Dounreay as Dump site

uranium on its site. Concern about the prospect has been raised as a result
of plans to dig up historic waste held in a near-surface cluster of pits
near the DFR dome-shaped reactor. If the option is adopted, the material is
earmarked to go to the low-level waste dump, to the immediate east of the
plant. Dounreay Stakeholder Group (DSG) is concerned to ensure that this
would not include the long-lived radio-nuclides present in the pits. A
member of the group has calculated this could be as much as three-quarters
of a tonne of highly fissile uranium-235; a tonne-and-a-half of
uranium-238; and a kilogramme of plutonium. Given their half-lives stretch
into hundreds of thousands of years, DSG points out the substances would
easily outlive the designed lifetime of the dump.
