Summary:

short text (1'500 characters max.)

The town Oskarshamn, which is located on the east coast of Sweden, close to Sweden's second largest island Öland, was the first place in sweden, where big commercial nuclear power plants were built up. The first two boiling water reactors (BWR), Oskarshamn 1 and 2 were build in 1972 and 1974 and are still operated until now. The biggest BWR reactor with 1450 MW of sweden is now Oskarshamn 3, which is operating since 1985 [7]. The operator OKG made a request for upgrading Oskarshamn 3 about 250MW, this was approved by Swedish Nuclear Power Inspectorate (SKI) in 2005. However Oskarshamn 3 is operating with 1450 MW only since late 2011, because of repeating turbine problems in Oskarshamn 3 [8] . Nonfunctional emergency diesel aggregates for Oskarshamn 1 since 2002 and problems with emergency diesel aggregates for Oskarshamn 2 led to temporary enforced shutdown by the swedish nuclear safety authority Strålsäkerhetsmyndigheten (SSM) in December 2012 [9]. The operator OKG made another request for upgrading Oskarshamn 2 from 605 MW to 840 MW. These plans should be implemented in 2015. OKG ask for operating both upgraded reactors 1 and 2 for each 60 years, a lot of more operating time than they initially were planned at the beginning. The NPP operator OKG, which belongs to energy companies german E.ON and the finnish Fortum, is one of the largest employers in Kalmar county.[10] . E.ON has expressed interest in replacing O1 with a new reactor, to be located on the nearby island Ävrö, which is already owned by OKG.[11] High-level spent nuclear fuel is deposited at the Clab repository in Oskarshamn.

A research working group has expressed interest in building a 4th gen research reactor (lead-cooled fast reactor, LFR) at Simpevarp. The plan would be to reprocess some of the spent fuel stored at the Clab repository and test it in a research reactor. The group consists of researchers at Chalmers University of Technology (which internationally is in a leading position in spent-fuel-reprocessing research), and former Swedish financial minister Allan Larsson (for some added political weight). OKG and Oskarshamn municipality have been positive, but SKB have been hesitant, as reprocessing nuclear waste is not part of their official program.[12]

Data:

Coordinates: 57°24′56″N 16°40′16″E

  • Operator: OKG (Oskarshamns Kärnkraftsgrupp), private corporation owned by E.ON Sverige (54.5 %) and Fortum (45.5 %)[13]
  • Capacity: total 2 603 MW. (O1: 492 MW, O2: 661 MW, O3: 1450 MW)[14]
  • (How much radiation it sets free?) Average radiation dose measured among OKG workers: 2,0 mSv.[15]
  • Dates of construction & operation:
    • O1: Start of construction 1966, start of operation 1972. Major renovations 1993-95, 1998 and 2002.[16]
    • O2: Start of construction 1969, start of operation 1974. Major renovations scheduled for 2007, 2009 and 2013/2014.[17]
    • O3: Start of construction 1980, start of operation 1985. (planned already 1976, but because of the political debate around nuclear power, the start of construction was delayed to after the referendum about nuclear power in 1980).[18]
    • OKG plans to have the plant running for at least ca 30 years more, or a 60-year life-term per reactor.
  • Proposed new reactors:
    • replacing O1 with a new reactor[19]
    • 4th gen (spent fuel) research reactor at Simpevarp.[20]
  • Electricity production: 16.8 TWh.[21] Oskarshamn NPP's production is ca 10 % of Sweden's electricity production.
  • type of reactor: BWR (Boiling Water Reactor), H2O+LEU. O1 was Sweden's first commmercial reactor. O2 has the same contruction as the two Barsebäck reactors.
  • (Sizes)
  • how much waste a reactor produces per year: Missing. Spent fuel is stored at the facility for at least 9 months, then moved to Clab for intermediate storage for 30-40 years.[22]
  • Fuel information: LEU. Mainly from Canada, but also from Russia and a number of other contractors. [23]
  • Employees: ca 930. In addition there's also ca 100 people at the facility as subcontractors.[24] During the yearly periods in the summer[25] when the fuel is changed and preventive facility maintenance is done, an additional 500-600 people may be working in the area.[26]
  • number of people living around the facility: Oskarshamn municipality 26 131 (2010)[27] (the NPP is located ca 30 km north of Oskarshamn town[28] on the east coast of Sweden, close to Sweden's second largest island Öland.)
  • number of accidents: missing. "We have had accidents such as e.g. fires, high-current-cable accidents and falls from scaffoldings, however we have not had any nuclear accidents."[29]
