Plans for a second nuclear power plant in Oskarshamn began as early as 1967. In 1969 an order was once again placed to Asea. O2 was connected to the power grid from the first time in October 1974. The plant officially started operation in December that same year. O2 is constructed in the same way as both of the reactors at Barsebäck. A power upgrade at O2 was completed in 1982, from 580 MW to 630 MW.
O2 is faced with an extensive modernisation during the next ten years. The generator and transformer will be replaced first. The most important stages of the modernisation will occur during 2007, 2009 and 2012 and will involve, among other things, replacing the low pressure turbine and the renovating the control room. A new reactor protection system and new control equipment for the turbine facilities will also be completed. In connection with the modernisation of O2, the education and training of personnel in the control room will be moved from Studsvik to a new simulator located on Simpevarp peninsula.
