OPG Ageing Management

› Implementation of the AM at OPG is through several interfacing programs, including but not limited to the following:

› Equipment Reliability Program (e.g. System Health Reports, Plant Health Committee)

› Components and Equipment Surveillance (e.g. Strategy Manuals)

› Major Components Program (e.g. LCMPs)

› Major Programs:

› Containment LCM

› Cables LCM

› Flow Accelerated Corrosion

› Fatigue Monitoring

› Heat Transport System Ageing

› Ageing Effects in PSA

› Program Health Indices including ERI

› Integration through SHR

Bruce Power

› Overall Plant Integrated Ageing Management

› Programme – General Overview

› Ageing Management at Bruce Power is embedded in a comprehensive Asset Management Programme.

› Ageing effects of significant SSCs are managed through Condition Assessments, Technical Basis Assessments and Life Cycle Management

› Bruce Power’s Ageing Management process is designed around the INPO Standard Nuclear Performance Model.

› Bruce Power’s Ageing Management process has also considered REGDOC-2.6.3, Ageing Management and IAEA NS-G-2.12 in it’s design.

› Fuel Rods

› Spare parts key: Obsolescence issues being addressed

› PSA being updated to reflect current condition assessments

13


New Designs (Candu Energy)

› Regulation Regdoc 2.5.2 driving new build to include PLiM

› Industry Standards (INPO AP-913 Appendix G) driving new build to include Equipment Reliability

› Potential Owners demanding it be included

› New advanced (ACR) and enhanced designs (EC6, AFCR) driven in this direction.

› New designs also targeting longer design life at high capacity factors with fewer planned outages (3 years).

14


Summary

›Canadian Focus › Equipment Reliability

› Includes SPV identification and management › Move to CBM

› Several planned refurbishments

› Regulator has/is putting standards in place to govern

› Overall enhancement of plant programs is occurring

› Fleet alignment is a theme
