The Oskarshamn Nuclear Power Plant is one of three active nuclear power stations in Sweden. The plant is about 30 kilometers north of Oskarshamn directly at the Kalmarsund at the Baltic Sea coast and with three reactors produces about 10% of the electricity needs for Sweden. All reactors use BWR technology.

Oskarshamn Nuclear Power Plant Unit 1 has an installed output of 487 MW, Unit 2 627 MW, and Unit 3, the newest reactor block at the facility, has an installed output of 1,194 MW. The nuclear power station Oskarshamn is thereby one of the largest power stations in the Nordic area by production.

Clab, the temporary storage facility for spent nuclear fuel from all Swedish reactors, is also located at the site.

The responsible utility is OKG, short for the Oskarshamnsverkets Kraftgrupp OKG, which was acquired by Sydkraft in 1993, which is called E.ON Sverige currently. E.ON Sverige owns 54.5% and the other partner Fortum 45.5% of OKG.

Ringhals Nuclear Power Plant is a Swedish nuclear power plant with 4 reactors, three pressurized water reactors and one boiling water reactor. Ringhals Nuclear Power Plant is situated on the Värö Peninsula (Swedish: Väröhalvön) in Varberg Municipality approximately 60 km south of Gothenburg. With a total power rating of 3560 MWe, it is the largest power plant in Sweden and generates 24 TWh of electricity a year, the equivalent of 20% of the electrical power usage of Sweden. It is owned 70% by Vattenfall and 30% by E.ON.

Following a number of security breaches and incidents since 2005, the Swedish Radiation Safety Authority decided to put Ringhals under increased surveillance.
