Turbine
- In-depth data about the turbine units. One unit per block. One turbine unit is connected to the reactor. The turbine unit consists of one high-pressure turbine and three low-pressure turbines that are mounted on the same shaft as the generator.
- The turbine buildings also contain the condenser, cooling water and feedwater pumps.

Electrical equipment
- Key facts about the electricity generator, transformer and reserve-power diesels.
- An electricity generator is linked to each turbine at Barsebäck.
- With two turbines – one on each block – there were two generators.

Decommissioning and demolition
- Since April 2020, Barsebäcksverket has been undergoing dismantling and demolition. The dismantling process and removal of radioactive materials and large components within the plant will continue until 2028.
- The directives of the Swedish Radiation Safety Authority (SSM) continue to impose stringent requirements on our operations – we are still classified as a nuclear facility, even if the power plant is shut down and no nuclear fuel remains.
- We are also working with the handling and transportation of operational waste to the SFR final repository in Forsmark, and thereby continuously reducing the range of activities at the plant.
- We are also continuing with our sales operations – components that we no longer need can in some cases be reused in other nuclear facilities or for other industries.
