The Nuclear power station Oskarshamn is one of three active nuclear power stations in Sweden. The plant is about 30 kilometers (19 mi) 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.
11-479: 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. The responsible utility is OKG , short for the Oskarshamnsverkets Kraftgrupp AB , which
22-545: Is a stub . You can help Misplaced Pages by expanding it . Swedish Nuclear Fuel and Waste Management Company The Swedish Nuclear Fuel and Waste Management Company ( Svensk Kärnbränslehantering Aktiebolag , abbreviated SKB ) is a company founded by the Swedish nuclear power industry. Among its primary operations are the management and disposal of nuclear waste and expended nuclear fuel . Its main offices are in Stockholm , but
33-470: Is now owned by Svensk Kärnbränslehantering Aktiebolag (SKB). It was opened in 1985 for the storage of spent nuclear fuel from all Swedish nuclear power plants . The fuel is stored for 30 to 40 years, in preparation for final storage. The facility currently contains approximately 7,300 tons of high-level waste , submerged in 8 meters of water, in pools 30 meters below the surface. Contaminated reactor components, such as control rods , are also stored at
44-451: The TT news agency that a welder on his way in to the plant on Wednesday morning was caught with a relatively small amount of a highly explosive substance. The substance was later shown to be from nail polish and the event had no relevance to the operation of the plant or nuclear safety. During 2010 Unit 2 underwent power and security upgrades. Unit 3 was after many upgrades the most powerful BWR in
55-638: The coolant for all 3 reactors, capable of making 12 kg per day. With the closure of reactor 1 and 2, surplus capacity is available, and an agreement to supply so-called pink hydrogen to gas company Linde was made in January 2022. Clab The Clab , also known as Centralt mellanlager för använt kärnbränsle ( Swedish for 'Central holding storage for spent nuclear fuel') is an interim radioactive waste repository located at Oskarshamn Nuclear Power Plant about 25 km north of Oskarshamn . Clab used to be owned by Oskarshamnsverkets Kraftgrupp AB (OKG) but
66-566: The facility. Waste produced from Sweden's nuclear power plants will continue be stored at the facility until the Swedish Nuclear Fuel and Waste Management Company can complete construction of a more permanent storage site at Forsmark . The facility contains an in-pool station where passive gamma-measurements can be done on spent nuclear fuel. 57°24′43″N 16°39′18″E / 57.412°N 16.655°E / 57.412; 16.655 This radioactivity –related article
77-440: The grindgear sections at the plant. Modifications were later made to all the plants to address the issue. On May 21, 2008, a welder tested positive for trace elements of explosives on a carrier bag and his hand at the entrance security check. The same evening Reactor 1 of the facility was shut down to allow bomb teams to sweep the facility. With police investigations ongoing, Kalmar police spokesperson Sven-Erik Karlsson confirmed to
88-415: The world at approximately 1450 MW e . Due to the upgrade, the reactor had been on and off the grid with prolonged maintenance outages throughout 2010. Unit 2 was upgraded in several steps and was planned to a reach maximum capacity of thermal power 2,300 MW and 840 MW e , but was closed before all upgrades had been performed. On September 30, 2013, a portion of the plant (the third reactor)
99-457: Was acquired by Sydkraft in 1993, (later: E.ON Sverige ). Uniper owns 54.5% and the other partner Fortum 45.5% of OKG. On July 25, 2006, Units 1 and 2 were shut down as a precaution after a safety-related incident at a similar reactor at the Forsmark plant . The incident related to a failure of diesel generators to automatically start up when required, after a blackout caused by a shortcut at
110-419: Was closed when a group of jellyfish clogged the cooling water intake pipes. It was not indicated as to whether the event had been classified as a safety disturbance yet, and to what level on the scale used for nuclear plants. A decision on premature shutdown of units 1 and 2 was made in 2015. The decision entailed that there would be no future investments at unit 2 and the reactor would not be restarted. Unit 1
121-489: Was originally set for decommissioning on June 29, 2017, but it was closed prematurely due to an "operational disturbance" on June 17, 2017. It was decided not to restart the unit ahead of the shutdown scheduled for June 29, 2017. In December 2018 a strategy was outlined for the "radiological demolition" of units 1 and 2 to be carried out between 2020 and 2028. This will allow the land to be used for other nuclear power related purposes. The site has its own hydrogen production as
