In 3 hours Darlington Unit 1 will have been running at 100% CF for 2 years straight (730 days). Will be interesting to see how long it will stay up for without a maintenance outage, I expect until after Unit 2 is back from its refurbishment at least. The current record for a CANDU, and for the longest time, any nuclear power plant was 894 days held by Pickering Unit 7. If Darlington bests that the next milestone is 962 days, a record set last year by another HWR, a 220MW unit in India which is basically a CANDU clone. On an unrelated note, our oldest operating station, Pickering, produced 23.6TWh last year, a site record marking 87% Capacity Factor from its six operating units and producing 17.2% of Ontario's electricity.
