In accordance with Prairie Island Nuclear Generating Plant (PINGP), Unit 1 Technical Specification 5.6.7, Xcel Energy Nuclear Department submits this report of steam generator tube inspections performed during the 2018 refueling and maintenance outage for Unit 1 (1R31).  
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 5.6.7, Xcel Energy Nuclear Department submits this report of steam generator tube inspections performed during the 2018 refueling and maintenance outage for Unit 1 (1R31).
PINGP Unit 1 has two Framatome Model 56/19 Replacement Steam Generators (RSGs) 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 1). 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 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 2). 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 square mesh formed from 0.031 diameter wire), prevent foreign material from entering the steam generator tube area from the main feedwater and auxiliary feedwater systems (see Figure 2).

The tubesheet is low alloy steel 21.46 inches thick with alloys 82 and 182 cladding 0.375" 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 2). 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.

UPPERMOST TSP Figure 2 The original Westinghouse Model 51 Steam Generators (SGs) were replaced during the 2004 refueling outage after 25. 73 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 (2009 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 (1 R26 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).

* 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).
1 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 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. Degradation mechanisms found, 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.
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.
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.
: c. Nondestructive examination techniques utilized for each degradation mechanism, 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.

: d. Location, orientation (if linear), and measured sizes (if available) of service induced indications, 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 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. Conversely, all VOL calls at the same ROW/COL/LOC/PROBE confirm only single sided wear sites at all the remaining AVB and TSP locations.
A legend of fields and codes with brief explanations is provided at the end of this enclosure for clarification purposes.

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" square mesh formed from 0.031" diameter wire), prevent foreign material from entering the steam generator tube area from the main feedwater and auxiliary feedwater systems (see Figure 2).

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 1 R24, NSPM conservatively elected to inspect the RSGs during 1 R25 (2009 refueling outage) after an additional 1.62 EFPY of RSG operation (2.98 RSG cumulative EFPY). Based on the inspection results of both 1 R24 and 1 R25, NSPM elected to skip two inspections (1 R26 and 1 R27; 2009 and 2011 refueling outages, respectively) and perform an inspection of the RSGs during 1 R28 (2012 refueling outage) after an additional 4.17 EFPY of RSG operation (7.15 RSG cumulative EFPY). Based on the inspection results of 1 R28, NSPM elected to skip two additional inspections (1R29 and 1R30; 2014 and 2016 refueling outages, respectively) and perform an inspection of the RSGs during 1 R31 (2018 refueling outage) after an additional 5.17 EFPY of RSG operation (12.32 RSG cumulative EFPY).

* The X-ProbeŽ 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 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 PLP's detected in SG 12).
Page 5 of 40 b. Degradation mechanisms found, 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. 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.

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. Conversely, all VOL calls at the same ROW/COL/LOC/PROBE confirm only single sided wear sites at all the remaining AVB and TSP locations.

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'. The condition monitoring (CM) limit for 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 CM limit 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.
Additionally, an operation assessment (OA) was performed that provides reasonable assurance that the performance criteria will not be exceeded during the upcoming operating cycles 31, 32 and 33 until the next planned SG inspection.

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 5.6.7, Xcel Energy Nuclear Department submits this report of steam generator tube inspections performed during the 2018 refueling and maintenance outage for Unit 1 (1R31).

PINGP Unit 1 has two Framatome Model 56/19 Replacement Steam Generators (RSGs) 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 1). 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 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> 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 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 2). 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 square mesh formed from 0.031 diameter wire), prevent foreign material from entering the steam generator tube area from the main feedwater and auxiliary feedwater systems (see Figure 2).

UPPERMOST TSP Figure 2 The original Westinghouse Model 51 Steam Generators (SGs) were replaced during the 2004 refueling outage after 25. 73 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 (2009 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 (1 R26 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).

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.

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.

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.

c. Nondestructive examination techniques utilized for each degradation mechanism, 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.

d. Location, orientation (if linear), and measured sizes (if available) of service induced indications, 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 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. Conversely, all VOL calls at the same ROW/COL/LOC/PROBE confirm only single sided wear sites at all the remaining AVB and TSP locations.

A legend of fields and codes with brief explanations is provided at the end of this enclosure for clarification purposes.

e. Number of tubes plugged during the inspection outage for each degradation mechanism, Table 9 provides the number of tubes plugged during 1R31.

TABLE 9 MECHANISM SG 11 SG 12 AVB Wear 0 4 TSP Wear 2 1

f. The number and percentage of tubes plugged to date, and the effective plugging percentage in each steam generator, and Table 10 provides the total number and percentage of tubes plugged to date.

TABLE 10 PLUGGING SG 11 SG 12 TOTAL 8 12 PERCENT 0.16% 0.25%

g. The results of condition monitoring, including the results of tube pulls and in-situ testing.

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'. The condition monitoring (CM) limit for 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 CM limit 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.

Additionally, an operation assessment (OA) was performed that provides reasonable assurance that the performance criteria will not be exceeded during the upcoming operating cycles 31, 32 and 33 until the next planned SG inspection.
