Douglas Point
The Douglas Point Nuclear Generating Station was Canada’s first full-scale nuclear power plant and the second CANDU (CANada Deuterium Uranium) pressurised heavy water reactor. Its success was a major milestone and marked Canada's entry into the global nuclear power scene. The same site was later used for the Bruce Nuclear Generating Station, which was built just to the south of Douglas Point. Douglas Point was built and owned by Atomic Energy of Canada Limited (AECL) but operated by Ontario Hydro. It was in service from 26 September 1968 to 5 May 1984. The plant served as a teaching tool for the emerging Canadian nuclear industry, and the experience gained was applied to the later CANDU power plants. Design The first CANDU was a demonstration unit, the Nuclear Power Demonstrator (NPD). In 1958, before NPD was complete, AECL formed the Nuclear Power Plant Division at Ontario Hydro’s A.W. Manby Service Centre in Toronto to manage the construction of a full-scale prototype for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kincardine, Ontario
Kincardine ( ) is a municipality located on the shores of Lake Huron in Bruce County in the province of Ontario, Canada. The current municipality was created in 1999 by the amalgamation of the Town of Kincardine, the Township of Kincardine, and the Township of Bruce. The municipality had a population of 11,389 in the Canada 2016 Census. Communities In addition to the main population centre of Kincardine itself (population 6,725), the municipality also contains the smaller communities of Armow, Baie du Dore, Bervie, Glammis, Inverhuron, Millarton, North Bruce, Tiverton, and Underwood. History In 1998, the Village of Tiverton lost its separate incorporation, and became part of the Township of Bruce. The Town of Kincardine, the Township of Kincardine, and the Township of Bruce were then amalgamated to form the Township of Kincardine-Bruce-Tiverton on January 1, 1999, with boundaries identical to those of the municipality that had existed in 1855.

Burnup
In nuclear power technology, burnup (also known as fuel utilization) is a measure of how much energy is extracted from a primary nuclear fuel source. It is measured as the fraction of fuel atoms that underwent fission in %FIMA (fissions per initial metal atom) or %FIFA (fissions per initial fissile atom) as well as, preferably, the actual energy released per mass of initial fuel in gigawatt-days/metric ton of heavy metal (GWd/tHM), or similar units. Measures of burnup Expressed as a percentage: if 5% of the initial heavy metal atoms have undergone fission, the burnup is 5%FIMA. If these 5% were the total of 235U that were in the fuel at the beginning, the burnup is 100%FIFA (as 235U is fissile and the other 95% heavy metals like 238U not). In reactor operations, this percentage is difficult to measure, so the alternative definition is preferred. This can be computed by multiplying the thermal power of the plant by the time of operation and dividing by the mass of the initial fue ...

Reactor Pressure Vessel
A reactor pressure vessel (RPV) in a nuclear power plant is the pressure vessel containing the nuclear reactor coolant, core shroud, and the reactor core. Classification of nuclear power reactors Russian Soviet era RBMK reactors have each fuel assembly enclosed in an individual 8 cm diameter pipe rather than having a pressure vessel. Whilst most power reactors do have a pressure vessel, they are generally classified by the type of coolant rather than by the configuration of the vessel used to contain the coolant. The classifications are: *Light-water reactor - Includes the pressurized water reactor and the boiling water reactor. Most nuclear power reactors are of this type. *Graphite-moderated reactor - Includes the Chernobyl reactor (RBMK), which has a highly unusual reactor configuration compared to the vast majority of nuclear power plants in Russia and around the world. *Gas cooled thermal reactor - Includes the Advanced Gas-cooled Reactor, the gas cooled fast breeder re ...

Bailey Bridge
A Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed in 1940–1941 by the British for military use during the Second World War and saw extensive use by British, Canadian and American military engineering units. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without the use of a crane. The bridges were strong enough to carry tanks. Bailey bridges continue to be used extensively in civil engineering construction projects and to provide temporary crossings for pedestrian and vehicle traffic. A Bailey bridge and its construction were prominently featured in the 1977 film '' A Bridge Too Far''. Design The success of the Bailey bridge was due to the simplicity of the fabrication and assembly of its modular components, combined with the ability to erect and deploy sections with a minimu ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tobermory, Ontario
Tobermory is a small community located at the northern tip of the Bruce Peninsula, in the traditional territory of the Saugeen Ojibway Nation. Until European colonization in the mid-19th century, the Bruce Peninsula was home to the Saugeen Ojibway nations, with their earliest ancestors reaching the area as early as 7500 years ago. It is part of the municipality of Northern Bruce Peninsula. It is northwest of Toronto. The closest city to Tobermory is Owen Sound, south of Tobermory and connected by Highway 6. Naval surveyor Henry Bayfield originally named this Port Collins Harbour. Due to similar harbour conditions it was renamed after Tobermory (; gd, Tobar Mhoire), the largest settlement in the Isle of Mull in the Scottish Inner Hebrides. The community is known as the "fresh water SCUBA diving capital of the world" because of the numerous shipwrecks that lie in the surrounding waters, especially in Fathom Five National Marine Park.

Online Refueling
In nuclear power technology, online refuelling is a technique for changing the fuel of a nuclear reactor while the reactor is critical mass, critical. This allows the reactor to continue to generate electricity during routine refuelling, and therefore improve the availability and profitability of the plant. Benefits of online refuelling Online refuelling allows a nuclear reactor to continue to generate electricity during periods of routine refuelling, and therefore improves the availability and therefore the economy of the plant. Additionally, this allows for more flexibility in reactor refuelling schedules, exchanging a small number of fuel elements at a time rather than high-intensity offline refuelling programmes. The ability to refuel a reactor while generating power has the greatest benefits where refuelling is required at high frequency, for example during the production of plutonium suitable for nuclear weapons during which low-burnup fuel is required from short irradiati ...
