The Darlington project involves the refurbishment of the four reactors at the DNGS to enable the continued operations for about 25 to 30 more years. Refurbishment requires the replacement of a number of major components when the reactor is not operating. In addition, other components will be inspected, serviced and, if necessary, replaced. Following the refurbishment of each reactor, the units will be refuelled, tested and returned to full power operation. Ongoing operation after refurbishment will include routine scheduled maintenance activities and inspections.
A refurbished Darlington station will provide 3,500 MW of electricity. OPG adds it will create employment, business and supplier opportunities, and increased municipal revenue.
