TURKEY POINT UNIT 3 L-2011-119 Steam Generator Tube Inspection Report Page 1 of 11

Background

This report is provided in accordance with Turkey Point Unit 3 Technical Specification 6.9.1.8, "Steam Generator Tube Inspection Report" for the inspection conducted October 7th to 12th, 2010 during refueling outage twenty-five (TP3-25). TP3-25 is the third refueling outage in the third (3 rd)

ISI period (60 EFPM). The replacement Westinghouse model 44F steam generators (SGs) were installed in PTN Unit 3 in April, 1982. The TP3-25 inspection was the second inspection in the 3rd ISI period and also the last scheduled inspection in the 3rd ISI period. The SGs have accumulated 22.19 effective full power years of operation at the TP3-25 refueling outage.

Following the TP3-25 refueling outage, Turkey Point Unit 3 initially entered HOT SHUTDOWN on November 2, 2010.

The TP3-25 SG tube inspections were conducted in all three SGs (3A, 3B, & 3C) as described below.

a. The scope of inspection performed on each steam generator The scope of this examination is summarized in Table 1 below and is established to meet the following requirements:
a. Technical Specification 6.8.4.j "Steam Generator (SG) Program"
b. Technical Specification 6.8.4.j.d.2 "Inspect 100% of the tubes at sequential periods of 120, 90, and, thereafter, 60 effective full power months. The first sequential period shall be considered to begin after the first inservice inspection of the SGs. In addition, inspect 50% of the tubes by the refueling outage nearest the midpoint of the period and the remaining 50% by the refueling outages nearest the end of the period. No SG shall operate for more than 48 effective full power months or two refueling outages (whichever is less) without being inspected."
c. Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines: Revision 7. EPRI, Palo Alto, CA: 2007. 1013706.

The TP3-25 inspections are intended to satisfy the surveillance requirement for the 2nd half of the 3rd ISI Period.

The basis for bobbin and +PointTM tube examinations is given in Table 1.

Row 33 column 44 in SG 3A was un-plugged and tested with bobbin and +PointTM to address previous AVB wear. This tube was stabilized and re-plugged, but is not counted in Table 3 above.

(2)

Two tubes (R6-C45 and R7-C45) were plugged based on the presence of wear coincident with a small foreign object located at the top of the second cold leg support (020). A qualified sizing technique is not available to size the tubes for service when a foreign object is still present. The indications in these tubes were sized at 8% and 14%, respectively, for integrity assessment purposes.

(3)

Two tubes (R21 -C61 & R29-C77) were plugged based on wear adjacent to the lower edge of the 04H and 03H supports, respectively. Tube R30-C45 was PTP based on measured AVB wear at AV3.

h.

The effective plugging percentage for all plugging in each steam generator No tube repair methods (i.e. sleeving) are approved for Turkey Point Unit 3 that would have an effect on the effective plugging percentages. Therefore, the effective plugging percentage is equal to the % Plugged in item f. above.

The primary to secondary leakage rate in each SG (if it is not practical to assign the leakage to an individual SG, the entire primary to secondary leakage should be conservatively assumed to be from one SG) during the cycle preceding the inspection which is subject to the report.

No primary to secondary leakage was reported during the preceding cycle of operation.

j.

The calculated accident induced leakage rate from the portion of the tubes below 17.28 inches from the top of the tubesheet for the most limiting accident in the most limiting SG. In addition, if the calculated accident induced leakage rate from the most limiting SG is less than 1.82 times the maximum operational primary to secondary leakage rate, the report should describe how it was determined The accident induced leakage rate from the portion of the tubes below 17.28 inches from the top of the tubesheet is calculated as a ratio of observed normal operating leakage that cannot be attributed to a source other than the tubesheet expansion region. For the operating period preceding the TP3-25 inspection, no operational primary-to-secondary leakage has been observed.

Further, there are no degradation mechanisms that have the potential for leakage.

For Turkey Point Unit 3, the maximum operational primary to secondary leakage rate from the portion of the tubes below 17.28 inches from the top of the tubesheet is multiplied by a factor of 1.82 to determine the accident induced leakage. Since no operational primary-to-secondary leakage has been observed, the calculated accident induced leakage rate from the portion of the tubes below 17.28 inches from the top of the tubesheet is zero.

Therefore, neither the normal operating leakage limit nor the accident induced leakage limits will be challenged during the next operating period.

k.

The results of monitoring for tube axial displacement (slippage). If slippage is discovered, the implications of the discovery and corrective action shall be provided.

Monitoring for tube slippage was completed in accordance with commitment #1 in Ref. 1. No tube slippage was discovered based on the results of the TP3-25 SG inspections.

Secondary Side Inspection Secondary side inspection information is not required by TS Section 6.9.1.8. However, this information is being provided based on NRC requests for additional information regarding previous reports submitted by FPL in accordance with this specification:

Secondary Side Inspections (SSI) during the TP3-25 refueling outage include the following:

Upper Bundle Flush (UBF)

Sludge Lance FOSAR (Foreign Object Search and Retrieval)

Upper Bundle and Top Down Inspection in one SG Upper bundle flush and sludge lancing was completed in all three steam generators. The processes recovered 49 lbs of sludge from SG 3A, 70.5 lbs from SG 3B and 66.0 lbs from SG 3C.

Pre -bundle flush upper bundle and top down inspections were completed in only SG 3B. Deposits observed were very light and therefore, post-flush inspections were not warranted. No abnormalities were noted.

SG 3A During post-lance inspections of SG 3A, one legacy foreign object was removed from the hot leg at location R14-15 C68-69. (Item 1 in Table 5). No tube damage was identified by visual or ECT methods.

One ECT PLP was investigated at R3 C57. (Item 2 in Table 5). The object was fused to the tubesheet within a hard deposit and could not be removed.

SG 3B During post-lance inspections of SG 3B, two foreign objects were successfully removed. One item was located in the H/L at R43 C46-47 (Item 11 in Table 5). The second item was in the H/L annulus, but had no tube contact (Item 12 in Table 5). No tube damage was reported by visual or ECT methods.

Several legacy foreign objects were re-investigated for presence, signs of movement, and the possibility of removal.

(Items 3,5,6,8,9 in Table 5). These items remain fixed in their locations and were not removed. No tube damage was reported at these locations by visual or ECT methods.

TURKEY POINT UNIT 3 L-2011-119 Steam Generator Tube Inspection Report Page 9 of 11 SG 3B (Cont.) Possible Loose Part (PLP) Signals Reported by ECT Possible Loose Part (PLP) Signals reported during the ECT Exam are investigated during FOSAR operations.

During TP3-25, five such PLP indication locations were investigated, and no foreign objects were found at those locations. In SG B, PLP indications were reported during the ECT examination, at the 02C location in tubes R6-C45 and R7-C45. These locations were not accessible due to the location in the tube bundle. Tubes R6-C45 and R7-C45 were plugged based on the presence of wear coincident with the PLP indications. The indications in those tubes were sized at 8% and 14%, respectively, for integrity assessment purposes.

SG 3C Post sludge lancing inspections in SG 3C identified the three new metallic foreign objects in the H/L tube bundle and annulus (Items 14,16,17 in Table 5). All three objects were removed and no tube damage was observed by ECT or visual.

One legacy foreign object (Item 13 in Table 5) and one new object (Item 15 in Table 5) were seen and are firmly wedged or fused in place. Retrieval attempts were not successful. No tube damage was reported by ECT or visual.

Foreign Object Tracking for SGs A, B, C Items 2, 3, 5, 6, 8, 9, 13, 15 in Table 5 were unable to be retrieved from the SGs. These items will continue to be actively tracked during future FOSAR inspections.

Items 1, 11,12,14,16,17 in Table 5 were removed from the SGs during the TP3-25 FOSAR inspections and will not be actively tracked in the future.

Items 4 and 7 were not observed in either the TP3-23 or TP3-25 FOSAR inspections. These items have been documented, but will not be actively tracked in future outages.

Item 10 in Table 5 was not observed during the TP3-25 FOSAR inspection. Item 10 will continue to be actively tracked during the next FOSAR inspection.

No tube degradation was associated with any of the objects in Table 5. All objects remaining in the SGs have been evaluated for potential impact on plant operation and tube integrity and were determined to be acceptable for the planned operating period.
