Dounreay Site Restoration Ltd has short-listed five companies to compete for a contract to design and build a disposal facility for low-level radioactive waste from the decommissioning of Britain’s fast reactor experiment.

The five companies were short-listed from 12 who expressed interest in a contract notice issued by DSRL in March.

The short-listed companies (with their nominated sub-contractors) are:

  • BAM Nuttall (BAM Ritchies, Halcrow, Golder Associates)
  • Black & Veatch (John Gunn & Sons, Coopland Consultancy, BMT Cordah, Serco)
  • Graham Civil Engineering (I & H Brown, Mott Macdonald)
  • MBM, comprising Morrison Construction, Balfour Beatty and Morgan Est (Scott Wilson)
  • ROK Construction (Atkins)

The selected tenderers have visited the site of the proposed facility adjacent to Dounreay and are due to return at the end of September. The deadline for return of tenders is November 17, with a contract award expected by the end of March 2011.

The successful contractor will design and build two sub-surface vaults initially for the disposal of solid LLW from the decommissioning of the site.

Decommissioning of Dounreay and the adjacent Vulcan nuclear facility is expected to produce up to 175,000m3 of solid LLW, including 38,000m3 of waste due to be retrieved from a series of disused disposal pits on site that date from the 1950s.

DSRL is applying the “waste hierarchy” principles to reduce the total volume of waste generated during decommissioning and so reduce the total number of vaults that need to be built. The site has planning permission for up to six vaults.

Up to 100 jobs will be created during the construction phase of the project. The total cost, including operation and closure, is expected to be the region of £100 million.

Site preparatory work and an archaeological survey begins this month. This includes laying of site access roads, using hardcore from recycled material excavated during decommissioning work. Redundant cabins from the decommissioning site are to be used as construction offices at the LLW site.
