Enclosure Steam Generator Tube Inspection Report 1

Steam Generator Tube Inspection Report 1.0 Introduction Seabrook Station is a Westinghouse four-loop pressurized water reactor with Model F steam generators.

The steam generators are U-tube heat exchangers with tube bundles fabricated using thermally treated Alloy 600 tubing. A row and column number identifies each tube. Each steam generator contains 5,626 tubes arranged in 59 rows and 122 columns. Nominal tube OD is 0.688" with a 0.040" nominal wall.

Seabrook Technical Specification section 6.7.6.k and the EPRI Steam Generator Examination Guidelines, Revision 7, define the required inspection periods and their duration. For Alloy 600TT tubing, the first inspection interval is 120 EFPM; the second inspection interval is 90 EFPM; the third and subsequent inspection intervals are 60 EFPM. The inspection during refueling outage 15 (OR15) in the fall of 2012 was the first inspection in the first 60 EFPM inspection interval.

Appendix A provides a list of acronyms and Appendix C provides the list of imperfections.

2.0 Scope of Inspections Performed The inspection scope was required by Seabrook Station Technical Specification 6.7.6.k.d.3 and the EPRI Steam Generator Examination Guidelines, Revision 7. In all four steam generators, the defined inspection scope for OR1 5 was:

• 100% Bobbin examination of tubes, full length except for Rows 1 and 2, which are inspected straight leg sections on both HL and CL. (This includes 100% of Dings/Dents >2V and <5V.)

• 50% of the U-bends in each of Rows 1 and 2 with plus point rotating coil probe.

• 50% of Ding/Dents >5V on the hot leg including the U-bend with plus point rotating coil probe.

• 50% Hot leg TTS, +3"-15.21", plus point rotating coil probe examination (to include 50% of the OXP/BLG signals within the H* depth).

0 Special interest, mid-range plus point rotating coil probe tests at hot leg and cold leg bobbin possible flaw locations (including U-bends), including all "I-code" indications that were new or not resolved after history review.

o Visual inspection of all mechanical and weld plugs.

• 100% inspection of previously reported indications.

• Visual inspection of the channel head in response to NSAL 12-1 "Steam Generator Channel Head Degradation" January 5, 2012 Inspection Expansion An indication of axial ODSCC was detected in SG-C Rl8C1 16 at a dent on the HL of the top-most TSP.

This resulted in an expansion of the inspection to include 100% of the dings/dents >5V plus point rotating probe on the HL of SG-C including the U-bend, a 20% sample of dings/dents >2 _5V on the HL of SG-C using the plus point rotating probe, 100% of the dings/dents >5V at TSP8 on the CL, and a 20%

sample of dings/dents >2 <5 volts at TSP 8 on the CL in SG C using the plus point rotating probe. No 1

expansion was required in SGs A, B and D because the base sampling included 50% of the dings/dent

>5V with the plus point rotating probe.

One indication of free span axial ODSCC was detected by bobbin in SG-B R4C122 above the flow distribution baffle and below the first quatrefoil support plate and confirmed by the plus point rotating probe and the Ghent 3-4 probe. Because a 100% bobbin inspection was completed as the base program, an expansion of the bobbin inspection was not applicable.

During the inspection to confirm the axial ODSCC indication in SG-B R4C122, two additional, very small, indications of axial ODSCC were detected in the same tube approximately 6 inches above the indication detected with the bobbin probe. These additional indications are not in the same axial plane as the bobbin detected indication. No reportable bobbin signal was detected at these two smaller locations.

Secondary Side The following work was performed on the secondary side of the steam generators:

Sludge Lance in SG A, B, C, and D FOSAR in SG A, B, C, and D Upper Bundle In Bundle (UBIB) in SG C Upper Steam Drum Inspection in SG A 3.0 Degradation Mechanisms Found

1. A single indication of axial outside diameter stress corrosion cracking (ODSCC) was observed in SG-C in tube R1 8C 116 at a dent on the hot leg (HL) at the uppermost tube support plate.

2. Three indications of axial ODSCC were detected on tube R4C 122 in SG-B between the flow distribution baffle and the first tube support plate.

3. AVB wear continues as an existing degradation mechanism in the Seabrook SGs.

4. Wear at the flow distribution baffle (indications existing prior to OR1 5)

5. Volumetric indications at tube support plates (TSP).

6. Volumetric indications at, or above, the top of the tubesheet (TTS).

ODSCC A single indication of axial ODSCC (SAI) was detected in SG-C RI 8C 116 at a dent at the HL of the uppermost TSP (08H) the TTS during the plus point >5 volt ding/dent inspection program. There are two historical ding/dents at this location. One at the bottom edge of the TSP (11.35 volts) and the other near the upper edge of the TSP (8.96 volts).

Three indications of axial ODSCC (SAI) were detected in SG-B, R4C122, in the free span above the flow distribution baffle but below the first quatrefoil support plate. See Appendix B for further discussion.

Table 1 summarizes the indications of ODSCC reported during OR15.

AVB Wear AVB wear continues to be an existing degradation mechanism in all four Seabrook SGs. AVB indications were detected in all 4 SGs as expected. Table 2 summarizes the current inspection results for AVB wear. There were six tubes with AVB wear >40% Through Wall (TW). The table also shows the number of new AVB indications and the number of new tubes in which AVB wear was not previously reported.

1. Includes indications on tubes without prior indications

2. New tubes are tubes reported with AVB wear indications that had no prior history of AVB indications.

Wear at the Flow Distribution Baffle In each of SG-A and D, a single wear indication was originally reported at OR09 at the flow distribution baffle (FDB). These signals were attributed to a prior pressure pulse cleaning (PPC) of the SGs, based on the location of the indications relative to the PPC pulser locations. Similar indications have been observed in other Model F SGs at other plants that have applied PPC. The re-examination of these indications at ORI 5 showed that these indications are not changing.

Volumetric (Wear) Indications At or Above the TTS Volumetric indications reported during OR15 are summarized on Table 3, which also includes prior calls, if any, at ORI 3. The table shows that volumetric indications are attributed to either foreign objects (FO), maintenance related wear (MNT), or wear at the tube support plate (TSP).

New Volumetric Wear at Tube Support Plates Isolated occurrences of wear at prior inspections were attributed to impacts with transient foreign objects; the wear depths of the previously reported indications have not changed. New volumetric indications were reported in SG-A in four tubes, in SG-B in one tube, in SG-C in three tubes and in SG-D in one tube. All other volumetric indications were reported previously at ORI 3 without change in the wear depth of the indication. (Small changes are within the uncertainty range of the EC technique.) The new indications are all located at tube support plates, widely distributed over the axial height of the bundle, except for SG-A, R18C45 and SG-B, RICH1. Similarly located indications reported at OR13 and before have not changed in depth. These indications are interpreted as wear at the tube support plates, although prior indications are not observed to grow after the initial report.

The indication on SG-A, RI 8C45, is attributed to a transient foreign object while the indication on SG-B RIC 1I is attributed to maintenance related wear.

Maintenance Related Wear In SGs A, B, and C, indications reported in Row 1, Columns 11, 36, 87 and 112 are all located at approximately 18 inches above the top of the tubesheet, including a previously unreported indication on tube RIC 11. These indications are all maintenance operation induced and are attributed to interaction of 5

the tubes with the sludge lance rail at a prior outage. The sludge lance rail has been re-designed to prevent future tube interaction or aggravation of the existing wear condition. The depths of these indications have not changed since OR13 and before. Indications of this type have been observed in SGs in other operating plants.

Wear at the top of the Tubesheet In SGs-A , B, and C, the volumetric indications approximately at the TTS, previously reported at OR13, and attributed to transient foreign objects, were re-inspected at ORI 5. These indications were sized for depth using the same techniques used in OR13. These indications have not grown (see Table 3) and are not expected to grow since no foreign objects are resident at these locations. No new volumetric indications approximately at the TTS were reported during OR15.

Foreign Objects Wear due to impingement of foreign objects on the tubes is categorized as an existing degradation mechanism due to the confirmation of loose parts in the current and prior inspections at Seabrook.

Foreign objects may be identified by both visual inspection from the secondary side and by EC inspection from the primary side. During the removal process for the upper-bundle-in-bundle (UBIB) inspection tool, a piece of the Delrin enclosure and a small optical lens broke off the tool. Two pieces of Delrin (V4 x 11/4 x 'A)were retrieved from the flow distribution baffle. However a small "sliver" of Delrin and the small optical lens (glass) were not retrieved. The objects were evaluated for their potential to damage the SG tubes and found that these small objects would not cause tube damage in future operating cycles.

During the visual inspection (FOSAR) of the Seabrook SGs, two foreign objects were identified and removed. One object was a short length of bristle and the second was an item that broke apart easily when challenged, suggesting a hard scale. Appendix B summarizes the foreign objects remaining in the SGs after OR15.

Potential Loose Parts (PLP)

Potential loose parts (PLP) indications are summarized in Table 4. The PLP's were reported during the TTS (+3"/-15.21 ") plus point RPC program and the 100% bobbin inspection of the tubes in the primary side EC inspection. Many of the PLP indications had been reported previously. No damage to the tubes was associated with these PLP locations. The only PLP that was visually verified during FOSAR was in SG "A" Row 1. All PLPs in history as well as any new PLPs were tested with plus point, including the bounding tubes, to determine the extent of the PLP.

In SG-A, PLPs were reported on three contiguous tubes in the Row 1 tubes. Because of their location, these PLPs are interpreted as sludge, or sludge rocks, which are benign to the tubes. These tubes remain in service. These PLP indications were visually confirmed as a sludge rock between column 9 and column 10. There was no visible foreign object seen between column 10 and 11. These PLP indications have been reported at prior inspections.

In SG-B, 10 tubes with PLP indications were reported; no damage to any tube was detected at these locations. One PLP was reported above each of TSP's 3 and 5 on the HL in the interior of the bundle.

All other PLPs were reported within a maximum distance of 4.35 inches above the top of the tubesheet Inspection of the adjacent tubes confirmed the absence of PLP signals in the surrounding tubes. Because of their history and location, the PLPs are attributed to sludge rocks and scale which are benign to the tubes. These tubes remain in service. These PLPs were not visually verified.

In SG-C, two adjacent tubes were reported with a PLP signal about 0.1" above the HL TTS. The location of these tubes is typical for expected accumulation of deposits. No evidence of tube damage was found. The tubes remain in service. This PLP was not visually verified.

In SG-D, 7 tubes were reported with PLP signals. The PLP signals were reported in two clusters of contiguous tubes, one on the HL and the other on the CL above the TTS. The location and pattern of 7

these PLPs suggest the presence of deposits at these locations. No damage was associated with any of the PLP signals and the tubes were left in service. These PLPs were not visually verified.

In all four SGs, bulge (BLG) signals were reported just above the tubesheet (see Table 5). All of the BLG indications reported at OR15 were previously reported during OR13 and prior inspections. No degradation was associated with any of the BLG signals.

Bulge (BLG) indications were reported in R22C75 in SG-D at about 1.7 and 2.8 inches above the tubesheet on the cold leg. These indications were reported previously during OR13 and before. No degradation was detected in these BLG signals.

The 15.21 inches distance is the licensed H* value at Seabrook. No evidence of any degradation was found during this inspection.

Plug Inspection The currently installed plugs were inspected for evidence of leakage as characterized by Boron "star" patterns. The borated plugs were categorized in accordance with Westinghouse procedure MRS 2.4.2 Gen-44, Revision 1; "Visual Inspection of Plugs". No dripping plugs were identified; all plugs were found to be dry.

Monitoring for Tube Slippage A condition for licensing H* was to monitor for tube slippage within the tubesheet region.

Monitoring for slippage was accomplished in accordance with the slippage monitoring guidance provided in Westinghouse LTR-SGMP-09-140 "H*; Guidance for Monitoring Tube Slippage Using the Bobbin Probe Data," September 22, 2009 (Proprietary). No tube slippage was detected.

Potential Tube to Tube Wear There are several tubes that were plugged for AVB wear in the first or second inspection. It is postulated that these tubes could continue to wear. The adjacent tubes in the same row are monitored for tube to tube wear. No evidence of any tube to tube contact was found during OR15.

Channel Head Degradation NSAL 12-1 recommended visual inspection of the channel head near the bowl drain line to determine if degradation of the cladding and potential degradation of the channel head base material had occurred.

9

The observed condition is consistent with the manufacturing process and does not exhibit any degradation. It was concluded that a condition similar to that documented in NSAL 12-1 does not exist at Seabrook.

Stuck Bobbin Probe Head During the low row straight leg bobbin examination program (SG B RIC 116) a bobbin probe head became separated from the conduit during the withdrawal process. The probe head was intact with two trailing wires approximately 18 inches in length. The probe had become lodged at the u-bend tangent point. Repeated attempts to push the probe head back out of the tube were unsuccessful. However, the probe head was able to be moved to below the tangent point. Eddy current examination of the entire tube length was successful. There were no indications reported in the tube. An evaluation was completed to allow the probe head and wires in the tube and to remove the tube from service by plugging. The tube was subsequently plugged.

6.0 Pluggini Nine tubes were plugged during OR1 5 at Seabrook as summarized on Table 6. Two tubes were plugged for confirmed ODSCC signals. One tube was administratively plugged in SG-B because an EC probe was stuck near the tangent point on the HL and remains inside the tube. Six tubes were plugged for AVB wear. Table 7 provides the total number of tubes plugged per steam generator and the plugging percentage.

7.0 Condition Monitorine Assessment Results.

a. Four indications of axial ODSCC were detected during OR15, one in SG-C R18C166 associated with a dent at the top tube support and three in SG-B R4C122 located above the flow distribution baffle, separated by significant un-degraded ligaments. All four indications were predicted to have 95% probability at 50% confidence burst pressure greater than the limiting differential pressure of 3759 psid. None of the indications passed the screening criteria for burst and leak testing. All of the indications meet the Condition Monitoring requirements.

b. The maximum observed AVB wear indication (55% TWD) meets the condition monitoring requirements at 95% probability, 50% confidence when all uncertainties are considered at their 95%

probability values.

c. AVB wear continues to be an existing degradation mechanism at Seabrook. The overall incidence of AVB wear in the Seabrook SGs is consistent with the Model F SG operating experience.

d. The previously reported wear at the flow distribution baffle was reported again during OR15.

Examination of the prior inspection signals shows that the signals are not changing. FDB wear is attributed to the application of pressure pulse cleaning of the SGs and is observed in other Model F SGs at the same locations and depths. The magnitude of the wear does not challenge the requirements for condition monitoring.

e. Volumetric indications meet the requirements for Condition Monitoring at 95% probability and 50%

confidence. The maximum observed indication was 36% TWD.

f. The maximum wear attributed to foreign objects was 24%TWD. The maximum existing volumetric indication left in service is 36% TWD; the structural limit for the local wear is 65% TWD. Wear due to foreign objects meets the performance requirements for Condition Monitoring.

g. No pitting was observed.

h. No degradation was observed in the tubesheet expansion zone in the H* distance (TTS- 15.21")

i. The predicted accident induced leakage for H* meets the Condition Monitoring leakage requirements. In SG-B, in which operating leakage has been observed, the predicted leakage from the tubesheet expansion region is 2.24 gpd (.0016 gpm). No leakage was detected from the ODSCC indications in SGs B and C. SGs A and D are free from indications with the potential to leak and have no reportable normal operating leakage. Therefore, the Seabrook SGs meet the Condition Monitoring requirements with regard to leakage.

j. The OR15 inspection results validate the projections and conclusions of the Operational Assessment of the previous inspection at OR13.

11

8.0 Observed Leak Rates Seabrook has tracked detectable normal operating leakage in SG B that has varied between 0.2 gpd and 0.9 gpd during the previous cycle. This very low level of leakage has been detected for several cycles.

9.0 Calculated Accident Induced Leakage For application of H*, Seabrook committed to use a leakage factor of 2.49 for the tubesheet expansion region to determine accident induced leakage for the limiting design basis accident.

The assumed value for accident induced leakage in the Seabrook FSAR is 500 gpd (0.35 gpm) for the faulted steam generator.

Because there is no other degradation mechanism in SG-B that has been shown to be the source of the observed normal operating leak, the entire observed operating leakage is assumed to come from the tubesheet expansion region. Conservatively assuming that the observed normal operating leakage in SG-B is the upper end of the observed range, i.e., 0.9gpd, the predicted accident induced leakage is:

QDBA = 2.49 x 0.9 gpd = 2.24 gpd (=0.0016 gpm)

The predicted accident induced leakage from SG-B, 2.24 gpd, is much less than the assumed accident induced in the FSAR of 500 gpd for the faulted SG.

There is no observed normal operating leakage from SGs-A, C, and D; therefore, the predicted accident induced leakage for each of these SGs is zero.

Because the predicted accident induced leakage from any of the Seabrook SGs is less 1 gpm, the leakage criteria for condition monitoring are met.

10.0 Secondary Side Inspections In OR15 secondary side inspections included Foreign Object Search and Retrieval (FOSAR), Upper Steam Drum Inspection, and Upper Bundle In Bundle Inspection (UBIB).

The UBIB inspection was performed in SG C to assess the effectiveness of the full bundle Advanced Scale Condition Agent (ASCA) application that was performed in OR13 (Fall 2009). The inspection was mainly focused on tube support plates (TSP) 6 and 7. The seventh support plate is the upper most quatrefoil TSP. The locations were columns 76, 78, 92, 93, 95, 96, and 97. For reference the midpoint of the columns (half way across the bundle) would be column 61. These columns were chosen since there are equipment and flow slot alignment conditions that only allow inspection of specific columns.

The results of the inspections show that the quatrefoil lobes are not occluded and are open to flow.

There were no signs of bridging of the lobes. The full bundle iron ASCA was successful in keeping the quatrefoils open to flow.

12

The upper steam drum inspection was performed in SG A. The components that were visually inspected were the feed ring, J-tubes, J-tube to feed ring weld (sample), primary moisture separators, secondary separators, welds, structural components, thermal sleeve, backing rings. In addition, informational UT depth readings were taken at several locations on the feedring to access flow assisted corrosion. The results of the inspection showed that all components are covered with a protective layer of magnetite. No bare metal (rust areas) were noted. The UT depth readings showed no signs of thinning. There were no anomalies noted at the J-tube to feed ring welds.

FOSAR was performed in all four steam generators in the annulus and tube lane. In addition, in-bundle inspections were performed in several columns in each steam generator to assess the effectiveness of the top-of-tubesheet ASCA that was performed in the previous outage (OR14). The in-bundle visuals showed that scale collars still remain on some tubes in the "kidney" region of the steam generator. The kidney region is the region of low cross flow across the tubesheet sheet and is typically located near the center of the tube bundle. The ASCA was successful in reducing the number and size of the scale collars. The FOSAR results were discussed in section 5.0 13

Appendix B Three indications of axial ODSCC (SAI) were detected in SG-B, R4C122, in the free span above the flow distribution baffle and below the first quatrefoil support plate. A non-quantifiable signal (NQI) was detected during the 100% bobbin coil examination program in steam generator B in R4 C 122. The non quantifiable indication (NQI) was confirmed by both the plus point rotating coil probe and the Ghent 3-4 probe to be an axial ODSCC indication. This particular signal was present in history but was not determined to be "flaw like" per the ETSS in the previous inspections. In this inspection, there was a significant change in the eddy current signal. The axial ODSCC indication was .96 volts and measured 0.52 inches in length and 77% through-wall (TW) using ETSS 128432. In addition, two smaller axial ODSCC crack indications were not reported by the bobbin coil but were detected by the plus point rotating coil. The second of the three indications is 0.24 volts, 0.15 inches in length, and 45% TW. The third of the three indications is 0.38 volts, 0.18 inches and length, and 56 % TW. These indications were also sized using ETSS 128432. The three indications are separated by large ligaments and are not in the same axial plane and are not components of a single indication. In addition, a review of the 1985 pre-service inspection indicated that small dings were located in the area of the crack indications. In alloy 600 thermally treated tubing small ding indications are associated with local conductivity changes after the first cycle of operation. As a result there is a change in the bobbin coil phase angle and the small ding may now resemble a shallow OD flaw, however the estimated depth is zero. Signals in this category areclassified as benign signals (not flaw-like). Since all four steam generators were being inspected at 100% bobbin coil, expansion was not required.

The ODSCC indications in SG-B (R4C 122) and in SG-C (RI 8C1 16) were assessed with regard to the need for in situ testing. The population of indications was bounded by Crack 1 in tube R4C 122 in SG-B (Figure 1). None of the ODSCC indications required in-situ testing.

SG-B, R4C122 Three indication of axial ODSCC were confirmed in R4C122 in the free span above the flow distribution baffle and below the first quatrefoil tube support plate. There are three separate cracks that were not axially aligned and have significant un-degraded ligaments separating them.

During the inspection to confirm the axial ODSCC indication in SG-B R4C 122, the two additional, extremely small indications of axial ODSCC were detected in the same tube approximately 6 inches above the indication detected with the bobbin probe. No reportable bobbin signal was detected at these locations although benign signals at these locations have been observed since the pre-service inspection.

Crack 1, with a length of 0.52 inch and a maximum depth of 77% TW, clearly bounds Cracks 2 and 3, which have both shorter length and shallower depths (see Table 1). Using the known material properties for R4C 122, the predicted burst pressure at 95% probability/5 0% confidence for the limiting indication is 4710 psid, which exceeds the 3APNOP pressure differential for Seabrook of 3759 psid.

The voltage threshold (VL-THR) for leak testing for ODSCC cracks is given as 1.OV in OR1 5 Degradation Assessment. Similarly, the voltage threshold (VcRIT) for significant SLB leakage is given as 2.5V for ODSCC in the ORI5 Degradation Assessment. The maximum voltage for this indication is 0.96V; 15

therefore, leak testing was not required and there is no significant potential for SLB leakage from this indication.

The indications in tube R4C122 meet the CM criteria for leak and burst.

SG-C, R18Cl16 A single indication of axial ODSCC was confirmed in conjunction with a dent at the top TSP. The length of the crack is 0.22 inch and its maximum plus point voltage is 0.89V. Depth sizing according to ETSS 128432 yielded a maximum depth of 76%TW. Using the actual material properties for tube R18C 116 in SG-C, a 100% throughwall ODSCC crack of 0.4 inch length is predicted to have a burst pressure of 4342 psid. The 3APNOP pressure differential for Seabrook is 3759 psid. Therefore, this crack does not challenge the CM criteria for burst.

The voltage threshold (VL-THR) for leak testing for ODSCC cracks is given as 1.OV in the ORI 5 Degradation Assessment. Similarly, the voltage threshold (VcRIT) for significant SLB leakage is given as 2.5V for ODSCC in the ORI 5 Degradation Assessment. The maximum voltage for this indication is 0.89V; therefore, leak testing was not required and there is no significant potential for SLB leakage from this indication.

This crack indication meets the CM criteria for leak and burst.
