Braidwood Station Unit 1 A1R13 ISI Outage Report 4M Code N-513-1 Evaluaflon A through-wall leak of approximately initially described as one pint per minute was discovered on Line OSXO1 CF-30 (reference Issue Report 706376 dated 12/3/2007).

Code Case N-51 3-1 was invoked to address corrective actions for this identified leak.

Section 2,0(i) requires evaluations and examinations associated with use of the Code Case be documented in accordance with IWA-6300 and on the applicable data report form. This line is classified as Section Xl Class 3. Class 3 repairs and replacements and associated Code data report forms are not included into the post outage inspection summary report per IWA-6210(c), so this section has been added to the post outage inspection report to address the reporting requirements of the Code Case. The subject line Operability Evaluation 07-010 was performed to evaluate the observed leakage. The text that follows is taken from the Operability Evaluation.

A design analysis was performed per Code Case N-513-1. This Code Case provides a methodology for evaluating flaws in ASME Class 2 and 3 moderate energy piping (i.e.,

piping whose maximum operating temperature does not exceed 200 degrees F and whose maximum operating pressure does not exceed 275 psig). The structural integrity evaluation (Calculation BRDW-06Q-301 Revision 1) has determined the allowable through-wall flaw sizes based on several different uniform wall thicknesses. The analysis conservatively assumes that the entire pipe is internally thinned to the analyzed thickness.

The allowed flaw size (4.8 inches, circumferential, by 17.2 inches, axial) was determined for an average adjacent pipe wall thickness of 0.2 inches.

The UT data on the SX pipe show an average wall thickness in excess of 0.2 inches and the size of the flaw has been estimated at 1/4-inch diameter hole. Thus, the structural integrity of line OSXO1XCF-30 is maintained.

The adverse condition monitoring plan requires Engineering to be notified if the flaw increases to a 1-inch diameter in size. The implementation of this ACM ensures the flaw size remains within the boundary of the design analysis.

Flooding From an equipment operability standpoint, the leakage volume does not need to be re-routed.

The leakage volume would fill the valve pit and it would overflow to the floor slab elevation of the Circulating Water pumps. No safety related equipment that would be damaged by the overflowing water is located at this elevation.

Effects on Adjacent Equipment The leakage spray volume can reach a number of manual components; valve OSX1 1 5F and chemical feed equipment. Valve OSX115F is a manual, normally open gate valve; the water spray from the leak will not affect the required open position of the valve. This valve is not required to be manipulated by plant emergency procedures, but it does need to be closed to permit inspection of the 20 Forobay as part of procedure BwMP 3300-091.

The chemical feed components do not need manipulation in any emergency conditions, but may need to be manipulated as part of normal operating procedures. If the SX valve and the chemical feed components need to be manipulated, the flood volume inside the pit needs to be pumped-out.

Loss of SX Volume Through the Flaw The amount of leakage through the flaw is small. In addition, the through wall leakage is located on the suction side of the SX pumps; thus, the leakage flow rate does not affect the discharge flow of the SX pumps. The only impact is loss of volume from the lake.

Page 4-1

Braidwood Station Unit 1 A1R13 ISI Outage Report This limiting factor would translate in a significant leakage flow that could be tolerated as explained below.

The potential issue with losing lake volume is that the water depletion does not lower the water level as to impact the Net Positive Suction Head for the SX pumps.

The NPSH available for the SX pumps is verified acceptable in calculation #SX1 -85 and outstanding minor revisions. The NPSH available has been verified to be acceptable (Available NPSH is 44.97 ft while the required NPSH is 36 ft) assuming a water level of 588.3 ft in the Ultimate Heat Sink (This level is lower than the minimum required Technical Specification level of 590 ft). A total volume loss in excess of 3.3 million cubic ft would be needed to lower the UHS water level from 588 ft to 587 ft; this one ft reduction keeps the available NPSH adequate. A volume loss of 3.3 million cubic ft (Reference calculation ATD-109) translates in a leakage flow rate in excess of 76 ft3/min (or 571 gpm) for continuous 30 day period.

The leakage rate of the flaw has been estimated to be approximately 8 gpm. This was based on a comparison to the theoretical discharge flow value through a 1/4-inch nozzle with a head pressure of 15 psi, (34.6 ft). Note that the adverse condition-monitoring plan (ACM) was written to monitor this leakage rate on a daily basis to confirm that the conditions stay within the limitations of this operability evaluation and the pipeline structural integrity calculation. Since an increase of flaw size translates into an increase in leakage flow, the ACM requires Engineering to be notified if the flaw size increases to a one (1) inch diameter in size, which is equivalent to a leakage rate of approximately 116 gpm. This leakage rate is significant lower than the acceptable volume loss of the Ultimate Heat Sink, even if left to leak for the UHS mission time of 30 days.

Operability Based on the above arguments, the SX system remains operable with the through-wall flaw in line OSXO1CF-30.

Braidwood Station Unit 1 A1R13 ISI Outage Report 6.0 REPORT OF CONTAINMENT DEGRADATION The NRC amended 10CFR 50.55a to incorporate by reference the 1992 Edition with the 1992 Addenda of 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. 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)(viii)(C)-(E) and 10CFR 50.55a(b)(2)(ix)(A)-(D). The completed surveillances for IWL and IWE contain all the examination details along with indications recorded and their associated evaluations required by ASME Section XI.

6.1 Containment Concrete Examinations (IWL)

Unit 1 and Unit 2 IWL tendon and concrete examinations under the 20th year post tensioning surveillance began in March of 2006, and were completed in September of 2006 (prior to the A2R12 refuel outage). The Unit 1 examinations were not completed at the time the Al Ri2 IWA-6000 report was submitted. Examination results for conditions described under 10 CFR 50.55a(b)(2)(viii)(D)(1) were available for inclusion into the A1Ri2 outage summary report (ADAMS Accession Numbers ML062090368 and ML062090372).

The presence of grease leakage observed during the general visual examination was the only 10 CFR 50.55a(b)(2)(viii)(D) reportable condition identified since the last outage summary report was submitted.

One area of grease leakage was identified during the general visual of the containment surfaces (reference Issue Report 518036) and is being reported as required by 10 CFR 50.55a(b)(2)(viii)(D)(3). The location of the indication is outdoors, on the east face of the Unit 1 containment structure at the upper right hand corner of the area where the containment opening was made to support the Unit 1 steam generator replacement in 1998. The indication was detected using a telescope demonstrated in accordance with ASME Section XI. The indication is characterized as a crack running diagonally approximately 12 inches. A film of tendon grease exists adjacent to both sides of the crack. The indication was not noted during the previous examination performed in 2001.

This indication was evaluated by the site Registered Professional Engineer (RPE), who concluded the leakage has a negligible impact on the structural integrity of the containment. A follow-up examination was performed in August 2007 with no adverse changes noted. Another follow-up examination is scheduled for August 2008, tracked under ATI 518036-03.

One additional area of grease leakage that did not exist during the 2006 inspection was observed after a subsequent comparison of IWL examination results was performed in November of 2007 (reference Issue Report 696361). The location of the indication is outdoors and is located within a horizontal construction joint approximately 30 feet to the south of the lB/iC MISV Rooms, approximately 35 feet above ground level. The leakage is in the form of a film/stain within the construction joint and on the surface of the wall.

The surface area of this indication is approximately 18 inches long by six inches wide.

This leakage likely occurred during the summer months when the sheathing filler grease becomes more viscous and will propagate through small cracks or voids. This indication was evaluated by the site Registered Professional Engineer and was deemed to have a negligible impact on the structural integrity of the containment. A follow-up examination has been scheduled for August 2008, tracked under ATI 696361-02, Page 6-i

Braidwood Station Unit 1 Al Ri 3 ISI Outage Report 6.2 A1R13 Containment Metal Liner Examinations (~WE)
