Nuclear power currently represents approximately 40 per cent of Sweden’s national power supply. There are three nuclear power plants in the country, with a total of seven reactors in operation. These NPPs are the Forsmark, Oskarshamn and Ringhals plants. The Forsmark NPP has three reactors in operation. The Oskarshamn NPP shut down two of its three reactors in 2017. The Ringhals NPP shut down one of its four reactors in 2019 and will shut down yet another reactor in 2020.
After 2020, there will be six nuclear reactors in operation in Sweden, distributed between the three nuclear power plants. The respective owners plan to operate these plants until circa 2040. The two reactors at the Barsebäck NPP were shut down in 1999 and 2005, respectively. These reactors are now undergoing decommissioning, together with Oskarshamn’s units 1 and 2, in addition to the Ågesta plant. Apart from the reactors in operation or undergoing decommissioning, there are a number of other nuclear installations in Sweden. They are used to manufacture nuclear fuel and store spent nuclear fuel and radioactive waste.
Licensees of nuclear facilities always bear the full responsibility for facility safety and for protecting workers and the surroundings from detriment due to ionising radiation. These safety requirements also apply during shutdown and decommissioning of a facility. The Swedish Radiation Safety Authority serves as the Government’s expert authority in the fields of nuclear power safety and radiological (radiation) protection. The role of the Swedish Radiation Safety Authority is to impose requirements to ensure nuclear safety and radiation protection, as well as to conduct follow-ups and inspections to ensure that the entities operating, shutting down or decommissioning nuclear facilities fulfil all applicable requirements and take their responsibility for radiation safety.
