OPG’s Pickering Nuclear Power Plant is due to cease commercial operations in 2024 OPG has decided on a deferred decommissioning approach and will implement a building endstate strategy to maintain the plant in storage with surveillance (SwS) for approximately 30 years. Candesco division of Kinectrics Inc. carried out a technical assessment of various hypothetical Endstate conditions to identify opportunities and challenges in reducing the operational footprint of the station while maintaining the facility out-of-servicebuildings and structures in a safe, stable condition until dismantling and demolition activities would be undertaken.

Important aspects of this assessment include:
• Using relevant codes and standards and reviewing OPEX to validate the building endstate strategy (Referred to henceforth as the “Strategy”).
• Identifying the minimum inspection, monitoring and maintenance requirements for buildings during SwS.
• Understanding the lifecycle cost of the Strategy and identifying reasonably foreseeable complications that might arise during the SwS or subsequent phases.
• Minimizing any new hazards resulting from out-of-service buildings
