Steam Generator Tube Inservice insoection Reoort l

l This special report is being submitted within 12 months following the completion of the fifth Inservice Eddy Current inspection (ECT) of the Millstone Unit No. 3 Steam Generator (S/G) tubes pursuant to Technical Specification 4.4.5.5.b.

The end of cycle 5 steam generator tube inspection began on April 27,1995 and was completed on May 5,1995. The examination was performed by Westinghouse Nuclear Service Division. A total of 8473 tubes or 38 percent of the total tubes in all generators were examined by full length bobbin coil inspection. The examination significantly exceeded that required by Technical Specification 4.4.5.2.

A brief synopsis of the results of the steam generator tube inspection is provided in the enclosed Table 3, " Millstone 31995 ECT Summary." Additional information on the details of the inspection plan and ECT results are provided in attached tables and figures.

The inspections were performed on Steam Generators 'B' and 'D'. The initial inspection plan consisted of 4220 tubes in S/G 'B' and 4220 tubes in S/G 'D'. Table 1 is a summary of the locations where the initial samples were taken. Table 2 shows a summary of all tests performed.

The evaluation of these results placed both S/G 'B' and S/G 'D' into Category C-2, as defined by the Plant Technical Specifications. The C-2 category resulted from the identification of "one or more tubes, but not more than 1% of the total tubes inspected" as defective. The required action was to inspect an additional '2S' sample (i.e.12%) in Steam Generators 'B' and 'D'. However, since an initial 75 percent sample was used which included 100 percent of the Antivibration Bar Wear (AVB) region, rows > 25, and all defects were identified as AVB, no additional sample expansions were required.

Tube Row 52, Column 89 which required plugging in the 'D' Steam Generator was not required to be counted in the inspection classification. A review of the previous ECT data for that tube, which was inspected in 1991 during Refueling Outage 3 (RFO3), confirmed that none of the three defects had progressed more than 10 percent through-wall after two complete cycles of operation.

Therefore, these defects were not included in the determination of the inspection category.

The 1995 Eddy Current Testing identified flaws greater than or equal to the plugging limit in ten tubes (one in S/G 'B' and nine in S/G 'D'). The plugging limit is defined in Technical Specifications 9511210250 951114 PDR ADOCK 05000423 l

Q PDR I

I as an imperfection depth of 40 percent nominal tube wall thickness. All ten tubes exhibited degradation attributed to AVB wear. These tubes in addition to tube location Row 52, Column 89, are identified in Table 4, " Location of Tubes Plugged During RFO5", and were removed from service utilizing Westinghouse Alloy 690 Tapered Mechanical Plugs. Table 5 provides a historical listing of all tubes plugged on Millstone 3.

During RFOS, six Westinghouse inconel 600 mechanical plugs, determined to be susceptible to cracking, were repaired. The repair included the removal (by driliing) and replacement of the mechanical plugs from the 'B' and 'D' hot leg and cold leg plenums. The actual locations are 4

identified in Table 6, " Plug Repairs." All plugs were replaced with inconel 690 mechanical plugs.

Similar repairs are scheduleu for the eight remaining cold leg Alloy 600 plugs in the 'A' and 'C' Steam Generators during RFO6.

In response to the Callaway findings, the scope of the Millstone 3 steam generator tube inspection program was expanded to include a sample of tubes in the region where Callaway had identified tube cracking. Five hundred tubes from S/G 'B' and S/G 'D' were inspected, from 12 inches above the top of the hot leg tubesheet to the tube end, using the Cecco-5 probe. The location of the tubes selected for Cecco-5 probe testing corresponded to both the Millstora 3 high sludge region and the region where all of Callaway's circumferential cracks had been located. Figures 2 and 8 show the inspection maps for S/G 'B' and S/G 'D' respectively. The results of the inspection program confirmed that tube cracking had not occurred at Millstone 3 in the region where Callaway had observed circumferential cracking. Unlike Callaway, all tubes in the Millstone 3 steam generators are thermally treated. The inspection results from the Millstone 3 steam generators are consistent with industry experience which has shown that no cracking of thermally treated Inconel 600 tubing has ever occurred in a domestic steam generator.

Prior to the inspection, 50 tube locations were selected for examination with a Rotating Pancake Coil (RPC) probe. The tubes were selected based on previous inspection results which showed excessive tube geometry variations caused by the hydraulic tubesheet expansion process. Since these geometry changes result in increasing tube stress, they are considered more susceptible than other locations for developing Primary Water Stress Corrosion Cracking (PWSCC). Since the Cecco-5 probe was qualified to detect PWSCC and it was being employed for detection of Callaway cracking, the original sample of 50 tubes scheduled for RPC exams was done with the Cecco-5 probe. A total of 7 RPC exams were performed at locations selected based on possible tube flaws identified by the Cecco probe. Figures 3 and 9 show the RPC inspection maps for S/G

'B' and S/G 'D' respectively.
