2019:07 General data in accordance with the requirements in Article 37 of the Euratom Treaty

Decommissioning of the Barsebäck nuclear power plant in Sweden

Abstract

The purpose of this report is to provide the European Commission with general data relating to plans for the decommissioning of the Barsebäck nuclear power plant, Barsebäck 1 and Barsebäck 2, that will enable the Commission to determine whether the implementation of the plans is liable to result in the radioactive contamination of the water, soil or airspace of another European Union Member state. The structure of the document follows the recommendations given in 2010/635/Euratom on the application of Article 37 of the Euratom Treaty.

Barsebäck 1 commenced operation in 1975 followed by Barsebäck 2 two years later. Both reactors were of the type boiling water reactors with a net electrical output 615 MW each. Barsebäck 1 and Barsebäck 2 were shut down permanently in 1999 and 2005 respectively, due to political decisions.

In 2006 the remaining nuclear fuel was transported off-site; since then Barsebäck nuclear power plant has been in Care and Maintenance operation and will continue to be so until 2020 according to current planning when dismantling and demolition is anticipated to start.

This report presents an assessment of the maximum expected emissions of radioactivity to air and water during decommissioning.

The assessment also includes a dose evaluation to a reference population living close to the power plant.

The dose to the reference group from radioactivity released during normal conditions at the plant is less than 0,003 μSv/year. As the dose to the reference group is less than 10 μSv/year, and there are no exceptional exposure pathways, no dose assessment is required for other EU member states.

The dose to the reference group from radioactivity released during a hypothetical radiological accident at the plant is less than 0,1 mSv.

As the dose to the reference group is less than 1 mSv, and there are no exceptional exposure pathways, no dose assessment is required for other EU member states.
