Onkalo Spent Nuclear Fuel Repository
The Onkalo spent nuclear fuel repository is a deep geological repository for the final disposal of spent nuclear fuel. It is near the Olkiluoto Nuclear Power Plant in the municipality of Eurajoki, on the west coast of Finland. It is being constructed by Posiva, and is based on the KBS-3 method of nuclear waste burial developed in Sweden by Svensk Kärnbränslehantering AB (SKB). The facility is expected to be operational in 2023. History After the Finnish Nuclear Energy Act was amended in 1994 to specify that all nuclear waste produced in Finland must be disposed of in Finland, Olkiluoto was selected in 2000 as the site for a long-term underground storage facility for Finland's spent nuclear fuel. The facility, named "Onkalo" (meaning "small cave" or "cavity") is being built in the granite bedrock at the Olkiluoto site, about five kilometers from the power plants. The municipality of Eurajoki issued a building permit for the facility in August 2003 and excavation began in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Power In Finland
As of 2023, Finland has five operating nuclear reactors in two power plants, all located on the shores of the Baltic Sea. Nuclear power provided about 34% of the country's electricity generation in 2020. The first research nuclear reactor in Finland was commissioned in 1962 and the first commercial reactor started operation in 1977. The fifth reactor is in the commissioning phase, having started producing electricity and currently scheduled to begin regular operation in March 2023. Finland's nuclear reactors are among the world's most productive, with an average capacity factor of 95% in the 2010s. Operational power plants Reactors Loviisa plant Located in Loviisa, on the south coast ( Gulf of Finland), the plant comprises two VVER-440 pressurized water reactors built by Soviet Atomenergoexport, but fitted with Western instrumentation, containment structures and control systems.

Energy In Finland
Energy in Finland describes energy and electricity production, consumption and import in Finland. Energy policy of Finland describes the politics of Finland related to energy. Electricity sector in Finland is the main article of electricity in Finland. Finland lacks domestic sources of fossil energy and must import substantial amounts of petroleum, natural gas, and other energy resources, including uranium for nuclear power. Energy consumption in Finland per capita is the highest in European Union. Reasons for this include industries with high energy consumption (half of energy is consumed by industry), high standards of living, cold climate (25% of consumption is used in heating) and long distances (16% of consumption is used in transport). Finland and Estonia are two of the last countries in the world still burning peat. Overview There was no sustainable decline in CO2 emission in Finland during 1990–2007. The energy use decline 2008–2009 is based on recession and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Semantic
Semantics (from grc, σημαντικός ''sÄ“mantikós'', "significant") is the study of reference, meaning, or truth. The term can be used to refer to subfields of several distinct disciplines, including philosophy, linguistics and computer science. History In English, the study of meaning in language has been known by many names that involve the Ancient Greek word (''sema'', "sign, mark, token"). In 1690, a Greek rendering of the term ''semiotics'', the interpretation of signs and symbols, finds an early allusion in John Locke's ''An Essay Concerning Human Understanding'': The third Branch may be called [''simeiotikÃ'', "semiotics"], or the Doctrine of Signs, the most usual whereof being words, it is aptly enough termed also , Logick. In 1831, the term is suggested for the third branch of division of knowledge akin to Locke; the "signs of our knowledge". In 1857, the term ''semasiology'' (borrowed from German ''Semasiologie'') is attested in Josiah W. Gibbs' '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Into Eternity (film)
''Into Eternity'' is a 2010 Danish documentary film directed by Michael Madsen, released in 2010. It follows the construction of the Onkalo waste repository at the Olkiluoto Nuclear Power Plant on the island of Olkiluoto, Finland. Director Michael Madsen questions Onkalo's intended eternal existence, addressing an audience in the remote future. ''Into Eternity'' raises the question of the authorities' responsibility of ensuring compliance with relatively new safety criteria legislation and the principles at the core of nuclear waste management. When shown on the British More4 digital television channel on 26 April 2011, the name ''Nuclear Eternity'' was used. It received a special mention in the Sheffield Green Award at Sheffield Doc/Fest in 2010. Background ''Into Eternity'' is a documentary about a deep geological repository for nuclear waste.

Royal Institute Of Technology
The KTH Royal Institute of Technology ( sv, Kungliga Tekniska högskolan, lit=Royal Institute of Technology), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm. KTH was established in 1827 as the ''Teknologiska institutet (Institute of Technology)'' and had its roots in the ''Mekaniska skolan (School of Mechanics)'' that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the ''Mekaniska skolan'', the ''Laboratorium mechanicum'', which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Technol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentonite Clay
Bentonite () is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts (devitrification) the volcanic glass ( obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40-50 wt.%) of amorphous silica is dissolved and leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidized ) as the exposure is weathered further. As a swelling clay, bentonite has the ability to absorb large quantities of water, which increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boron Steel
Boron steel refers to steel alloyed with a small amount of boron, usually less than 1%. The addition of boron to steel greatly increases the hardenability of the resulting alloy. Description Boron is added to steel as ferroboron (~12-24% B). As the ferroboron addition lacks protective elements it is usually added after oxygen scavengers have been added. Proprietary additives also exist with oxygen/nitrogen scavengersone such contains 2% B plus Al, Ti, Si. Oxygen, carbon, and nitrogen react with boron in steel to form B2O3 (boron trioxide); Fe3(CB) ( iron boroncementite) and Fe23(CB)6 ( iron boroncarbide); and BN (boron nitride) respectively. Hardenability Soluble boron arranges in steels along grain boundaries. This inhibits the γ-α transformations (austenite to ferrite transformation) by diffusion and therefore increases the hardenability, with an optimal range of ~ 0.0003 to 0.003% B. Additionally Fe2B has been found to precipitate at grain boundaries, which may also retar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
