Refurbishment and Continued Operation of the Darlington Nuclear Generating Station

The Minister of the Environment has designated this project and the environmental assessment will continue under the former Canadian Environmental Assessment Act.

Ontario Power Generation (OPG) is proposing the refurbishment of the four reactors at the Darlington Nuclear Generating Station and the continued operation of each reactor for a period of approximately 30 years following refurbishment. Refurbishment will require that a number of major components in each reactor be inspected and serviced, including replacement as applicable, during a planned outage. A key refurbishment activity will be removal and replacement of the fuel channel assemblies and feeder pipes in the reactors. Following the planned outage for each reactor, the refurbished unit will be re-fuelled and returned to full power operation. No more than two reactors will be in refurbishment outages at any given time. Ongoing operation after refurbishment, including ancillary systems, will include routine scheduled maintenance activities and inspections. The on-site Darlington Waste Management Facility (DWMF) will be expanded (i.e., additional storage buildings) to accommodate waste from refurbishment and continued operations.
