DESIGN BASIS INTEGRATION Presented By: Hiram R. Reppert Supervisor, Design Basis & Configuration Management Perry Nuclear Power Plant 8th Configuration Management Benchmarking Conference October 29 – 31, 2001 Raleigh, NC

Design Basis Integration OBJECTIVE: To show the nuclear industry the Design Basis Program in place at Perry and how it is utilized as a Configuration Management process.

Design Basis Integration Breakout # 1 Management of Calculations Calculations not cross-referenced to design inputs Calculations not updated because engineer can’t find them Breakout # 8 Design Basis Documents Effective maintenance

Design Basis Integration Configuration Management is the method or process where all three of these entities work in concert.

Design Basis Integration Calculations, Specifications, and Drawings form an integral part of Design Basis & Configuration Management

Design Basis Integration Configuration Management of Design Basis Notification upon initiation EDMS Document Administration Input into ATLAS Pending vs. Approved BLUE vs. BLACK

Design Basis Integration Configuration Management of Design Basis Contact with Responsible Engineer Scope/extent of document change ATLAS changes incorporated (Pending) Responsible Engineer review BLACK and BLUE information displayed

Design Basis Integration Configuration Management of Design Basis Upon document approval-->ATLAS is changed Text turns from BLUE to BLACK New DESIGN BASIS available immediately Previous information is archived

Design Basis Integration Configuration Management of Design Basis BLUE information alerts individual that something is changing in the document. Until new revision is approved or implemented, BLACK information is Design Basis

Design Basis Integration SUMMARY Distinguish between ‘PENDING’ (BLUE) and ‘APPROVED’ (BLACK) Design Basis Launch latest revision of document Electronic preparation, review and approval Instant Configuration Management update
