BACKFILLING AND CLOSURE OF THE DEEP REPOSITORY. ASSESSMENT OF BACKFILL CONCEPTS ABSTRACT This report presents the results from work made in Phase 1 of the joint SKB-POSIVA project "Backfill and Closure of the Deep Repository" aiming at selecting and developing materials and techniques for backfilling and closure of a KBS-3 type.

The main conclusions and results from this project are presented in this report. Introduction. Bentonite clay and quartz sand have been selected as potential buffer and backfill materials for high-level radwaste disposal (Jedinakova-Krizova, ).The functional requirements of buffer materials consist of both engineering and chemical properties (JNC, ; Yong, ).The engineering properties include: (a) preventing Evaluation of Backfill Materials For A Shallow-Depth Repository.

Unsuitable material is organic, usually wet, black, and extremely weak (Figures 21 & 22). It is incapable of supporting any significant load. Improperly treated unsuitable materials will settle for many, many years.

The unsuitable material is usually removed and replaced with suitable material before the embankment is constructed. compact backfill around and are more likely to have settlement problems (para a).

Although the multilevel step structure (fig. a) is not particularly difficult to compact backfill around, at least for the first level, the compaction of backfill over the offset structure will generally require the use of small equipment.

The use of commercial by-products, such as furnace slag or fly ash as backfill material, may be advantageous where such products are locally available and where suitable natural materials cannot be found.

Because the functional requirements of buffer–backfill materials for high-level radwaste disposal consist of both engineering (e.g., hydraulic conductivity, mechanical properties, swelling, etc.) and chemical properties (e.g., sorption, pH buffer capacity, etc.) (Jedinakova-Krizova,Yong et al., ), it is very important to understand how both engineering and Cited by: 4.

Deep Geological Disposal of Radioactive Waste presents a critical review of designing, siting, constructing and demonstrating the safety and environmental impact of deep repositories for radioactive wastes. It is structured to provide a broad perspective of this multi-faceted, multi-disciplinary topic: providing enough detail for a non-specialist to understand the fundamental principles.

Long-term science and technology program: an ongoing program to improve the scientific understanding of the geologic repository system. The program includes scientific activities to (1) update the safety case, (2) investigate engineering alternatives to optimize repository design, and (3) and confirm (or invalidate) previous assumptions, data, and analyses.

Bentonite is currently planned for use as a buffer and backfill material for repositories of high-level nuclear waste because these materials must have swelling characteristics to seal the waste.

However, it is necessary to choose the appropriate bentonite from among many kinds of bentonite in the design of buffer and backfill materials. of backfill with vibratory or other accepted equipment on granular backfill material.

Backfill materials surrounding waste canisters in a high-level nuclear waste repository are capable of ensuring very slow flow of groundwater past the canisters, and thereby increase the safety of the repository. However, in the design of a repository it will be necessary to allow for possible changes in the backfill.
