Attachment 2 Invessel Visual Inspection Report The ASME Section Xl inspections credited during Q1 R23 IVVI activities include the once-per-period B-N-1 inspection of the reactor vessel interior and B-N-2 inspections of reactor vessel interior attachments.
Credit is being taken for the BWRVIP examinations in place of the B-N-1 and B-N-2 examinations in accordance with Quad Cities Station Relief Request 15R-06, "Request for Relief for the Use of BWRVIP Guidelines in Lieu of Specific ASME Code Requirements on Reactor Vessel Internals and Components Inspection In Accordance with 1 OCFR50.55a(a)(3)(i)
Alternative Provides Acceptable Level of Quality and Safety".To implement the requirements of the Boiling Water Reactor Vessel Internals Program (BWRVIP), GE-Hitachi (GEH) was contracted to perform the In-Vessel Visual Inspections (IVVI). The following components and assemblies were examined:* Visual inspections of the four Steam Dryer wall support lugs* Visual inspections of two Jet Pump Attachment welds RB-1* Visual inspections of six Upper Sample Bracket Attachments
* Visual inspections of six Lower Sample Bracket Attachments
* Visual inspections of four Upper Guide Rod Support Bracket Attachments
* Visual inspections of two Lower Guide Rod Support Bracket Attachments
* Visual inspections of Core Shroud Vertical welds V6, V29, V30, V31, and V32* RPV interior surfaces in areas near BWRVIP exams in accordance with Relief Request 15R-06.To implement the requirements of the Boiling Water Reactor Vessel Internals Program (BWRVIP), GE-Hitachi (GEH)was contacted to perform the In-Vessel Visual Inspections (IVVI) and Ultrasonic Testing (UT). The following components and assemblies were examined:* 67 components on jet pump assemblies in accordance with the BWRVIP-41 Rev. 3, "BWR Jet Pump Assembly Inspection and Flaw Evaluation Guidelines".
* 38 core spray piping welds via visual exam in accordance with the BWRVIP-18 Revision i-A, "BWR Core Spray Internals Inspection and Flaw Evaluation Guidelines".
* 16 core spray piping P4 welds via UT exam in accordance with the BWRVIP-18 Revision i-A, "BWR Core Spray Internals Inspection and Flaw Evaluation Guidelines".
0 All 12 core spray sparger brackets, 50% of the sparger nozzle S3a/b welds (on the upper spargers), all 4 core spray sparger T-box cover S1 welds, 2 of 4 core spray lower sparger drain plug $3c welds, all 8 core spray sparger T-box S2 welds and all 8 of the sparger pipe end cap S4 welds in accordance with the BWRVIP-1 8 Revision 1-A, "BWR Core Spray Internals Inspection and Flaw Evaluation Guidelines".
Attachment 2 Invessel Visual Inspection Report* 5 core shroud vertical welds in accordance with BWRVIP-76 Revision 1, "BWR Core Shroud Inspection and Flaw Evaluation Guidelines".
e 4 Attachment welds for the steam dryer support lugs in accordance with BWRVIP-48-A, "Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines".
0 4 Attachment welds for the steam dryer guide rod support bracket in accordance with BWRVIP-48-A, "Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines".
e 2 Attachment welds for the steam separator guide rod support bracket in accordance with BWRVIP-48-A,"Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines".
* 12 Attachment welds for the surveillance sample holder brackets in accordance with BWRVIP-48-A, "Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines".
e Top guide rim weld at 20 cell locations in accordance with BWRVIP-26-A, "BWR Top Guide Inspection and Flaw Evaluation Guidelines".
0 4 top guide aligner assemblies in accordance with BWRVIP-48-A, "Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines".
* Steam dryer examinations of the tee to cap doubler welds. Dryer inspections were performed in accordance with BWRVIP-139-A, "Steam Dryer Inspection and Flaw Evaluation Guidelines".
In addition to the BWRVIP inspection guidance, the following augmented examinations were also performed as part of the Q1 R23 IVVI activities:
* 21 jet pump components not required by BWRVIP-41 Rev. 3, "BWR Jet Pump Assembly Inspection and Flaw Evaluation Guidelines" per programmatic requirements.
* 2 Nuclear Instrument Dry Tubes in accordance with GEH SIL 409-Rev 4* Welds and flow-holes on 4 feedwater spargers per NUREG 0619* Selected cast austenitic stainless steel components in accordance with license renewal commitments.
* Re-inspection of mechanical damage at 1 steam separator location per programmatic requirements.
Multiple indications (gouges and rub marks) were identified on all four of the Steam Dryer wall support lugs. These indications were previously observed in Q1 R22. A comparison of the inspection results from Q1 R22 to Q1 R23 found no significant change to the previous indications and no new indications were identified.
These indications are documented in IR 2464537 and evaluated for continued service under EC 400050. Quad Cities will continue to monitor these conditions in accordance with the Reactor Internals Program.}}
