Unresolved questions regarding the problem of spent fuel isolation also exist in other countries that use electricity produced by atomic power plants. At present, spent fuel storage facilities at many Russian atomic power plants and nuclear fleet bases in the country's northwest and east are filled to planned capacity or nearly so.

Another characteristic of the PMCPA region is the fact that it has been the subject of detailed geological studies carried out in the course of many years of large-scale, comprehensive prospecting efforts, which have included geological and geophysical studies, enormous volumes of test drilling and underground mining operations, and other extensive scientific research work. The many years of mining operations that continue to this day represent a significant source of geological information.

For these reasons they are not suitable for underground storage of radioactive materials. The same holds true for Mesozoic sedimentary rocks.

In the overall massif the task is to locate and study weakly violated geological blocks of the required size and then install in the most suitable block all the necessary facilities and support structures for an underground spent fuel storage facility. DESIGN FEATURES OF THE FUTURE REPOSITORY AND PROMISING SITES FOR ITS CONSTRUCTION Given the characteristics of the surface landscape and the environmental, technical, and economic conditions as well as security considerations, a gallerytype underground repository appears to be the most suitable for the reliable isolation of spent nuclear fuel under the conditions prevalent at PMCPA.

It is commonly known that the safe long-term storage or burial of nuclear materials is ensured only by means of their complete isolation from the hydrosphere or if the repository is located in a water-saturated zone, by the restorative properties of the underground waters circulating in that zone.

This option also involves the use of gallery-type facilities, which could be not only outfitted with structural features for the short- and medium-term storage of spent nuclear fuel but also provided with special mechanical equipment for the drilling of a "blind" shaft or a spiral descending tunnel. These structures could be used to create a facility for the long-term storage of spent fuel or the burial of highlevel radioactive wastes at a depth necessary to meet safety requirements.

Production activities in these areas as well as efforts to study the geology and uranium content of the Streltsovskoe ore field and specific deposits have always been accompanied by intensive scientific research efforts. Specialists from the leading institutes of the Russian Academy of Sciences and applied research institutes of Minatom and the Russian Ministry for Natural Resources have participated in these efforts, along with enterprise personnel.

Four sites viewed as promising for the placement of an underground high-level waste storage facility have already been identified in the thick, hard, and poorly permeable rock formations (granitoid gneisses, granites, shales) adjoining most of the enterprise's grounds.
