Tender: Feasibility Study for Ion Exchange Treatment of Dounreay Wet Silo Liquor

About

NRS Dounreay is seeking a supplier for a feasibility study to develop a modular ion exchange treatment capability for liquor held in the Dounreay Wet Silo. The study will provide consultation and support for silo liquor sampling, use analytical data to develop a suitable ion exchange treatment process, perform or direct inactive and active liquor ion-exchange processing trials to underpin a modular treatment plant design, and produce a feasibility report documenting the development and proposals including an outline concept of the plant. The silo contains solids and sludges stored under water in a below-ground vault split into two hydraulically linked compartments, with liquor volume estimated at 150–200 m3.
