1 Darlington Refurbishment Project Update Darlington Community Advisory Council October 7, 2014

2 OPG/Government Joint Objectives for Darlington Refurbishment Provide 30 years of GHG free base-load energy from high performing asset. Minimize ratepayer impact and taxpayer exposure. Support the Ontario nuclear industry, including its supply chain, and grow Ontario s capability to support nuclear industry. Make fact-based decisions as we proceed, to maintain high comfort level that project continues to meet business objectives. Maintain community and stakeholder support with open, transparent reporting and interaction. 2

3 PHASE 1 Initiation Phase SCOPE OF WORK Initial determination of refurbishment scope through completion of: -Technical assessments of all major components -Condition assessments of balance of plant components -Initiation of regulatory processes; Integrated Safety Review and Environmental Assessment Develop reference plans for cost and schedule Complete economic feasibility assessment Establish project management approach and governance Establish overall contracting strategy OPG Board and Shareholder agree with recommendation to proceed with preliminary planning within the Definition Phase of the project Darlington Refurbishment: Phased Project Management Execution Preparation Phase PHASE 2 SCOPE OF WORK Obtain regulatory approvals: -Environmental Assessment -Integrated Safety Review -Integrated Implementation Plan Implement project management and oversight Complete infrastructure upgrades, i.e. Darlington Energy Complex Implement safety improvements Award major contracts Finalize project scope and complete engineering work Procure long lead materials Complete unit prerequisite work Construct reactor mock-up and fabricate and test tooling Develop release quality cost and schedule estimate Obtain all permits and licences Mobilize and train Trades staff PHASE 3 Outage Execution Phase SCOPE OF WORK Unit shutdown and defueling Island unit and lay up systems Execute all refurbishment scope: -Reactor components -Fuel handling systems -Turbine / generator -Steam generators -Balance of plant Meet all regulatory commitments Plant maintenance and inspection activities Manage plant configuration Load fuel Commissioning Unit start-up Apply lessons learned to subsequent unit refurbishments Project close-out Q2 2014R 3

4 Regulatory Approvals: Transparent Disclosure Canadian Nuclear Safety Commission (CNSC) July CNSC approved Darlington s request for a extension to current operating licence to December Public hearing on longer term licence application will take place Summer and Fall This year: Stakeholder sessions on licence application. New hearing webpage with documentation posted. Ontario Energy Board (OEB) Application Refurbishment costs very small percentage of OPG s rate application. Proactive and transparent disclosure of contracting strategies. Aligned with the principles stated in the Government of Ontario s Long Term Energy Plan for nuclear refurbishment. 4

5 Safe and Efficient Worksite Access Improved local traffic flow and worksite access: New Holt Road/401 roundabouts and realignment of the South Service and Holt Roads. Separate access for Operations (Holt Road) and Refurbishment (Park Road) workers. New parking lot near the Refurbishment Project Office provides direct and nearby access to the work site. RPO separate entrance ensures no conflict of time or space with operations staff. 5

6 6 Refurbishment Project Office Secure entry point for Refurbishment workers. Go straight to the refurbishment island job site, punch the clock, begin work at the set start time. Vehicle Screening Facility Expedites vehicle traffic through security into the plant. Worksite Improvements Higher priority vehicles bypass traffic queues during periods of high construction traffic volume. RFR Island Support Annex RFR office, meeting and shop space. Perform pre-rfr fabrication and preparatory work activities. Retube Waste Processing Building Remote volume reduction of components. Minimizes interferences/disruption at reactor face. Site Services (Water and Sewer; Electrical Power Distribution System) Assures workers have a safe environment and facilities needed to do the work.

7 Facilities and Infrastructure: Environmental Initiatives Excavation and Soil Management Excavated soil is tested Conventional landfill Licensed facility Controlled area for drying (tritium) As of September 2014, approximately 10,000 cubic metres of soil has been dried, sampled and, if suitable, sent off-site to conventional landfill. Excavation and foundation work for the new D2O storage facility 7

8 Tooling and Warehousing Tooling: Retube tooling platform delivered September, All tooling designed, prototypes manufactured and delivered to DEC by December Warehousing: 65,000 square feet of space available. Work ongoing to establish shelving, storage, clean room for pre-assembly of RFR components. 8

9 Fuel Handling Project GE-Hitachi designed, manufactured, supplied key parts: Dummy Fuel Bundles: mimic the characteristics of fuel bundles, used in a process called push defueling. FROBS prevent bypass of coolant once a channel has been defueled. 9

10 Turbine Generator Project OPG staff interact with a life size, 3D model of the Hydraulic Control Rack Identify usability issues and mitigate discrepancies Incorporate user feedback in design, prior to Engineering completion and start of fabrication Prevents rework in final product 10

11 Project Cost Estimate Current project estimate is less than $10.0B (2013 overnight $): Assessments show project is economic. Work ongoing to refine estimate. Release Quality Estimate (cost and schedule) - October As of June 30, 2014, actual costs are $1Billion and include: In-service of the Darlington Energy Complex (DEC) and the R&FR Mockup Progression of all other projects. 11
