Project summary

Purpose of the present Project is development and substantiation of main technical solutions on creation of ecologically safe, technically reliable and economically acceptable technology underground isolation of RW, formed in North-West and Far East regions of Russia, including compartments of out of service nuclear submarines and ice-breakers, and not meant for reprocessing SF, for technical designing of regional objects on disposal of RW and long-term storage of not meant for reprocessing SF in permafrost.

The present Project is a logical continuation and development of operations of ISTC Project # 057. It is suppose concrete definition of basic solutions, developed on the Project, and is an integral stage on the way of practical implementation of ecologically safe underground isolation of RW and not meant for reprocessing SF in North-West and Far East regions of Russia.

In the basis of technical approach to solution of the given problem lays the concept of underground isolation of RW in permafrost of Arctic geocriological region of Russia offered by VNIPIPT.

Earlier the concept was presented to state bodies and in 1992 was approved as a whole, including State Ecological Expertise of the Environment Ministry of RF, Gosatomnadzor of RF, Ministry of Public Health of RF, and also by mining technology section of scientific counsil of Ministry of Atomic Power of RF.

The first characteristic feature of the present project is the fact, that it is logical continuation and development of earlier conducted operations on ISTC Project # 057.

The second characteristic feature of the present Project is a system approach to solution of the problem of provision for safety during underground isolation of RW and SF in permafrost through the whole technological chain, beginning from preparation of RW and SF for underground isolation, subsequent transportation and finishing with disposal of RW and long-term storage of SF. Development and acceptance of separate inpidual solutions on any concrete stage of operations can result in that the implementation of other stages of operations will be technically impossible, economically unjustified or ecologically dangerous.

The third characteristic feature of the present Project is its trend on creation of concrete objects on underground isolation of RW and SF. First of all it concerns (in decreasing order of degree of study and preparation for creation):


· test-industrial object on Southern island of the Novaja Zemlja archipelago in the region of settlement of Bashmachnyi for underground isolation of RW and not meant for reprocessing SF, large-sized radiation-dangerous equipment, formed in North-West region of Russia while operating nuclear fleets;
· test-industrial object in region of Bilibino NPP (Chucchi) for underground isolation of RW and SF, formed during operation and possible conservation (taking into account earlier conducted detailed engineering and geological survey of the site for Bilibino NPP construction);
· and in prospect test-industrial object in the region of Okhotsk or Bering seas’ coast for underground isolation of RW and SF, formed while operating nuclear power installations of Pacific ocean fleet of Russia.

Potential Role of Foreign Collaborators

Following foreign firms have expressed desire to work as collaborators under the Project:


· German community on building and exploitation of definitive farms of wastes - DBE;
· Finnish Center for Radiation and Nuclear Safety - STUK;
· AEA-Technology (Great Britain).

By operation with collaborators it is supposed:


· to carry out interchange with information on implementation of operations under the Project;
· to carry out meetings of specialists with the purpose of exchange of practical expertise of operation on disposal of radioactive waste;
· to institute opportunities of conducting of joint operations on two-sided basis.
