Äspö Hard Rock Laboratory
Äspö Hard Rock Laboratory (''Äspölaboratoriet'') is a research site located outside Oskarshamn in Kalmar County, Sweden. The laboratory is located in the Misterhult, Misterhult archipelago, near the Oskarshamn Nuclear Power Plant (''Oskarshamns Kärnkraftverk''). General information The Äspö Hard Rock Laboratory is a research facility for future geological disposal of spent nuclear fuel. The plant is owned and operated by Svensk Nuclear Fuel Management AB (''Svensk Kärnbränslehantering AB''). It was built to test different methods and possibilities for final disposal of spent nuclear fuel. At the laboratory a series of experiments are performed at depths of into the bedrock. The laboratory is used by both Swedish and international experts. Much of the research is done for the construction of the future Spent Fuel Repository. There is no spent nuclear fuel on the site which makes it possible to keep the Äspö laboratory open to the public. There is an exhibition at the ...

Research
Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oskarshamn
Oskarshamn is a coastal city and the seat of Oskarshamn Municipality, Kalmar County, Sweden with 17,258 inhabitants in 2010. History Etymology Döderhultsvik was the original name before a town charter was granted in 1856. The name was then changed to Oscarshamn (meaning: Oscar's port) after the king Oscar I of Sweden. The spelling has later changed to Oskarshamn. Struggle for town charter The location of Oskarshamn was known as Döderhultsvik since the Medieval age. In 1645, the city of Kalmar, to the south, made a request to the Royal Government on holding commerce in the bay there, which was granted, giving it merchancy rights as a ''köping''. There followed 200 years of merchancies in the town, during which it was governed and dependent on Kalmar; while the surrounding towns and municipalities made frequent requests to grant it a charter, consequently turned down each of the attempts made in the years: 1786, 1798, 1800, 1815, 1818, 1823, 1825, 1830 and 1838. In 1843 it got s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oskarshamn Nuclear Power Plant
The Oskarshamn Nuclear Power Plant is one of three active nuclear power stations in Sweden. The plant is about north of Oskarshamn, directly at the Kalmarsund at the Baltic Sea coast and with one active reactor, producing about 10% of the electricity needs of Sweden. All reactors were built using BWR technology. Unit 1 had an installed output of 494 MW and Unit 2 664 MW; these are now decommissioned. Unit 3, the newest reactor block at the facility, has an installed output of 1,450 MW. Clab, the temporary storage facility for spent nuclear fuel from all Swedish reactors, is also located at the site. Operator The responsible utility is OKG, short for the ''Oskarshamnsverkets Kraftgrupp AB'', which was acquired by Sydkraft in 1993, (later: '' E.ON Sverige''). Uniper owns 54.5% and the other partner Fortum 45.5% of OKG. History On 23 September 2003, Unit 3 of the reactor was shut down due to mechanical problems, and together with a failure that occurred in a ...

Geological
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their Geochronology, absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedrock
In geology, bedrock is solid rock that lies under loose material ( regolith) within the crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave it susceptible to erosion. Bedrock may also experience subsur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power In Sweden
The electricity sector in Sweden has three operational nuclear power plants with 6 operational nuclear reactors, which produce about 30% of the country's electricity. The nation's largest power station, Forsmark Nuclear Power Plant, has three reactors producing 3.3 GW and 14% of Sweden's electricity. Sweden formerly had a nuclear phase-out policy, aiming to end nuclear power generation in Sweden by 2010. On 5 February 2009, the Government of Sweden announced an agreement allowing for the replacement of existing reactors, effectively ending the phase-out policy. In June 2023, the new Kristersson Cabinet established after the country's 2022 Swedish general election, 2022 election voted to switch the national energy target from 100% renewable electricity by 2045 to 100% fossil fuel-free electricity by 2045, a move seen as supporting and extending the ongoing use of nuclear power in the country. At the time, hydro, nuclear, and wind power already produced 98% of Sweden's electricity, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioactive Waste Repositories
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered ''radioactive''. Three of the most common types of decay are alpha, beta, and gamma decay. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and nuclear forces. Radioactive decay is a random process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as a half-life. The half-lives of radioactive atoms have a huge range: from nearly instantaneous to far longer than the age of the universe. The decaying nucleus is called the parent ra ...
