Some parts of foreign research can be used. In spite of that, each state must carry out its own specialized research with regard to the specific conditions in different geological environment and locally provided sealing materials. For safe isolation of high radioactive waste it will be necessary to solve many special engineering and other problems. There are also complicated demands for the deepdisposal constructions' reliability for 100 thousands to 1 million years. Using highly compacted bentonite prefabricates is one way of filling the area between the host rock and the container with waste. The aim of the project is (with using foreign experience and international cooperation) to carry out the prefabricated bentonite barriers research with regard to the necessary longtime results' extrapolation.
