ENCLOSURE 1 PRAIRIE ISLAND NUCLEAR GENERATING PLANT - UNIT 1 2018 STEAM GENERATOR TUBE INSPECTION REPORT In accordance with Prairie Island Nuclear Generating Plant (PINGP), Unit 1 Technical Specification (TS) 5.6.7, Northern States Power Company, a Minnesota corporation, doing business as Xcel Energy (hereafter NSPM), hereby submits this report of steam generator tube inspections performed during the 2018 refueling and maintenance outage for Unit 1 (1R31). This report is a revision of the report previously submitted under in NSPM letter L-PI-19-015, dated April 18, 2019, (NRC ADAMS Accession Number ML19108A291) and incorporates revised reporting guidance of PINGP TS 5.6.7, which the NRC approved with PINGP Unit 1 and Unit 2 license amendments 241 and 229, respectively, by {{letter dated|date=November 1, 2022|text=letter dated November 1, 2022}}. (NRC ADAMS Accession Number ML22300A223)
PINGP Unit 1 has two Framatome Model 56/19 Replacement Steam Generators (RSGs)
(see Figure 1 - Steam Generator Schematic) with approximately 5,600 square meters of heat transfer area utilizing tubes with 19 millimeter outside diameter. Each RSG has 4,868 thermally-treated Alloy 690 u-tubes manufactured by Sandvik which have an outside diameter of 0.750 inch and a nominal wall thickness of 0.043 inch. The tubes are configured in a square pitch of 1.0425 inches with 55 rows and 114 columns (see Figure 2).
The tube u-bends vary in radius from 2.7000 inches for a row 1 tube to 58.9950 inches for a row 55 tube. The tubes vary in length from 738.16 inches for row 1 tubes to 923.04 inches for row 55 tubes. Row 1 through row 9 tubes were subject to stress relieving following the bending process using the thermal treatment process for an additional 2 hour minimum soak time. The tubes were hydraulically expanded at each end for the full depth of the tubesheet with the expansion transition being between 0.079 inches and 0.236 inches below the secondary tubesheet face.
The tubesheet is low alloy steel 21.46 inches thick with alloys 82 and 182 cladding 0.375 inches thick for an overall thickness of 21.835 inches. The tubes are supported by eight tube support plates (TSPs) and five anti-vibration bars (AVBs) intersecting tubes between 1, 3, 5, 7 and 9 times (see Figure 3). There is one straight bar that intersects all rows at the center of each bend, two 57 degree bars that intersect rows 13 through 55 and two 14 degree bars that intersect rows 25 through 55. In addition, there are 24 peripheral tubes with nine staples (one at each AVB location) that carry the entire load of the complete AVB assembly. All TSPs are constructed from Type 410 stainless steel. The TSPs have a minimum thickness of 1.18 inch and have quatrefoil-shaped holes through which the tubes pass. The AVBs are constructed from Type 405 stainless steel and are rectangular in cross section (nominally 0.5 inch by 0.3 inch).
Each RSG is equipped with a Loose Parts Trapping Systems (LPTS), which is composed of screens at the top of the downcomer and at the top of the primary separators (cyclones).
These screens (0.14 inch square mesh formed from 0.031 inch diameter wire), prevent foreign material from entering the steam generator tube area from the main feedwater and auxiliary feedwater systems (see Figure 3).

Figure 3 LPP&#xa3;RMOST TSP The original PINGP Unit 1 Westinghouse Model 51 Steam Generators (SGs) were replaced during the 2004 refueling outage after 25.73 effective full power years (EFPY) of operation.
During the 2006 refueling outage the first inservice inspection (100% full length bobbin) was conducted on the RSGs after accumulating the initial 1.36 EFPY of RSG operation.
Based on the lack of a definitive root cause for TSP wear and only a single cycle growth rate trend for both AVB and TSP wear identified during 1R24, NSPM conservatively elected to inspect the RSGs during 1R25 (2008 refueling outage) after an additional 1.62 EFPY of RSG operation (2.98 RSG cumulative EFPY). Based on the inspection results of both 1R24 and 1R25, NSPM elected to skip two inspections (1R26 and 1R27; 2009 and 2011 refueling outages, respectively) and perform an inspection of the RSGs during 1R28 (2012 refueling outage) after an additional 4.17 EFPY of RSG operation (7.15 RSG cumulative EFPY). Based on the inspection results of 1R28, NSPM elected to skip two additional inspections (1R29 and 1R30; 2014 and 2016 refueling outages, respectively) and perform an inspection of the RSGs during 1R31 (2018 refueling outage) after an additional 5.17 EFPY of RSG operation (12.32 RSG cumulative EFPY).
There was no operational leakage reported during this operating interval. The nominal THOT during the inspection interval was 590.5 degrees F. There were no Degradation Assessment defined sub-populations of tubes with increased degradation susceptibility.
There were no deviations taken from Mandatory and/or Needed (Shall) requirements important to tube integrity from the Electric Power Research Institute (EPRI) Guidelines referenced by Nuclear Energy Institute (NEI) 97-06 since the last inspection.
Italicized text represents technical specification excerpts. Each excerpt is followed by the appropriate information intended to address each specific requirement and includes additional details based on benchmarking previous NOTE:        submittals, Staff requests for additional information of peer Licensees, and EPRI Tube Integrity Assessment Guidelines reporting requirements. A legend of codes and field names is included at the end of the report.
5.6.7 Steam Generator Tube Inspection Report A report shall be submitted within 180 days after the initial entry into MODE 4 following completion of an inspection performed in accordance with the Specification 5.5.8, Steam Generator (SG) Program.

The X-Probe' deployed contained both a standard bobbin coil and a 16 coil array of transmit/receive coils.
The scope of inspections is provided as a percentage of the open tubes (or plugs) followed by the total number of tests parenthetically (where practical).
No tubes were plugged during the RSG manufacturing or prior to service.
Six tubes were plugged in SG 11 and seven tubes were plugged in SG 12 during previous inspections (1R24, 1R25 and 1R28).
The Row 7 through 55 inspections were completed from both legs (either hot or cold) over the full length (F/L) of each tube (TEHTEC or TECTEH).
Row 1 and 2 bobbin inspections were performed using various extents (08CTEH, 08HTEC, 07HTEC or AV5TEH and AV5TEC).
Post tube plugging visual inspections were conducted by Engineering to validate the tube plug location and proper insertion.
Inspections of the upper internals included the visual inspections of all bolted closures (manways and camera ports), Feedwater Ring (including J-tubes and antistratification (helix) device), Primary Separators (cyclones) Loose Parts Trapping System (LPTS) screens, Downcomer LPTS screens and wrapper position per NRC Generic Letter 97-06 Page 5 of 39

and Prairie Island Unit 1 56/19 Replacement Steam Generator Operation and Maintenance Manual.
Tube lane and periphery of the tube bundle inspected using a camera transport system.
Random fiber-optic inspection of one out of every six columns.
Foreign Object Search and Retrieval of possible loose part (PLP) indications for evaluation and possible removal based on eddy current results (SG 11 only - no PLPs detected in SG 12).
: b. The nondestructive examination techniques utilized for tubes with increased degradation susceptibility, PINGP does not have any specifically identified tubing areas with an increased degradation susceptibility. This fact notwithstanding, as described in Table 1 above, the X-Probe' was utilized on 100% of the tubing full length (from tube end to tube end) except for portions of rows 1 through 5 u-bends.
: c. For each degradation mechanism found:
: 1. The nondestructive examination techniques utilized; Primary Side Inspections:
AVB wear and TSP wear were the only degradation mechanisms found in both SGs during 1R31. The findings of the 1R31 steam generator examination are bounded by the through wall depth behavior projected in the 1R28 operational assessment. Specifically, the deepest %TW sizing of any AVB wear indication by either bobbin or array probe observed during U1R31 was measured at 27% TW. This indication in SG12 tube R42C54 is considerably less than the worst case projected AVB support wear indication of 33%TW from the U1R28 Operational Assessment (OA). Additionally, the deepest %TW sizing of any TSP wear indication by either bobbin or array probe observed during U1R31 was measured at 22% TW. This indication in SG11 tube R47C87 is considerably less than the worst case projected TSP wear indication of 34%TW from the U1R28 OA. In addition to none of AVB or TSP wear indications approaching the condition monitoring (CM) limit, the Upper 95th growth rates from 1R31 have decreased slightly for AVB wear and increased slightly for TSP wear as compared to 1R28 and the actual number of indications reported in 1R31 is less than the projected number of indications in the 1R28 operational assessment.
Table 2 and the notes that follow, provide the Electric Power Research Institute (EPRI)
Examination Technique Specification Sheet (ETSS) (techniques) utilized during 1R31 for existing and potential degradation.

Each listed technique was site validated for both detection and sizing except for PLP wear with the Bobbin probe which utilized the above listed technique for detection while sizing would have been based on the X-Probe' and/or +Point' had PLP wear been detected. In addition, bobbin ETSSs 96010.1 Rev. 7, 24013.1 Rev. 2 and 96007.1 Rev.
12 were site validated for use on non-degradation (MBMs, DNGs, PDSs and cold laps).

: 2. The location, orientation (if linear), measured size (if available), and voltage response for each indication. For tube wear at support structures less than 20 percent through-wall, only the total number of indications needs to be reported; Tables 3 and 4 provide the location, orientation and measured size of each reported AVB wear indication in each steam generator respectively for the degradation found during 1R31. All the tubes in these two tables were returned to service.
Tables 5 and 6 provide the location, orientation and measured size of each reported TSP wear indication in each steam generator respectively for the degradation found during 1R31. All the tubes in these two tables were returned to service.
Tables 7 and 8 provide the location, orientation and measured sizes of AVB and TSP wear indications in each steam generator respectively for tubes preventively plugged during 1R31. The preventive tube plugging criteria implemented during 1R31 was any wear Page 7 of 39

indication greater than or equal to 21% through wall as measured by either the bobbin or array coil.
Within Tables 4 through 6, sixteen tubes with a UTIL2 NCA code were detected by the bobbin coil and not confirmed by the array coil. Within Tables 3 through 8, twelve tubes (with 21 indication locations) were reported with multiple VOL calls at the same ROW/COL/LOC/PROBE which would confirm indications of double sided AVB wear or multiple wear location sites on multiple land contact points of a single Quatrefoil TSP.

A description of the condition monitoring assessment and results, including the margin to the tube integrity performance criteria and comparison with the margin predicted to exist at the inspection by the previous forward-looking tube integrity assessment; and The deepest AVB wear indication reported during 1R31 was 27%TW as reported from the bobbin probe and confirmed as flat wear with the X-Probe'.

(CM) limit (probabilistically determined, using Monte Carlo simulations to apply tube material, relation, and ETSS depth uncertainties at 0.95 probability and 50% confidence level (95/50)) for flat (uniformly deep) AVB wear is 50%TW with the bobbin coil, which slightly bounds indications measured by the array coil. As the deepest indication is of lesser depth than the CM limit, CM is satisfied.
The deepest TSP wear indication reported during 1R31 was 22%TW as reported from the bobbin probe and confirmed as tapered wear with the X-Probe'. The tapered wear CM limit (probabilistically determined, using Monte Carlo simulations to apply tube material, relation, and ETSS depth uncertainties at 0.95 probability and 50% confidence level (95/50)) for TSP wear is 44%TW with the bobbin coil, which slightly bounds indications measured by the array coil. As the deepest indication is of lesser depth than the CM limit, CM is satisfied.
Visual inspections were performed of the SG channel head bowl in both SGs. These inspections are performed based on industry operating experience and guideline requirements. Visual inspections of the SG hot leg and cold leg divider plate, inclusive of the entire divider plate to channel head weld and all visible clad surfaces, were performed in accordance with the latest revision of Westinghouse NSAL-12-1. This inspection was performed using the SG manway channel head bowl cameras. Satisfactory inspection results were observed in both SGs with no indications of corrosion or cladding damage observed. Further, all previously installed tube plugs were also visually inspected by remote video camera from the primary side in each SG. The inspection results were satisfactory and showed no indication of tube plug leakage or failure.
: 4. The number of tubes plugged during the inspection outage.
Table 9 provides the number of tubes plugged during 1R31.

: d. An analysis summary of the tube integrity conditions predicted to exist at the next scheduled inspection (the forward-looking tube integrity assessment) relative to the applicable performance criteria, including the analysis methodology, inputs, and results; Additionally, an operational assessment (OA) was performed that provides reasonable assurance that the performance criteria will not be exceeded until the next planned SG inspection.
The OA predicts a projected depth of:
* 37% for the largest AVB wear indication returned to service,
* 48% for the largest TSP wear indication returned to service, Page 37 of 39

all based on the array coil after an 8.0 EFPY operating interval. Since the largest indication returning to service is greater than the 95th percentile detection threshold for the inspection for both AVB and TSP wear, this conclusion also applies to the assumed undetected indications. The OA also concludes that the structural and leakage integrity performance criteria will be maintained for both a 3- and 4-cycle inspection interval for all degradation mechanisms observed.
The OA calculations are developed using the computer code Single Flaw Model (SFM)
Version 2.2, wherein the burst pressure of projected flaws is determined through the Monte Carlo simulation method described in the EPRI Steam Generator Integrity Assessment Guideline, Rev. 4. Wear projections use the degradation growth normal distribution (AVB only) and beta distributions along with the single largest growth rate observed in both existing and new indications during U1R31. The OA assessment considers 95th percentile 50% confidence level contributions from depth, relation, material and growth in the reduction in tube burst pressure. Undetected flaws are considered in the OA with an assumed depth equal to the 95th percentile using MAPOD software with EPRI ETSS specific voltage-depth correlation and bounding site-specific noise measurements from the current inspection inputs.

: f. The results of any SG secondary side inspections.
Upper Bundle - Minor downcomer LPTS screen grid degradation, on two screen segments, was discovered during 1R30 and dispositioned in the CAP program for one cycle operation without repair. During 1R31 one additional grid with degradation was discovered. All three degraded grids were subsequently replaced during 1R31.
Top-of-Tubesheet - During post sludge lancing and post eddy current FOSAR inspections, no tube degradation was observed that was associated with foreign objects visually observed or eddy current PLP indications recorded.
A top of tubesheet deposit cleaning process was performed in all SGs during Prairie Island U1R31. There are two main purposes of the cleaning process. The first is to remove hardened deposits that tend to form at the top of the tubesheet and the second is to force and filter out any loose parts or foreign objects that have migrated to the SG secondary side during operation. The mass of deposit material and debris removed by the top of tubesheet cleaning process was 12.0 lbs. in SG11 and 13.0 lbs. in SG12. Review of the system in-line filters was performed following the tubesheet cleaning process. This confirmed that the cleaning process was successful at removing a very small number of foreign objects and agglomerated deposit material from the RSG secondary side. The Page 38 of 39

subsequent secondary side visual inspections showed the tubesheet to be essentially free of deposits with only limited hard sludge piles. Hard sludge piles spanning several tubes were observed in the RSGs including SG11 near hot leg columns 42 and 54, SG12 hot leg columns 48 and 54 and SG12 cold leg column 36.
