Exelkn-Braidwood Station Unit I AlRII ISI Outage Report 1.0 INSPECTION INFORMATION 1.1 Summary Second Interval Inservice Inspections (ISI) of ASME Class 1, 2, and 3 components were conducted at Braidwood Station Unit 1 from May 3, 2003 to October 24, 2004, with the majority of these inspections being performed during the Braidwood Station Unit 1 eleventh refueling outage (Al RI 1). This outage is reflected in the Braidwood ISI schedule by the code 223 (Interval 2, Period 2, Outage 3).

The examinations were performed in accordance with the rules and regulations of Section Xl, Division 1, "Rules for Inservice Inspection of Nuclear Power Plant Components," of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, 1989 Edition, no addenda, pursuant to the requirements of Title 10, Part 50.55a of the Code of Federal Regulations (I CFR50.55a).

The Containment Inspection Program was developed and implemented in accordance with the requirements and intent of Subsections IWE and IWL of ASME Section XI, 1992 Edition through the 1992 Addenda, pursuant to the requirements of 10CFR50.55a.

In addition to the ASME Section XI requirements, certain NRC augmented ISI inspections were required during Al RI 1. The Braidwood Unit I augmented ISI examinations included:

a) Examination of the Class I pressure boundary for leakage at nominal operating pressure, in accordance with NRC Bulletin 88-05.

b) Bare Metal Visual examination of the Unit 1 pressurizer steam space nozzles in accordance with Braidwood Station response to NRC Bulletin 2004-01.

c) Visual examination of pressure retaining components above the reactor vessel head in accordance with First Revised NRC Order EA-03-009 section IV.D.

d) Bare metal visual inspection of all Unit I reactor vessel lower head instrument penetrations in accordance with the Braidwood Station response to NRC Bulletin 2003-02.

There were no significant findings associated with any of the augmented ISI examinations. Reports for these examinations have been submitted under separate transmittals when required.

1.2 Identification of Examination Requirements The Second Interval ISI Program contains the Component Selection tables.

These tables are presented in a tabular format consistent with the tables found in subsections IWB, IWC, IWD, IWE, IWF, and IWL-2500 of the ASME code. The NDE tables include the corresponding code category, item number, and Page 1-1

Certified personnel performed and evaluated all NDE. Personnel were certified to the requirements of the American Society for Non-destructive Testing SNT-TC-1A, 1984 Edition. The NDE procedures were developed and certified in conformance with ASME Section V and Xl, 1989 Edition, as applicable. In addition, ultrasonic examination personnel were qualified in accordance with ANSI/ASME CP-189, 1995.

Certified personnel performed and evaluated visual examinations (VT-1, VT-2, and VT-3) of Class 1, 2, and 3 components and supports. Personnel were certified to the requirements of the American Society for Non-destructive Testing SNT-TC-IA, 1984 Edition and/or ASME Section Xl 1989, as applicable.

Certified personnel performed and evaluated visual examinations (VT-1, VT-3, VT-1 C and VT-3C) of Containment Structures. Personnel were certified to the requirements of the ANSI/ASNT CP-1 89, 1991 revision, and/or ASME Section Xl 1992 through 1992 Addenda, as applicable.

1.5 Witness and Verification of Examination The inservice inspections were witnessed and/or verified by the Authorized Nuclear Inservice Inspectors (ANII), L. Malabanan and R. White.

In addition, the inspections were performed consistent with the Electric Power Research Institute (EPRI) PWR Steam Generator Examination Guidelines,"

Revision 6, and Nuclear Energy Institute NEI 97-06, "Steam Generator Program Guidelines," Revision 1.

The following inspections were performed during this outage:

• 100% Full Length Bobbin Coil in SG 1B

• Approximately 22% Bobbin Coil of the hot leg tubing straight sections in SGs 1A, 1C, and ID

• Approximately 15.5% Bobbin Coil of the cold leg tubing straight sections in SGs 1A, IC, and ID

• 25% +Pointm probe inspection of Hot Leg Dents and Dings > 5.0 Volts in bobbin coil signal strength

• Diagnostic +PointTM Inspections based on Bobbin Coil results

• 100% visual inspection of previously installed tube plugs

• 100% visual inspection of newly installed tube plugs The modes of tube degradation found during Al RI I were fan bar wear, lattice grid wear and foreign object wear.

As a result of the eddy current inspection of the SGs, a total of 5 tubes were removed from service by mechanical tube plugging. The 5tubes were removed from service due to having wear associated with secondary side foreign objects located at the lattice grid support structures. One tube in SG 1B had tube wear greater than the TS plugging limit of > 40%. Pursuant toTS 5.5.9.c, 'Inspection Results Classification," the 1B SG was classified as inspection category C-2. Scope expansion into the remaining three SGs was not required per TS requirements, but was recommended per the guidance provided in Page 2- 3

Braidwood Station Unit I AlRI1 ISI Outage Report the EPRI Guidelines. A scope expansion plan consisting of approximately 22% of the hot leg straight section tubing and 15.5% of the cold leg straight section tubing in each of the remaining three steam generators was developed and implemented in accordance with the guidance provided in the EPRI Guidelines. The inspection results for the 1A, IC and 1D were classified in accordance with TS 5.5.9.c as inspection category C-1. There were no scanning limitations during the eddy current examinations. The table below provides the total tube plugging history and equivalent plugging levels to-date for the Braidwood Station Unit 1 SGs. Note: The Braidwood Unit 1 steam generators were replaced during the Cycle 7 refueling outage (November 1998). No eddy current examinations were performed during the Al R09 refuel outage.

VT-3/4 IND.

Snubber IRCOl BB-B was tested outside of the sample scope. Snubber was tested for Service Life Monitoring due to seal leakage identified at ambient temperatures during AlRio. Reference IR Number 154802. During AiR11, two anomolies were Identified during functional testing. The activation / lock up value In tension was slightly below the expected value and during the pressure test the rod wiper extruded from It's position.
