Project summary

The objective of the Project is to perform an assessment of the influence of radioactive wastes and materials dumped at sea as well as those located at decommissioned nuclear submarines and storages of spent nuclear fuel on the actual and potential radioecologic situation in seas adjacent to the territory of Russia and to issue recommendations on rehabilitation of dangerous objects.

The objective of the Feasibility (Preliminary) Study was to specify the place and specific contribution by the Project to the on-going international activities on the problem of radioecologic hazard in seas surrounding the RF. As a result of the Feasibility Study the ISTC and the Project funding parties acquired a clear notion of the urgency and necessity of the Project, of the possible participants and obtained data for justification of the requested funding and schedules of the work.

Research of the problem at the Feasibility Study phase has shown that the problem of radioecologic situation in the seas surrounding the territory of the RF is still extremely urgent for the world community while the extent of danger remains non-identified. At the current phase of crucial importance is the true information about sources, scientific Justification of risk assessment and a sound and weighted approach to identification of priorities for adoption of optimum and effective measures under the lack of funding.

Actually these are the primary purposes which Project 101 participants are striving to achieve.

As coordinated with the ISTC the first draft Work plan for the major project was submitted as an intermediate report of the Feasibility Study .It enabled to develop the final version of the Work plan which takes into account the opinions, remarks and suggestions of the ISTC and EC experts as well as the ones of inpidual scientists and leaders of international programs by the beginning of October.

It is possible to say that Project 101 has made scientists and specialists interested. A considerable number of the letters of support and proposals to cooperate were obtained. Major approaches to Project 101 have been coordinated due to specification of the following aspects:

1. Trends (directions) of research taking into account the work which is underway within other programs;

2. The scope, cost and the time limits of major phases as well as work duration;

3. Specific principles and ways to provide compatibility of computer systems of databases, composition of hardware and software of the future Computer Center;

4. Degree of completeness of information entering the database;

5. Methods of trustworthiness control and quality assurance of the database being compiled.

The original (first hand) information was received from the Navy of RF about location of all decommissioned and subject to utilization nuclear submarines with indication of the status of reactor cores.

As demonstration examples the information was collected, processed and will be submitted in the final report about the radioactivity sources dumped in the Kara Sea, i.e. the shielding assembly of the ice-breaker LENIN and reactor with the unloaded core of submarine factory No. 421.

At the Feasibility Study phase organizations possessing information about radioactive contamination sources and the marine environment were identified. Confirmations of agreement to submit the available information for its selection and entry into the database were obtained. Funds in the form of grants were planned for participants of these works.

The original information will be normally presented in the text, table and graphic format. After processing the analytical group of the Center will transfer it for entry into the database in the format of electronic tables, texts and graphic material as well as photos and videofilms.

After execution of appropriate calculations in accordance with methodology used by OKBM, NIKIET and HYDROPRESS the secondary information will be transmitted to the Computer Center of CDB LAZURIT.

The main condition is not only completeness, accuracy and reliability of the collected data but also provision of trust on behalf of scientists. The procedure to prepare the database envisages compulsory availability of references to documents and possibility of selective control by experts.

The work to collect data is planned to be started with dumped at-sea objects which will be a continuation of work started at Feasibility Study Phase. According to the opinion of EC experts this will be a good starting point to check the procedures and speed up follow-on phases.
