FIELD: construction.SUBSTANCE: claimed invention relates to a construction method of repository for radioactive wastes. The declared method involves hole drilling in permafrost rocks, descent and cementing of an intermediate casing, arrangement of containers with radioactive wastes in the hole, sealing of the upper part of the hole. In the declared method, the intermediate casing is cemented in the range from the calculated boundary of the thawing zone up to the surface, and the containers with radioactive wastes are mounted on the hollow liner, perforated in the lower part, at a distancefrom the hole bottom, where h- interval height within which thawing of permafrost rocks happens; m - porosity of permafrost rocks; R- calculated radius of thawing; R- inner hole radius.EFFECT: provision of higher degree of reliability of radioactive waste disposal and exclusion of a possibility of radionuclide migration outside the repository.4 cl, 2 dwg |
