Dresden Road, Morris, IL60450 Section I Introduction The seventeenth Inservice Inspection (ISI) of Dresden Unit 3 was performed during the D3R17 outage which began on October 8, 2002 and was completed on October 26, 2002. This was the second of two scheduled refuel outages in the third inspection period of the units 3rd 10-year ISI Inspection Interval which commenced on March 1, 1992. The third inspection period commenced on November 1st, 1999 and is currently scheduled to end on October 31, 2003. In addition to examinations performed during D3R17, a number of examinations were performed during on-line operation of Unit 3. This report contains all examinations completed during D3R17 and on line examinations which were not included in the previous Unit 3 Summary Report (dated December 29, 2000).

General Electric was contracted to perform the non-destructive examinations and reactor vessel visual examinations during the refuel outage. Dresden Engineering Programs Group performed the remaining visual and NDE examinations during D3R17 as well as the on line examinations.

The Authorized Nuclear Inservice Inspectors (ANII) services were provided by The Hartford Steam Boiler Inspection Insurance Company of Connecticut. The ANII reviewed procedures, personnel qualifications, instrument and material certifications, and examination results.

All examinations were performed in accordance with the Dresden Station ISI Program, Dresden Station Technical Requirements Manual, the ASME Boiler and Pressure Vessel Code,Section XI, 1989 Edition and 1998 Edition (implemented in accordance with Relief Request MCR-02 for Containment ISI), Generic Letter 88-01, BWRVIP-75, and In-Vessel Visual Examinations in accordance with BWRVIP Inspection and Evaluation Guidlines.

Dresden Road, Morris, IL 60450 Section Ii Scope of Inspection Abstract of ISI and Augmented Examinations IS! and Augmented Examinations Table A contains a list of components examined prior to, during and after the D3RI 7 refuel outage, to satisfy the requirements of the Dresden Station ISI Program, Dresden Station Technical Requirements Manual, the ASME Boiler and Pressure Vessel Code,Section XI, 1989 Edition and 1998 Edition (implemented in accordance with Relief Request MCR-02 for Containment ISI), Generic Letter 88-01 and BWRVIP-75. Those items which were examined and meet the acceptance standards of ASME Section XI or Generic Letter 88-01 are identified as "Acceptable" under the results column. Those items that required further evaluation are identified with "Section III" in the results column and are further discussed in Section III of this report.

Snubber Examinations (Technical Requirements Manual 3.7.H)

All Section XI Class 1, 2 and 3 safety-related snubbers are visually (VT-3) examined in accordance with Dresden Technical Requirements Manual 3.7.H. A sample population of snubbers are functionally tested every outage. Table A includes all the snubbers functionally tested during D3R1 7 and any visual examined snubbers that required further evaluation.

Snubbers that required further evaluation are identified with "Section III" in the results column and are further discussed in Section III of this report.

Summary of Reactor Vessel Weld (Category B-A) Examinations The Unit 3 reactor vessel shell welds are examined as required by IOCFR50.55(a) and ASME Section XI. These welds are addressed under Examination Category B-A, Item numbers B1.1 1, Circumferential Shell Welds; Item B1.12, Longitudinal Shell Welds; and Item B13.30, Head to Flange Weld. Two relief requests were associated with these inspections. First, relief was requested, and subsequently granted, from requirements to examine welds under item B1.11.

The technical basis for this request is established in BWRVIP-05. Second, a schedule exemption was requested, and subsequently approved, to allow performance of these inspections over an additional refueling outage. Otherwise, the entire inspection would have been required during D3R17, the last outage in the third inspection interval. The basis of this request was to allow the station to attempt to take advantage of a new inspection technology, the AIRIS 21 system, to achieve an increased coverage without significantly impacting the outage.

Summary of Vessel Interior Examinations Attachment A contains a summary of examinations performed to satisfy the requirements of ASME Section XI categories B-N-I, B-N-2, and various special examination requirements.

Details of the examinations, results, and corrective measures are included.

Exelon Generation Company (EGC, LLC) October 2002 Inservice Inspection 200 Exelon Way, Kennett Square, PA, 19348 Unit No. 3; National Board No. N-139 Commercial Service Date: 11-16-71 Dresden Nuclear Power Station 6500 N.Dresden Road, Morris, IL60450 Section I1 Scope of Inspection Attachment A Summary of Vessel Interior Examinations Examination Category B-N-1 Item B13.10, "Reactor Vessel Interior Surfaces', were VT-3 examined between the closure flange and the top of the shroud over 3600 of the reactor vessel circumference. This exam is required each period. No indications were identified.

Examination Category B-N-2 Item B.13.20, "Interior Attachments Within the Beltline", Accessible Welds, were VT-I examined as required during this interval. These examinations are required to be performed once each interval. The component attachments within the beltline not examined during D3R16 were examined this outage. Specifically, the secondary Jet Pump Riser wall brace attachments designated as weld RB-3 in BWRVIP-41 were examined for all twenty Jet Pumps. No indications were identified.

Item B13.30, "Interior Attachments Beyond the Beltline", Accessible Welds, were VT-3 examined as required during this interval. Several of these examinations were performed during outages prior to D3R17. Some were repeated this outage to capture the more extensively defined inspection recommendations of BWRVIP-48. The locations examined during this outage included all Core Spray piping attachments, all Feedwater sparger end bracket attachments, and all Steam Dryer support lugs. No indications were identified.

Item B13.40, "Core Support Structures", Accessible Welds, were VT-3 examined as required during this interval.

These examinations are required to be performed once each interval. These welds were examined during D3R14.

Core Spray System Examinations Core Spray piping was examined during D3R17 as recommended in BWRVIP-18. Specifically, the known flaw on the P8a weld on the 80r downcomer was ultrasonically examined to verify visual inspection collected during D3R15 and 16. During D3R15, the "bumper clamp" repair was installed which made the specific weld inaccessible to the ultrasonic equipment routinely utilized every second outage. During this outage, a compact pole deployed UT device was used by FTI. The UT inspection confirmed visual inspection information and concluded that this weld flaw has not propagated since it was initially examined during D3R14. General Electric performed a flaw evaluation in accordance with BWRVI P-1 8 that accepts this weld flaw for over one additional cycle of operation.

Visual examinations were also performed of the "undemonstrated welds". Also, in anticipation of proposed changes to BWRVIP-18, the "target set" elbow (P4) welds were visually examined for "excessive grinding". These welds are typically UT examined only.

Dresden Road, Morris, IL60450 Section I1 Scope of Inspection Attachment A Summary of Vessel Interior Examinations BWRVIP Inspections BWRVIP-41 inspection recommendations for Jet Pump inspections were continued during D3R17, the second inspection in the six year inspection cycle. High priority inspections were performed on four DF-2 welds. Medium priority inspections of five RS-10 welds were also performed. Dresden station is on track for completion of the first cycle during D3R18. No indications were identified.

BWRVIP-47 inspection recommendations were completed for the first inspection cycle 5% sample of control rod drive guide tubes. No indications were identified.

Steam Dryer EPU Inspections Steam Dryer inspections were performed as committed during EPU discussions with ACRS. No indications were identified. Additional dryer component surfaces were examined to verify that the conditions identified on the failed Quad Cities Unit 2 dryer were not present on the Dresden Unit 3 dryer. A repair was installed on the skirt to preclude the possibility of a failure under uprate flow conditions as occurred at Quad Cities.

SIL Recommended Inspections The shroud access hole covers (AHCs) on Dresden Unit 3 were last examined during D3R13. No inoications have ever been identified on the D3 AHCs. As a result, a preemptive repair as was performed on D2 has not been installed on Dresden Unit 3. A recent revision to SIL 462 necessitated an EVT-1 examination of these welds during this outage. No indications were identified.
