Enclosure PG&E Letter DCL-1 1-093 SECTION A INTRODUCTION Inservice inspection (ISI) 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 sixteenth refueling outage from May to June, 2011.

The DCPP Unit 2 sixteenth refueling outage (2R16) was the first outage in the second period within the third 10-year ISI interval.

2R16 exams were scheduled and performed as required by ASME XI, 2001 Edition thru 2003 addenda, as modified by 10CFR 50.55a.

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 I 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.

Included in section C (Class-1 piping) are inspections to satisfy MRP-146 and MRP-139.

The volumetric exams performed as per MRP-139 satisfy the exam requirements of Code Case N-722.

Containment (IWE / IWL) exams are reported in section E System pressure tests on Class 1 and 2 systems conducted during the period following Unit 2 fifteenth refueling outage (2R15), up to and through 2R16, are reported in Section F.

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

Preservice 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 2R16 work packages closed prior to or on July 05, 2011 and for any work packages closed after December 10, 2009. NIS-2 reports for 2R1 6 work packages that are closed after*July 05, 2011 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.
