UNIT 1 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION REGARDING THE CYCLE 13 STEAM GENERATOR TUBE INSERVICE INSPECTIONS NRC Question 1 Your report indicated that 100-percent of the dents and dings greater than or equal to 2-volts between the top of the hot leg tubesheet and the top of the cold leg tubesheet were examined with a +Point' probe. Discuss the results of these
+Point' probe inspections, including the number of dents/dings in each SG. In addition, discuss if there were any new dents/dings or any "anomalous" dent signals.
TVA Response All greater than or equal to 2 volt dents were examined during the Sequoyah (SQN) end of cycle 13 (EOC-13) inservice inspection (ISI) using Plus Point probes and no degradation was identified.
The number of dents identified per SG during the SQN EOC-13 ISI is compared to the number identified during the SQN preservice inspection (PSI) below.
Number of Dents Comparison 90 82 80 70 66 60 Dents >= 2v 50 40 30 25 20 13 15 11 12 10 10 0
SG-1 SG-2 SG-3 SG-4 S1C12 PSI S1C13 E1-1
The total number of dents identified during the EOC-13 ISI was 104 as compared to 130 identified during the SQN PSI.
The differences in the reduction in numbers can be attributed to the following:
- 1. The screening criterion for identifying dents is 2 volts.
It is expected that with operation of the unit an oxide layer forms causing measured voltages to decrease slightly. Some of the baseline dents that were called near 2 volts are measured less than 2 volts during the ISI, thus not meeting the screening criterion. This could also be attributed to eddy current uncertainties.
- 2. During the PSI, the rules for the computerized data system (CDS) for identifying dents were discovered to be too conservative inside the tubesheet. On the first two SGs (#3 and #4) when dents were examined with a plus point coil, some of the signals were actually slight geometry variations in the expanded region of the tube.
For the next 2 SGs and for the ISI (#1 and #2), the rules were modified. Thus fewer dents were identified.
Six new DNT indications were identified during the SQN EOC-13 ISI using the greater than or equal to 2 volt screening criterion and are tabulated as follows showing the comparison to the SQN PSI calls:
RSG Row Col Location Cyc13 ISI PSI 1 8 22 VS3+0.72 2.09v 1.94v 1 16 100 DS1+2.30 4.90v (1) 1 16 122 DS1+2.32 4.05v (1) 1 43 7 VS2+1.28 2.00v 1.93v 3 43 43 C02-1.60 2.41v 1.89v 3 43 49 C02-1.60 2.13v 1.98v Note (1):
A look back to PSI shows a geometry anomaly at the bend transition for these two tubes that was interpreted during the ISI (EOC-13) as a dent. The same small signal was recognized during the PSI as an occasional consequence of the tube bending process and not identified as a dent.
This signal is still present and unchanged.
The discussion above shows there were no new indications or anomalous signals identified during the EOC-13 ISI following operation after the baseline PSI.

NRC Question 2 Please indicate if the 11 wear indications in the area of the 2nd and 4th vertical straps were inspected with bobbin and
+Point' probes. If the wear indications were not inspected with a +Point' probe, please discuss how you concluded that the indications were wear. In addition, the staff noted that several of the wear indications were located in the same general vicinity. Please provide any insights on the pattern of the wear indications.
TVA Response The eleven wear indications in the area of the 2nd and 4th vertical straps were inspected with both bobbin and plus point probes. Wear was confirmed with plus point.
Westinghouse analyzed these wear indications by developing WCAP-16407-P to describe the likely cause and examine the probability of future indications. The results are summarized below.
Cause:
The most likely cause of tube wear was identified as local clearance variations. Vertical strip arrays VS2 and VS4 have no lock-bars so tube to support clearance has the potential for small localized deviations from optimal clearance. For example, when the vertical strips of VS2 and VS4 were welded to the middle arch plates, the strips might have had local deviations in spacing from each other or might have deviated from a vertical orientation due to weld distortion. Either case would result in less than optimal tube to support clearances. It is feasible that a few vertical strips could have slightly larger tube clearances. These larger clearances would result in increased tube vibration amplitudes. While the SQN U1 RSGs upper bundle support (UBS) design provides excellent support against flow induced vibration (FIV), the high circulation ratio, which is beneficial in avoiding tube corrosion phenomena, results in increased fluid forces in the UBS region. In some local regions enlarged tube to support clearances in combination with increased fluid forces might have lead to the mild tube wear indications.
Future Wear Prediction:
Comprehensive wear progression trending data for tube wear at vertical strips was available from operating experience of Reference SGs at a CE plant. The geometry of the UBS is E1-3
similar between the Reference plant and Sequoyah in the local region of interest. Trending demonstrates indication stabilization (i.e., rate slows down as tube to support bearing area increases) and suggests volumetrically linear wear progression. Using SQN U1 RSG Tube Wear Curves of WCAP-16407-P it can be projected that a tube which incurred a 17%
wall penetration in the first cycle, would not reach the ASME Section XI (40%) plugging criteria until sometime during the ninth cycle of operation.
NRC Question 3 Your report provided information about flaws in specific tubes and at specific locations within a tube. In order for the U.S. Nuclear Regulatory Commission staff to better understand where your indications are being detected and for future reference, please provide the following information regarding the design of your replacement SGs: a tubesheet map, a tube support plate diagram, the heat transfer surface area, the tubesheet thickness (with and without the clad),
the lattice grid thickness, the tube support plate thickness, and a description of the U-bend support system, including the thickness and the tubing supported by the various supports.
In addition, discuss whether you have a flow distribution baffle to distribute flow at the top of the tubesheet, including the thickness.
TVA Response Steam Generator Design:
There is no flow distribution baffle in the SQN U1 Replacement SG design.
Sequoyah Unit 1 is a Westinghouse PWR with 4 steam generators. These are replacements for the previous Westinghouse Model 51 steam generators. Each steam generator contains 4983 U-bend tubes made of thermally treated Inconel 690. The generators are designated as Model 57AG. This comes from approximately 57,000 square feet of surface area (57) and an Advanced Grid design for the tube supports, hence 57AG. The tubes are 0.750 in diameter with a nominal wall thickness of 0.043. All support structures are 409SS.
Various descriptions and drawings follow.

Sequoyah Unit 1 Tubesheet The tube sheet, as shown above, is a triangular pitch design with tubes designated by row and column. There are 103 rows and 125 columns in each leg of the four steam generators.
The tubes are expanded full length of the tube sheet using a hydraulic expansion process. There are 13 blank spaces in each tubesheet for stay rods. The locations of these blanks are as follows:
Stay rod tube numbers 79-39 79-63 79-87 47-27 47-51 47-75 47-99 15-15 15-33 15-51 15-75 15-93 15-111 Location of Stay Rods The Advanced Tube Support Grid (ATSG) structures are 409 stainless steel which is a ferritic stainless. Tubes will be even numbered row - even numbered column or odd numbered row

Additional tables list all dimensional and design specifics relative to the support structures within the Sequoyah steam generators and give the u-bend support structures through E1-5
which the various tubes pass. In addition, lists of tube dimensions by row with respect tostraight and curved sections are provided. Finally, figures show drawings of the supports and Ventilated Support Bars (VSB). The tubes through and including row 16 were heat treated the entire length.
