F-A F1.20B Component Support FW-2016-HL5013 CR 15-8877-Spring hanger (SH-V (Variable Spring Hanger) (2) FW-2016-HL5013 component was found contacting adjacent line 3"-FW-221 1-EC7. Noted damaged insulation on 3"-FW-2211-EC7.

Damaged insulation was removed to verify 5" clearance distance from centerline of 3"FW-2052-AA2 to lead edge of hanger rod no adjustment required to component support.

Insulation was corrected by allowing clearance spacing for rod hanger.

SUMMARY

REPORT for the 2RE17 INSERVICE INSPECTION of UNIT 2 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Operating.Company STP NUCLEAR OPERATING COMPANY May 2015

SCOPE COMPONENT SUPPORTS (IWF), CONTAINMENT METAL LINER (IWE), CONCRETE COMPONENTS (IWL), REPAIR AND REPLACEMENT, AND WELD INSPECTION PROGRAMS (IWB, IWC, IWD)

The examinations summarized in this report were performed in accordance with the 2004 Edition with no Addenda of the ASME Code, Section Xl that is applicable to the South Texas Project, Unit 2, third ten-year interval (10/19/2010-10/18/2020), second period (01/01/2014-12/18/2016). This report covers selected ASME Code Class 1, and 3 Systems/Components. This report is documented in accordance with the requirements of ASME Section Xl Code Case N-532-4.

Examinations and tests required by the Code are scheduled in accordance with "Inspection Program B' as defined in IWB-2412 for ASME Code Class 1 Systems/Components, IWC-2412 for ASME Code Class 2 Systems/Components and IWD-2412 for ASME Code Class 3 Systems/Components and IWF-2410, component supports.

ASME Code Class 1 components were examined as prescribed by Table IWB-2500-1 and the applicable Examination Categories, which established the examination frequency at each refueling outage. The ASME Code Class 2 Systems/Components were examined in accordance Wvith Table IWC-2500-1, Examination Categories. The ASME Code Class 3 Systems/Components were examined in accordance with Table IWD-2500-1, Examination Categories. Component Supports were examined in accordance with IWF- Table 2500-1, Examination Categories.

The Containment Metal Liner examinations summarized in this report were performed in accordance with the 2004 Edition No Addenda of the ASME Code, Section Xl, which is applicable to the South Texas Project, Unit 2, second ten-year interval (09/09/2009-09/08/2019), second period (09/09/2013-09/08/2016). This report covers selected ASME Code Class CC liner & MC Components. This report is documented in accordance with the requirements of ASME Section Xl Code Case N-532-4.

SUMMARY

REPORT for the 2RE17 INSERVICE INSPECTION of UNIT 2 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Operating Company 1/4  ;~

STP NUCLEAR OPERATING COMPANY May 2015

SCOPE COMPONENT SUPPORTS (IWF), CONTAINMENT METAL LINER (IWE), CONCRETE COMPONENTS (IWL), REPAIR AND REPLACEMENT, AND WELD INSPECTION PROGRAMS (IWB, IWC, IWD)

TFhe examinations summarized in this report were performed in accordance with the 2004 Edition with no Addenda of the ASME Code,Section XI that is applicable to the South Texas Project, Unit 2, third ten-year interval (10/19/2010-10/18/2020), second period (01/01/2014-12/18/2016). This report covers selected ASME Code Class 1, and 3 Systems/Components. This report is documented in accordance with the requirements of ASME Section Xl Code Case N-532-4.

Examinations and tests required by the Code are scheduled in accordance with "Inspection Program B" as defined in IWB-2412 for ASME Code Class 1 Systems/Components, IWC-2412 for ASME Code Class 2 Systems/Components and IWD-2412 for ASME Code Class 3 Systems/Components and IWF-2410, component supports.

ASME Code Class 1 components were examined as prescribed by Table IWB-2500-1 and the applicable Examination Categories, which established the examination frequency at each refueling outage. The ASME Code Class 2 Systems/Components were examined in accordance with Table IWC-2500-1, Examination Categories. The ASME Code Class 3 Systems/Components were examined in accordance with Table IWD-2500-1, Examination Categories. Component Supports were examined in accordance with IWF- Table 2500-1, Examination Categories.

The Containment Metal Liner examinations summarized in this report were performed in accordance with the 2004 Edition No Addenda of the ASME Code, Section Xl, which is applicable to the South Texas Project, Unit 2, second ten-year interval (09/09/2009-09/08/2019), second period (09/09/2013-09/08/2016). This report covers selected ASME Code Class CC liner & MC Components. This report is documented in accordance with the requirements of ASME Section XI Code Case N-532-4.

Examinations and tests required by the Code are scheduled in accordance with "Inspection Program B" as defined in IWE-2412 for ASME Code Class CC liner & MC Components. The Containment Metal Liner Components were examined in accordance with Table IWE-2500-1, Examination Categories.

The ASME Code Class CC components were examined during fall of 2014 as prescribed by Table IWL-2500-1; ASME 2004 Edition No addenda subsection IWL. 20th Year examinations were completed under Surveillance ST: 88000349 (OPSPO9-TD-001 Containment Tendon Test/End Anchorage and Adjustment Concrete Inspection.)
