Enclosure 1 is a copy of the IS1 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 XI IS1 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 repairtreplacement activities and the corresponding work order numbers are provided in Section 8 of the enclosure.

SUMMARY

REPORT Section 1. Discussion

1.0 INTRODUCTION

This summary report identifies the colnponents examined, examination methods used, examination number and summarizes the results of examinations performed during the 2nd period of the 4th interval, unit 1 fuel cycle 25. 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 Xcel Energy/Northern States Power Company - Minnesota and Lambert Macgill & Thomas (LMT). The Hartford Steam Boiler Inspection and Insurance Company of Connecticut provided the Authorized Inspection services. Examination personnel certifications are maintained on file by Northern States Power Company - Minnesota.

3.0 INSPECTION

SUMMARY

Examination results indicate that plant system integrity has been maintained.

Section 3 contains the Class 1 and 2 components examined, examination number and summary of the examination results performed during unit 1 cycle 25. The number and percentage of examinations or tests completed are also included in this section as required by IWA-6220(f). There were no Class 1 or 2 examinations with service induced indications requiring scope expansion or repairlreplacement. There was one in scope Limited Examination of the 12 RHR Heat Exchanger report number 2009U039 entered into the site corrective action program AR 012 19016.

Section 4 contains the IWE Class MC components examined, the examination number and sumnlary of the examination results performed during unit 1 cycle 25. The second IWE interval (September 10,2008 to September 9,2018) is based on the examination requirements of ASME Section XI, Subsection IWA and IWE, 2001 Edition through the 2003 Addenda.

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

Pressure tests that have not yet been completed, but will be completed prior to the end of the period, will be documented in the 4thinterval, 2ndperiod, 2ndoutage 90 day summary report.

Boric Acid Leakage Identified at Bolted Connections Eighteen code class components were identified as having boric acid indications at bolted connections in cycle 25. Per the H2 Boric Acid program document, boric acid indications found as a result of a boric acid inspection are evaluated as if found during a pressure test. In each instance corrective actions were initiated and the component was evaluated and found suitable for continued service or corrected prior to continued service.

In accordance with Code Case N-566-1 "Corrective action for Leakage Identified at Bolted Connections" evaluations considered:

The number and service age of the bolts; Bolt and component material; Corrosiveness of process fluid; Leakage location and system function; Leakage history at the connection or other system components; Visual evidence of corrosion at the assembled connection.

SUMMARY

REPORT Section 6. Snubber Inservice Testing and Preservice Examinations (3 pages)

Appendix A for SP 1225 Summary description of snubber visual inspection and Functional testing for 1R26 During review of the examination summary, typographical errors were identified. These are corrected and initialed in the following pages. The error has been entered into the corrective action program (ARO 1219430).

There were a total of 23 snubbers tested in 1R26, all were functional tests. All testing was SAT. Eighteen of the twenty-three were Basic-PSA hydraulic snubbers, these snubbers had spares rebuilt and tested SAT prior to installation. The Basic-PSA snubbers that were removed were tested in the as found condition and all were also SAT. There was one ITT Grinnel snubber that was tested, rebuilt and then re-installed, which passed functional testing as well. There were two Paul Monroe snubbers that were functionally tested SAT and re-installed. Finally two steam generator valve blocks were replaced with re-built spares, all testing the pre-install of the rebuilt and the as found of the valve blocks removed were tested SAT. There was no scope expansion from failed testing on sample population during 1R26. Most of the testing was performed by a Basic-PSA field representative, with a few tests performed by in-house maintenance after Basic-PSA field rep departure.

The visual inspections SP 1171 and TP 1535 were performed by LMT. There was no scope expansions from the conditions found on these inspections. All cylinders had hydraulic fluid and issues identified during the visual inspections, as evidence of leaking, were inspected by Snubber Engineer and all instances did not depict a failure. All snubbers had acceptable level of fluid. Any leaking identified was attributed to fluid from overfull reservoirs and thermal movement. Those snubbers identified during the inspections with no movement or rotation, were inspected by the snubber engineer and those that were accessible, rotation and movement was restored. The snubbers that were inaccessible were not inspected. No snubbers were found locked up.

Seven snubbers were identified as missing its ID tag. AR 01204801 was initiated to capture and correct this at next opportunity.
