1 NRC’s Component Design Bases Inspections
Donald P. Norkin U.S. Nuclear Regulatory Commission June 11-14, Richmond, VA

2 History April 29,2004 - SECY 04-0071 - Proposed Pilot
2004/ Temporary Instruction 2515/158 Vermont Yankee V.C. Summer Kewaunee Diablo Canyon May 1, SECY Pilot Results January Implement Component Design Bases Inspections

3 Component Design Bases Inspection (CDBI)
15-20 Risk Significant and Low Design Margin Components 3-5 Relatively High Risk Operator Actions 4-6 Operating Experience Issues Replaces Safety System Design and Performance Capability (SSDPC) Inspection Biennial - All Plants Will Receive CDBI Either in 2006 or 2007 Will Develop Criteria for Determining Scope of Design/Engineering Inspections After 2007

4 Significant Changes from SSDPC Inspections
Components vs. Systems, Which Impacts Licensee Document Retrieval Margin Review for Sample Selection Operating Experience Enhanced Inspection Preparation and Sample Selection Additional Week for Site Inspection Increase Use of Contractors Having Hands-On Design Experience

5 Staffing Team Leader Two Design Specialists (Typically Mechanical and Electrical Contractors) Two Regional Inspectors (Operations and Engineering) Part Time Support from Senior Reactor Analyst and Resident Inspector for Sample Selection Trainee (If Possible)

6 Schedule Week 1 On-Site Info Gathering Week 2 In-Office Prep/Sample Selection Week 3 Sample Selection/On-Site Inspection Week 4 In-Office Inspection Week 5 On-Site Inspection Week 6 or 7 On-Site Inspection/Exit Meeting

7 Insights From Pilot Inspections
Pilot CDBIs Had More Findings Per Inspection Hour Than SSDPCs More White Findings Than for SSDPCs Most Findings Involved Original Design, Corrective Actions, and Operating Procedure
