Toronto Star The first reactor to be refurbished was Unit 2. [13] The final cost was $14.4 billion CAD, almost double the initial construction budget. 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. [28], In February 2016, the Federal Minister of Environment and Climate Change delayed a decision on OPG’s DGR, causing a pause in the timeline for the environmental assessment decision to be issued. Courtesy: OPG, “The integrated team undertook more than 765,000 training hours in the project’s leading-edge mock-up and training facility to safely shut down, defuel, disassemble and reconstruct the reactor,” OPG said. In May 2018, the installation phase began. By June 2019, the team had inspected fuel bundles that were sequenced and packed by BWXT, and were readying for fuel load. OPG, notably, selected the joint venture through a competitive bidding process in 2015 after terminating a contract with another company, which it had hired in 2013 to build a heavy-water storage and drum handling facility (a major component that is used to safely store and process radioactive heavy water that is extracted from reactor units as they are being refurbished). Once built, nuclear plants generate enormous amounts of steady electricity, and hence enormous amounts of steady revenue. In 2006, OPG started the federal approvals process to build new nuclear units at the site of its Darlington Nuclear Station. According to the Conference Board of Canada, the $12.8 billion investment will generate $14.9 billion in economic benefits to Ontario, including thousands of construction jobs at Darlington and at some 60 Ontario companies supplying components for the work. Darlington Nuclear Generating Station Located in the Municipality of Clarington in Durham Region (70 km east of Toronto), Ontario Power Generation’s Darlington Nuclear Generating Station is a four-unit facility responsible for generating over 20% of Ontario’s electricity needs, which is … These storage buildings will either be a new independent building built on the site or an expansion of the existing darlington waste management facility. Work then progressed into assembly of the unit’s 480 fuel channels. [30] The Nuclear Waste Management Organization is seeking a site in Canada for a permanent repository for used fuel from all of Canada's nuclear reactors. Critically, it also involved removing the unit’s 960 feeder pipes, which carry the coolant required to cool nuclear fuel. Following an initial feasibility study, OPG in 2010 delved into detailed planning to refurbish the four units. Unit 2 was brought online in 1990, Unit 1 in 1992, and Units 3 and 4 in 1993. Defueling and Islanding.
