Operation of the Swedish sea transportation system for spent fuel

At PATRAM 83, the Swedish Nuclear Fuel and Waste Management Co. (SKB) presented a paper on ''The realization of a sea transport system for radioactive material''. Some information was also given on the very first experience of the transport of some 35 t of uranium between Sweden and France. Since 1 March 1985, M/S Sigyn has been sailing under the Swedish flag and operated by the Swedish shipping line, Rederiaktiebolaget Gotland. The Swedish AFR facility CLAB was put into active operation in July 1985, with a receiving capacity of 300 t of uranium per year and a storage capacity of 3000 t of uranium at present. During the first year of operation CLAB received 250 t of spent fuel. The paper describes experience based on 16 sea voyages and the reception in CLAB of about 80 casks with spent fuel from Swedish nuclear power plants. The CLAB facility is equipped with a cask maintenance workshop, where preventive maintenance, re-inspection and repairs are carried out. (author)
