Following the report, the federal government approved the Environmental Assessment. The audit office also flagged a shortage of skilled trades, a risk that it warned could prompt delays, especially during the 2020 outage season, when OPG would be in competition with other nuclear plants. [16] Discussion of who is to blame for the costs and subsequent debts associated with Darlington often arise during provincial election campaigns, and are often mentioned in anti-nuclear literature.[17]. In May 2018, the installation phase began. [12] A year-long period of public hearings and study by an Ontario government all-party committee finished in 1986 with the decision to proceed with the project, which had then risen to $7 billion in actual and committed costs. “Each fuel channel requires a fuel channel subassembly, consisting of a pressure tube made of zirconium, two stainless steel end fittings, and four annulus spacers, which play a critical role in maintaining the gap between the pressure tube and calandria tube. Preparing for Reactor Component Removal. Critically, it also involved removing the unit’s 960 feeder pipes, which carry the coolant required to cool nuclear fuel. Along with these new components, OPG notably also added a third, more robust emergency power generator and updated fire protection systems. The station is the largest employer in Bruce County, with over 4000 workers. When construction of all four units at the 3.5-GW Darlington Nuclear Generating Station in Clarington, Ontario, was deemed complete in 1990, the project was hailed for deploying a larger 878-MW commercial model of the CANDU (CANadian Deuterium Uranium) system. News & Technology for the Global Energy Industry. It posited, presciently, that extending the units’ useful lives to 2055 would give Ontario a foothold in what it saw was relentless movement toward decarbonization. Watts Bar 2, which entered commercial service in 2016, was the first new reactor added since 1996. The facility was opened in 2007, reportedly on schedule and on budget.
