Reactor Internals Inspection Histoiy Plant: Browns Ferry Nuclear Plant: Unit 3 Components in Date or Inspection Summarize the Following Information:

BWRVIP Scope Frequency of Method Inspection Result, Repairs, Inspection Used Replacements, Reinspections Core Shroud 1994 UT Baseline (1994) per GE SIL No. 572 for 1997 circumferential seam welds - indications 1998 found in several welds (H-1, H-4, H-5).

2004 Reinspection (1997) per GE SIL No. 572

- indications found in H-7 weld along with previous indications. Full structural margins on flawed welds for at least one additional operating cycle. Vertical welds not inspected.

Reinspection (1998): UT examination of H-l, H-2, H-3, H-4, H-5 performed. A total of 63 indications were recorded. A structural evaluation of H-3 was performed to support continued operation.

Reinspection (2004) per BWRVIP-76:

UT examination of H-5 performed (51.1

% coverage, 37 indications). Current plant-specific calculation allows continued operation through end of Unit 3 Cycle 12 Fuel Cycle (2006); new plant-specific calculation to be performed to support continued operation beyond that time. UT examination of H-6 (3.4 %

coverage, no indications) and H-7 performed (2.2 % coverage, 1 indication); reinspection required in 2006 due to lack of coverage.

Baseline (2004) UT inspection per BWRVIP-76 for Vertical Welds V-5 (61.6% coverage, no indications) and V-6 (61.6% coverage, no indications).

3

2006 UT Reinspection (2006) per BWRVIP-76:

H-6 and H-7 were at the end of their inspection interval. UT examination of H-6 (24.41% coverage (one-sided), 0.0%

flawed per examined weld length) and H-7 (19.44% coverage (one-sided), 3.27%

flawed per examined weld length) was less than the BWRVIP-76 mandated 50%

minimum due to mechanical and physical accessibility problems (e.g., RPV surveillance capsules, sensing lines, etc.)

with the UT inspection equipment.

Plant-specific evaluations demonstrated adequate structural margin exists for continued operation for one fuel cycle.

Both Welds H-6 and H-7 will require reinspection using a two-sided UT technique during the U3C 13 Refueling Outage in 2008.

Attempts were made to examine Horizontal Welds H 1 through H5 and Vertical Welds V6 and V7 one cycle before their inspection interval will expire. UT examinations (one-sided) of H-1 (75.62 % coverage, 5.65% flawed per examined weld length), H-2 (86.1%

coverage, 1.28% flawed per examined weld length), and H-4 (15.92%

examined, 3.24% flawed per examined weld length) were performed.

Inspections of H-3, H-5, V-6, and V-7 were not performed. Plans are to reinspect Welds HI through H5 using a two-sided UT technique during the U3C13 Refueling Outage in 2008.

Welds V6 and V7 will be inspected using a one-sided UT technique during the U3C 13 Refueling Outage in 2008.

2008 UT Reinspection (2008): UT examination of H1 (single-sided) and H2, H3, H4, H5, H6, H7, V5, and V6 (two-sided) performed per BWRVIP-76. The length of the weld inspected was at least 50 percent of the weld circumference in all 4

cases. Flaws observed in five (H1, H2, H3, H4, & H7) horizontal welds and one vertical weld (V5) were less than 20 percent of examined length. Flaws observed in the H5 horizontal weld were less than 30 percent of examined length.

BaiTing license renewal impacts, all horizontal welds with the exception of H5 will not be reinspected until 2018.

The H5 weld (and associated vertical welds) will require reinspection in 2014.

DM Welds Spring UT Performed manual UT of N9 nozzle cap weld 2008/1R23 and the "N8A" jet pump instrument nozzle-to-safe end weld. Both examinations met Appendix VIII criteria. The N8A nozzle-to-safe end weld examination detected no indications.

Manual UT plots in the N9 cap weld indicated a potential flaw that appeared to extend upward from the root area along the interface of the replacement weld and the original nickel alloy butter fusion line. Phased array UT (Appendix VIII qualified) was then used to fully interrogate the weld and characterize the indication. The indication was evaluated to be a circumferentially oriented defect that was 2.3 inches long on the inside diameter and 60%

through wall in a pipe thickness of 0.74 inches.

A SWOL was successfully applied.

Scope was expanded to the "N8B" jet pump instrument nozzle-to-safe end weld with no indications detected.

Spring UT Performed automated phased array UT of 2010/1 R24 Recirc nozzle N2D, N2F, N2G, N2H, and N2K nozzle-to-safe end welds, which are all Category C welds according to BWRVIP-75-A criteria. All examinations met Appendix VIII criteria. The N2D and N2H examinations required some weld conditioning prior to UT.

The examinations resulted in no reportable indications.

VT-I VT-I examined all twenty main wedges (WD-1). Minor wedge wear was identified on JP 18, JP 19, and JP 20.

WD-2a, WD-2b, MX-7, welds were also examined on JP 18, JP 19, and JP 20 as part of the expanded scope required from identifying main wedge wear. Minor wedge rod wear was identified on JP 4, JP 18, JP 19, and JP 20. Since slip joint clamps (installed in 2006) mitigate slip joint bypass leakage vibrations, this main wedge damage and rod wear was determined to be caused by turbulent flow. Two auxiliary wedges were installed around both the shroud and vessel side set screws on JP 19 and JP

20. JP 18 has one previously installed auxiliary wedge around the shroud side set screw. The main wedge wear and rod wear were found to be acceptable for continued service without repair.

Set screw gaps (AS-1) and tack welds (AS-2) were inspected at all locations not blocked by an auxiliary wedge. Gaps were identified on vessel side setscrews of JP 2 (20 mils), JP 3 (5 mils), JP 9 (14 mils), and JP 20 (8 mils). One auxiliary wedge was installed to repair the gap on the vessel side set screw of JP 2. The remaining gaps were evaluated as acceptable without repair. Previously identified gaps at JP 4, JP 7, and JP 19 are no longer visible. Cracked tack welds were re-inspected on the shroud side setscrews of JP 8, JP 12, JP 14, JP 17, and JP 19 with no change in condition noted.

All 20 Slip Joint Clamps were examined after one cycle of operation. No 97

indications were identified.

One previously identified indication on JP 13-14 RS-9 weld was unchanged. No other indications identified.

VT-I VT-I examined all twenty main wedges (WD-1). Previous wedge wear identified on JP 18, JP 19, and JP20 had no change in condition reported. Minor wedge rod wear was identified on JP08, and previously identified rod wear on JP04, JP 18, JP 19, and JP20 had no change in condition reported. No indications were identified on the wedge rod tack welds of JP04, JP08, JP18, JP19, and JP20.

Set screw gaps (AS-I) and tack welds (AS-2) were inspected at all locations with previously identified indications.

Gaps were identified on vessel side setscrews of JP03 (4 mils) and JP09 (13 mils). These gaps were acceptable without repair. Cracked tack welds were re-inspected on the shroud side setscrews of JP08, JP12, JP14, JP17, and JP19 with no change in condition noted, except that the second tack weld of JP 17 now has a small indication identified. All were evaluated as acceptable.

All 20 Slip Joint Clamps were inspected.

The mid-support of two clamps (JP 11 98

and JP 19) was identified as having minor wear into the top ledge of the diffuser.

One clamp (JP17) was identified as having slight movement from its original installed position. Indications were evaluated as acceptable with no repairs or re-work performed. No other indications were identified.

Five auxiliary wedges were inspected after one cycle of operation: JP02 VS, JP19 SS, JP19 VS, JP20 SS, and JP20 VS. No indications were identified.

were examined to the requirements of ASME Section XI, Appendix VIII, Supplement 10, using automated ultrasonic equipment. These eight (8) welds all contained Alloy 82/182 weld material. No failures were identified.

Included in these eight examinations was the examination of vessel nozzle to safe end weld N2D NOZ-SE, which was added to the UI-15RIO inspection scope when review of its previous 2004 exam data (prompted by EPRI/BWRVIP Letter 2007-367 as the result of recent industry DM weld issues) identified a 'sub-surface reflector or discontinuity'. The U1-15R10 examination determined that the sub-surface flaw was from original weld manufacture and that it has not grown, nor are there any forces causing it to grow.

The sub-surface flaw meets ASME Section XI Table IWB 3514-2 requirements.
