Steam Generator Tube Inspection Report Arkansas Nuclear One - Unit 1 Docket No. 50-313 License No. DPR-51

Dear Sir or Madam:

Arkansas Nuclear One, Unit 1 (ANO-1) Technical Specification 5.6.7 requires that a Steam Generator (SG) tube inspection report shall be submitted within 180 days after initial entry into mode 4 following completion of an inspection.

Attached is the SG Tubing In-service Inspection Report which presents the results from ANO-1I's scheduled refueling outage (1 R20) inspection. The inspection was completed in May 2007.

This submittal contains no commitments. Should you have any questions regarding this report, please contact Fred Van Buskirk of my staff at (479) 858-3155.

Sincerely, DEJ/f(

Attachment I ICAN110701 Arkansas Nuclear One, Unit Steam Generator Tube Inspection 1 Report to 1CAN 110701 Page 1 of 5 ARKANSAS NUCLEAR ONE, UNIT I STEAM GENERATOR TUBING 180 DAY INSPECTION REPORT I INTRODUCTION Arkansas Nuclear One, Unit 1 (ANO-1) Technical Specification (TS) 5.6.7 requires Entergy Operations to submit a 180 day report to the NRC that outlines the details of the steam generator (SG)'tubing inspections that were performed during the reporting period. The report shall include:

1. The scope of inspections performed on each steam generator.
2. Active degradation mechanisms found.
3. Nondestructive examination techniques utilized for each degradation mechanism.
4. Location, orientation (if linear), and measured sizes (if available) of service induced indications.
5. Number of tubes plugged during the inspection outage for each active degradation mechanism.
6. Total number and percentage of tubes plugged to date.
7. The results of condition monitoring, including the results of tube pulls and in-situ testing.

The operating period for this report includes one outage, a refueling inspection (1 R20) in April/May 2007 which was the first ISI following the steam generator replacement outage. This report details the results of that inspection.

2 DESIGN The replacement steam generators for ANO-1 are Enhanced Once-Through Steam Generators (EOTSG) manufactured by AREVA. The EOTSG is a straight shell and tube type heat exchanger installed in a vertical position with bottom supports and such emergency supports as required to accommodate normal and accident loads. The tubing consists of Inconel 690 thermally treated tubing that is 5/8" in diameter with a 0.037" wall thickness. The tubes are expanded full depth hydraulically in the tubesheet.

There are 15 tube supports that are constructed of (SA 240 type 410) stainless steel and are a broached trefoil-hole design.

3 Report Requirements 3.1 The scope of inspections performed on each steam generator.

Table 3.1 lists the inspection scope of 1R20.

This was the first ISI following replacement of the steam generators. The only mechanisms identified were mechanical wear at tube support plates, volumetric and fabrication induced indications. These are listed in Table 3.2.1 for SGA and 3.2.2 for SGB TABLE 3.2.1 SGA INDICATION LIST FOR 1R20 Item No. Mechanism Number of Indications 1 Wear at TSP 690 2 Volumetric 4 3 Dents 3 4 MBM 1 5 Bulge 1 6 Proximity 33 7 Potential Loose Parts 0 to 1CAN 110701 Page 3 of 5 TABLE 3.2.2 SGB INDICATION LIST FOR 1R20 Item No. Mechanism Number of Indications 1 Wear at TSP 512 2 Volumetric 18 3 Dents 3 4 MBM 2 5 Bulge 0 6 Proximity 0 7 Potential Loose Parts 5 3.3 Nondestructive examination techniques utilized for each degradation mechanism.

The only service induced mechanism is wear at the tube support plates. Due to the large number of indications, these are listed in the back of the report in attachment 2 for SGA and attachment 3 for SGB.

3.5 Number of tubes plugged during the inspection outage for each active degradation mechanism.

There was one tube plugged during the outage in SGB for preventative reasons. This was due to a 28% TW wear indication. The tube was also stabilized full length. This is listed in Table 3.5.1 below. There were 2 tubes preventatively plugged during fabrication in SGA due to failed expander tooling. This is listed in Table 3.6.1 Table 3.5.1 Tubes Plugged Row Tube Indication Location Plug Type Stabilizer 10 63 PCT 10S + 0.52 Mechanical Full Length Rolled Plug 3.6 Total number and percentage of tubes plugged to date.

There are no sleeves installed in either generator. The plugging information is listed in Table 3.6.1.

All condition monitoring requirements were met. There were no indications that exceeded performance criteria or in-situ screening limits. There were no tube pulls required.

An item of note was the fact that proximity indications were identified in SGA.

Proximity is an indicator of tube bowing. The bowing resulted from stay rod bowing due to a compressive load applied during cool down from locking of the tube support plates in the upper shroud. Information related to the stay rod bowing was presented to the NRC in a meeting conducted on August 29, 2007. Additional inspections are planned for 1R21 (next refueling) to validate the root cause.

The growth rate of the tube support plate wear was considered moderately low such that it would have supported skipping 2 cycles.
