Serial No. 06-060 Page 1 Steam Generator Tube Inspection Millstone Unit 2 (MP2) is a two loop ABB-CE PWR with Babcock and Wilcox (B&W) replacement Steam Generators (SG). Each SG was designed to contain 8523 U-bend thermally treated Inconel 690 tubes. One hot leg tube sheet hole in SG 1 was plugged during construction and the opposing cold leg hole was not drilled, thus SG 1 has 8522 tubes. The tubing is nominally 0.750 inch outside diameter with a 0.0445 inch nominal wall thickness. During replacement SG fabrication, the tubes were installed using a two-step hydraulic expansion process over the full depth of the 21.06 inch thick tubesheet. The tubesheet was drilled on a triangular pitch with 1.0 inch spacing. There are 141 rows and 167 columns in each SG. To minimize small radius U-bends, tubes in rows 1 through 3 were installed using a staggered arrangement. This resulted in the termination of tubes at different locations between the hot and cold legs. For these rows, the tube identification follows the hot leg row/column naming convention.

The tubing is nominally 0.750 inch outside diameter with a 0.0445 inch nominal wall thickness.
Secondary side tube support structures include seven lattice grid supports on the vertical section of the tubes and twelve fan bar assemblies on the U-bend section of the tubes. All lattice grid supports are full supports.
During replacement SG fabrication, the tubes were installed using a two-step hydraulic expansion process over the full depth of the 21.06 inch thick tubesheet.
SG replacement was completed during 2R1 1 (Fall 1992). The new SGs have accrued 7.037 Effective Full Power Years (EFPY) of operation as of the end of Cycle 16 (April 2005). The 910 MW Unit operates with a hot leg temperature of 601 degrees Fahrenheit.

Revision 6; and Millstone Unit 2 Technical Specifications. Performed in SG 1 only, the inspection included a 100% bobbin coil exam and 298 special interest and diagnostic exams utilizing Motorized Rotating Pancake Coil (MRPC) technology. The only indications of degradation recorded were attributed to mechanically induced wear. ECT identified two tubes with nine (9) percent throughwall fan bar wear, unchanged from the 2R14 results. No tubes were removed from service or otherwise repaired.
Performed in SG 1 only, the inspection included a 100% bobbin coil exam and 298 special interest and diagnostic exams utilizing Motorized Rotating Pancake Coil (MRPC) technology.
One hundred percent (100%) of all in-service tubes (8522 tubes) in SG 1 were examined full length with the standard bobbin coil technique. The tubes were examined tube end to tube end (TEC-TEH) from the hot leg channel head.

Enclosure 1 Millstone Unit 2 2005 Steam Generator Tube Inservice Inspection Millstone Power Station Unit 2 Dominion Nuclear Connecticut, Inc. (DNC)

Serial No.06-060 Page 1 Steam Generator Tube Inspection Millstone Unit 2 (MP2) is a two loop ABB-CE PWR with Babcock and Wilcox (B&W) replacement Steam Generators (SG). Each SG was designed to contain 8523 U-bend thermally treated Inconel 690 tubes. One hot leg tube sheet hole in SG 1 was plugged during construction and the opposing cold leg hole was not drilled, thus SG 1 has 8522 tubes. The tubing is nominally 0.750 inch outside diameter with a 0.0445 inch nominal wall thickness. During replacement SG fabrication, the tubes were installed using a two-step hydraulic expansion process over the full depth of the 21.06 inch thick tubesheet. The tubesheet was drilled on a triangular pitch with 1.0 inch spacing. There are 141 rows and 167 columns in each SG. To minimize small radius U-bends, tubes in rows 1 through 3 were installed using a staggered arrangement. This resulted in the termination of tubes at different locations between the hot and cold legs. For these rows, the tube identification follows the hot leg row/column naming convention.

Secondary side tube support structures include seven lattice grid supports on the vertical section of the tubes and twelve fan bar assemblies on the U-bend section of the tubes. All lattice grid supports are full supports.

SG replacement was completed during 2R1 1 (Fall 1992). The new SGs have accrued 7.037 Effective Full Power Years (EFPY) of operation as of the end of Cycle 16 (April 2005). The 910 MW Unit operates with a hot leg temperature of 601 degrees Fahrenheit.

The Millstone Unit 2 SG eddy current testing (ECT), conducted at the end of Cycle 16, was completed on April 25, 2005. The examinations, personnel, and equipment conformed to the requirements of NEI 97-06, rev. 1, Steam Generator Program Guidelines; EPRI Pressurized Water Reactor Steam Generator Examination Guidelines:

Revision 6; and Millstone Unit 2 Technical Specifications. Performed in SG 1 only, the inspection included a 100% bobbin coil exam and 298 special interest and diagnostic exams utilizing Motorized Rotating Pancake Coil (MRPC) technology. The only indications of degradation recorded were attributed to mechanically induced wear. ECT identified two tubes with nine (9) percent throughwall fan bar wear, unchanged from the 2R14 results. No tubes were removed from service or otherwise repaired.

One hundred percent (100%) of all in-service tubes (8522 tubes) in SG 1 were examined full length with the standard bobbin coil technique. The tubes were examined tube end to tube end (TEC-TEH) from the hot leg channel head.

Two hundred ninety-eight (298) tubes were examined with the MRPC plus-point probe; one hundred forty-two (142) hot-leg roll transition exams and one hundred fifty-six (156) special interest and diagnostic examinations. MRPC examination locations are summarized below and in Table 2.

The extent for the roll transition area examination was top of tube sheet hot (TSH) +3/-3 inches. This area was selected based on the historical hot leg sludge pile region as compiled from previous SG 1 and SG 2 (2R13, 2R14, and 2R15) results. The 142 tube

Serial No.06-060 Page 2 locations selected for examination make up fifty percent (50%) of this total sludge region (284 tubes) identified from both SGs. Approximately seventy-four (74%) of the tubes in the sample had previously identified Sludge (SLG) indications in SG 1. SLG indications reported during the current inspection are mapped in Attachment 5. One tube with a historical Partial Tubesheet Expansion (PTE) indication was also examined TSH-TEH.

One hundred and fifty-six (156) tubes were examined at a specific area of interest. The sixty-three (63) preplanned examinations were conducted at locations of previously identified dents, dings, bulges, possible loose parts, over expansions, and fan bar wear.

Ninety-three (93) diagnostic examinations were conducted at locations associated with indications reported during the current inspection. These included dents, dings, bobbin I-codes, possible loose parts, and tubes surrounding possible or known loose parts.

This ECT examination was conducted following five cycles (7.037 EFPY) of operation with the replacement SGs. There were no indications of any corrosion related tube cracking.

ECT reported two (2) tubes with nine (9) percent throughwall (%TW) fan bar wear. The ECT results from 2R14 also reported 9%TW wear on these tubes, thus the wear has not progressed over the past two operating cycles. Additional details on fan bar wear in both SGs are provided in Table 3 and Attachment 6.

One Volumetric Indication (VOL) was reported. This VOL indication has been reported since the June 1997 examination with MRPC. It is believed to be associated with a Manufacturing Buff Mark (MBM) and exhibits no change since first reported. Additional details are provided in Attachment 7.

Twenty-five (25) PLP indications were also reported. These ECT reported indications were grouped in eleven (11) locations as shown in Attachment 4. Seventeen (17) of the indications were initially reported with the bobbin coil examination and eight (8) with the MRPC examination. Loose parts were observed in an additional three (3) locations during SSI. There were no indications of wear associated with any of the PLP indications or any of the loose parts that were reported. Additional information is included in Table 4.

Although no primary side ECT was performed, SSI reported thirteen (13) loose parts in SG 2. Nine (9) were removed. Three (3) pieces of Flexitallic gasket and one (1) sludge rock remain wedged between tubes. No wear associated with any of the loose parts in SG 2 was reported during the performance of the visual examination.

In summary, 100% of the tubes in SG 1 (8522 tubes) were inspected, TEC-TEH. There were no tubes that required repair as a result of this examination. No tubes were plugged or otherwise repaired on a discretionary basis. As a result of the inspection, SG 1 was classified as C-1. A listing and map of tubes reported with wall-thickness loss is included in Attachment 6. The maximum wall-thickness loss was 9% TW.
