Among these tools is the “Re-Tube Tooling Platform,” a half-ton elevating work surface that is connected to four columns to allow it to move vertically across the reactor face. 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 March 2020, it was announced that the refurbishment of Unit 2 was complete, and in April 2020, the reactor achieved criticality for the first time since being reassembled. The milestone remains “a truly historic moment for Ontario,” as Ken Hartwick, OPG’s president and CEO, noted in June, as Unit 2 began producing 100% power. “I want to thank our refurbishment team, project partners, vendors and construction building trades workers for more than 24 million hours worked safely and for returning Darlington’s Unit 2 reactor to the grid at a time of unprecedented circumstances.” ■. The project was supposed to … Calder Hall was the world’s first industrial-scale nuclear power. Once built, nuclear plants generate enormous amounts of steady electricity, and hence enormous amounts of steady revenue. The tank already contained purified (demineralized) water. Unit 2’s success, which provided more lessons on how to navigate challenges, is now also driving optimism for the remainder of the project. Quick Description: Darlington Nuclear Power Plant is located along the north shore of Lake Ontario. News and information on nuclear power, nuclear energy, nuclear energy for sustainable development, uranium mining, uranium enrichment, nuclear generation … The Darlington nuclear generation station Retube and Feeder Replacement (RFR) project is important because this reliable low carbon energy source accounts for more than 60% of Ontario’s energy, with Darlington accounting for approximately 20%. The company proposed a massive C$12.8 billion project that would be implemented in phases over 112 months: Work would begin with a 40-month project to overhaul Unit 2 by February 2020; then Unit 3 by 2023; Unit 1 by 2024; and finally, Unit 4 by 2026. The province has also approved the continued operation of OPG's Pickering plant to 2024. But OPG also had three internal oversight bodies, including a dedicated committee of board directors, a construction review board, and a senior management team. The Darlington reactors have been among the best performing in OPG's CANDU fleet, including a top year in 2008 in which the plant achieved a combined 94.5% capacity factor The process required the manual loading of 6,240 new fuel bundles into the actual reactor, according to a serialized numbering sequence, OPG said. 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. BWX Technologies (BWXT) will conduct inspections and maintenance of the station’s steam generators, as well as remove fuel from each reactor core. Total generation (in 2017): 658 TWh Generation mix:hydro 393 TWh (60%); nuclear 101 TWh (15%); coal 60 TWh (9%); natural gas 58 TWh (9%); wind 29 TWh (4%); biofuels & waste 7.4 TWh; oil 7.3 TWh; solar 3.6 TWh. Every door, hallway, pipe—down to their exact bend—and overhead light has been replicated, simulating all interferences that could be encountered during actual re-tube and feeder replacement work. Because OPG is wholly owned by Ontario, every one of Unit 2’s 450 tasks were under scrutiny by an assortment of parties to ensure the refurbishment would stay on track to meet OPG’s January 2016–announced estimated total project cost of C$12.8 billion and schedule. Although the size and longer operating life of the Zion Nuclear Power Station resulted in greater activation of…, The refurbishment and restart of all four CANDU reactors at Bruce A may be Ontario’s most significant and…, The first unit of Ling Ao phase II (Unit 3) in Guangdong Province, China, entered commercial operation in…. "Darlington was supposed to cost $4 billion, (but) when it was finally finished it cost almost $15 billion," Hampton said. A nuclear unit at the Darlington plant has been shut down following a leak of heavy water on Tuesday, Ontario Power Generation said. Improper choice of equipment and a six-month labour stoppage of electrical workers also yielded some of these costs and delays. September 24, 2020 by PLANT STAFF General Energy Manufacturing BWXT Darlington isotope Laurentis manufacturing medical Mo-99 molybdenum-99 nuclear opg In 2006, at the direction of the Ontario government, Ontario Power Generation (OPG)—a corporation wholly owned by the province—began assessing the feasibility of extending the four reactors’ lifetimes, which were slated to end in the early 2020s. Pramilla Malick, of Protect Orange County, said that the CPV Valley gas-fired plant was built specifically to replace the nuclear plant. Toronto Star The last nuclear plant to be built in Ontario, Darlington Nuclear Generating Station, was planned in the 1970s. The last nuclear power plant built in Georgia, USA, was the Alvin W. Vogtle facility in Burke county, Georgia. “Our refurbishment-related overhauls and replacements mean greater reliability from both an operational and safety perspective,” said Dietmar Reiner, chief project officer. OPG has since committed to completing further DGR studies by the end of 2016.[29]. [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. A notable aspect at Darlington that bolstered the refurbishment project’s detailed planning and preparation is a distinctive training facility (Figure 1), where highly skilled workers can perform full “dress rehearsals” to practice using the more than 400 specialized tools developed by Ontario manufacturers to remove and install components, as well as conduct inspections and repairs on the project. ET) , to start a free trial, get pricing information, order a reprint, or post an article link on your website. An additional four reactors are currently under construction. [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. Darlington Nuclear Generating Station is a Canadian nuclear power station located on the north shore of Lake Ontario in Clarington, Ontario. A request for proposals (RFP) process for design and construction resulted in bids from Areva NP, Westinghouse, and Atomic Energy of Canada Limited (AECL). Finishing the refurbishment of Darlington nuclear power plant’s Unit 2 will take longer than expected. [7], After public hearings, the Canadian Nuclear Safety Commission announced in December 2015 the renewal of Darlington’s power reactor operating licence, for a 10 year period from Jan. 1, 2016 until Nov. 30, 2025, to allow for the refurbishment of the Darlington station, which began in October 2016. Watts Bar 2, which entered commercial service in 2016, was the first new reactor added since 1996. This segment involved opening the airlocks—for the first time since the plant was built in the early 1990s—and installing shielding, as well as removing interferences and installing the work platform. The project passed the half-way mark on 15 February and remains on time and on budget, OPG said. [10][11], The Darlington station incurred massive cost overruns during its construction. It is a large nuclear facility comprising four CANDU nuclear reactors with a total output of 3,512 MWe (capacity net) when all units are online. Indian Point was the only nuclear plant in New York to be excluded from the state’s clean energy standard, and Cuomo was opposed to its relicensing over perceived safety concerns. Starting in December 2017, all 480 pressure tubes were removed. The initial cost estimate for the station was $3.9 billion CAD in the late 1970s, which increased to $7.4 billion in 1981 when construction was started. Work then progressed into assembly of the unit’s 480 fuel channels. Darlington Nuclear Plant (Google Maps). Safety of Nuclear Power Reactors. [22][23][24], In August 2011, the three-member Joint Review Panel (mandated by the Ontario Ministry of the Environment and the Canadian Nuclear Safety Commission) released a report finding that the Darlington new build project would not result in any significant adverse environmental impacts (after taking into account mitigation measures). However, the company has resumed hiring of skilled trades workers to safely start this next phase on the project. Nuclear station to become first large-scale nuclear station to produce molybdenum-99. Low and intermediate level waste from Darlington is stored at the Western Waste Management Facility (WWMF) at the Bruce nuclear site near Kincardine, Ontario. Finishing the refurbishment of Darlington nuclear power plant's Unit 2 will take longer than expected. OPG’s Darlington Nuclear Generating Station is a four-unit station with a net output of 3,512 megawatts (MW). Critically, it also involved removing the unit’s 960 feeder pipes, which carry the coolant required to cool nuclear fuel. COVID, notably, posed new workforce constraints that prompted OPG to postpone the start of the Unit 3 refurbishment by three months to May 2020. In addition interest rates were running at 20 percent. The work, which was entirely automated by millwrights and boilermakers from a remote control center, benefitted from a new production planning tool the team developed that was used in other work as well. After a restart process, the refurbished unit reached first criticality in April, and it returned to full service in June. By June 2019, the team had inspected fuel bundles that were sequenced and packed by BWXT, and were readying for fuel load. News & Technology for the Global Energy Industry.

Formerly known as the Bruce Nuclear Power Development (BNPD), the facility was constructed in stages between 1970 and 1987 by the provincial Crown corporation, Ontario Hydro. After shutdown in October 2016, the process involved cooling the reactor, defueling it, installing barriers to isolate the unit, and then draining the heavy water. At its peak, the refurbishment project will require 11,800 workers per year across the industry, it said, and it has continued several programs to attract, retain, align, and develop qualified resources for the project. Not a subscriber or a registered user yet? [8], In March 2017, Ontario Power Generation (OPG) and its venture arm, Canadian Nuclear Partners, announced plans to produce Plutonium-238 as a second source for NASA. The station is the largest employer in Bruce County, with over 4000 workers. 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). “The installation process involved installing the calandria tube into a lattice site, verifying correct positioning on both reactor faces, then rolling the calandria tube, finishing with a leak test,” OPG said.

Construction was finally deemed complete in late March, 2020. The risks from western nuclear power plants, in terms of the consequences of an accident or terrorist attack, are minimal compared with other commonly accepted risks. The facility was opened in 2007, reportedly on schedule and on budget. On October 14, 2016, OPG began Canada’s largest clean infrastructure project – the refurbishment of all four of Darlington’s reactors. Ontario Power Generation won approval from the Canadian Nuclear Safety Commission last week for plans to refurbish and extend the operating life of the Darlington nuclear plant.. Defueling and Islanding. Pivotal to the project was picking the right contractors. In fact, Darlington made industrial history by becoming the first nuclear station in North America to be certified under the tough ISO 14001 environmental standard. A worker trains at Darlington’s full-scale reactor “mock-up” facility located inside of the 2014–established Darlington Energy Complex. Ontario Power Generation announced the delay at the plant… Darlington Nuclear Generating Station is a Canadian nuclear power station on the north shore of Lake Ontario in Clarington, Ontario. New Democratic Party MPP Peter Tabuns, a nuclear opponent, pointed to the province's unhappy experience with building the Darlington nuclear station. Storage strategies will differ between the two pressurized water systems (AP1000 and EPR) and the ACR-1000 due to differences in the waste characteristics. "Most of our $20-billion hydro debt in Ontario is the result of nuclear plants that were built in the 1960s, '70s and '80s, and haven't been paid for yet." The amount of tritium released to the environment was less than 1 percent of the regulatory limit and consistent with normal operational activities. The successful refurbishment of Unit 2 at the Darlington Nuclear Generating Station marked a pivotal milestone for Ontario Power Generation’s 10-year, C$12.8 billion overhaul of the plant… 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. In June 2009, the Government of Ontario put the RFP process on hold, citing unexpectedly high bids, and the uncertainty surrounding the future of the only compliant bidder (AECL). In April 1999 Ontario Hydro was split into 5 component Crown corporations with Ontario Power Generation (OPG) taking over all electrical generating stations. These storage buildings will either be a new independent building built on the site or an expansion of the existing darlington waste management facility. In April 1999 Ontario Hydro was split into 5 component Crown corporations with Ontario Power Generation (OPG) taking over all electrical generating stations. [19][20] The reactor was reconnected to the grid in June.[21]. Loading Fuel, Testing, and Restarting the Reactor. The Darlington Waste Management Facility provides dry storage for the used fuel from Darlington, after an initial period in a water-filled storage bay. [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. [14] The project was adversely affected by declining electricity demand forecasts, mounting debt of Ontario Hydro, and the Chernobyl disaster which necessitated safety reviews in mid-construction. The co-ordinates are of a viewing platform from which you can see the station. The government of the Canadian province of Ontario has announced that a CAD 12.8 billion ($9 billion) project to refurbish the four Candu units at Ontario Power Generation's (OPG) Darlington nuclear power station will start in October. [26], In November 2020 Ontario Power Generation announced plans to build a small modular reactor at Darlington Nuclear Generating Station. It is expected to be built by 2028 at the earliest.[27]. Each delay incurred interest charges on debt, which ultimately accounted for 70% of the cost overruns. The Darlington reactors have been among the best performing in OPG's CANDU fleet, including a top year in 2008 in which the plant achieved a combined 94.5% capacity factor. In 2006, OPG started the federal approvals process to build new nuclear units at the site of its Darlington Nuclear Station. In the end, the six years OPG spent on detailed planning and preparations were crucial to bringing Unit 2 back online within the planned 40 months. “But shutting down the unit is not just a matter of pulling a plug,” OPG noted. POWER Magazine readers get exclusive power industry news–every business day. Disassembling the Reactor Core. [13] The final cost was $14.4 billion CAD, almost double the initial construction budget. Data for year 2017 Built in Cumbria and costing £35m, it started operating in 1956 and was only decommissioned in 2003.The power plant had four reactors, and a total capacity of 194MW.
