Fortum, which is a partner of E.on in the OKG projet, is not in favour of the proposed closure of the nuclear units. The firm wants the reactors to be operational until the end of their scheduled life.
Fortum nuclear and thermal power executive vice-president Tiina Tuomela said: "Oskarshamn 1, which is the oldest nuclear power unit in Sweden, has applied for the environmental permit to transfer to the service mode.
"Decisions on the future of Oskarshamn 1 will not be topical in the next few years, and the unit could continue its production at the current capacity level."
