Results of FracAffinity such as 3D head field, rock mass property interpolations, stochastic fracture models and pathlines may be visualised alongside the geological framework upon which the simulation is based. Radioactive Waste Disposal Models and Software QuantiSci have developed various models for use by our Japanese clients. The H12 performance assessment published by PNC in 2000 used QuantiSci s Meshnote code for the waste canister and bentonite buffer and Amber for the biosphere. Both codes include a full set of decay and transport processes, with zonal time-dependent properties allowing a wide range of geometries and scenarios to be considered. Outputs in terms of doses can be produced.
Tiger uses a network model of the far-field to allow branching paths to be treated.
Nestor allows a wide range of source models, including some with internal discretisation. In Tiger, the effect of evolving geochemical conditions can be modelled. Both codes use our general-purpose equation solver, Dylan . In some cases a more detailed research model is required. QuantiSci have developed mathematical models to look at complex processes and heterogeneous environments.
