An independent review is being carried out of the specifications, execution and results of Task 6 of the Äspö Task Force on Modelling of Groundwater Flow and Transport of Solutes, which is seeking to provide a bridge between site characterization and performance assessment approaches to solute transport in fractured rock.
A review of sub-tasks 6A, 6B and 6B2 has recently been published , related to the transport of tracers on a 5-metre scale in Feature A at the TRUE-1 site.
The task objectives, specifications and individual modelling team results were summarised and reviewed, and an evaluation of the overall exercise was presented. The report concludes with assessments of what has been learnt, the implications for the Task 6 objectives, and some possible future directions.
