- Present state of scientific level for the given process.
- Present state of technical implementation of this scientific knowledge into PA.
- If the level of technical implementation in PA is lower that the level of scientific knowledge,
why is this the case (for example, tools not yet available, scientific knowledge not yet sufficiently
well rationalized or further development of technical implementation of that process
is irrelevant)?
- How can FUNMIG contribute to improvement in PA with respect to this process, if desired?
1 st Topical Session
The selected topics were:
- Scientific knowledge base of processes/topics and its implementation in PA from the point
of view of Waste Management Organizations, and
- Diffusion/retention in compacted clayey materials (Radionuclide migration in clay-rich host
formations).
The topics selected were at comparably advanced state of development with a sound scientific basis
in good progress. It therefore served as a good example for discussion of treatment in PA and the
expected contribution from scientific progress also in other areas.
2 nd Topical Session
Topics around disposal in crystalline rock were treated (RTDC4):
- Role of biogeochemical processes on radionuclide migration.
- Characterization of geochemical conditions in crystalline rock/ Process identification and
verification by real system analysis.
- Fluid flow system characterization in crystalline rock (Effects of the heterogeneity and upscaling)
Presentations within these topics covered a wide variety of different issues:
i Role of biogeochemical processes on radionuclide migration,
ii Effects of micro-organisms upon radionuclide migration,
iii Interactions of microbes with actinides,
iv Characterization of geochemical conditions in crystalline rock/ process identification and
verification by real system analysis,
v Results from the groundwater hydro-geochemical investigation program in Sweden,
vi Geochemical fluxes in the geosphere: quantitative understanding by identification and verification
of processes,
vii Fluid flow system characterization in crystalline rock (Effects of the heterogeneity and upscaling),
viii Effect of heterogeneities in transport and upscaling, and
ix Diffusion process within crystalline matrices: from petrography to solute residence time distribution.
3 rd Topical Session
The third topical session covered the “Influence of organics on radionuclide migration processes”.
It was co-organized by the RTDC 1 and 2 leaders. The following topics were presented:
- General overview on FUNMIG relevant organics with respect to mobile – immobile, natural
– waste derived organics, common FEPs concerning organics, and on starting point, investigations
and achievements on organics within FUNMIG.
