Project summary

The project belongs to a category of applied studies.

The main goal is the development of new models of radioactive waste (RW) and contaminated materials handling for decontrol and concentration.

In the course of the project the following activities are assumed:

1. Development of statistical models and calculation of permissible contamination levels of materials exempted from control.

2. Examination of possible directions of economic usage of low-level contaminated materials exempted from control.

3. Development and research of technological models of RW concentration with sediment formation having a special complex of properties for disposal by means of saline compositions (Principle of packing) with increased inactivity (Principle of isolation) and bacterio-static action.

4. Demonstration of operational capabilities of new waste handling models on practical tasks, such as:

– re-melting of radioactive metal wastes in a power-metallurgical reactor with liquid-metal cooling system;
– cleanup of contaminated surfaces of structural units by means of microwave generator;
– production of new type of sediments of 90Sr with a special complex of properties and usage of the basic results for other radionuclides in the process of reduction of liquid RW volume;
– separation of contaminated suspension for spent LCL into pure and "dirty" handling fractions;
– usage of colloid-chemical extraction of microelements from aqueous solutions.

The selected models of waste handling should be a basis for the development of new technologies and means of RW volume reduction and also formation Of RW in safer structures.

The results of the project:

– will be of interest to regulatory bodies of various countries, as calculation of permissible contamination levels through the united technique will allow the creation of a basis for the development of a common decision in the countries interested in the establishment of internationally approved standards for exemption of low-level materials from control;

– will reveal directions, which have a commercial potential to become a basis for long-term economic assistance to scientists and engineers and to support conversion of commercial-technical activities from military to civil purposes.

The principled novelty of the proposed decisions is of considerable interest with regard to waste utilization, intermediate storage and near-surface disposal and will make a contribution to development of common approaches and strategy of safety principles. A further development of the project will concern the implementation of the developed models in experimental laboratory procedures and technological techniques of RW handling.

The medico-preventive aspects of medical physics will be developed, in particular, as the accompanying direction. These aspects concern creation of both prophylactic remedies for concentration of toxic metals and radionuclides in the human organism in a form suitable for extraction, and transport media to transfer medical agents to the affected organs.

The participants of the project have a great potential and experience in theoretical and applied physics, radiochemistry, physical and chemical analysis, as well as in composite material study and theoretical physical metallurgy. The project provides for the participation of many specialists previously involved in the improvement of nuclear weapons and radioactive waste handling, as well as in radiobiology and defense technologies. In some studies of the authors of the project there are positive results for the specific cases of the problems concerned. This fact confirms the necessity and urgency of scheduled full-scale studies.

The potential role of foreign collaborators incorporates the inspection of the results of the work, joint discussions, publications and work meetings, as well as the definition of potential technical application. During preparation of the project the meeting with the US collaborators was held and the joint report [30] was presented on the International Congress in Chicago.
