The paper briefly presents the problem aspects on power supply for the remote and inaccessible regions of Russia. Reactor units of different type and installed electric capacity have been considered in relation to the issue of power supply during mineral deposit development in the Chukotka autonomous region, Yakutia and Irkutsk region. Some preliminary assessment of the possible options for use of small nuclear power plants in various sectors of energy consumption have been carried out based on the analysis of different scenarios for economic development of the regions considered

Стратегические подходы к решению экологических проблем, связанных с выведенными из эксплуатации объектами атомного флота на Северо-Западе России

The results of investigations of the safety validation of an underground regional burial site in the northern region of our country as part of the TACIS project are presented. The methodological approaches are described, and the initial data on the activity level of ecologically significant radionuclides and models of the burial site (near and far fields, biosphere) are presented. The results of numerical experiments are discussed. These experiments made it possible to draw a preliminary conclusion about the acceptibility of the sites considered for burying wastes and the preferred site Dal’nie Zelentsy, located at the center of the Murmansk geological block.

The paper provides an assessment of the problem, which presents the management of spent nuclear fuel (SNF) from ship nuclear power units (NPU) in the north-west region of Russia and suggested is a concept of solving the problem. The concept is based on the utilization of the regional underground storage facility for long-term storage of defective, damaged and other kinds of SNF that can not be reprocessed.

The North-West region of Russia has accumulated large amount of radioactive waste. Underground storage of this waste is considered to be the best solution of this environmental problem. Deep formations of hard crystalline rocks of the Kola peninsula are regarded as logical potential sites for construction of a system of underground disposal facilities. Several potential sites are considered for detailed investigations.
