Decommissioning concepts for the norwegian nuclear research facilities Halden and Kjeller - 15022
The Norwegian nuclear research facilities Halden and Kjeller are near the end of their current operational licenses. Thus, the Norwegian Ministry of Trade, Industry and Fisheries have decided that a concept evaluation study shall be made on the decommissioning alternatives for these facilities. This task was given to Ndcon (Westinghouse and Studsvik) with their broad experience in decommissioning planning and decades of nuclear expertise, together with DNV GL, that is certified in Norway for concept evaluation studies. The decommissioning alternatives that have been evaluated are strategy, end-state and waste management options. The decommissioning strategies are the IAEA defined immediate dismantling, deferred dismantling and entombment. The different end-states that have been evaluated are unrestricted use (green field), light industry (brown field) and other nuclear activity, in which the site will continue to have a nuclear license even after the decommissioning. The waste management options are direct disposal of materials, recycling of materials off-site and recycling on-site. The result of the cost estimation is that it is possible to identify viable alternatives for a chosen decommissioning strategy, end state and waste management options. The expected duration of the decommissioning program is 10 years for both sites, the dismantling and demolition period is expected to be able to perform within 4 years. (authors)
