SECTION A INTRODUCTION

SECTION A INTRODUCTION Inservice inspection (1SI) 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 I was completed during the twelfth refueling outage from March through May, 2004. The DCPP Unit 1 twelfth refueling outage (lR12) was the first outage in the third period within the second 10-year ISI interval.

In addition to the ASME Code examinations reported here, a 100% bare metal examination was conducted on the reactor vessel top head penetration nozzles. The reactor bottom head penetration nozzles also received a visual examination. No evidence of boric acid leakage was found. Regional NRC staff reviewed these examinations, and 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. An introduction is provided in Section A. Section B contains the completed ASME Code Data Report Form NIS-1 for Class I 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 I. and 2 systems conducted during the period following IRi 1, and up to and including IR12, are reported in Section E.

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

Section G of this report, Repairs and Replacements, contains the completed ASME Code Data Report Form NIS-2 for those IR12 work packages closed prior to July 8, 2004 and for any pre-1R12 work packages closed after July 1, 2002. NIS-2 reports for IR12 work packages that are closed after July 7, 2004 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.

Containment exams are reported in Section H.

Augmented exams are reported in Section I.
