Today, all the nuclear fuel, which contained most of the radioactive substances, has been transported away from Barsebäck Nuclear Power Plant. Reactor tanks and other major parts must be disassembled and transported away before the buildings themselves are dismantled. The aim is to try to remove the largest components possible in order to ensure the process of dismantlement will be efficient.
Meet Pia who works with the dismantlement of Barsebäck
Barsebäck Krafts mission is to complete the area as industrial land with a level four meters above sea level.
The company is owned by Sydkraft Nuclear Power (SNP), which is included in Uniper. SNP also owns Barsebäck Nuclear Power Plant and the land on which the plant sits and it and has the responsibility for the dismantling of the plant.
The cost of the dismantling will be covered by funds. During operation, nuclear power plants set aside approximately 1 Swedish öre per kilowatt hour produced for state dismantlement funds. The current service operation period is being financed by compensation from the state due to the early shutdown of the plant.
The major ongoing project is the segmentation of the reactor internals. They are currently stored in shielding steel boxes in our interim storage. The project will finish in early 2019. The next large project will be removal of the reactor vessels.
When we start to dismantle all the radioactive material in the plant there will be a large amount of different sorts of waste, both radioactive and conventional. All the waste must be measured and categorized. First the level of radioactivity will be checked and then it will be sorted according to which type of material it is, for instance concrete, sand or metal. If it is radioactive it will be packed in different sorts of transport containers and then sent to either further treatment or for final repository. If it is not radioactive, which will be the largest amounts, it will be sorted in categories of conventional or hazardous waste. The conventional waste might be recycled to further use on site or transported away for other recycling. Hazardous waste will be sent for final treatment at acknowledged recipients.
After the radiological dismantling
When all the radioactive material has been removed from inside the plant it can be realesed for conventinal dismantling. We have then showed the regulatory bodies that the level of radioation is not above the natural background radiation in the surrounding area. It is then time to start the large scale dismantling of buildings and the site in general. Much of the waste that will be generated at this stage will be reused on site, for example crushed concrete will be used as backfilling.
Our mission is to decommission the site to brown field, which is further industrial use.
