The present projects running at the GTS are focusing on:
- Development and optimisation of the technology, transporting, emplacing, quality-assuring, monitoring and, if required, retrieving of radioactive waste.
- Extending past studies of processes in the geosphere, mainly associated with radionuclide mobility, to more closely represent the physical scales and boundary conditions relevant to repository environments.
- Monitoring and extending the knowledge and experience available from the present generation of radioactive waste experts by training the next generation who will actually build repositories.
CFM Project
The CFM (Colloid Formation and Migration) project aims to enhance understanding of the processes related to colloid formation at the bentonite/host rock interface.
C-FRS Project
The aim of C-FRS (CRIEPI’s Fractured Rock Studies) in-situ experiments at the GTS is to demonstrate the performance of newly developed technology for fracture characterisation and tracer testing.
CIM Project
CIM (Carbon-14 and Iodine-129 Migration in Cement) aims to simulate the transport of C-14 and I-129 through aged cementitious backfill of a L/ILW or TRU waste repository and into the saturated host rock.
ESDRED/TEM Project
ESDRED/TEM investigates the efficiency of an existing wireless magneto-inductive transmission technique and evaluates seismic tomography as a non-intrusive monitoring technique.
FEBEXe Project
FEBEXe continues FEBEX and helps predict nearfield evolution, including thermal conductivity, thermal convection, corrosion and gas production, gas transport capacity, and geochemical evolution.
FEBEX-DP Project
FEBEX-DP dismantles the FEBEX experiment and supports characterisation of key physical properties of the barrier and their distribution.
FORGE Project
FORGE aims to obtain larger-scale, decimetre-scale, two-phase flow properties for host rock and engineered barrier system materials.
GAST Project
GAST (Gas-Permeable Seal Test) aims to demonstrate the effective functioning of gas-permeable seals at realistic scale and with realistic boundary conditions.
HotBENT Project
HotBENT aims to evaluate accepted safety functions by investigating the effects of high temperatures on bentonite-based barriers.
ISC Project
ISC aims to improve understanding of geomechanical processes during hydraulic stimulation, induced seismicity, and the efficiency of generated underground heat exchangers.
LASMO Project
Large Scale Monitoring aims to test monitoring systems, technologies and methods, and to collect monitoring data to identify baseline conditions and disturbing events.
LCS Project
LCS aims to increase understanding of high-pH cement interaction effects in the repository near field and geosphere to support robust safety-relevant predictions.
LTD Project
The LTD (Long Term Diffusion) project provides quantitative information on matrix diffusion in fractured rock under in-situ conditions.
MACOTE Project
The Material Corrosion Test consists of non-heated and heated experiments to study in-situ corrosion of candidate canister materials embedded in bentonite.
NF-PRO Project
NF-PRO is a laboratory programme performed on two granite cores from the GTS, aimed at optimising probe design and interpretation of TDR measurements.
PSG Project
PSG studies changes in rock structural properties during sampling by comparing preserved in-situ pore space with samples drilled and taken to the laboratory.
