Quintessa and URS Corporation have developed groundwater flow models in the vicinity of the D1225 Shaft at Dounreay, a historic facility for Intermediate Level radioactive Waste (ILW). These models are to support the Post-Closure Safety Case for the Shaft following retrieval of the waste by feeding in to the revised hydrogeological conceptualisation at the district, site and shaft scales, recently constructed by Quintessa. The models will also act as predictive tools to assist in the design and installation of a low permeability grout curtain around the Shaft.
The groundwater models have been developed on two length scales:
The models will be constructed using the state of the art groundwater flow and transport modelling package 'FEFLOW' . For more information please contact Sarah Watson or Alex Bond.
