Fuel Cycle 23: 11-23-2004 To 06-06-2006 During the 2006 Prairie Island Nuclear Generating Plant (PINGP) Unit 1 refueling outage, an inservice inspection (IS!) examination for the first period of the fourth interval was conducted. Enclosure 1 is a copy of the 151 examination summary report for this period.

The summary report is being submitted in accordance with the PINGP American Society of Mechanical Engineers (ASME) Code Section Xl 181 Program and is intended to satisfy the inspection reporting requirements contained in IWA-6230 of the ASME Boiler and Pressure Vessel Code.

The report identifies components examined, the examination methods used, the examination number, and summarizes the results. All anomalies were either corrected or an engineering evaluation was performed to accept "as-is" conditions. A description of the corrective work and the corresponding work request numbers are provided in the ASME Section Xl Repair/Replacement portion of the report.

SUMMARY

REPORT Section 1. Discussion

1.0 INTRODUCTION

This summary report identifies the components examined, the examination methods used, the examination number and summarizes the examination results performed during the I1st period of the 4th interval, unit 1 fuel cycle 23. The 4th inspection interval is based on the examination requirements of the ASME Boiler and Pressure Vessel Code Section XI, 1998 Edition with 2000 Addenda.

2.0 PERSONNEL Visual and nondestructive examinations were performed by Nuclear Management Company, Lambert Macgill and Thomas (LMT), Westinghouse, Wesdyne and Zetec Inc.

The Hartford Steam Boiler Inspection and Insurance Company of Connecticut, provided the Authorized Inspection services. Examination personnel certifications are maintained on file by Nuclear Management Company.

3.0 INSPECTION

SUMMARY

Examination results indicate that plant system's integrity has been maintained.

Section 3 contains the listing of ISI examinations. Per IWA-6220(f), the number and percentage of examinations or tests completed during the outage should be reported in the NIS-1 report. This outage is the first outage of the first period of interval 4. The examinations are scheduled in accordance with IWA-2432. Since we have an additional outage remaining in the period, the percentage of components and categories do not exceed those as stated in Table IWB-2412-1. The number and percentage of examinations or tests for the first period will be reported in the next NIS-1I report.

Section 4 contains the Class MC components examined, the examination number, and summary of the examination results performed during unit 1 cycle 23. The first interval, September 9, 1996 to May 8, 2008 is based on the examination requirements of ASME Section XI 1992 Edition and 1992 Addenda, and 10 CFR5O.55a dated Tuesday, September 30, 1997.

Section 5 contains the pressure test results. All indications of leakage were evaluated and corrective measures performecd as required by IWB-3 142, IWC-3 132 and IWA-5250.

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 1 CYCLE 23

SUMMARY

REPORT IWE Indications Requiring Reporting Plates S-94 and S-104 metal corrosion During the general visual examination of the containment liner per SP 1277, an area of corrosion was found spanning two plates along a weld on the containment vessel. Plates S-94 and S- 104 showed light surface corrosion with each having about a 4"x4' strip on each plate. This corrosion is on the surface and is light with no pitting being exhibited.

This type of corrosion does not affect the structural integrity of the containment structure.

The most probable cause for the corrosion is a thin coat of paint. Due to its location spanning a circ weld it will be scheduled for a follow up inspection during the I1R25 outage. No other actions are required at this time. This area was recorded during the containment coatings inspection and will be added to the list of areas that should be repaired during the next outage.

Plates S-136, S-147 and S-168 peeling coating Areas of peeling paint were identified during inspections required by the Containment Inspection Program. The following components have identified peeling paint:

Plate # Summar # Inspection Report S-136 400164 2006V046 S-147 400176 2006VO47 S-168 400197 2006V048 Peeling paint meets the acceptance standard for an indication per IWE-35 10. The Coatings/IWE Program Engineer inspected the indications using binoculars to further evaluate the condition. The inspection revealed that the top coat of the coating system is peeling away from the primer. The zinc primer coat is in place and adequately adhered to the substrate. There is no rust or any other signs of degradation of the base metal that would bring the structural integrity into question. The peeling iscaused by inadequate bonding of the top coat of paint with the primer coat. The primer coat isenough to protect the substrate from corrosion.

Because this is a coating degradation issue only with no affects on the substrate, no additional or successive inspections are required. These areas of coating degradation will documented by the Safety Related Coatings Program and recorded inaccordance with the requirements of SP 1834, Unit I Containment Coating Inspection.

SUMMARY

REPORT Equipment Hatch Bolting Summary Number 40567 1, Component BI The Equipment Hatch closing system includes swing bolts which are held in by pins.

The pins are secured in place by cotter pins. Inspection report 2006V070 identified that the pins were too short to accommodate both the required washers and cotter pins. New pins were fabricated and installed under WO 153518. The Equipment Hatch is the only penetration that is secured in place using swing bolts that require pins. All other flanged penetrations have a standard bolted flange design that do not use swing bolts. No other penetration could have pins that are too short. No additional inspections are required.

SUMMARY

REPORT Boric Acid Leakage Identified at Bolted Connections During the performance of these pressure tests, fourteen (14) components were identified as having minor boric acid leakage. In each instance the leakage was stopped and Code Case N-566-1 "Corrective Action for Leakage Identified at Bolted Connections" evaluations were performed. The following items were considered in these evaluations:

The number and service age of the bolts;

Bolt and component material;

Corrosiveness of product fluids;

Leakage location and system fuinction;

Leakage history at the connection or other system components;

Visual examination of corrosion at the assembled connection.

The associated components were evaluated and found to be acceptable for continued use.

These locations are recorded and monitored in the Prairie Island boric acid corrosion control program.
