• The overall PLiM programme is known as the Integrated Ageing Management Programme (IAMP).

• In addition to IAMP activities, a Fleet Life Cycle Management Plan has been prepared to provide integration of station ageing management activities and is updated periodically.

• Detailed ageing assessments for high importance, long life items (steam generators, fuel channels, feeders, and other reactor components) have been performed. These are usually called life cycle management (LCM) plans, and they are regularly updated and fed into station and fleet asset management and business plans. These define the required inspection and maintenance activities during station outages.

• Condition assessments have been performed at the component, system and plant level to varying degrees at OPG stations. Depending on the facility, the current focus ranges from extending the scope of condition assessments to completing assessments for the components/systems initially identified as high importance.

• Condition assessments are inputs to business planning and asset management processes, as well as to system and component health programmes.

• Replaceable and short life components are actively managed by predictive and preventive maintenance programmes.

• OPG is rapidly developing LCM at its plants — it is considered central to long term business success. Effort is concentrated on completion and improvement of LCM plans for all critical systems, structures and components.

• The importance of closer linkages between LCM and both business plans and the R&D programme, is recognized.

• Pickering U1 and 4 have been refurbished & restarted. A decision has been made not to refurbish U2 and U3. These Units are being placed into safe storage.
