STOCKHOLM--The Oskarshamn 2 nuclear reactor in southern Sweden will be taken offline Thursday after the Swedish Radiation Safety Authority ordered an immediate shut-down due to safety concerns.
The authority said the reactor's operator, OKG, which is owned by German utility E.ON AG and Finnish Fortum Oyj, hasn't been able to show that important safety functions comply with the required standards.
The authority's concerns relate mainly to diesel generators which are part of the plant's backup power system.
