The Development of Sprayed Backfill Technology
Original language description
The CEG, CTU in Prague has recently launched a sprayed backfill technology development programme. Such technology will, most probably, be used during the construction of deep underground radioactive waste repositories. With regard to the location in therepository in which the containers will be placed, bentonite will seal the space between the container and the rock mass in the form of a highly compacted bentonite block, while access galleries to the nests will be backfilled with a mixture of natural bentonite and rock. This mixture will be compacted in layers using compacting machinery. Following compaction, however, spaces will remain in the gallery vault to which such compacting machines will be unable to gain access. Sprayed clay technology, however, will allow the filling of such voids by injecting backfill so that the material compaction level obtained using this method is at least the same as the backfill compaction level resulting from that using standard compacting machinery.
