High Pressure Washing for Radiological Decontamination of Concrete Surfaces

Tender description

The aim of this project is to test the suitability of high-pressure washing procedures to decontaminate UK concrete surfaces contaminated with 85Sr, 137Cs, and 152Eu. This aim will be achieved by contaminating concrete coupons, sourced from the UK urban environment, under laboratory conditions. The depth of radionuclide contamination will then be determined so to understand the decontamination results (which will be generated at a later stage of the project). Thereafter, contaminated coupons will be decontaminated using high pressure washing and the extent of contamination removal will be measured. The successful Tenderer is not permitted to develop new high pressure washing equipment from raw materials. Rather, it is expected that the successful Tenderer will have access to existing high pressure washing capability that suits the specification requirements, either directly (i.e., “in-house” capability), or indirectly (i.e., renting equipment through the use of subcontractor(s)). Tenderers who intend to use subcontractor(s) to deliver this project are required to identify and provide these third-party organisation(s).
