Objective
THE MULTIBARRIER CONCEPT FOR THE FINAL DISPOSAL OF RADIOACTIVE WASTES PROVIDES BACKFILL MATERIALS AND SEALS AS CONSTRUCTION COMPONENTS WITH THE PURPOSE TO PREVENT OR TO DELAY THE TRANSPORT OF BRINES TO THE WASTE CONTAINERS RESP. TO HINDER RADIONUCLIDES FROM REACHING THE BIOSPHERE VIA THE BRINE AS A CONSEQUENCE OF AN ASSUMED INCIDENT.
BACKFILLINGS ALSO HAVE TO ACT AS MECHANICAL STABILIZERS AND TO SERVE AS A "FILLING AGENT", I.E. BETWEEN WASTE CONTAINERS.
BACKFILL MATERIALS HAVE TO TAKE OVER A FUNCTION AS A BARRIER AT A VERY EARLY STAGE BECAUSE SO FAR THERE IS NO EXPERIENCE AVAILABLE ON THE LONG-TERM STABILITY OF CONSTRUCTIVE SEAL COMPONENTS.
IN A FIRST STEP TECHNICAL CONCEPTS FOR BACKFILLING OF UNDERGROUND "REPOSITORY ROOMS" WITH A SO-CALLED "REFERENCE BACKFILL MATERIAL" ARE TO BE DEVELOPED AND TESTED IN THE LABORATORY WITH SUPPORTING IN SITU TESTS.
1.1. SOIL MECHANICAL LABORATORY RESEARCH ON BACKFILL MATERIALS TO INVESTIGATE BACKFILL CHARACTERISTICS
1.2. GEOTECHNICAL IN SITU MEASUREMENTS TO DETERMINE THE INTERACTION BETWEEN ROCK SALT AND BACKFILL
1.3. PERFORMANCE OF GEOTECHNICAL IN SITU MEASUREMENTS AND ROCK MECHANICAL LABORATORY TESTS ON OLD, PRECONSOLIDATED BACKFILLINGS
1.4. DEVELOPMENT OF AN EVALUATION MATRIX FOR SELECTION AND USE OF SUITABLE BACKFILLINGS IN SALT FORMATIONS
2.1. INVESTIGATIONS IN THE LABORATORY ON THE MECHANICAL AND HYDRAULIC PARAMETERS OF SEALING COMPONENTS
2.2. SURVEYING SUPERVISION OF EXISTING CHAMBER AND GALLERY SEALING SYSTEMS AT THE ASSE SALT MINE
2.3. DEVELOPMENT OF AN EVALUATION MATRIX FOR SELECTION AND USE OF SUITABLE SEALING COMPONENTS.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
