubes, 0.625" nominal outer diameter (OD) with a 0.0368" wall thickness. The two steam generators are designated SG A and SG B. The tubes are supported by 15 tube support plates (TSPs) that are made of stainless steel, are 1.18" thick, and have trefoil broached holes. The uppermost TSP (15S) has 1740 drilled holes for the tubes at the outer periphery of the tube bundle.

During the period of9/18/2017 to 10/7/2017, TMI-1 was shut down for Refueling Outage T1R22.

While the unit was shut-down, Exelon performed examinations of the alloy 690TT tubing in the "B" Enhanced Once-Through Steam Generator (Henceforth referred to as "SG B"). The examinations were performed in accordance with Technical Specification (T.S.) 4.19 and 6.19.

The SGs, at the start of TlR22 (End of Cycle 21), have operated for a cumulative 7.266 Effective Full Power Years (EFPY) since their replacement in the fall of 2009 (T1Rl8). The EFPY history for the SGs is presented below in Table 1.

Table 1: TMI-1 Replacement SG EFPY History Effective Full Power Cycle Inspection Outage Years (EFPY) 18 1.720 TlRl 9 (Fall 2011) 19 1.876 TlR20 (Fall 2013) 20 1.890 T1R21 (Fall 2015) 21 1.780 T1R22 (Fall 2017)

Note: TMI-1 Replacement SGs were installed in TIRI8 (Fall 2009) and began operation in cycle 18.

Technical Specification 6.9.6 requires a report be submitted within 180 days after the average

.reactor coolant temperature exceeds 200°F following completion of an inspection performed in accordance with TS 6.19, Steam Generator (SG) Program. The average reactor coolant temperature exceeded 200°F on 10/6/2017.

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.

(TS 6.9.6.a.) The Scope of inspections performed on each Steam Generator:

The T1R22 examinations of SG B were the fourth in-service inspection following replacement of the steam generators during outage T1RI8. Per TMI Plant Technical Specifications, the TMI-1

Steam Generator Tube Inspection Report Page4 of 16 EOC 21 Refueling Outage SGs, having operated 87.192 EFPM at T1R22, are in the first 144 effective full power month (EFPM) inspection period. During TlR22 visual and eddy current inspections were performed in the 'B' steam generator only.

Visual inspections were performed on: (1) 100% of installed tube plugs (Hot & Cold Leg) in SG B and (2) the channel head and tubesheet cladding (Hot & Cold Leg) in SG B. No conditions adverse to quality (i.e. degradation) were found during the Visual Inspections. All tube plugs were found to be in the as-installed configuration with no evidence of degradation or leakage.

During TIR22, all in-service tubes in each steam generator were examined over their entire length using the bobbin coil probe. A combination bobbin/array coil probe was used to examine a two-tube deep periphery tube population in the 'B' steam generator. The data from the array probe was evaluated for the detection of foreign objects in the span between the lower tubesheet and the first support plate. In addition, array probes and/or rotating probes were used to examine tubes with indications identified during the TIR22 bobbin coil examinations. This population of tubes was referred to as special interest (SI) tubes (See Table 2 for additional information). Table 2 illustrates the total scope for TIR22 eddy current examinations.

(TS 6.9.6.b.) Degradation mechanisms found:

The eddy current examinations identified two active degradation mechanisms. The first mechanism is tube-to-tube support plate (TSP) wear. The second mechanism is tube-to-tube wear (TTW). Both degradation mechanisms were identified previously during T1Rl9, TIR20, and TlR21 examinations.

Steam Generator Tube Inspection Report Page 6 of 16 EOC 21 Refueling Outage (TS 6.9.6.c.) Nondestructive examination techniques utilized for each degradation mechanism:

Multiple EPRI Examination Technique Specification Sheets (ETSSs) were used during TIR22.

Tube-to-Tube Support Plate (TSP) Wear:

• ETSS 96043.1 (Rev. 2; Bobbin) was used for all detection and depth sizing of tube wear at the Broached TSP intersections.

• ETSS 11956.3 (Rev. 2; Array) was used for special interest characterization of select flaws (See Table 2) and to size.flaws detected outside the bounds of the bobbin wear calibration.

• ETSS 27901.1 (Rev. 1; +Point') was used for depth sizing of wear indications located at Drilled TSP intersections (This is RPC exam type listed in Table 2). Note: Only the 15th support plate periphery has Drilled TSP intersections Tube-to-Tube (TTW) Wear:

All TTW wear was detected and sized using bobbin ETSS 13091.1 Rev. 0.

(TS 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 OIS through 15S with 01 S being the bottom TSP. Exhibit 1 includes a listing of all service induced indications for "B" Steam Generator (SG B).

Tube-to-Tube Support Plate Wear:

The TSP wear is located primarily at or above the 7th TSP with the highest number of indications occurring at the 8th TSP. The deepest indications were primarily located at the 10th through 14th TSPs. The radial location of the TSP wear indications is more towards the periphery at the higher tube support plate locations.

In SG B, 6729 broached TSP wear indications were identified in the TIR22 inspection using the bobbin probe (see Exhibit 1). Most of these indications were located at or above the gth TSP. The deepest indications were primarily located at the 1oth through the 14th TSPs. The deepest bobbin indication (59%TWD in tube 105-3) consisted of 2 flaws at 2 lands at the same tube support; one had a maximum depth of 44%TWD and a structural depth of 40.4%TWD and the other a maximum depth of25%TWD and structural depth of24.3%TWD as measured with the array coil. The second deepest bobbin indication (58%TWD in tube 5-14) also consisted of2 flaws at 2 lands at the same tube support; one had a maximum depth of 49%TWD and a structural depth of 40.9%TWD and the other a maximum depth of 18%TWD and structural depth of 15.8%TWD as measured with the array coil. Array sizing rather than bobbin was used because the qualification and calibration curve for the bobbin technique (ETSS 96043.1 Rev 2) is limited to

Steam Generator Tube Inspection Report Page 7 of 16 EOC 21 Refueling Outage sizing wear at a single broached TSP land. Since there were indications at 2 different lands at that TSP elevation, bobbin sizi ng of the indications was not accurate and provided an overestimated indication depth. Therefore, the array coil was used for depth and length sizing these indications individually since the calibration curve fo r this technique is not affected by wear at multiple lands.

Additionally, SG B had 13 indications of Drilled TSP wear with the largest being 28% through wall, the same indication was sized at 25%TWD in T1R21. No tubes were plugged in SG B for Drilled TSP wear.

Figure 1 shows the distribution of broached TSP wear indications by depth.

Steam Generator Tube Inspection Report Page 8 of 16 EOC 21 Refueling Outage Tube-to-Tube Wear:

During the TIR22 inspection, there were 288 indications of TTW reported in SG B. All of these indications were relatively shallow with the deepest measuring 19%TWD The majority of TTW indications are located between the 8th and the 9th TSPs, fourteen indications were located between the 7th and 8th TSPs, six other indications were located between the 4th and 5th TSPs, and one indication was between the 3rd and 4th TSPs. Most of the tubes with TTW indications are located between 30"-45" from the center of the bundle. Generally speaking, there is a ring of tubes with indications.

The wear indications are essentially centered axially between the tube support plates and are typically in pairs with similar through wall depths. In some cases, there is a cluster of three or more affected tubes.

Tube-to-tube wear has been reported and sized by different techniques since its initial discovery.

Array probe, +Point', and bobbin probe have been used for sizing. Array and +Point' are capable of distinguishing multiple wear indications at the same axial location, but bobbin is not.

Because the bobbin technique tends to conservatively oversize tube-to-tube wear and this degradation mechanism has not challenged the TMI Operational Assessments, bobbin ETSS 13091.1 was developed and qualified for detection and sizing of all TTW beginning in Tl R2 l.

To allow depth comparisons for growth rate calculations, TIR20 bobbin data were re-analyzed for TTW and sized with ETSS 13091.1, with the results recorded into AREVA's FDMS database for comparison with future results. As such, counts of TTW wear indications may seem to decrease from TIR20 to TIR21 because the bobbin probe does not distinguish multiple wear indications at the same axial location.

Figure 2 shows the distribution of the TTW indications by percent through-wall.

During the Tl R22 outage 52 tubes were plugged in SG B. Nine tubes were plugged based on indications at or above the Tech Spec limit of 40% TWD. 42 tubes were plugged to support the operational assessment plugging limits. One tube was plugged based on engineering judgment due to flaw morphology and proximity to nearby tubes being plugged for similar but deeper indications. In the course of plugging tubes based on flaw depths that met the screening criteria, numerous smaller flaws in the same tubes were also removed from service.

(TS 6.9.6.f.) The number and percentage of tubes plugged to date, and the effective plugging percentage in each steam generator:

There were no tubes plugged prior to T1R19. Table 3 shows the number of tubes plugged during each of the four steam generator inspections and the cumulative number of tubes plugged to date.

The effective plugging percentage is the same as the actual plugged tube percentage. Following TIR22, the effective plugging percentage for SG B was 1.58%.

Steam Generator Tube Inspection Report Page 11 of 16 EOG 21 Refueling Outage (TS 6.9.6.g.) The results of condition monitoring, including the results of tube pulls and in-situ testing:

The observed degradation in the TMI-1 SG Bat the end of Cycle 21 (T1R22) was evaluated to determine if structural and leakage integrity requirements were met. The evaluation was consistent with NEI 97-06, and the applicable EPRI Guidelines. The observed degradation was shown not to present challenges to the structural integrity at the end of the operating interval or challenge required leakage integrity limits under postulated accident conditions.

No primary-to-secondary leakage occurred during Cycle 21. No tubes were pulled during the TlR22 steam generator inspections and no tubes required or were in-situ pressure tested in T1R22.

Tube-to-Tube Support Plate Wear:

A total of 6729 indications of tube wear at the broached tube support plates and 13 indications at drilled tube support plates were reported during the T1R22 inspection in SG B. The Condition Monitoring (CM) limit for TSP wear is a function of the depth, length, and shape (taper) of the wear profile.

Figure 3 and Figure 4 show the CM limit as a function of length and depth for the bobbin coil (ETSS 96043.1) and array coil (ETSS 11956.3) techniques, respectively. As shown in Figure 3, the CM limit for an indication with a structural length of 1.18" is -54%TWD when sized by the bobbin technique. Assuming a bounding flaw structural length equal to the entire thickness of the TSPs ( 1.18"), all indications except two met the structural integrity performance criteria by analysis based on bobbin sizing (ETSS 96043.1). The largest indications detected and sized by bobbin were 59%TWD in tube 105-3 at 14S and 58%TWD in tube 5-14 at l lS. Since the indications, as sized by bobbin, were not shown by analysis to meet the bobbin CM limit, the indications were line-by-line profiled using an array probe and ETSS 11956.3 to obtain a structurally equivalent length and depth, which was compared to the CM limit for the array technique. The tubes were each found to have two distinct wear indications on different lands of the same support plate, a condition for which the bobbin technique ETSS 96043.1 is not qualified to size. This is because the bobbin probe is incapable of distinguishing multiple indications at the same elevation and generally sums the depths of the indications, leading to an overestimation of the measured indication depth. ETSS 11956.3, using an array probe, is a qualified technique capable of resolving multiple indications at the same elevation and accurately sizing each indication at each land. As shown in Figure 4, using array probe data for the structural equivalent depth and length for the largest indication in each tube, tubes 105-3 and 5-14 also met structural integrity performance criteria by analysis. For reference, these values were 40 .4%TWD structural equivalent depth and 1.10 in. structural equivalent length for tube 105-3 and 40.9%TWD structural equivalent depth and 0.37 in. structural equivalent length for tube 5-14.

Other than tubes 105-3 and 5-14, the next deepest indication reported by bobbin was 51 %TWD (105-4 at 15S) Therefore, as a conservative measure this indication and numerous others in the upper range of the bobbin depth distribution were sized with array and evaluated for CM compliance. The array evaluation of the 51 %TWO indication initially sized by bobbin also

Steam Generator Tube Inspection Report Page 12 of 16 EOC 21 Refueling Outage showed wear at 2 lands at the same TSP, measuring maximum depths of 34% and 32%TWD.

The 34% and 32%TWD values were obtained from the " line-by-line" sizing data. Therefore, this indication and all remaining TSP wear indications passed condition monitoring analytically with no need for in situ pressure testing.

It should also be noted that axial loading acting on the circumferential extent of the wear scar was also considered and is not limiting. Large Break Loss of Coolant Accident (LBLOCA) conditions were also considered during the CM evaluation. For LBLOCA events, the limiting load is the axial load created by the large tube-to-shell temperature differential that develops as the tubes cool faster than the shell. Structural integrity is satisfied with 100%TW wear indications with a total circumferential extent of I 07 degrees. Converting this to a PDA gives a PDA of 29.7%. Since none of the detected indications approached I 00% TWO, structural integrity under postulated LBLOCA conditions is satisfied.

Thirteen tubes in SO B confirmed wear at the 1SS drilled tube support plate locations. The deepest indication detected (tube 46-118) had a measured depth of28%TWD. As shown in Figure 5 this is well below the CM limit of 53%TWD for a 360 degree, uniform thinning indication with a length of 1.2", which are extremely conservative bounds. A structural profile was performed and a structural equivalent length of 0.3" and a structural equivalent depth of 18%TWD. This CM limit was determined using methodology defined by the EPRI Flaw Handbook Calculator.

The indications at the drilled TSP locations were also evaluated for structural integrity at LBLOCA conditions. Measured circumferential extents varied from 0.23 to 0.89 inches. The max Percent Degraded Area PDA of any drilled TSP indication was 10%, satisfying the 29.7 PDA criterion discussed above. Since none of the indications approached this depth, the LBLOCA criterion is also met for this mechanism.

Tube-to-Tube Wear:

A total of288 indications of tube-to-tube wear (TTW) in 280 tubes were reported during the Tl R22 inspection. More indications were reported in TIR19 and TIR20 because TTW was evaluated with an array coil, which distinguishes multiple indications at the same axial location, while bobbin does not. Bobbin ETSS 13091. 1 was used for detection and sizing of TTW in Tl R21 and T 1R22.

Bobbin data from Tl R20 were re-analyzed with ETSS 13091.1 and bobbin depths recorded in the TIR20 database to facilitate growth rate calculations for TTW. When re-analyzed with bobbin ETSS 13091.1 before Tl R2 l , SG B had 276 TTW indications.

Most (270) of the TTW indications identified in SG B TIR22 were located between the 8th and the 9th TSPs. 12 indications were located between the 7th and 8th TSPs, 6 indications were located between the 4th and 5th TSPs. The freespan length between the 8th - 9th and 4th - 5th TSPs is 37.82" between the edges of the two TSPs. The freespan length between the edges of the 7th - 8th TSPs is 38.82". Therefore, a bounding structural length of 39" for all TTW indications was used in the CM evaluation. The NOE lengths of these indications were not measured in TIR21 or T1R22 because of the slowly-changing nature ofTTW and the fact that the longest indication measured in Tl R20 was less than 8.2" long Therefore, using a structural length of 39" (i.e., assuming a completely flat wear shape along the entire TSP span) is extremely conservative. Using this bounding structural length, all indications of tube-to-tube wear met the structural integrity performance criteria with ample margin .

Figure 6 shows the CM limits as a function of length and depth for the bobbin coil TTW technique. As shown in the figures , the CM limit for an indication with a bounding structural

Since the deepest NDE depths were I 9%TWD in SO B tubes 22-63 and 46-84 (which were also 19%TWD in Tl R2 l ), all tube-to-tube wear indications passed condition monitoring analytically with no need for in situ pressure testing.

Screening for in situ pressure test candidates was performed in accordance with the EPRI In Situ Pressure Test Guidelines.

During the Tl R 19 inspection (2011 ), all the tube-to-tube wear indications were measured for circumferential extent. The Tl Rl 9 indications generally had circumferential extents of 50 to 70 degrees. During TI R20, there was one tube with four tube-to-tube wear indications in the same span. These indications had a combined circumferential extent of 147 degrees. Based on the allowable PDA of 29.7%, an allowable depth of 59.4%TWD is obtained for a postulated bounding 180-degree circumferential extent (29.7% x 360 I 180). Since none of the measured depths in Tl R22 approached this value, structural integrity under postulated LBLOCA conditions is satisfied.
