Ringhals 3
Varberg, Hallands län
Current power1,065 MW
Reactor typePressurized water reactor
A pressurized water reactor (PWR) uses pressurized water as a coolant to prevent boiling. This water transfers heat to a secondary circuit that drives the turbines, ensuring that radioactive water never reaches the turbines.

Oskarshamn 3
Oskarshamn, Kalmar län
Current power1,417 MW
Reactor typeBoiling water reactor
A boiling water reactor (BWR) allows water to boil directly in the reactor, creating steam that drives the turbines. This is a simpler design but requires the turbines to handle radioactive steam.
