The Northwest of Russia faces the urgent necessity of establishing a regional RW repository.
The main challenge to the new facility will be the development and introduction of a system of advanced technological and organizational principles, and development of standard and reproducible approaches to the decommissioning problem.
Those RW management approaches which have proven their efficiency will be adjusted and used for other toxic waste.
As acknowledged by the IAEA, the most effective and safe solution of the RW final disposal is its burial in repositories at the depth not less than 300-500 m in the deep geological strata using the concept of multibarrier protection and mandatory solidification of LRW.

Geological formations of three types are suitable for the RW isolation from the biosphere:

• magmatic and metamorphic rocks;
• clays;
• rock salts.

RW repository option in the Baltic Russia

An option of a repository (controlled storage) for low- and medium-level waste is offered by Lenspetskombinat Radon (a waste-management company) located near Leningrad NPP, 1 km from the shoreline of the Gulf of Finland. By now the company, which runs the North-West storage of lowand medium-level waste, has accumulated more than 60000 m3 of radioactive waste kept in surface vaulted concrete storages.
In the opinion of A.A. Ignatov, LSK Radon Director, a possible disposal option can be offered by the Cambrian clay stratum under the company site. A trial borehole was drilled to the depth of 130 meters. In the opinion of Radon administration the drilling results confirm the feasibility of such an option; they are supported by the experts of SGN (France), AEAT (Great Britain), IVIE (Finland), SCK-CEN (Belgium).
It is known that the choice of a site can bring violent public protests. That is what happened in Gorleben (Germany), where the young people are actively protesting against the transportation of SNF from German NPPs to the repository made in the former salt mines. The public protests even resulted in casualties.
