SECTION A INTRODUCTION

SECTION A INTRODUCTION Inservice inspection (ISI) of scheduled ASME Section XI Class 1 and 2 components and their supports at Pacific Gas and Electric Company's Diablo Canyon Power Plant (DCPP) Unit 2 was completed during the thirteenth refueling outage from April through May, 2006. The DCPP Unit 2 thirteenth refueling outage (2R1 3) was the second outage in the third period within the second 10-year ISI interval. In addition to the ASME Code examinations reported here, a 100% ultrasonic examination and bare metal examination was conducted on the reactor vessel top head penetration nozzles. No evidence of damage or boric acid leakage was found. The results are on file at the plant site. This report is submitted as required by ASME Section XI, paragraph IWA-6220, 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. System pressure tests on Class 1 and 2 systems conducted during the period following 2R12, up to and including 2R13, are reported in Section E. Appendix J, Containment penetration pressure tests are reported in Section F. Preservice inspections were performed on certain components, as required after repairs or replacements. These items are detailed in Section G. Augmented examinations are reported in Section H. Section I of this report, Repairs and Replacements, contains the completed ASME Code Report Form NIS-2 for those 2R13 work packages closed prior to or on June 30, 2006 and for any pre-2R13 work packages closed after January 16, 2006. NIS-2 reports for 2R13 work packages that are closed after June 30, 2006 will be included in the next outage report. Corrective actions and work order package documentation are on file at DCPP and are referenced by work order number in the NIS-2 reports. Manufacturers' Data Reports for Nuclear/Pressure Vessels are reported in Section J.
