The Results of Condition Monitoring, Including the Results of Tube Pulls and In-situ Testing and Assessment of Accident-Induced Leakage from all Tubesheet Indications.

Waterford 3 did not perform any tube pulls and one in-situ test was required during RF16.As part of Waterford 3's adherence to perform In-situ Screening in accordance with EPRI, TR-1 014983, "Steam Generator In-Situ Pressure Test Guidelines", Rev. 3, all indication identified were screened with one test required.

The flaw was taken to 5600 psig pressure with zero leakage. The tube R18 C1 12 is located in SG# 1. The condition was entered into Entergy's corrective action program.CR-WF3-2009-06592 Flaw found in SG #1 R18 C112 near 07H support requires screening and profiling for possible in-situ pressure testing. This flaw is inspected with the Appendix I technique of the SG Program Guidelines.

In-situ testing is contingency for RF16 and can be completed under the SG Inspection and Repairs WO Based on the Waterford 3 RF16 inspection results and in-situ pressure testing, no tubes contained indications which represented a challenge to structural or leakage integrity and all condition monitoring requirements are satisfied.

Structural and leakage integrity was established by analysis and through comparison of past in-situ testing results as well as by comparison of observed flaw parameters against the leaking testing thresholds established by EPRI TR-1014983 Steam Generator In-Situ Pressure Test Guidelines Rev 3.No primary to secondary leakage is predicted for the eddy current indications observed at RF1 6 in the event of a postulated SLB event. The relative severity levels of the observed degradation was judged consistent with or bounded by the levels associated with the RF1 5 inspection, and recent inspections of similar CE SGs.Only two indications were observed within the tubesheet region. Both were circumferential PWSCC, one in each SG. In SG31 the indication was located at approximately 14 inches below the top of tubesheet, had a maximum +Point amplitude of 0.84 volt in 300 kHz, and had an indicated arc length of 31 degrees. In SG32, the indication was located at the expansion transition, had a maximum +Point amplitude of 0.49 volt in 300 kHz; and had an indicated arc length of 32 degrees. Each indication was below the leakage threshold so the predicted accident induced leakage fr6m these tubesheet indications is zero gpm.

Attachment 1 to W3F1-2010-0031 Page 11 of 14 Waterford 3 has a current Plant Specific Leakage limit of 0.375 gallons per minute for an "accident-induced leakage limit" and applies a reduction of 0.1 gallons per minute to this value to provide the basis for the approved tube leakage integrity criteria.

The inspection requirements described in TS 6.5.9.c.1 applies an alternate repair criteria which utilized this reduction.

The predicted leakage is zero, thus the accident-induced leakage limit is met.During the Waterford RF1 6 steam generator tube inspection, no indications exceeding the structural integrity limits for either axial or circumferential degradation (i.e., burst integrity

> 3 times normal operating primary to secondary pressure differential across SG tubes) were detected.

Therefore, no tubes were identified to contain eddy current indications that could potentially challenge the tube integrity recommendations of NEI 97-06 Revision 2, "Steam Generator Program Guidelines".

Similarly, all operational assessment structural and leakage integrity requirements are satisfied at EOC-1 7 for the degradation mechanisms observed at EOC-16: One tube in SG31 was plugged due to data quality reasons associated with copper deposits.

The location is R106 C148 at the 01H eggcrate location.

A 1.21 volt (maximum) copper signal was reported from +Pt.This signal was evaluated and the tube met the condition monitoring., criteria.Foreign Obiect/Loose Parts Wear Examinations for loose parts were performed as planned. .The PLP indications were re-examined and bounding MPRC exams were performed.

No new foreign object associated wear was reported at RF16.Cold Leg Volumetric Indications At RF1 5, in SG31, one tube (R2 C156) was. reported with a volumetric signal just above the top of tubesheet.

This location was also reported as a volumetric signal at RF14. At RF14, FOSAR showed no evidence of a PLP and the +Point eddy current data showed no evidence of a PLP. A PLP was likely adjacent to this tube at one point in time but is no longer present. At RF1 4 the indication was sized at 21 %TW and left in service.The RF15 +Point amplitude is essentially equal to the RF14 value, and is sized at 26%TW. The RF16 +Point eddy current data again shows no evidence of a PLP. This indication was again left in service. There was no change in signal parameters between RF15 and RF16.At RF1 5, in SG32 a volumetric signal (R1 04 C30) was reported the Attachment 1 to W3F1-2010-0031 Page 12 of 14 approximate mid-span elevation between just above the 07H eggcrate.

A review of the bobbin history'data shows no change in the signal since 1994. This signal is most likely attributed to a manufacturing artifact, such as a lap. The depth based on sizing with the +Point coil according to ETSS 21998.1 was 19%TW at RF15; there was no change in the signal response at RF16. This indication was left in service.Secondary Side Inspections The secondary inspection was performed per the requirements of the Entergy procedure NOECP-257 "Steam Generator Secondary Side Inspections", which includes a full steam drum inspection and feedring.Entergy committed to performing "augmented" examinations of the batwings.

These inspections were completed during RF1 6.The inspections were completed concurrently but were documented separately.

The secondary side inspectionswere documented in WO-116193 and WO-1i16208.

The augmented examinations were performed under WO-001 53097 and WO-00153098.

The augmented examination results, were reviewed and evaluated by Engineering.

The evaluated results are attached in the Corrective Action Program.For SG31 the augmented inspection result is documented in CR-WF3-2006-03966 CA-0063.For SG32 the augmented inspection result is documented in CR-WF3-2006-03966 CA-0064.Summary results are stated: CA-0063 Action This corrective action is to document the results of augmented inspections performed during Refuel 16 of the secondary side of the Steam Generator

Through-Tube Bundle Inspection, a Bottom-Up Inspection of the batwings in the central stay cavity region, and a Foreign Object Search and Retrieval (FOSAR). All inspection results met the established acceptance criteria.

There were no changes to the extent of condition or the critical variables that were the basis for the mitigating actions taken in RF14, Cycle 15 Operational Assessment, and RF15. Additionally, the assessments performed in RF14, the October 2007 Mid-Cycle 15 outage (P0-07-01), and RF15 remains valid and bounding.Waterford 3 plans to replace both steam generators during RF1 7 (Spring 2011) outage.The full inspection report is attached to the Corrective Action.

Attachment 1 to W3F1-2010-0031 Page 14 of 14 Inspection per NOECP-257 "Steam Generator Secondary Side Inspections".

During the feed ring inspections of Steam Generator No".1 per NOECP 257 and W/O 116193 it was discovered that weld between the Elbow Tee Assembly and the feed ring distribution box is broken. The elbow tee assembly is completely broken off. The elbow tee assembly is visible and is resting between the outer shell of the steam generator and the shroud around the tubes., Discovery of missing Vent -Tee entered into the Corrective Action Program as CR-WF3-2009-06504.

The cause of the failure was determined to be Flow Accelerated Corrosion (FAC). As an extent of condition effort, SG32 was drained and re-examined.NDE measurements were made of the distribution box and feed rings of both Steam Generators.

The inspection results were entered into the Corrective Action Program under Condition, Reports CR-WF3-2009-06622 and CR-WF3-2009-06629.

The conditions were evaluated by Engineering and Westinghouse.

Operation of the SG with the missing vent tee was evaluated found to be acceptable for a cycle of operation.

The issue remains in the Corrective Action Program as a Significantly Degraded Non-Conforming (SDNC) item. The missing vent tee was located in the down'comer region and retrieved.

There was no contact with SG tubing..A small sized screw (size M2 x3mm) from a communications belt was noted as missing and was assumed to be left in SG32. The condition was entered into the corrective action program as condition report, CR-WF3-2009-06206.

The condition was evaluated by Engineering and Westinghouse as acceptable for a cycle of operation.

FOSAR in each Steam Generator was completed in both the annulus region and the blow down tube lane. These inspections revealed no loose parts.H. Effective Plugging Percentage for all Plugging in Each Generator.
