The contract was awarded by Dounreay Site Restoration Limited (DSRL), which is responsible for decommissioning the former centre of fast reactor research and development in Caithness.

The new plant is a key link in the chain to enable the retrieval, processing and packaging of waste from the Dounreay Shaft and Wet Silo. The overall objective is to make the waste safe for long-term storage and disposal.

The scope of work includes concept and detailed design, manufacture of the modular process plant, offsite testing, delivery to the Dounreay site and onsite installation and commissioning.

Liquid effluent from the new plant will be managed, processed and discharged by pipeline to the existing low level liquid effluent treatment plant.

DSRL is a wholly-owned subsidiary of Cavendish Dounreay Partnership – a consortium of Cavendish Nuclear (50%), CH2M (30%) and Aecom (20%).
