Attachment to 1CAN041404 Page 1 of 19 Responses to RAIs Regarding 1R24 Steam Generator Tube Inspection Report By letter dated October 23, 2013 (ML13296A746), Entergy Operations, Inc. (Entergy),
submitted the Arkansas Nuclear One, Unit 1 (ANO-1) Steam Generator Tube Inspection Report for refueling outage 1R24 to ensure compliance with ANO-1 Technical Specification (TS) 5.5.9, "Steam Generator (SG) Program." The U.S. Nuclear Regulatory Commission (NRC) staff is currently reviewing the submittal and has determined that the additional information listed below is needed to complete its review:
: 1. Section 3.7 indicates that there is tie rod bowing in the plastic range in the first-span tie rod region of both steam generators (SGs) and that as a result there will be some residual bowing during normal power operation. Please discuss what effects this residual bowing may have on normal operation of the SGs.
Based on the amount of plastic deformation that currently exist and projected to exist, tubes were plugged and stabilized to surround the affected tie rods. The gap between the tie rods and the adjacent tubes is ~ 0.25 inches. Therefore once the amount of plastic deformation exceeds that distance, there is a potential for the tie rod to come in contact with a tube and could potential result in mechanical wear. Therefore the affected tubes were removed from service by plugging and stabilizing.
: 2. Section 3.7 indicates that the direction of tie rod bowing in the first span for SGs A and B are not consistent. For SG B, some of the bowing is circumferential as opposed to being all radially inward, as with SG A. Please discuss any insights on why there is a difference in the direction of bowing.
The direction of the bowing is a direct result of where the tube support plates (TSPs) come in contact with the inner shroud as well as which plates and how many are affected by the inner shroud. As the component cools off, the frictional forces of the TSPs that come in contact with the inner shroud increase and cause a downward force on the tie rods. Based on where those contacts are cause the rods to bow in different directions. This has generally been consistent but can change slightly from outage to outage.
: 3. As discussed in the telephone call on July 9, 2013 (ADAMS Accession No. ML13172A029), peripheral tubes were inspected for signs of denting to assist in identifying locations where the tube support plates are suspected not to be freefloating. Please discuss the results of these inspections and your assessment of these results.
The top tube support plate (15S) showed a slight circumferential progression in the periphery along the W and or X axis as shown in the plot (red indications are the new dents (DNTs) in 1R24). The progression was not as significant as seen in prior outages.
All voltages were below or near 1.0 Volts, and there was no noticeable difference in any repeat DNT voltage.

Attachment to 1CAN041404 Page 2 of 19 The circumferential extent of locking at the top TSP appears to be increasing with each operating cycle. The small dent analysis of the tubes in the drilled-only holes of the top TSP are used to monitor this general progression of the overall mechanism associated with tie rod bowing. An increase in circumferential extent of locking may indicate that incremental load is being applied to the tie rods (with potential consequent increase in number of rods with bowing and/or increased magnitude of bowing). Of course, the as-inspected changes in tie rod bowing are the final measure of the progression of the postulated mechanism.
: 4. Figure 3.7.1 indicates that one tie rod in the first span may have been in contact with a tube during normal (hot) operating conditions. Please confirm that no tube wear was identified in the first span region of the tube that was in contact with the tie rod.
The NRC staff notes that in 1 R24 (2013 outage), tube stabilization and plugging was performed in tubes that were predicted to be in contact with the tie rods during operation (hot conditions). Please explain if this is a change in practice since the prior inspection.
In the 180 day report on Figures 3.7.1 and 3.7.2, the red dots on the graphs indicate when that location was plugged and stabilized. Preventative plugging was started in the first in-service inspection in 1R20 for SGA and 1R23 for SGB. This practice has been performed

Attachment to 1CAN041404 Page 3 of 19 and was continued in the last outage (1R24) to plug out to the point that would allow for four additional thermal cycles to prevent contact. To date there has been no tube wear associated with tie rod bowing in either generator.
: 5. Figure 3.7.1 indicates that the bow in 1 R23 had slightly less bow than was observed in 1R22. Please discuss any insights on condition.
When the component is returned to service (normal operating temperature and pressure),
the TSPs are released from the inner shroud as it expands due to thermal expansion.
During the next cool down, the TSPs may adhere to the shroud at different locations and times which results in more or less bowing.
: 6. Please provide a listing of the location, orientation, and measured size of all service-induced wear indications detected during the 1 R24 (2013) outage and discuss any wear indications attributed to interaction between the tube and tube support plates.
This was not a code inspection so the list of TSP wear was only on those tubes near the tie rods that were part of the planned scope or that were contained in the previous tube to tube wear tubes. Therefore it was not included. Tables 1 and 2 lists the tubes for SGA and SGB, respectively, that were identified based on the limited scope inspection.
: 7. The 95th percentile growth rate in SG A appears higher in 2013 (1 R24) than it was in 2011 (1 R23). In addition, the maximum growth rate observed was higher in SG B in 2013 than it was in 2011. Please discuss any insights on this condition since the growth rate for wear tends to decrease with time. In addition, please discuss how this condition was factored into your operational assessment (an increasing growth rate with time).
The 1R23 operational assessment was performed using a fully probabilistic model. Since this was a limited scope inspection, not all tubes were equally represented across the bundle. Once through designs, tend to have higher wear in the periphery than in the inner bundle. The maximum value (12.88%) was a periphery tube which was removed conservatively due to the higher growth rate. The value still fell within the distribution of the values used in the probabilistic model. Since the 1R23 data was based on a 100%
inspection, one would expect it to be lower since it has all of the inner tubes in the population while this inspection focused on those around the tie rods and the periphery from the 9th TSP to the upper tube end.
: 8. In Tables 3.7.5 and 3.7.6, depths are not provided in the X-probe column when two wear scars were detected by an array coil. Please clarify why the depth for each of the wear scars was not provided and discuss how the indications could have been sized with the array (X-) probe).
The reported depth was the total depth for the multiple wear scars based on the bobbin correlation. The indications do not reflect the locations with multiple wear scars at the same elevation since the depth sizing was based on the bobbin correlation. For the evaluations

Attachment to 1CAN041404 Page 4 of 19 for depth and growth, the multiple indications are conservatively treated as one indication with the total depth for both wear scars. X-probe data was taken on all tube-to-tube wear.
This was not included in the original submittal. The following tables list those tubes with multiple indications and the depths by X-probe:
