Decommissioning of the nuclear reactor Ågesta in Sweden.
The purpose of this report is to provide the European Commission with general data relating to plans for the decommissioning of the pressurised heavy water reactor Ågesta, situated outside Stockholm, Sweden, which 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.
The Ågesta reactor was Sweden's first commercial reactor. The reactor is a pressurized heavy water-moderated reactor and is located in a rock cavern. The reactor was in operation between 1964 and 1974, and in addition to generating electricity, heat was produced and delivered. The reactor output, after some modication of the core in 1970, was 80 MWth and 12 MWe.
Since 1974, the Ågesta reactor has been in care and maintenance phase. Fuel and heavy water were removed from the site in the 1970s.
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 0,001 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 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.
