The majority of these inspections were performed during the Braidwood Station Unit 2 fifteenth refueling outage (A2R1 5). This report also contains the results of the remaining pressure tests that were not completed prior to submittal of the previous A2R1 4 outage report.For the Third Interval, 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, 2001 Edition through 2003 Addenda, pursuant to the requirements of Title 10, Part 50.55a of the Code of Federal Regulations (10CFR50.55a).

The Containment Inspection Program was developed and implemented in accordance with the requirements and intent of Subsections IWE and IWL of ASME Section Xl, 2001 Edition through the 2003 Addenda, pursuant to the requirements of 1OCFR50.55a.

In addition to the ASME Section Xl requirements, certain NRC or industry augmented inspections were completed during A2R15. The Braidwood Unit 2 augmented examinations included: a) Examination of the Class 1 pressure boundary for leakage at nominal operating pressure, in accordance with Generic Letter 88-05.b) Examination of the 2B reactor coolant pump motor flywheel in accordance with Regulatory Guide 1.14 and Technical Specification 5.5.7.c) Examination of welds in accordance with Materials Reliability Project MRP-139, "Primary System Piping Butt Weld Inspection and Evaluation Guideline" and MRP-192, "Assessment of RHR Mixing Tee Thermal Fatigue in PWR Plants".d) Reinspection of all six pressurizer nozzle-to-safe end full structural overlays in accordance with ASME Section Xl Nonmandatory Appendix Q and Second Interval Relief Request 12R-48.The only documented indication requiring further evaluation was observed during the augmented inspections for MRP-192 in a tee-to-pipe circumferential weld. This indication was attributed to original construction and was not characterized as service-induced (i.e., thermal fatigue craze cracking).

The indication was accepted for continued service in accordance with IWB-3600 evaluation methods.Page 1-1 Exel .n-Braidwood Station Unit 2 A2R15 ISI Outage Report 1.2 Identification of Examination Requirements The Third Interval ISI Program contains the applicable Component Selection tables.

Through-wall sizing of the indication was performed using the Absolute Arrival Time Technique (AATT) which used 45, 60, and 70 degree shear wave scans (reference Data Sheet A2R15-UT-029).

The flaw sized as 0.70" long with a remaining ligament of 0.185". IR 1208120 was initiated to document the flaw which was evaluated as acceptable for continued service under EC 384283. Although weld is not subject to ASME Section XI volumetric examinations due to wall thickness, weld will be examined during the next inspection period in accordance with IWC-2420(b) as tracked by ATI 1208120-02.

.C-H C07.10 2RH-12 F-3-1 (C-H) VT-2 NRI FLANGED CONNECTION (12 STUDS)EXAMINE DUE TO RI IDENTIFIED DURING THE PREVIOUS EXAM.Page 3-54 Exea! n Braidwood Station Unit 2 A2R15 ISI Outage Report 4.0 REPORT OF CONTAINMENT DEGRADATION Containment inspections are performed in accordance with Subsection IWE (Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled Power Plants) and Subsection IWL (Requirements for Class CC Components of Light-Water Cooled Power Plants) of ASME Section Xl, Division 1, with specified modifications and limitations in 10 CFR 50.55a. The following sections are included in the Inservice Inspection Summary report as required by IWA-6000 of ASME Section Xl to meet the reporting conditions specified in 10CFR 50.55a(b)(2)(ix)(A)(1) through (3).The following discusses examinations performed in accordance with ASME Section XI, Subsections IWE and IWL respectively.

4.1 A2R15 Containment Metal Liner Examinations (IWE)The Third Interval First Period Class MC General Visual Examinations were completed during A2R15. All indications identified during the General Visual Examinations were reviewed and accepted as is by the Responsible Individual as defined in ASME Section XI.The completed surveillances for IWE contain all the examination details along with indications recorded and their associated evaluations required by ASME Section XI.The following discusses augmented exams performed under the containment moisture barrier.Augmented Section XI IWE examinations of the Class CC liner examinations for the Third Interval were performed in accordance with the requirements of ASME Section XI, Table IWE-2500-1, Category E-C, Containment Surfaces Requiring Augmented Examination.

Exelon Procedures ER-AA-330-007, "Visual Examination of ASME Section X1 Class MC Surfaces and Class CC Liners", ER-AA-335-018, "Detailed, General Visual, VT-1, VT-1 C, VT-3 and VT-3C, Visual Examination of ASME Class MC and CC Containment Surfaces and Components", and ER-AA-335-004 "Ultrasonic Measurement Of Material Thickness and Interfering Conditions" were used to perform the examinations.

Six sections of the containment moisture barrier were removed for the purpose of performing augmented examinations of the containment liner surface. These examinations were required due to identification of degradation during past examinations.

The results of the examinations revealed no evidence of degradation that had not been identified during past examinations.

The conditions remained unchanged with no evidence of additional degradation.

A description of the type and estimated extent of degradation, and the conditions that led to the degradation

[10CFR 50.55a(b)(2)(ix)(A)(1)]:

The results of the examinations revealed no evidence of degradation that had not been identified and evaluated as acceptable by the Responsible Individual during past Page 4-1 ExeI ~n Braidwood Station Unit 2 A2R15 ISI Outage Report examinations.

The conditions remained unchanged.

The previous evaluation was documented under Engineering Change 377614.Extent of condition:

No extent of condition augmented examinations were required during A2R1 5.Description of the conditions that led to the degradation:

As originally identified during the A2R08 examinations, the identified liner degradation was a result of moisture barrier aging and mechanical damage of the moisture barrier that occurred during maintenance activities.

The damage of the moisture barrier resulted in a leakage path for water impingement on the liner. The primary source of the water is condensation from the containment fan cooling units. The entire moisture barrier was removed, examinations performed, areas coated and the moisture barrier was replaced during A2R08.Evaluation of each area, and the result of the evaluation

[1 OCFR 50.55a(b)(2)(ix)(A)(2)]:

The results of the A2R15 examinations revealed no evidence of degradation that had not been identified and evaluated as acceptable by the Responsible Individual during past examinations.

The conditions remained unchanged.

The previous evaluation was documented under Engineering Change 377614.Description of Necessary Corrective Actions Completed[1 OCFR 50.55a(b)(2)(ix)(A)(3)]:

Proposed Actions for A2R1 6: Additional VT-1 (Detailed Visual) and ultrasonic thickness examinations are scheduled in A2R1 6 refueling outage to examine the condition of the liner plate below the moisture barrier at the three locations.

These three locations were examined during A2R15 with no evidence of changes from conditions identified during the previous augmented examinations.

They are being scheduled for successive exams during A2R16.Conclusions/Findings Based on the conclusions of the previous evaluation (Engineering Change Number 377614) and the fact that no additional degradation was identified during the A2R1 5 augmented examinations, the liner plate containing the degraded conditions below the moisture barrier (MB) in Unit 2 containment is acceptable and capable of performing its intended design function.4.2 A2R15 Class CC (IWL) Containment Examinations The Units 1 and 2 2 5 th Year ASME Section Xl WL Post Tensioning and Concrete examinations and tests began in June of 2011. The Post Tensioning surveillance is scheduled to be completed in September 2011 while the containment concrete examinations are scheduled to be completed in December 2011. Final reporting in Page 4-2 Exelon.Braidwood Station Unit 2 A2R15 ISI Outage Report accordance with ASME Section Xl IWL-3310 and 10CFR50.55a will be included in the IWA-6000 ISI Summary Report for Refuel Outage Al R1 6 which is currently scheduled for April 2012.At the time of preparation of this report, the presence of free water, IWL-3221.3 (a) is the only identified reportable condition.

Chemical analysis for the sheathing filler and free water are in progress.

However, results are pending. Table 4.2-1 describes the presence of free water identified for the specific tendons for available results. With the exception of the dome tendons, all locations are below grade level.Table 4.2-1 Tendon Inspection Results (As of 7/25/2011)

Sheathing filler was not discolored (indicative of moisture saturation) in the as found condition.

Note 2: No evidence of degradation or active corrosion was identified on either the anchorage components or the surrounding concrete.

However, the sheathing filler was discolored (light, cream colored which is indicative of saturation) in the as found condition.

Page 4-3 Exeln..Braidwood Station Unit 2 A2R15 ISI Outage Report Conclusions/Findings Based on the as found conditions where no degradation or active corrosion was identified on the anchorage components or surrounding concrete, there is no indication the presence of free water has resulted in any degradation of the specific tendons, post tensioning systems, or the containment structures.

At the time the A2R15 ISI Summary Report was being prepared these conditions were being evaluated in accordance with ASME Section Xl, IWL-3222.

Any additional examination results subject to reporting requirements will be incorporated into the next Braidwood Station ISI Summary Report which will be submitted within ninety days after the conclusion of the Al R16 (Spring 2012) outage.Page 4-4 Exei n.Braidwood Station Unit 2 A2R15 ISI Outage Report 5.0 NIS-1 FORM As required by IWA-6000 of Section XI, this section contains the Owner's Report for Inservice Inspections, Form NIS-1, for the inservice examination of Class 1 and Class 2 pressure retaining components.
