Forsmark

Three reactors are located at the Forsmark nuclear power plant, which is located in Östhammar Municipality. Forsmark is not only the site of SFR, a final repository for low level and intermediate level radioactive waste, this is also where the Swedish Nuclear Fuel and Waste Management Company, or SKB, seeks to construct a repository for spent nuclear fuel.

The Forsmark nuclear power plant is located near the town of Forsmark in Uppland County. The NPP is owned by Forsmarks Kraftgrupp AB (FKA), with state-owned Vattenfall AB as the main shareholder; Mellansvensk Kraftgrupp AB owns around one-fourth of the shares, and E.ON approximately one-tenth.

Forsmark’s reactors

Forsmark’s total installed net power output is 3,140 megawatts (MW). The nuclear power plant has three reactors:

Forsmark 1

  • Commissioned in 1980
  • Boiling water reactors

Forsmark 2

  • Commissioned in 1981
  • Boiling water reactors

Forsmark 3

  • Commissioned in 1985
  • Boiling water reactor

The Forsmark nuclear power plant is presently licensed to operate its three reactors at the following thermal power output:

Forsmark 1 2,928 MW
Forsmark 2 3,253 MW (test operation)
Forsmark 3   3,300 MW

The thermal power output is the heat output developed inside a reactor.
MW = megawatt (1,000 kilowatts)
1 megawatt hour (MWh) = 1,000 kilowatt hours (kWh)

Example: A reactor’s thermal output of 2,000 MW is transformed in the turbine generator to an electrical power output of around 700 MW. After one hour of operation, 700 megawatt hours (MWh) of electricity energy have been produced.

Repository for low level and intermediate level waste

Forsmark is also the location of SFR since 1988, a final repository for low level and intermediate level radioactive waste. SFR is owned and operated by the Swedish Nuclear Fuel and Waste Management Company (SKB), an undertaking owned jointly by the nuclear power companies. As at the other nuclear power plants in Sweden, Forsmark has a shallow land disposal facility for low level waste.

Repository for low level and radioactive waste

Repository for spent nuclear fuel

The company SKB seeks permission to construct a geological repository for spent nuclear fuel at Forsmark. The application is being examined by the Swedish Radiation Safety Authority. The Swedish Government will ultimately decide whether or not a repository will be allowed to be constructed.
