Unit #2 - 2R24 Steam Generator 180 Day Report Page 3 of 29 Per Technical Specification 5.6.6.2.1.a through 5.6.6.2.1.f, the following information is to be submitted to the NRC:

TS 5.6.6.2.1.a The scope of inspections performed on each SG:

Primary Side:

Bobbin Coil Probe (0.720 inch diameter probe utilized unless stated otherwise) 100 percent of the inservice tubes, full length, tube end to tube end, (except Row 1 through 4 U-bend regions as noted below) in non-sleeved tubes per Generic Letter (GL) 95-05, "Voltage-Based Repair Criteria for Westinghouse Steam Generator Tubes Affected by Outside Diameter Stress Corrosion Cracking," dated August 3, 1995 100 percent of the inservice tubes, from the hot leg tube end to the 8th hot leg TSP (straight length) in non-sleeved tubes in Rows 1 through 4 100 percent of the inservice tubes, from the cold leg tube end to the 8th cold leg TSP (straight length) in sleeved and non-sleeved tubes in Rows 1 through 4 100 percent of the inservice tubes, from the cold leg tube end to the top of the tubesheet sleeve on the hot leg side in sleeved tubes Rows 5 and higher 100 percent of the inservice tubes, from the top hot leg TSP (8th) to the top cold TSP (7th) in Row 3 and 4 U-bend regions using a 0.700 inch probe 100 percent of the hot leg sleeved tubes in Rows 3 and 4 from the top of the sleeve to the 8th hot leg TSP using a 0.630 inch wide groove probe

+POINT Probe (unless stated otherwise) 100 percent of Row 1 and 2 U-bend regions 100 percent of the hot leg TTS (from 6 inches above the TTS to 3 inches below the TTS) in non-sleeved tubes NOTE 1 100 percent of the cold leg TTS (from 6 inches above the TTS to 3 inches below the TTS) in non-sleeved cold leg tubes NOTE 1 100 percent of TSP DSI/DNI indications with a bobbin coil voltage > 2.0 volts 100 percent of TSP DSI indications with a bobbin coil voltage > 1.0 volt 100 percent of TSP DSI indications regardless of voltage size at TSP 01H/01C and TSP 02C/03C 100 percent of TSP mix residual signals < 55 degrees and > 1.25 volts 100 percent of TSP mix residual signals > 2.0 volts 100 percent of dented hot and cold leg TSPs > 5.0 volts 100 percent of dents > 2.0 but < 5.0 volts at the 1st through 8th hot leg TSPs 100 percent of dents located at AVB intersections (+/- 1 inch of AVB centerline) 100 percent of new AVB wear signals plus any previous wear with cycle growth > 6 percent 100 percent of freespan dings (All reported voltages) 100 percent of Row 3 through 10 U-bend regions in all SGs 100 percent of BLG and EXP signals in the hot leg tubesheet below the F* distance but above the tubesheet neutral axis 100 percent of BLG and EXP signals above the cold leg TTS 100 percent of bobbin "I-codes", such as freespan differential signals meeting the change criteria (Change criteria: phase rotation > 10 degrees and/or voltage amplitude > 0.5 volts)

Unit #2 - 2R24 Steam Generator 180 Day Report Page 4 of 29 100 percent of freespan signals not resolved as MBMs or without a historical review 100 percent of Westinghouse Alloy 800 tubesheet sleeves from 3 inches above the sleeve (STH+3") to 4 inches below the sleeve (SBH-4").

100 percent of nickel banded region in lower tubesheet joints of Westinghouse Alloy 800 tubesheet sleeves using a Ghent Version 2 probe Proactive examination of a representative sample of DSI indications < 2.0 volts previously confirmed to contain axial ODSCC 25 percent of TSP mix residual signals > 1.5 volts but < 2.0 volts Bounding of historical plugged tubes due to foreign object wear at the TTS and newly reported PLP signals In accordance with the guidance provided by GL 95-05, the 2R24 inspection consisted of a 100 percent full length bobbin probe examination of the inservice non-sleeved tubes in all three SGs.

All hot and cold leg TSP intersections were inspected using a 0.720 inch diameter bobbin probe.

The only exception to the use of the 0.720 inch diameter bobbin probe for GL 95-05 applications is the straight length section above the Alloy 800 hot leg tubesheet sleeves in Rows 3 and 4. Due to the thickness of the hot leg tubesheet sleeve wall which reduces the inside diameter of the tube and the inability of a 0.720 inch diameter bobbin probe to traverse the U-bend region of Rows 3 and 4, a 0.630 inch diameter wide groove bobbin probe was used to inspect the straight length section of the Row 3 and 4 tubes above the hot leg tubesheet sleeve including the TSP intersections.

GL 95-05 states that smaller or larger diameter probes can be used to inspect tubes when it is impractical to utilize a nominal-size probe provided that the probes and procedures have been demonstrated to give an equivalent voltage response and detection capability when compared to the nominal (in this case 0.720 inch) probe. Probe equivalency testing between the nominal 0.720 inch bobbin probe and 0.630 inch wide-groove bobbin probe was performed during 2R21.

It was successfully demonstrated that the 0.630 inch wide-groove probe met the equivalency requirements of Appendix H of the EPRI Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines: Revision 8.

An eddy current scope expansion was not required in 2R24.

+POINT is a trademark or registered trademark of Zetec, Inc.

NOTE 1 - For those tube locations where the lower roll transition is located deeper into the tubesheet, the inspection distance into the tubesheet was adjusted to 5 inches below the top of the tubesheet to ensure adequate inspection coverage of the F* distance.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 5 of 29 Primary Side Visual Examinations Tube Plugs - 100 percent of the tube plugs are visually examined (as-found and as-left condition) each time the primary side is opened for a scheduled inspection. This visual examination is to document the condition of the hot and cold leg tube plugs. This process also includes tube plug accountability. During 2R24, as well as in prior outages, the examinations verified that the correct number of tube plugs were present and in the proper tube locations. Installed tube plugs were examined and determined to be acceptable. No signs of degradation were observed.

Westinghouse Plug-in-Plug (PIP) - There are 9 hot leg and 9 cold leg tube locations (SG A - 4; SG B - 2; SG C - 3) which contain Alloy 600 plugs repaired with the Westinghouse PIP technique.

These locations are visually examined each outage to assess the condition of the tack weld which holds the PIP in place. No sign of cracking was reported in any of the eighteen PIP tack welds.

All tube plugs were accounted for and all were verified to be in their proper location.

Westinghouse Nuclear Safety Advisory Letter (NSAL) 12-1 (Revision 1) - A remote visual inspection of the area around the channel head drain line was performed in each hot and cold leg channel head to meet the requirements of Westinghouse NSAL 12-1 (R1), "Steam Generator Channel Head Degradation". Included in this examination was the:

Divider plate-to-channel head weld Divider plate-to-stub runner weld Tubesheet-to-channel head Z-seam area Tubesheet cladding The entire clad surface of the channel head bowl This inspection looked for evidence of gross defects such as indications in welds, missing weld filler material, a breach in the weld metal, and unusual discoloration of the weld metal and/or cladding imperfections. All inspections were determined to be acceptable. No sign of cladding breach, cracking, missing filler metal was observed. During 2R20, in the cold leg of SG C, a small area of discoloration (non-rust color) was observed approximately 1 foot from the divider plate. Subsequent review of previous channel head videos showed no change in this area of discoloration. The visual examination of this area in 2R24 showed no changes in appearance from that reported in 2R20, 2R21, 2R22, and 2R23. This area will continue to be visually examined each outage the primary manway covers are removed for an inspection.

Secondary Side Visual Examinations:

Secondary side tubesheet cleaning and visual inspections were completed during 2R24. The inspections are summarized below:

Sludge lancing in all three SGs Post sludge lancing cleanliness inspection in all three SGs Post sludge lancing FOSAR in all three SGs in the following areas:

o Hot leg and cold leg annulus region o Hot leg and cold leg peripheral tubes o Tube lane and tube lane peripheral tubes o Blowdown pipe and supports o Tube lane blocking devices o In-bundle PLP locations from eddy current testing In-bundle visual inspections of selected hot leg and cold columns from the tube lane in all three SGs Feedring and upper steam drum inspections in SG A

Unit #2 - 2R24 Steam Generator 180 Day Report Page 6 of 29 TS 5.6.6.2.1.b The nondestructive examination techniques utilized for tubes with increased degradation susceptibility:

No degradation mechanism sub populations were used for the purposes of Operational Assessment calculations. The BVPS Unit 2 SGs have various existing and potential degradation mechanisms, which are inspected for using qualified techniques. The techniques utilized are described in the TS 5.6.6.2.1.c.1 section.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 7 of 29 TS 5.6.6.2.1.c For each degradation mechanism found:

1. The nondestructive examination techniques utilized:

For the degradation mechanisms observed during 2R24, the bobbin coil probe was used as the primary method of detection except at or below TTS, in Row 1 and 2 U-bends, detecting circumferential ODSCC in freespan dings, and detection of circumferential PWSCC in Rows 3-10 where the bobbin probe is not qualified. In these areas, the +POINT probe was employed. The

+POINT probe is also used to re-examine any ambiguous bobbin coil signals (I-codes) that were reported.

The 2R24 examination techniques were qualified, for detection and sizing (as applicable) of the existing and potential degradation mechanisms listed in the 2R24 Degradation Assessment. This qualification was in accordance with Appendices H and I of the EPRI, "Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines:

Revision 8".

Site-specific ETSS's are developed prior to each steam generator inspection for each existing and potential degradation mechanism identified in the 2R24 Degradation Assessment. The site-specific ETSS's are developed in accordance with Appendices H and I of the EPRI, "Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines: Revision 8."

The examination techniques utilized during 2R24 are considered "Site Validated" as defined in the EPRI, "Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines: Revision 8," for each existing and potential degradation mechanism listed in the 2R24 Degradation Assessment.

(1) Westinghouse supplemental screening criterion for the detection of axial PWSCC at dented TSPs with dents less than 2 volts. The supplemental screening criterion establishes the phase angle and voltage amplitude signal responses for when diagnostic +POINT probe inspections are required. More information provided in the RAI 1 response dated October 21, 2022 (ML22304A213).

(2) Application of ETSS 21998.1 may include use of a standard calibration using 0.063-inch diameter flat bottom holes or flat bottom holes of the ASME Code standard, based on observed flaw dimensions. ETSSs 27901.3, 27901.6, 27902.3, 27902.6, 27903.3, 27903.6, 27904.3, 27904.6, 27905.3, 27905.6, 27906.3 or 27906.6 may be applied as necessary based on the specific wear scar shape observed.

(3) The +POINT probe is used to inspect all areas of the sleeve and parent tube behind the sleeve, except for the lower tubesheet joint behind the nickel band region.

(4) Use of a combination (Combo) probe that contains a +POINT probe and Ghent Version 2 probe may be used. The Ghent Version 2 probe is used to inspect the lower tubesheet joint adjacent to the nickel band sleeve. Use of a combination (Combo) probe that contains +POINT coils and Ghent Version 2 coils may be used.

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:

The 2R24 Examination Results section (Page 29 and Attachments A, B, and C) lists information that includes the location, orientation and measured sizes of service-induced indications. Further explanation of the information provided in the results section is given below:

Bobbin probe indications reported as "I-codes" (DNI, DTI or NQI) were re-inspected with the

+POINT probe.

Bobbin probe indications reported as PSI were re-inspected with the +POINT probe. If the

+POINT probe indicated a possible TSP ligament breach existed (CSI), it was further evaluated by the original equipment manufacturer (OEM) engineering group. All ligament breach extents were found to be acceptable for continued plant operation.

New AVB indications reported from the bobbin probe listed as PCT were inspected with the

+POINT probe. If the +POINT probe indicated no crack-like flaws were present within the wear scar, a wear call (WAR) was assigned to the +POINT report.

+POINT indications reported as "I-codes" (SAI, SCI, MAI or MCI) were either (a) removed from service via plugging, (b) left in service by installing hot leg tubesheet sleeves or (c) left in service if the indications qualified under the requirements of GL 95-05.

For hot leg top of tubesheet circumferential indications that could not be sleeved, a stabilizer was installed prior to plug installation.

The use of codes HAI and HCI are for tubes that were de-plugged with the intention to sleeve or return to service with Generic Letter 95-05. These were the historical SAI and SCI calls that caused the tube to be plugged in the first place. The de-plugged tube required inspection after de-plugging for a baseline prior to sleeving and returning the tube back to service. The HAI and HCI (H for historical) calls were to flag the original call.

3. 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:

Condition Monitoring (CM) is the assessment performed on observed indications of tube degradation to confirm that the SG integrity performance criteria embodied in the CM limits have not been violated. CM is a backward-looking evaluation to assess the as-found SG condition to validate that all SG performance criteria have been satisfied throughout the prior operating cycle. The CM limits are derived from the SG performance criteria in accordance with the EPRI SG Integrity Assessment Guidelines. The burst pressure simulation results contained within the CM assessment were calculated with the Westinghouse Single Flaw Model Version 2.5. The tube burst and ligament tearing calculations are consistent with the EPRI SG Degradation Specific Flaw Handbook methodologies.

Based on the BVPS 2R24 inspection results, no tubes contained indications which represented a challenge to structural or leakage integrity and all CM requirements are satisfied.

No indications were required to be in situ pressure tested. However, an in situ pressure test was performed to demonstrate compliance with the condition monitoring structural and leakage integrity performance criteria. Tube R18C26 in SG B contained a mixed mode ODSCC indication at the hot leg tubesheet expansion transition. While the mixed mode flaw screened out of in situ testing, there are no available industry calculational methods for determining the burst and leakage capabilities for a mixed mode flaw. Therefore, in situ testing was performed to satisfy the condition monitoring criteria. The in situ pressure proof and leak testing resulted in no burst and no leakage for any of the test pressures. The highest test pressure achieved was 5400 psi which was associated with the adjusted 3PNOP pressure. The table below contains the flaw sizing parameters for R18C26 in SG B. Eddy current testing was performed following in situ testing; however, there were no appreciable changes to the characteristics of the flaws.

(1) CM performed for the largest maximum depth and largest flaw length of the population treated as one flaw and were in different tubes.

(2) Limiting flaw dimensions were contained in different tubes.

(3) Leakage integrity demonstrated by satisfaction of the in situ pressure test leakage screening voltage limit, 0.50 volt.

(4) The largest TSP axial flaw lengths were 0.15 inch and 0.16 inch. A bounding length of 0.20 inch was used for CM calculations (5) Flaw is located 8.63 inches below the top of tubesheet in the hard rolled region and therefore the flaw cannot burst due to the tubesheet constraint. If treated as a 100% TW freespan crack, the burst potential would be 5570 psi.

Notes:

(1)

The maximum depth inspection result by phase angle sizing slightly exceeds the deterministic projection and is judged to be a result of the flaw phase angle being shifted to higher depths from the effects of the expansion transition and tubesheet material. 100% circumferential flaws are on the order of 3 volts, whereas the 2R24 flaw voltages are 0.25 volts and less.

(2)

Flaw parameter adjusted by the NDE mean sizing regression to compare to the fully probabilistic true size projection to provide a like comparison.

(3)

The as-found NDE parameter exceeded the OA prediction by a small margin which is well within NDE uncertainty and variability. A fully probabilistic OA method had been applied that showed that the upper tail of the parameter distribution is well represented and bounds the reported values, thus meeting the intent of the EPRI guidance.

(4)

Prior OA performed Arithmetic/Monte Carlo method for leakage integrity (ligament tearing pressure, PLig) using total length as SEL and maximum depth.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 18 of 29 TS 5.6.6.2.1.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:

The EPRI SG Integrity Assessment Guidelines provide guidance for methodologies and approaches to performing an Operational Assessment (OA). Typically, the OA is performed with simplified techniques, by fully probabilistic techniques (Monte Carlo), or by a combination of both. The simplified techniques use a worst-case degraded tube approach by determining the single largest flaw that could be present at the beginning of the inspection interval and applying a conservative growth rate (maximum or 95th percentile growth) to project that flaw to the end of the next inspection interval. The fully probabilistic technique projects the entire flaw population to the end of the inspection interval through simulations that apply growth and uncertainty distributions to distributions of flaw size, material property, and burst relation. Both techniques consider flaws that may be undetected and flaws that may initiate during the inspection interval. The methodologies are further defined by the repair strategy for the given degradation mechanism, repair-on-detection or repair based on NDE sizing. The repair on NDE sizing methodologies consider flaws that are left in service based on acceptable flaw sizes that are defined by the technical specifications. The OA for repair on NDE sizing techniques must include NDE uncertainties. Wear at support structures, volumetric wear from foreign material, and cold leg thinning are examples of repair on NDE sizing mechanisms. Stress corrosion cracking degradation are examples of repair on detection mechanisms. NDE sizing uncertainties are not required to be included in repair on detection techniques since all known flaws have been repaired and no known flaws are returned to service that were measured by NDE techniques. Postulated undetected flaws assumed in repair on detection techniques are determined based on true physical flaw dimensions. All OA techniques are performed at 0.95 probability and 50% confidence level (95/50). All OA techniques also account for the 95/50 tube material and burst relation adjustments.

Methodologies in the Cycle 25 OA include:

Worst Case Degraded Tube Simplified Techniques:

o Arithmetic o Mixed Arithmetic/Monte Carlo o Arithmetic Special Case Fully Probabilistic Simplified Techniques The worst-case degraded tube arithmetic OA approach applies a conservative growth allowance, either 95th percentile or maximum flaw growth rate, to the largest flaw left in service or largest potentially undetected flaw at the beginning of cycle (BOC) and compared to the performance criteria with material property and burst relation uncertainties considered. The largest flaw left in service is adjusted for the mean NDE sizing regression and applying the upper 95/50 percentile NDE sizing uncertainty. The end-of-cycle (EOC) flaw length is equal to a physically bounding value (e.g., tube support width) or 95th percentile length of detected flaws for at least the last 2 inspections. This procedure provides a conservative estimate of the lower 95th percentile burst pressure at the end of the inspection interval.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 19 of 29 The mixed arithmetic/Monte Carlo technique is similar to the arithmetic technique, except that the material property and burst relation uncertainties are individually sampled and combined using Monte Carlo simulations. The NDE sizing uncertainty is deterministically derived at the 95/50 value. The Westinghouse SFM computer code is used to perform the Monte Carlo simulations.

The worst-case degraded tube arithmetic special case approach can be used for plug-on-detection mechanisms (i.e., cracking). This method was developed for cases where the 95th percentile flaw size is very large and is only applicable when the number of flaws is small. Section 8.5.2 of the EPRI SG Integrity Assessment guidelines provides further information and justification for this method.

Fully Probabilistic Technique The operational assessment of SCC degradation mechanisms is performed using fully probabilistic methods through application of the Westinghouse Full Bundle Model (FBM) software package. The basic methodology for the fully probabilistic analysis is the same for each degradation mechanism, however, the specific inputs for each mechanism may be different. The fully probabilistic model combines the BOC flaw size distributions with the growth distributions to determine the probability of burst (POB), probability of accident induced leakage (POL), lower 5th percentile burst pressure and 95th percentile accident leak rate at the end of the inspection interval. The results are compared to the SG performance criteria.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 20 of 29 Summary of Results The table below provides a summary of the Cycle 25 OA results for predicted structural and leakage integrity parameters for each degradation mechanism and for each OA methodology used. The table provides the predicted burst pressure, ligament tearing pressure, SLB leak rate, and for fully probabilistic OA methods, the POB and probability of SLB leak (POL) as applicable for the applied OA method. When the predicted burst pressure is 4525 psi or greater, the structural integrity performance criteria for OA is satisfied. Likewise, when the ligament tearing pressure is 2560 psi or greater no leakage at SLB conditions is predicted and therefore the accident induced leakage performance criteria for OA is satisfied. The structural and leakage performance criteria are satisfied for fully probabilistic OA methods when the POB and POL values are each 5% or less. It is noted that additional OA methodologies may have been used as defense-in-depth measures, which are also included in the table. All degradation mechanisms satisfied the structural and leakage performance criteria for all OA methods used.

The OA established that BVPS-2 can operate for at least 1.437 EFPY for the Cycle 25 period without exceeding the SG structural or leakage integrity performance criteria for the observed and presumed flaws from the 2R24 inspection. Degradation mechanisms that are not under the purview of an alternate repair criterion were evaluated for structural (burst) and leakage potential for the projected flaw condition at the end of Cycle 25 using either simplified (deterministic) or fully probabilistic methods, or both. When deterministic OA leakage integrity assessments were performed, the flaw ligament tearing pressures are calculated and the POL is zero when the minimum ligament tearing pressure is satisfied. All degradation mechanisms evaluated through deterministic methods have a zero POL at the limiting accident (SLB) conditions for the projected flaw condition at the end of Cycle

25. For fully probabilistic OA evaluations, the probabilities of burst and leakage for each mechanism were calculated and compared to the 5% performance criterion. For each degradation mechanism evaluated satisfied the POB and leakage 5% performance criterion. The combined accident induced leakage from tube degradation, repair hardware, postulated pre-existing operational leakage, and application of GL 95-05, satisfied the allowable leakage limit for all leakage sources.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 23 of 29 Notes:

(1) The Arithmetic/Monte Carlo OA method for this mechanism refers to the simplified worst-case degraded tube arithmetic method where the uncertainties are combined with Monte Carlo simulations and the NDE uncertainties are applied deterministically at 95/50.

(2) Per WCAP-15919-P a degraded lower tubesheet sleeve joint leaks at 2 x 10-5 gpm per sleeve at SLB conditions. 10 sleeves are assumed to be degraded.

(3) This mechanism is located at the neutral plane of the tubesheet. The constraining effects of the tubesheet eliminates tube burst capability.

(4) The Alloy 800 tubesheet sleeve leakage at SLB conditions is 1.438 x 10-5 gpm per sleeve.

(5) The B&W rolled plug leakage at SLB conditions is 1.354 x 10-6 gpm per plug.

(6) The Arithmetic Special Case method was applied with combining uncertainties through Monte Carlo simulations.

(7) Leakage integrity is demonstrated by comparison of the largest flaw voltage amplitude to the EPRI In Situ Pressure Test Guideline threshold voltage for leak testing value (VTHR-L) for the applicable mechanism. Flaw voltage was less than the VTHR-L value.

Unit #2 - 2R24 Steam Generator 180 Day Report Page 25 of 29 TS 5.6.6.2.1.f The results of any SG secondary side inspections:

Secondary side tubesheet sludge lancing and FOSAR were completed in all SGs in 2R24. Visual inspections and ultrasonic examinations were also completed in SG A in 2R24.

The 2R24 tubesheet sludge lancing removed a total of 90.0 lbs of sludge from the 3 SGs: 29.5 lbs from SG A, 40.5 lbs from SG B, and 20.0 lbs from SG C. Deposit removal amounts have fluctuated from outage to outage but generally have been stable to slightly increasing.

FOSAR of the peripheral annulus region, tube lane, and investigation of new PLP signals in all SGs revealed 7 newly identified metallic objects and 4 legacy objects. The most significant object was found on the cold leg tubesheet of SG A and was a metal rod that measured 18 inch long with a 0.125-inch diameter. This object was first identified during 2R22 (2021) and was visually confirmed to have remained unchanged and did not produce any tube wear or PLP signals. The object was located between Tube Rows 11-12 and Tube Columns 45-59. No tube wear was associated with this object through eddy current testing. The object was unable to be retrieved and remains in SG A. An evaluation was completed to justify leaving the object in the SG. The remaining metallic objects were small bristle wires (7), metal shard (1), weld slag (1), and a 3.5-inch rod (1). Two bristle wires and the 3.5-inch rod were retrieved from the SG. No tube wear was associated with any of these objects. The weld slag was firmly wedged between 2 tubes. All objects not retrieved have been successfully evaluated to remain in the SGs for at least an additional cycle of operation. The table below summarizes the objects:

0.4 No No In addition to FOSAR activities, visual inspections in all SGs were performed of the blowdown pipe elbow weld near the annulus and the blowdown pipe support bracket to tubesheet weld near the center of the SGs. No degradation was found on the blowdown pipes, blowdown pipe elbow tubesheet welds, and the pipe support bracket tubesheet weld.

Visual inspections were also performed on the tube lane blocking devices in all SGs. A tube lane blocking device consists of 4 plates that are fillet welded together to form a box. The front and back plates contain an access hole to allow for sludge lance tooling and visual inspections. The side plates, excluding the first blocking device entering the tube lane, contain windows cutouts to allow for sludge lancing and viewing the hot leg and cold leg tubes. This assembly sits atop and is tack welded to the support blocks which the blowdown pipe passes through. For each blowdown pipe on both sides of the tube lane, there are 5 groupings of tube lane blocking devices. Erosion of these components had been identified in prior inspections with recommendations for monitoring each outage. The 2R24 visual inspections of each set of tube lane blocking devices confirmed active progression of erosion of these components. The visual inspections showed that sufficient weld material is present and other welds were unaffected by the erosion to provide integrity of the blocking devices. The observed degraded conditions of the tube lane blocking devices are not expected to significantly impact or compromise the functionality of the tube lane blocking devices. This condition will continue to be monitored in future outages.

Visual inspection of the SG A steam drum components included a general inspection of the primary and secondary moisture separator components, swirl vanes, riser and downcomer barrels, orifice rings, tangential nozzles, drain pipes, and general area surfaces and other components at the mid-deck plate and lower deck plate regions including the feedwater header and J-nozzles. In addition, the level instrumentation tap holes were inspected for deposits or blockages. The condition of the steam drum internal components is generally good with local areas of minor erosion. Areas of erosion included impingement erosion of feedwater header pipe underneath several J-nozzles on the feedwater header and a primary moisture separator downcomer barrel. Internal erosion at several J nozzle internal pipe penetrations was also observed. The most significant was on J-nozzle #21 where the internal nozzle penetration pipe material was eroded to the extent that the back side of the exterior attachment fillet weld was visible over a short extent when view from inside the feedwater pipe. An evaluation concluded that the condition had not significantly changed over the last 5 cycles from the last inspection and it is expected that the erosion will not significantly progress over the next 6-cycle inspection interval.

Routine ultrasonic (UT) header pipe thickness measures were taken at 9 locations around the ring header and at 4 azimuthal positions at each of the 9 locations (i.e., top, bottom, and sides (2) of the pipe). These measurements showed acceptable pipe thicknesses but with gradual thinning in some areas over time. The SG level instrumentation tap holes exhibited evidence of deposit buildup and scaling inside the pipe from the inner SG pipe penetrations to the instrument isolation valves. The general condition of the level instrument lines was similar to the condition found in SG-B and SG-C that were inspected in 2R23 and 2R22, respectively.
