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 repair/replacement activities and the corresponding work order numbers are provided in Section 8 of the enclosure.

1.0 INTRODUCTION

This suininary report identifies the coinponents exail~ined, exanlination n~etl~ods used, the exainination n~tinber and summarizes the results of exaininations perfoilned during the 2nd outage, 2nd period, 4th inteival for unit 1 fitel cycle 26. The 4th illspection interval is based on tlle exainination requirements of the ASME Boiler and Pressure Vessel Code Section XI, 1998 Edition wit11 2000 Addenda, with liinitations and modifications as required by Title 10 of the Code of Federal Regulation, Pait 50.55a. 2.0 PERSONNEL Visual and nondesti~tctive exaininations were perfoilned by Xcel Energymorthern States Power Coinpany - Miililesota and Lainbert Macgill & Tl~oinas (LMT). The Hartford Steain Boiler Inspection and Insurance Colnpany of Coililecticut provided the Authorized Ii~spection services.

Examination persolme1 certifications are inaintained on file by Noi-tllem States Power Company - Minnesota. 3.0 INSPECTION

SUMMARY

Exainiilatioil results indicate that plant system integrity has been maintained. Section 3 lists the Class 1 and Class 2 coinponents examined, exainination nunlber and stununary of the examination results perfoilned during unit 1 cycle 26. The ntuinber and percentage of exaininations or tests coinpleted are also included in this section as required by IWA-6220(f).

Tl~ere were three Class 1 exaininations wit11 indications accepted by corrective measures.

One iildication was a loose n~~t on a lateral s~~pport (AR128393 0). Two were linear indications on piping welded attachments (AR1285 15 1 and AR1287563).

Additional and successive exaininations were perfoimed and sched~tled as required.

There were no Limited Exaininations requiring a relief request. Section 4 contains the IWE Class MC coinponents exanlined, the examination ilumber and suininary of the exainination results perfol-riled during unit 1 cycle 26. The second IWE interval (Septeinber 10, 2008 to September 9,2018) is based on the exainination requirements of ASME Section XI, S~tbsection IWA and IWE, 2001 Edition tluougl~ the 2003 Addenda with liinitations and illodifications as required by Title 10 of the Code of Federal Regulation, Part 50.55a. The number and percentage of IWE exaininations are also included in this sectioil as required by IWA-6220(f).

There were no IWE indications that required repair/replacemeilt, nor successive examinations, nor auginented exaininations.

There were no conditions in accessible areas that could indicate the presence of or result in degradation to inaccessible areas.

Section 5 coiltaiils a summary of sclleduled pressure tests. All iildications of leakage were evaluated and coi-sective ineasures performed as required by IWB-3 142, IWC-3 132 and IWA-5250. Pressure tests that have not yet been coinpleted, but will be coinpleted prior to the end of the period are noted as scl~eduled.

Sectioil 6 coiltains the Silubber illspection results. There were no visual failures of safety-related snubbers. All silubbers that under went functional testing had satisfactory results. Section 7 addresses the Eddy C~usrent exainination results of the 11 and 12 Steam Generators tubes. Section 8 contains 42 Repair/Replacemei~t activities conlpleted under the 4th hterval during the unit 1 cycle 26.

4.0 EXAMINATON REPORTS, EQUIPMENT AND MATERIALS The iilseivice inspection reports ill Sectioils 3 and 4 contain references to procedures, equipment, and illaterials used to conlplete the specific exaininations.

Copies of the exainiilatioil reports, exanlination procedures, and equipnleilt records are available froin Nortl~eill States Power Coinpany Miimesota.

SUMMARY

REPORT Section 4. IWE Exa~llinations (1 page attached)

The following table suillinarizes the IWE iilspectiolls perfornled in cycle 26. Inspections are listed by class, category and site summary number.

The secoild IWE interval ( Septenlber 10, 2008 tlwough September 9,2018) is based on the examillation requiremeilts of the 2001 Edition wit11 2003 Addenda of the Anlerican Society of Mecl~anical Engilleers (ASME) Boiler and Pressure Vessel Code Section XI with liillitations and illodifications as required by Title 10 of the Code of Federal Regulation, Part 50.55a. As such, there is only one category (E-A) and two item nuinbers (E1.11 and E1.30) in scope for the first IWE period.

There are cuneiltly no surfaces requiring augilleilted exalllinatioil under category E-C.

T11ere were no relevant iildications in the first period (9/10/08 - 1/9/12) examinations.

The nr~mber and percentage of examinatioils or tests colllpleted are included in this section as required by IWA-6220(f).

There was no iildicatioil of ref~~eling cavity lealtage or other coilditioils detected in cycle 26 that would require evaluatioil in accordance wit11 1 OCFR 50.55a (b)(2)(ix)(A).

SUMMARY

REPORT Section 6. Snttbber Inservice Testing and Preservice Exailiinations (3 pages attached)

Appendix A for SP 1225 Summary description of Snubber visual inspection and Functional testing for 1R27 There were a total of 21 snubbers scheduled for testing in 1R27. All functional tests were SAT.. Seventeen of the twenty-one 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 removed, tested and then reinstalled, which passed functional testing as well. There was one Paul Monroe snubber that was functionally tested SAT and reinstalled. Finally two steam generator valve blocks were replaced with rebuilt spares.

All valve blocks were tested SAT. There was no scope expansion from failed testing on sample population during 1R27. 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 representative depal-ture.

The visual inspections SP 1 17 1 and TP 1535 were performed by LMT. 1-CH-78, was found with no fluid and evidence of seal failure. 1-CH-78 was replaced with a pretested spare per WO#430112.

This snubber is a non safety related snubber and is not part of the sample population.

No expanded scope required due to failure (AR# 01283787).

The snubber failed the drag test and the functional test as it was unable to move (locked up) (AR# 1288787). This will be noted and this location will be tested in lR28 in accordance with the snubber program (ref:

H20, section 5.3.4)(WR#68793).

This snubber is a 2 ?4 x 5 Basic PSA snubber installed in Oct 1997. The piping system is non safety related, so no functionality evaluation is required. This piping system has a thermal growth of W @ snubber which would put minimal stress on the piping system due to the snubbers inability to move (ref drawing:

XH- 106-15872). Based on the small thermal growth the stress transferred to the piping system would be considered minimal taking deadband into account. Other issues identified during the visual inspections were addressed by performing minor maintenance on the snubbers.

Snubbers that did not have an acceptable level of fluid or had other minor issues were corrected per WO#'s 4301 12,430151,431063-431066

& 43 1350-43 1357 (ref: AR# 01286523). The snubbers that were inaccessible were not inspected. Several snubbers were identified as missing its ID tag. AR 01284426 & 1285735 were initiated to make labels for those snubbers.

Some snubbers were not installed in accordance with the snubber drawing (e.g.bac1ward).

Those snubbers were orientated with the vent cap in the uppermost position, which is in accordance with the snubber program but in conflict with the drawings. Those snubbers are fully capable of performing their safety function in this configuration. During snubber replacement, all snubber paddles and clevises spherical bearings were cleaned and coated with neverseez in accordance with maintenance general practice.

All snubbers removed from service due to service life testing or due to interferences from other work were VT- 3 inspected.
