Figure 1: Structure of task mapping and evaluation
The host rock specific Task Evaluation Tables contain the task titles, the FEP numbers the tasks are
mapped to, affected safety assessment parameters and, most importantly, the standardised evaluation
information consisting of a researcher’s view and a WMO’s view. The TETs are included in
the final RTDC 6 report on “FUNMIG topics and processes and their treatment in the safety case”
[6].
Having completed the the TETs the synthesis depicted in Figure 1 was carried out by lumping together
the individual FEPs (to which FUNMIG tasks were mapped) to “Super-FEPs” such as
“Transport mechanisms” or “Retardation”.

Mutually applicable knowledge, mutual benefits
Because the outcome of FUNMIG was evaluated on a task level the reporting of the comprehensive
results is beyond the scope of the present paper due to the extensiveness; in this regard we refer to
the Task Evaluation Tables in the final RTDC 6 report on “FUNMIG topics and processes and their
treatment in the safety case” [6]. Although the programme and site specificity of the evaluation results
is evident, there is a considerable agreement between the performance assessors within a host
rock type. Topics, judged by the performance assessors to be particularly important, are listed below.
For clay-rich host rocks topics of high relevance for future safety cases with important progress
within FUNMIG are
The understanding of diffusive transport in clays, namely
o Differences between anions, cations and neutral species,
