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 17 November, 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. The total cost of the project, including operation and closure, is expected to be the region of GBP 100 million.
