20 percent of the cold leg TTS from 6 inches above to 3 inches below the TTS (SG A) NOTE 1

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 2R21 inspection consisted of a 100 percent full length bobbin probe examination of the in-service 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 (0.048 inch) which reduces the inside diameter of the sleeve 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.

Currently, there are twenty-eight in-service tubes in Rows 3 and 4 with hot leg tubesheet sleeves installed. The straight length section of these tubes above the tubesheet sleeve will be examined with 0.630 inch wide groove bobbin probe in future outages when applying GL 95-05 requirements.

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

NOTE 1 - For those tube locations where the expansion (EXP) 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 - 2R21 Steam Generator 180 Day Report 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 2R21, 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 channelhead drain line was performed in each hot and cold leg channelhead to meet the requirements of Westinghouse NSAL 12-1 (R1), "Steam Generator Channel Head Degradation". Included in this examination was (a) the divider plate to stub runner weld, (b) the tubesheet to stub runner weld, (c) the divider plate to channelhead weld (d) channelhead to tubesheet weld and (e) the entire clad surface of the channelhead 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 channelhead videos showed no change in this area of discoloration. The visual examination of this area in 2R21 showed no changes in appearance from that reported in 2R20. This area will continue to be visually examined each outage the primary manway covers are removed for an inspection.

Secondary Side Visual Examinations:

Foreign Object Search and Retrieval (FOSAR) - A visual inspection of the secondary side tubesheet face, annulus and tube lane was performed during 2R21 in all three steam generators.

2RCS-SG21A - Three metallic foreign objects (small wire bristles) were observed on the top of the tubesheet. No tube wear was detected as a result of these objects. Two of the three wire bristles were removed from the SG. An evaluation was performed for the remaining wire bristle to remain in the SG until the next operating cycle.

2RCS-SG21B - No foreign material was observed.

2RCS-SG21C - Three non-metallic foreign objects (sludge rock, other two not positively identified) were observed on the top of the tubesheet. No tube wear was detected as a result of these objects. One of the three objects were removed from the SG. Sludge rocks are not considered foreign material as they are indigenous to the operation of the component.

The foreign material left in the SGs will be re-inspected during 2R22.

Possible Loose Part Indications - For those tube locations where possible loose part indications were reported during the 2R21 eddy current examinations and no visual inspections were performed at those particular tube locations, the +Point probe was used to verify that no degradation or tube wall wear was present. These tubes remained in service.

Unit #2 - 2R21 Steam Generator 180 Day Report TS 5.6.6.2.1.b Degradation mechanisms found:

The following degradation mechanisms were reported during 2R21:

Axial ODSCC at non-dented TSP intersections

Axial ODSCC in the hot leg sludge pile freespan regions

Axial ODSCC at the expansion transition regions

Circumferential ODSCC at the hot leg TTS expansion transitions

Circumferential ODSCC at free-span dings

Axial ODSCC at 1st hot leg TSP (Flow distribution baffle)

Wear at AVB intersections

Wear at 1st hot leg TSP (Flow distribution baffle)

Historical foreign object induced wear

Historical freespan volumetric indications

Cold Leg Thinning One tube, Row 40 Column 71 in 2RCS-SG21A, was reported to contain a 25% through wall (TW) wear indication at the 2nd cold leg support plate. This degradation mode is commonly referred to as cold leg thinning.

Since this indication was initially reported by the bobbin probe, no expansion of the inspection scope was required by virtue of the bobbin probe inspection scope already being 100% of the in-service tubes.

This type of indication is not new to the nuclear industry, however, it is the first time reported in the BVPS Unit 2 SGs. Cold leg thinning was prevalent in the older style Model 51 SGs such as the original Unit 1 SGs.

This degradation mechanism has been included in the Cycle 22 SG Operational Assessment which provides final documentation that supports a full cycle (525 EFPD) of operation. This tube will remain in-service for Cycle 22 as the wear indication depth is below the Tech Spec repair criteria of 40%TW.

This indication was entered in the sites corrective action process.

TS 5.6.6.2.1.c Nondestructive examination techniques utilized for each degradation mechanism:

For the degradation mechanisms observed during 2R21, the bobbin coil probe was used as the primary method of detection except at or below TTS and in Row 1 and 2 U-bends 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 2R21 examination techniques were qualified, for detection and sizing (as applicable) of the existing and potential degradation mechanisms listed in the 2R21 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 2R21 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."

Unit #2 - 2R21 Steam Generator 180 Day Report

The examination techniques utilized during 2R21 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 2R21 degradation assessment.

Axial ODSCC in the U-bend region is limited to Row 3 through Row 9 due to the bending technique used for those tube locations.

Per the Technical Specifications, the +Point probe is required to inspect the nickel banded area of the lower tubesheet sleeve joint. The Ghent Version 2 probe, which includes a +Point probe in the design, was used to inspect 100 percent of the hot leg tubesheet sleeves.

Unit #2 - 2R21 Steam Generator 180 Day Report TS 5.6.6.2.1.d Location, orientation (if linear), and measured sizes (if available) of service-induced indications:

The 2R21 SG Examination Results section (Page 13) 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, DSI, 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.

TS 5.6.6.2.1.e Number of tubes plugged or repaired during the inspection outage for each degradation mechanism:

The following tables list the number of tubes plugged or repaired for each existing degradation mechanism reported during 2R21. This is the sixth consecutive outage where the alternate repair criteria of GL 95-05 have been implemented.

For the following Tables:

The Hot Leg Sludge Pile column includes indications located above the top-of-tubesheet (greater than 0.00 inches).

The Hot Leg Expansion Transition (Exp Trans) column includes indications located at or below the top-of-tubesheet (0.00 inch or negative measurement).

Circumferential indications recorded above the top-of-tubesheet are still within the expansion transition region of the tube.

Condition Monitoring

All tubes were shown to satisfy the structural and leakage integrity performance criteria at 2R21.

The relative severity levels of the degradation observed during 2R21 were judged to be consistent with or bounded by the levels associated with previous outage inspection results. Based on the indications observed during 2R21, the SG tubing is expected to meet all operational, structural and leakage integrity requirements at End-of Cycle 22. None of the indications reported during 2R21 represented a leakage potential at postulated main steam line break conditions.

Tube Pulls

No tubes were pulled (removed) from the SG's during 2R21.

In-Situ Pressure Testing

Three tubes were in-situ pressure tested during 2R21. All tubes satisfied the structural and leakage performance criteria with no leak or burst.
