Three reactors are located at the Forsmark nuclear power plant, which is located in Östhammar Municipality. This is also the site of SFR, a final repository for low level and intermediate level radioactive waste.
The Forsmark nuclear power plant is located nearby the historic industrial estate of Forsmark in Östhammar Municipality, Uppland province. This nuclear power plant is owned by the consortium Forsmarks Kraftgrupp AB (FKA), with Vattenfall AB, a state-owned enterprise, as the main shareholder. The plant has three nuclear power reactors and its total installed net power output is 3,140 MW.
Commercial operation of the Forsmark 1 reactor began in 1980, Forsmark 2 in 1981 and Forsmark 3 in 1985. This means that Forsmark 3 is one of the two newest reactors in Sweden along with Oskarshamn 3. Forsmark 1 and 2 are basically identical boiling water reactors having a net power output of around 1,000 MW each. Forsmark 3 is also a boiling water reactor, but is a more advanced type of a somewhat larger size than the other two reactors. Forsmark 3 has a net power output of around 1,200 MW.
Forsmark is also the site of SFR, a final repository for low level and intermediate level radioactive waste, which was commissioned in 1988. SFR is owned and operated by the Swedish Nuclear Fuel and Waste Management Company, or SKB, an undertaking owned jointly by the nuclear power companies. As with the other nuclear power plants in Sweden, Forsmark has a shallow land disposal facility for low level waste.
The Forsmark nuclear power plant is permitted to operate its three reactors at the following thermal power output:
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.
