Network to review natural analogue studies and their applications to repository safety assessment and public communication
ID: FIKW-CT-2002-20204
Start date: 2003-01-01, End date: 2004-12-31
The aim of this project is to promote a more considered use of natural analogues in safety assessment and public communication. This will be achieved by a critical review of traditional analogue studies, such as investigations of radionuclide transport around uranium ore bodie...

Plate test - In-situ test at Mt Terri
In the underground laboratory of Mont Terri, a comprehensive study of the EDZ has been carried out. The observed induced fractures, which generally have been created under local tension, led to an increase of the local permeability (several orders of magnitude) in the vicinity...

Long term evolution of the EDZ around a gallery - In-situ test at Mol (HADES)
A new gallery was realised to extend HADES. In-situ test 3 consists in studying the evolution in function of time of the hydro-mechanical properties within the EDZ around the gallery during a period of three years after its construction. For this purpose two multi piezometers ...

State of the art on fracturation and self-healing processes and characterisation
A review and reporting of the state of the art on basis of existing theoretical studies and in situ observations realised in underground laboratories has been performed. A clear distinction has been proposed within the SELFRAC project, between the Excavation Damaged Zone (ED...

Conclusions on the long-term performance of a nuclear waste repository in respect of the EDZ zone around excavation - Synthesis report
Performance Assessment is concerned with the potential radiological consequences of the disposal system. Hence, the analysis of the evolution of the repository system, of which the EDZ is a part, is an essential part of PA. The EDZ is initiated during the repository constructi...

EDZ along a borehole - Insitu test at Mt Terri
The most important parameter for performance assessment to be measured in the EDZ is the axial transmissivity along tunnels, as this preferential flow path could act as a shortcut for radionuclides. All tests performed so far are designed to measure the local effect of fractu...

Numerical simulation of the EDZ and of the self-healing around an excavation
The modelling of the excavation process and the strain localization prediction along the process has been performed using the finite strain Finite Element Code Lagamine, with the constitutive law CLoE. A special modelling procedure was designed, taking into account the progres...

EDZ and self-healing along a borehole - In-situ test at Mol (HADES)
In-situ test 4 is quite similar to in-situ test 2 but for Boom Clay. The natural closure of a borehole is studied. Permeability and possibly seismic measurements were performed to follow the evolution of flow properties through the borehole. The testing is performed in the fo...

Fractures and self-healing within the excavation disturbed zone in clays
ID: FIKW-CT-2001-00182
Start date: 2001-12-01, End date: 2004-11-30
As in all nuclear power generating countries, high and long-lived radioactive waste management is an important environmental issue today. Underground storage in deep clay geological formation is one of the promising options to dispose these wastes. An essential item for the lo...

A thematic network on gas issues in safety assessment of deep repositories for nuclear waste
ID: FIKW-CT-2001-20165
Start date: 2001-09-01, End date: 2004-02-29
Repositories for nuclear waste are expected to produce gases as a result of a variety of chemical, microbiological and radioactive decay processes. Assessment of the impact of the generation and migration of gas is recognised to be an important element of any safety case for t...
