Dounreay Site Restoration Ltd (DSRL) is planning to undertake the construction of Dounreay radioactive waste disposal facility project in Scotland, the UK.
The project involves the construction of series of underground concrete vaults that will receive up to 240,000 tons of low-level radioactive waste.
It includes the construction of six underground vaults, an agricultural-style building, a grouting plant and other infrastructure related facilities.
The project is being implemented in four phases, with vaults only being constructed when it is deemed they are required. Each phase includes the construction of two low level waste vaults and each vault will cover an area about 1.8ha and will be 20m deep.
An agricultural-style building will be built over each vault to provide cover during its operation, before each is finally backfilled with grout and capped.
The first phase of the project included the design and construction of two underground concrete vaults for the disposal of solid waste from the site clean-up. The two concrete vaults of approximately 80m long, 45m wide at a depth of approximately 20m.
The second phase will be confirmed as the site decommissioning progresses and waste volumes are updated. DSRL has identified that at least two further vault will be needed. The timescale for construction has still to be determined.
The third phase vaults would be needed to cater for LW arising from the possible retrieval of waste from the existing disposal facility at Dounreay. The fourth phase will involve sealing the vaults, backfilling the excavation around the vaults, emplacing engineered caps over the vaults, and merging the caps with the enhanced geosphere layer. The area will then be restored to blend in as far as is practical with the surrounding environment.
In 2006, a planning application was submitted to Highland Council, with an updated application submitted in 2008. However, planning permission for these facilities was granted in April 2009.
In January 2011, the Northern Ireland construction group, Graham won a Design Build contract for the first phase of the project.
Graham construction is also constructing the agricultural-style building and the grouting plant.
I&H Brown and Mott Macdonald have been appointed as lead consultants and Walter Watson and BHC as steel supply contractor.
DSRL has planning permission to build six vaults, however this will depend on the demand.
In November 2011, construction activities on the first phase of the project commenced and completed in May 2014.
The project involves the construction of series of underground concrete vaults that will receive up to 240,000 tons of low-level radioactive waste at Dounreay in Caithness, Scotland, the UK.
The US$157 million project includes the following:
1. Construction of six underground concrete vaults
2. Construction of an agricultural-style building
3. Construction of a grouting plant
4. Construction of related facilities
