Enclosure SECTION A INTRODUCTION 3

Enclosure SECTION A INTRODUCTION Inservice inspection (lSI) of scheduled ASME Section XI components and their supports at Pacific Gas and Electric Company's Diablo Canyon Power Plant (DCPP) Unit 2 was completed during the seventeenth refueling outage from February to March, 2013.

The DCPP Unit 2 seventeenth refueling outage (2R17) was the second outage in the second period within the third 10-year lSI interval.

2R17 exams were scheduled and performed as required by ASME XI, 2001 Edition thru 2003 addenda, as modified by 10CFR SO.SSa.

This report is submitted as required by ASME Section XI, paragraph IWA-6240, and is organized in several sections. This introduction is Section A. Section B contains the completed ASME Code Report Form NIS-1 for Class 1 and 2 components. Sections C, and D, detail the Class 1 and 2 examinations performed, date of examination (for group items or for more than one type of examination performed, the date provided is the most recent examination date), any unusual conditions noted, corrective actions if required, and explanatory remarks.

Containment (lWE / IWL) exams are reported in section E System pressure tests on Class 1 and 2 systems conducted during the period following Unit 2 sixteenth refueling outage (2R16), up to and through 2R17, are reported in Section F.

Appendix J, Containment penetration pressure tests are reported in Section G.

Pre service inspections were performed on certain components, as required after repairs or replacements. These items are detailed in Section H.

Section I of this report, Repairs and Replacements (Class 1, 2 & 3), contains the completed ASME Code Report Form NIS-2 for those 2R17 work packages closed prior to or on April 22, 2013 and for any work packages closed after July OS, 2011. NIS-2 reports for 2R17 work packages that are closed after April 22, 2013 will be included in the next outage report. Corrective action and Order package documentation are on file at DCPP and are referenced by Order number in the NIS-2 reports.

Manufacturers' Data Reports for 'New Items' are attached behind the applicable NIS-2.
