Now an in-depth investigation phase awaits to review how it will be possible to extend the operating time and how much it might cost.

– The feasibility study that was carried out shows that it is economically efficient to use investments that have already been made and that contribute to an electricity system with low carbon dioxide emissions, says Björn Linde, CEO of Forsmarks Kraftgrupp AB and Ringhals AB in a press release.
The five reactors at Forsmark and Ringhals were commissioned between 1980 and 1985.
Statliga Vattenfall is the majority owner.
