Nuclear decommissioning in Sweden: A priority for the 2020s

Nuclear Decommissioning at Sweden’s Barsebäck Nuclear Power PlantUniper Prepares For Nuclear Decommissioning in SwedenRinghals: Decommissioning of Sweden’s Oldest PwrRegulatory Perspective on Nuclear Decommissioning in SwedenFunding and Nuclear Waste Disposal in SwedenThe twin units at Barsebäck, a few miles across the straight from Denmark, ceased to generate power in 1999 and 2005, respectively. After shutdown, all spent fuel was removed and shipped to Sweden’s central interim storage facility (Clab) in Oskarshamn. Major decontamination of systems was also done early. However, dismantling had to wait, due to a lack of facilities for storage or disposal of decommissioning waste. In lieu of generating power, Barsebäck put its facilities to other good uses while awaiting dismantling. Barsebäck became a training ground for staff from other sites, and spare parts were sold. Conventional areas were leased out to local companies as office or storage space. The site’s information centre remained open and thousands of people each year have taken walking tours through the facilities. In parallel, options for interim storage of decommissioning waste were explored. By 2016, a new on-site store for low- and intermediate-level waste had been built at Barsebä...Get price
