Revision Summary

• Initial issue

INTRODUCTION This report represents a summary of the Inservice Inspection (ISI) activities performed at the Carolina Power and Light Company's Brunswick Steam Electric Plant (BSEP) Unit 2 during the Spring 2005 refueling outage.

The examinations and testing performed during this timeframe were for credit during the second inspection period of the Third Inspection Interval.

Examinations and testing were performed to satisfy the requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Inspection Program B, 1989 Edition with no addenda.

During the refueling outage, ASME Code Category B-D and R-A components were identified as having less than 90% coverage. A relief request will be submitted prior to the end of the Inspection Interval for examination coverage.

In accordance with requirements of Code Case N-532, which has been approved for use at the Brunswick Station, enclosed is the Owners Activity Report (OAR-I Report).

2. Some or all examinations in this category may be deferred until the end of the inspection interval.

3. Examination category B-F and B-J have been subsumed by Category R-A to reflect approval of a Class 1 Risk Informed ISI Program. This was implemented with the commencement of the Second Inspection Period and the total number of examinations for the remaining periods and interval reflect Relief Request RR-27 and NRC Safety Evaluation dated 2/17/2000.

4. The examinations under this examination category are event related. They are only required if a subject pump or valve is disassembled during a maintenance activity.

5. Item number B7.80 of this category includes a requirement to examine CRD bolting if a CRD is disassembled. In accordance with relief request RR-04 which implemented Code Case N-547, there is no longer a requirement to examine this bolting.

6. This category has only 2 items and is covered by Relief Request RR-21.

7. This category reflects adoption of code case N-409 during 2nd Inspection Period.

Surfaces In accordance with 10CFR50.55a (b)(2)(ix)(A), the inaccessible areas of the containment liner which displayed evidence of degradation are addressed below.

(1) Blistering and bulging was identified during general visual examinations in 1-X-2. As a consequence of this, engineering directed inspections were conducted on the Unit 2 Personnel Airlock Penetration Sleeve 2-X-2.

Contingency Work Order 584530 was developed prior to the outage to support inspection and repair of the liner, additionally, the Specification for Containment Structures Steel Liners, Spec. 015-001 was revised to provide a minimum design wall thickness for the life of the plant. Ultrasonic measurements were taken to assess liner thickness in areas identified as bulged. The ultrasonic measurements indicated that the liner thickness in the area of the bulging was below the expected wall thickness for the liner when compared with the design drawings. Based on the inspection results from Unit 1, wastage on the exterior surface of the Drywell Personnel Airlock penetration was attributed to surface corrosion as a result of a material defect occurring during construction.

(2) Areas of the liner which were below the minimum design wall thickness were restored to the design wall thickness specified in Spec. 015-001. W/O 584530 provided instructions for this repair.
