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 twelfth refueling outage from October through December, 2004. The DCPP Unit 2 twelfth refueling outage (2R12) 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% ultrasonic examination and bare metal visual examination was conducted on the reactor vessel top head penetration nozzles. The reactor bottom head penetration nozzles also received a 100 % bare metal visual examination. No evidence of boric acid leakage was found.

These examinations were reviewed by regional NRC staff, 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. This introduction is Section A. Section B contains the completed ASME Code Report Form NIS-I 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 2R1., and up to and including 2R12, 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 Report Form NIS-2 for those 2R12 work packages closed prior to or on January 16, 2005 and for any pre-2R12 work packages closed after April 25, 2003. NIS-2 reports for 2R12 work packages that are closed after January 16, 2005 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.
