PROJECT RESULTS / Annual Technical Results
Year 2 : ESDRED TECHNICAL RESULTS to January 2006
Module 1: Buffer Construction Technology for Horizontal Disposal Concepts
Summary :
During the second year of the project the various buffer materials being considered have been formulated and characterized at a sufficient level of detail. The preliminary tests and modelling, implemented to check the relevancy of material performance or emplacement technology, have delivered conclusive results, paving the way for undertaking the “Demonstrations at an industrial scale” phase. All of the design and most of the fabrication related to the industrial scale demonstrations is either complete or is ongoing. Also the Partners have agreed on the nature of the non-intrusive monitoring test programme to be run and on the location of this experiment (Mont Terri URL in Switzerland). Currently, the test equipment has been installed and a first measurement campaign has been undertaken (end of 2005).

o Actual start up of the SB experiment in the Mont Terri URL
o Finalization of the buffer material saturation testing on mock-up in GRS laboratory in Braunschweig
Mock-up for SB buffer material saturation test
Important Events Planned for 2006 :
- ANDRA: fabrication of the prototype buffer rings using the Aubert & Duval press
- NAGRA: granular buffer emplacement demonstration testing on wooden mock-up
NAGRA’s “wooden model” - NIREX: first measurement campaign of the non-intrusive monitoring in-situ test
