October 2003 Inservice Inspection 200 Exelon Way, Kennett Square, PA, 19348 Unit No. 2; National Board No. N-137 Commercial Service Date: 06-09-72 Dresden Nuclear Power Station 6500 N. Dresden Road, Morris, IL 60450 Section I Introduction The eighteenth Inservice Inspection (ISI) of Dresden Unit 2 was performed during the D2R18 outage which began on October 14, 2003 and was completed on November 11, 2003. This was the final refueling outage of the unit's 3rd 10-year Inservice Inspection Interval which commenced on March 1, 1992. The third Inspection period commenced on October 1, 1999 and was completed on September 30, 2003. All of the scheduled ASME Section Xi examinations were completed on-line prior to September 30, 2003 with the exception of Examination Category B-A reactor vessel shell welds and Examination Category B-O CRD housing welds. The reactor vessel shell welds were completed during the D2R18 refuel outage in accordance with a schedular exemption. The CRD housing welds were completed during D2R1 8 in accordance with a relief request. This report summarizes the reactor vessel weld and CRD housing weld examinations completed during D2R1 8 and on-line examinations which were completed since the previous Unit 2 Summary Report (dated February 5, 2002).

The Authorized Nuclear Inservice Inspector's (ANII) services were provided by The Hartford Steam Boiler Inspection and 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, and the ASME Boiler and Pressure Vessel Code, Section Xl, 1989 Edition.

Dresden Road, Morris, IL 60450 Section 11 Scope of Inspection Abstract of Is[ and Augmented Examinations ISI and Augmented Examinations Table A contains a list of components examined on-line prior to completion of the 3rd 0-Year Inservice Inspection Interval and Examination Category B-A and B-O examinations performed during the D2R18 refuel outage. These examinations are in accordance with the Dresden Station ISI Program, Dresden Station Technical Requirements Manual, and the ASME Boiler and Pressure Vessel Code, Section Xi, 1989 Edition. Those items which were examined and met the acceptance standards of ASME Section Xi 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.

Reactor Vessel Weld (Category B-A) Examinations The Unit 2 reactor vessel shell welds are examined as required by 1 OCFR50.55(a) and ASME Section Xl. 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 B1.30, Head to Flange Weld. Two relief requests are 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 which was after the scheduled completion of the 3rd 10-year Inservice Inspection Interval. Otherwise, the entire inspection would have been required during D2R17, the last outage in the third inspection interval. The basis of this request is to allow the station to take advantage of a new inspection technology, the AIRIS 21 system, to achieve increased coverage without significantly impacting the outage.

Control Rod Housing Weld (Category B-O) Examinations The Unit 2 control rod housing welds are examined as required by ASME Section Xl. These welds are addressed under Examination Category B-O, Item number B4.10, Welds in CRD Housings. In accordance with an authorized relief request, these welds were nspected during D2R1 8 which was after the scheduled completion of the 3rd 1 0-year Inservice Inspection Interval.
