POSIVA
Posiva Oy is a Finnish company with headquarters in the municipality of Eurajoki, Finland. It was founded in 1995 by Teollisuuden Voima (60% of stock) and Fortum (40% of stock), two Finnish nuclear plant operators, for researching and creating a method of final disposal of spent nuclear fuel from their plants. For this purpose, Posiva is currently constructing the Onkalo spent nuclear fuel repository, the world's first deep geological repository A deep geological repository is a way of storing hazardous or radioactive waste within a stable geologic environment (typically 200–1000 m deep). It entails a combination of waste form, waste package, engineered seals and geology that is suite ..., at the Olkiluoto Nuclear Power Plant site.

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] |
High-level Radioactive Waste Management
High-level radioactive waste management concerns how radioactive materials created during production of nuclear power and nuclear weapons are dealt with. Radioactive waste contains a mixture of short-lived and long-lived nuclides, as well as non-radioactive nuclides. There was reportedly some of high-level nuclear waste stored in the United States in 2002. The most troublesome transuranic elements in spent fuel are neptunium-237 (half-life two million years) and plutonium-239 (half-life 24,000 years). Consequently, high-level radioactive waste requires sophisticated treatment and management to successfully isolate it from the biosphere. This usually necessitates treatment, followed by a long-term management strategy involving permanent storage, disposal or transformation of the waste into a non-toxic form. Radioactive decay follows the half-life rule, which means that the rate of decay is inversely proportional to the duration of decay. In other words, the radiation from a lo ...

Deep Geological Repository
A deep geological repository is a way of storing hazardous or radioactive waste within a stable geologic environment (typically 200–1000 m deep). It entails a combination of waste form, waste package, engineered seals and geology that is suited to provide a high level of long-term isolation and containment without future maintenance. This will prevent any radioactive dangers. A number of mercury, cyanide and arsenic waste repositories are operating worldwide including Canada (Giant Mine) and Germany (potash mines in Herfa-Neurode and Zielitz) and a number of radioactive waste storages are under construction with the Onkalo in Finland being the most advanced. Principles and background Highly toxic waste that cannot be further recycled must be stored in isolation to avoid contamination of air, ground and underground water. Deep geological repository is a type of long-term storage that isolates waste in geological structures that are expected to be stable for millions of years, ...

Olkiluoto Nuclear Power Plant
The Olkiluoto Nuclear Power Plant ( fi, Olkiluodon ydinvoimalaitos, sv, Olkiluoto kärnkraftverk) is one of Finland's two nuclear power plants, the other being the two-unit VVER Loviisa Nuclear Power Plant. The plant is owned and operated by Teollisuuden Voima Oyj (TVO), a subsidiary of Pohjolan Voima, and is located on Olkiluoto Island, on the shore of the Gulf of Bothnia, in the municipality of Eurajoki in western Finland, about 20 kilometres from the town of Rauma and about 50 kilometres from the city of Pori. The Olkiluoto plant consists of two boiling water reactors (BWRs), each producing 890 MW of electricity, together comprising 22% of the country's electricity generation for 2020. A third reactor, Unit 3, reached first criticality in late 2021, and at a nameplate capacity of 1,600 MW net electric output, will by itself satisfy 14% of the country's electricity demand. Unit 3 is an EPR reactor and has been under construction since 2005. The start of commercial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helsingin Sanomat
''Helsingin Sanomat'', abbreviated ''HS'' and colloquially known as , is the largest subscription newspaper in Finland and the Nordic countries, owned by Sanoma. Except after certain holidays, it is published daily. Its name derives from that of the Finnish capital, Helsinki, where it is published. It is considered a newspaper of record for Finland. History and profile The paper was founded in 1889 as ''Päivälehti'', when Finland was a Grand Duchy under the Tsar of Russia. Political censorship by the Russian authorities, prompted by the paper's strong advocacy of greater Finnish freedoms and even outright independence, forced Päivälehti to often temporarily suspend publication, and finally to close permanently in 1904. Its proprietors re-opened the paper under its current name in 1905. Founded as the organ of the Young Finnish Party, the paper has been politically independent and non-aligned since 1932. During the Cold War period ''Helsingin Sanomat'' was among the Finn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
