Description

Bruce Nuclear Generating Station is a nuclear power station located on the eastern shore of Lake Huron in the communities of Inverhuron and Tiverton, Ontario in Canada. It occupies 932 ha (2300 acres) of land. The facility derives its name from Bruce Township, the local municipality when the plant was constructed, now Kincardine due to amalgamation.Its eight reactors are arranged into two plants (A and B) with four reactors each. Each reactor stands within a reinforced concrete containment, driving eight steam generators. The steam generators are 12 m tall, and weigh 100 tonnes each. Each plant uses three fueling machines, shared between the four reactors, which travel in a duct cut through solid rock beneath the reactors, traversing the entire plant. The duct doubles as part of the pressure relief system, connected to the vacuum building.JOURNAL,weblinkweblink" title="archive.today/20120919022859weblink">weblink yes, 19 September 2012, Nuclear Engineering and Design - Pressure relief structures of multi-unit candu nuclear power plants, 2 February 1987, 10.1016/0029-5493(87)90069-0, 100, Nuclear Engineering and Design, 21–39, Huterer, J., Brown, D.G., Osman, M.A., Ha, E.C., Each reactor has its own turbine generator set, with one high-pressure turbine and three low-pressure turbines driving one generator.WEB, Reporter's Guide to Bruce Power (Revision 4),weblink 24 March 2011, Aug 2007, yes,weblink" title="web.archive.org/web/20100401055949weblink">weblink 1 April 2010, dmy-all, {{webarchive |url=https://web.archive.org/web/20101124084433weblink |date=24 November 2010}} The turbine hall is about 400 m long at each plant and houses the four turbine generator sets.

Each reactor requires 6240 fuel bundles that weigh 22.5 kg each, or about 140 tonnes of fuel. There are 480 fuel channels per reactor, containing 12 bundles each. There is storage capacity for about 23,000 bundles.

Comparison with Pickering

Compared to the other major Canadian nuclear power plant built earlier, Pickering station, the Bruce reactors have higher power output, achieved by: increasing the number of fuel channels, increasing the number of bundles per channel, and a change in the fuel bundle itself.At Bruce, the fuelling equipment is shared by the four reactors of each plant, while at Pickering each reactor had a fuelling machine. The Bruce fuelling machine and fuel channel end fitting design (mostly by Canadian General Electric) is based on the Nuclear Power Demonstration design. The Pickering design by AECL was based on Douglas Point.WEB,weblink CANDU ORIGINS AND EVOLUTION - PART 1 OF 5 AN OVERVIEW OF THE EARLY CANDU PROGRAM PREPARED FROM INFORMATION PROVIDED BY JOHN S. FOSTER, Canteach, February 2001, 27 July 2014, Foster John S., Brooks G.L., yes,weblink 11 August 2014, no, The building design of the reactor differs: Bruce uses a squarish "close-in" design, in which as much of the equipment as possible is arranged outside the main containment envelope for easier access during maintenance and emergencies. The steam generators penetrate the containment. The primary coolant pumps and primary piping systems are inside the containment enclosure, but the pump motors are outside containment and the drive shaft seals form the containment boundary.WEB,weblink Chernobyl - A Canadian Technical Perspective, Canteach / AECL, 27 July 2014, Howieson J.Q., Snell V.G., yes,weblink 11 August 2014, no, Pickering has round domes which enclose much of the secondary cooling equipment.WEB, Simmons, R.B.V., Nuclear Power Symposium Lecture No. 10: Plant Layout,weblink Atomic Energy Of Canada Limited (AECL), 20 August 2017,weblink 20 August 2017, no,
  • The Pickering A system did not originally have a second independent shutdown system. The Bruce containment concept differs: the reactor's reactivity mechanism deck serves as a part of the containment boundary, is closer to the reactor, and more prone to damage in the event of an accident ("accidental physical disassembly"). The designers therefore foresaw the need for a second safety system to reduce the risk on an accident. Bruce received a second, fully independent Safety Shutdown System (SDS2) which uses a liquid neutron poison injection method.WEB,weblink CANDU ORIGINS AND EVOLUTION PART 5 OF 5 THE ORIGINS & EVOLUTION OF THE SECOND SHUTDOWN SYSTEM, CANTEACH, February 2001, 27 July 2014, Brooks G.L.,weblink 11 August 2014, no,
  • The Bruce system also has a high-pressure Emergency Coolant Injection System (ECIS).
  • Each Bruce "4 pack" has its own Vacuum Building, while Pickering has one per eight reactors.
  • At Pickering, the vacuum duct was closed by nonreturn valves, to prevent flow of the steam/air mixture from the duct to a non-accident reactor unit following a LOCA. In the Bruce concept, there is no such non-return valve; the reactor buildings are all interconnected during normal operation.
  • Bruce uses single-circuit heat transport system, while Pickering had two circuits.
  • The first two reactor units of Pickering A originally used Zircaloy-2 pressure tubes. All subsequent CANDU units use a zirconium - 2.5% niobium alloy.
  • Bruce uses a pressurizer to maintain coolant pressure, Pickering a different system.{{vague|date=August 2017}}
  • The Pickering design utilized 12 small steam generators operated in groups of three which can be individually valved out of the heat transport loop, as can the 16 pumps per reactor, with 4 being spare. At Bruce, the number of steam generators and coolant pumps was reduced to 8 and 4 respectively, without any spare pumps, thereby simplifying the piping. The Bruce system permits reactor power level to be adjusted more quickly and easily.BOOK, Atomic Energy of Canada Limited, Canada enters the nuclear age, 1997, 978-0-7735-1601-4,

Construction costs

Bruce A was projected to cost {{currency|0.9|CAD}} billion (1969), and actually cost $1.8 billion (1978), a 100% over-run. Bruce B was projected to cost $3.9 billion (1976), and actually cost $6 billion (1989) in "dollars of the year", a 50% over-run.WEB, Better Never Than Late,weblink Greenpeace, 4 April 2011, October 2008,weblink" title="web.archive.org/web/20150924041042weblink">weblink 24 September 2015, yes, dmy-all, WEB,weblink Appendix 2 Ontarioís Nuclear Generating Facilities: A History and Estimate of Unit Lifetimes and Refurbishment Costs, pembinafoundation.org, 2018-06-26,weblink 4 April 2017, yes, These figures are better than for Pickering B or Darlington (at 350%, not accounting for inflation).

The average price per MWh that will be paid to Bruce Power for all electricity generated from 2016–2064 (covering the entire refurbishment period for Units 3–6 plus the entire expected remaining post-refurbishment lifetimes of all eight Bruce Power reactors (including the two that were already refurbished)) was estimated to be approximately {{CA$|80.6}}/MWh in 2017 dollars by the Financial Accountability Office of Ontario. In contrast, the estimated average price of nuclear electricity from all three Ontario nuclear plants during that same 2016–2064 period was estimated to be {{CA$|80.7}}/MWh in 2017 dollars, the 2017–2018 unit cost of Ontario nuclear power was {{CA$|69}}/MWh, and the current price of electricity for "most residential and small business customers" was {{CA$|114.9}}/MWh (prior to the Fair Hydro Plan) or {{CA$|97.6}} (after the Fair Hydro Plan).

Blackout of 2003

During the Northeast Blackout of 2003 three Bruce B units continued running at 60% reactor power and 0% grid electrical power. They were able to do so for hours, because they had steam bypass systems designed to de-couple the reactor output from the generator electrical output. The three units were reconnected to the grid within 5 hours. Bruce A and B stations were designed to operate indefinitely while disconnected from the grid.JOURNAL, Carvalho, V.F., Acchione, P.N., Performance of Nuclear Unit Controls in Grid Emergency Situations, IFAC Proceedings Volumes, December 1986, 19, 16, 161–168, 10.1016/S1474-6670(17)59375-1, "Contrary to popular belief, the electrical generators of nuclear plants can follow the load demands of the electrical grid provided specific engineered systems to permit this mode of operation are included in the plant design."WEB, Ontario Electrical Grid and Project Requirements for Nuclear Plants,weblink Ontario Society of Professional Engineers (OSPE), 4 April 2011, 8 March 2011, {{dead link|date=September 2017 |bot=InternetArchiveBot |fix-attempted=yes }}

Cobalt-60 production

Cobalt-60 (60Co) can be produced in a CANDU reactor by using adjuster rods made primarily out of 59Co (instead of the normal stainless steel), which is slowly transmuted into 60Co via neutron activation (59Co + n → 60Co).WEB, Canadian Nuclear Worker,weblink Canadian Nuclear Workers Council, 9 August 2017, 3, June 2017, The following day, Bruce Power announced the completion of a Cobalt-60 harvest during the Unit 5 outage. Following the harvest, new rods of Cobalt-59 (becomes Cobalt-60 after up to two years in the reactor) were inserted in Unit five along with four rods of medical High Specific Activity Cobalt which is used to treat brain cancer.,weblink" title="web.archive.org/web/20170809212717weblink">weblink 9 August 2017, no, WEB, The Canadian Nuclear Factbook 2017,weblink Canadian Nuclear Association, 9 August 2017,weblink 9 August 2017, no, These now-intensely-radioactive cobalt-60 adjuster rods are then "harvested" (removed and replaced with fresh 59Co adjuster rods) after one to three years of use in the reactor during a routine reactor shutdown, and are later processed into sealed 60Co sources of varying intensities by Nordion.NEWS, Gowan, Rob, Bruce Power to produce Cobalt-60,weblink 9 August 2017, Owen Sound Sun Times, Owen Sound Sun Times, 17 November 2014, en-CA,weblink" title="web.archive.org/web/20170809211831weblink">weblink 9 August 2017, yes, dmy-all, WEB, The Role of Nuclear: Present and Future,weblink 9 August 2017, 3–4,weblink 24 May 2017, no, WEB, Bruce Power: Canada's Largest Public-Private Partnership,weblink 9 August 2017, 22, August 2015, Unrelated to refurbishment, yet extremely innovative work that takes during planned maintenance outages, is the Cobalt-60 harvest. Working together, Bruce Power and Nordion provide a reliable, long-term, end-to-end Cobalt-60 supply, which fuels gamma processing operations such as irradiation facilities that sterilize single-use medical devices. Cobalt is mined like any other mineral. It's removed from the ground and processed into pure Cobalt-59 powder. Once processed into powder, it's compressed into slugs, which are coated with nickel. These slugs are then encapsulated and assembled into adjuster rods, which are used to control the reaction in Bruce Power's reactors, where the cobalt is activated by absorbing neutrons to become Cobalt-60. The rods are in the reactor for a minimum of one year and maximum of 2.5 years. Bruce Power harvests the rods during planned maintenance outages on the units. The bundles are then received by Nordion and the Cobalt-60 is removed from its encapsulation and welded into a new double-encapsulated source called C-188. It is then shipped to the sites of Nordion's customers for use in irradiators. In 2014, Bruce Power and Nordion signed an agreement for up to an additional 14 years to provide a long-term supply of Cobalt-60 that will support health care around the world. Cobalt-60 makes an invaluable contribution to the health care industry and is used to sterilize approximately 40 per cent of all single-use medical devices and equipment produced globally.,weblink" title="web.archive.org/web/20170809211246weblink">weblink 9 August 2017, no, The Bruce nuclear power plant has been producing 60Co since the 1980s, and almost all of the world's supply of 60Co comes from various CANDU nuclear reactors, with Bruce being the single largest supplier.WEB, Nordion and Bruce Power ensure global Cobalt-60 supply up to 2064,weblink 9 August 2017, 8 November 2016,weblink" title="web.archive.org/web/20170809212224weblink">weblink 9 August 2017, no, WEB, Nuclear Power in Canada - World Nuclear Association,weblink www.world-nuclear.org, World Nuclear Association, 9 August 2017, As well as their use for electricity, Candu power reactors produce almost all the world's supply of the cobalt-60 radioisotope for medical and sterilization use.,weblink" title="web.archive.org/web/20170809212329weblink">weblink 9 August 2017, no, NEWS, Vulcan, Tom, Radioisotopes: A Market In Decay? {{!, ETF.com|url=http://www.etf.com/sections/features-and-news/2095-radioisotopes-a-market-in-decay?nopaging=1|accessdate=9 August 2017|work=www.etf.com|date=19 April 2010|language=en|archive-url=https://web.archive.org/web/20170809213648weblink|archive-date=9 August 2017|dead-url=no}}NEWS, Canadian companies collaborate to secure isotope supplies,weblink 9 August 2017, www.world-nuclear-news.org, World Nuclear News, 8 November 2016,weblink" title="web.archive.org/web/20170809213514weblink">weblink 9 August 2017, no, WEB, Clean Nuclear Power {{!, Safe Hospitals|url=http://www.cleannuclearpowersafehospitals.com/|website=www.cleannuclearpowersafehospitals.com|accessdate=9 August 2017|archive-url=https://web.archive.org/web/20170725030308weblink|archive-date=25 July 2017|dead-url=no}} {{As of|2007}}, Bruce supplied over 40% of the world's 60Co.

(File:NPP Bruce A.jpg|thumb|Bruce A looking Southwest across Baie Du Dor)There are more than 56 kilometres of roads on site, and at least 25 major structures. The site has its own fire department, laundry and medical centre.

Douglas Point, 1960–1984

Encompassed by the Bruce site is the shut-down Douglas Point reactor, an earlier version of the CANDU design. Construction began in 1960; was operational in 1967; and was shut down in 1984. The present Bruce reactors each are roughly 4 times the capacity of the 200 MW Douglas Point unit.

Bruce Heavy Water Plant, 1973–1997

The Bruce Heavy Water Plant (BHWP) also occupied the site. Atomic Energy of Canada Limited contracted the Lummus Company of Canada Limited in 1969 to design and construct the first phase of the plant, while Ontario Hydro was responsible for commissioning and operating.BOOK, Abstract for "Separation of Hydrogen Isotopes", 68, 27–39, American Chemical Society, 10.1021/bk-1978-0068.ch002, Bruce Heavy Water Plant Performance, ACS Symposium Series, 1978, Davidson, G. D., 978-0-8412-0420-1, It was planned to consist of four sub-plants, A through D:
  • A was in production in 1973, shutdown in 1984, and demolished in 1993;
  • B was in production in 1979, partially shutdown in 1993, completely closed in 1997, and subsequently demolished;
  • C was cancelled, and never built;
  • D was 70% completed when cancelled, and subsequently demolished in 1995.
During its lifetime, BHWP produced 16,000 tonnes of reactor grade heavy water. Capacity of each sub-plant was planned to be 800 tonnes/annum. The plant size was approximately 960 m by 750 m. The heavy water was 99.75% pure.The production of a single pound of heavy water required 340,000 pounds of feed water.WEB, Heavy Water Production,weblink Federation of American Scientists, 27 March 2011,weblink" title="web.archive.org/web/20110405024941weblink">weblink 5 April 2011, no,

Bruce Bulk Steam System, 1972–2006

Steam from Bruce A could be diverted to the Bruce Bulk Steam System (BBSS) to provide energy for the production of heavy water (750 MW thermal), to heat buildings within the development (15 MW th), or to provide energy (72 MW th) for the adjacent Bruce Energy Centre (BEC). The BEC supported industries such as greenhouses and plastic manufacturers. As one of the largest bulk steam systems in the world, this system could produce 5,350 MW of medium-pressure process steam, and had over 6 km of piping.WEB, Small and Medium Reactors: Development Status and Application Aspects,weblink IAEA, 27 March 2011, Jürgen Kupitz, March–April 2000, 38,weblink" title="web.archive.org/web/20150602133110weblink">weblink 2 June 2015, no, {{rp|15–16}} It was demolished by the end of 2006.

Inverhuron Provincial Park, 1950–present

OPG owns the nearby 288 ha Inverhuron Provincial Park on Lake Huron, bordering Inverhuron, 14 km north-east of Kincardine, which is not part of the Bruce site proper, and leases it to the Ontario Ministry of Natural Resources. As a condition of the operating licence for Bruce Nuclear, OPG retained a 914 m radius exclusion zone in the northwest corner of the park. after operating over 25 years the park campground was phased out in 1976, because of safety concerns related to the heavy water production. When heavy water was no longer produced, the park campground was allowed to re-open in 2000 on the same spot.WEB, Inverhuron Draft Vegetation Management Plan,weblink Queen's Printer for Ontario, Ontario Ministry Natural Resources (OMNR), 4 April 2011, 2007, 42,weblink" title="web.archive.org/web/20120925231736weblink">weblink 25 September 2012, no, {{rp|7}}

Eagles

The heated water released back into Lake Huron by the plant prevents the surrounding shoreline from freezing over during winter and attracts an inordinate concentration of lake fish, which in turn attracts droves of bald eagles wintering in the area. Numbers peak around late February to early March and it is not uncommon for visitors to observe several dozen eagles in and around the general vicinity of the plant at any given time during these months.JENNIFER SCHLEICH Nuclear plant calls in hawks to scare off nesting gulls {{Webarchive|url=https://web.archive.org/web/20130801020233weblink |date=1 August 2013 }} The Whig, April 6, 2011Rob Gowan Eagles create stir {{Webarchive|url=https://web.archive.org/web/20130118063117weblink |date=18 January 2013 }}, Owen Sound Sun Times, 13 January 2013
