Banks 3 and 4 was deformedWeld was repaired for TB-4/5-02 andseven (7) broken/damaged tie barsreplaced with EPU-qualifiedreplacements.

Scope was expanded to visually inspect(VT-I) all "red" weld locations (locationsimportant to dryer integrity) inaccordance with BWRVIP-139. Inaddition, high stress weld locations asidentified in the steam dryer analysis forEPU were VT-i inspected as well aslocations subject to load increase oncethe center tie bars failed (due to vanebank displacement). During the courseof these additional scope exams, threevertical welds (2V01, 2V10, and 5V10)on the ends of the 3/8-inch plate attachedto the vane bank dryer units were found

19

to have no weld metal present forapproximately six inches at the top of thewelds. These three welds were repairedand restored to their original designcondition.

All repairs will be inspected during theU2C16 RFO in 2011 to ensure thatstructural integrity of the dryer ismaintained. Additionally, any originaltie bars that have not yet been replacedwill be replaced during the U2C16 RFOin preparation for initiation of EPUoperation during the U2C17 Fuel Cycle.Dryer Drain Channel Welds associatedwith Drain Channels 1-4 and DryerManway Cover were VT-I inspected inaccordance with BWRVIP-139.

Baseline UT performed on welds HIthrough H7 per BWRVIP guidelines.Indications identified in 4circumferential welds. No examinationson vertical welds. No repair required.

UT examinations were performed onwelds H-I through H-4 including aportion of vertical weld V16.Examination of welds H5-H7 wasdeferred to fall 2006. Single sided UTexaminations were performed on weldsH-I through H-3 with welds H-4 andvertical weld (V-16) receiving dual sidedexaminations. Percentage of weldsexamined: HI (54.9%), H2 (55.7%), H3(63.9%), H4 (58.4%). The previouslyidentified eight (8) flaws in HI showed anet decrease in length. No new flaws inH2 were identified. The eight (8) flawsin H3 were reexamined with one (1) newflaw identified for a total increasedchange in flaw length relative to totalweld length of 7.5 %. Two (2) newminor flaws were discovered in the HAZof H4. In addition, a total of eleven (11)minor indications were identified in thebase metal adjacent to H4. Six (6) of theindications exhibited characteristicsassociated with Stress CorrosionCracking (SCC) in areas subjected tocold working during the shroudfabrication/installation process. Theremaining five (5) indications did notexhibit characteristics of SCC butappeared to exhibit characteristicscommonly observed from localized

Fall 2006 UT UT examinations were performed on(RE23) welds H5, H6a, H6b, and H7 using

phased array. Two (2) sidedexaminations were performed on allwelds except H7 that received a one-sided UT examination. Coverage wasestimated at greater than 72% for weldsH5, H6a, and 1H6b. H7 received greaterthan 53% coverage. A previouslyidentified indication in H5 was re-examined with no apparent change. Apreviously identified indication in H6awas re-examined with no apparentchange. A new minor indication wasdiscovered in weld H6b in an areapreviously scanned in RE16 (1995).

Core Shroud 1999 (2R05) UT A UT baseline of H3, H4, H5 and H7 wasperformed. H4 was the only shroud weldexamined from two-sides. Indicationsidentified on 1.D. of H3, H5, and on O.D.of H3, H4, and H5. No indicationsidentified at H7. Scope expanded toinclude UT of all remainingcircumferential welds (HI, H2, and H6).Indications identified on I.D. of HI, H2,and H6 and on O.D. of HI. Shroud wasreclassified as a Category C, un-repairedshroud.

Full structural margin was calculatedusing one cycle of crack growth.Structural analysis was re-performed in2R06 and again in 2R07. Re-examination was scheduled for H 1, H2,H3, H4, and H6 in 2R08 per site-specificevaluations. H5 and H7 are scheduled forre-examination in 2R10.

UT was performed on H I and H6 fromone-side with approximately 60%coverage. A two-sided UT wasperformed on H2, H3, and H4 withapproximately 60-63% coverage.Approx 21.5% of the ring-side scanswere obtained for H2 and H[3 with a newphased array technique.

Due to equipment problems, verticalwelds could not be screened by UT perBWRVIP-76. As a result, all verticalwelds were assumed to "screen in", andan EVT-1 was performed on these weldsfrom the shroud OD. Reinspection of thevertical welds, either UT or two-sidedEVT-1. is scheduled for 2007(2R09).

Another analysis of the indications foundin 2R08 (2005) on horizontal welds HI,H2, H3, H4, and H6 was performed todemonstrate that structural margins aremaintained until 2009 (2RI 0). Theanalysis demonstrated acceptable safetyfactors are maintained and a reinspectionby UT is scheduled for 2R10.

UT was performed on H3, H4, H5 and H7from two-sides. A one-sided UT wasperformed on H2 ring-side concurrentwith H3 ring-side exam. Coverage andresults are as follows:

H7 weld had no flaws identified andcoverage was greater than 50%, thereinspection interval was determined tobe 10 years per BWRVIP-76 Table 2-1.

Due to multiple tooling issues andfailures, portions of the H5 and H7 weldswere also visually examined via EVT-Imethod from the OD surface only.Visual coverage on the H5 welds is19.5% of the weld length with norecordable indications identified. Visualcoverage on the H7 welds is 13.2% of theweld length with no recordableindications identified.

UT was performed on all 8 vertical welds(V7, V8, VI5, V16, V17, V18, V25, andV26). One indication was identified onthe ID of V17 and was 1.4 inches inlength. Coverage ranged from 77% to96% due to various configurationinterferences.

In addition, a structural re-analysis wasperformed for several horizontal welds.Additional cycles were justified and thenext re-examination is as follows:HI -2R13, H2-2R13, H3 -2R15, H4-2R15, H5 - 2R15, H6 - 2R13, H7 -
