Concrete from decommissioned nuclear sites should be reused to fill in voids after reactors are demolished, an Aecom-led report concludes. The Nuclear Decommissioning Authority (NDA) tasked Aecom with the research, which was included in the NDA’s Direct Research Portfolio Annual Report for 2018-19. It is estimated that the Magnox reactor sites will generate 1.3M.t of concrete during demolition. Removing this for disposal at landfill sites would require 140,000 truck movements, at an estimated cost of almost £150M. Instead, Aecom’s report suggest concrete reuse on site would minimise the need to transport rubble elsewhere for disposal and to bring in other materials for void infill or landscaping. This would save time and costs, and minimise environmental damage.
