Status at Swedish nuclear power plants

Press release

The Swedish Nuclear Power Inspectorate (Statens Kärnkraftsinsepktionen, SKI) communicated on 14 September on the corrective measures that are required in order to restart units 1 and 2 at the Forsmark nuclear power plant. Forsmark stated that it will analyse the situation and then give an estimate of a restart time. Currently tests are being carried out to clarify this. Forsmark's unit 3 is operating normally. Unit 2 at the Oskarshamn nuclear power plant has received permission from SKI to be restarted after its annual revision, which today was announced to end on 23 September. The unit will start by testing a new generator during which it will operate at approximately 30 percent output. Unit 1 is expected to restart around the turn of the year after changes in its back-up power system have been concluded. Oskarshamn's unit 3 is operating normally. The unplanned shutdowns have so far caused a production loss of approximately 0.7 TWh to Fortum. However, this loss has been fully compensated by thermal output, the total capacity of which is some 1,500 MW. Units 1 and 2 at Forsmark were shut down on 25 July due to a fault discovered in the power plant's back-up power system. Following the incident, also Oskarshamn's unit 1, which has a similar back-up power supply system, was shut down. Units 2 in both Forsmark and Oskarshamn have been closed for planned annual revisions during part of the shutdown period, during which inspections and improvements have been made.
