On August 16, Ontario Power Generation (OPG) reported that as of June 30, 2019, the company was moving into the final stages of construction work on Unit 2 of the Darlington nuclear power plant refurbishment project. The company noted, however, that due to slower than expected installation of the reactor’s lower feeders, Unit 2 will now return to service in June 2020 as opposed to the previously anticipated restart date of February 2020. The likely four-month extension to Unit 2’s schedule is a result of delays encountered with fabrication and installation of feeder tube components, which had a cascading impact that resulted in upper, middle, and lower feeders being installed simultaneously. OPG said this confluence of events led to logistical and physical challenges with overlapping work schedules.
