Radioactive waste and restoration of contaminated territories in the CIS countries

The European Commission, DG XI, has published an invitation to tender for studies on radioactive waste management and restoration of contaminated territories in the countries of the Commonwealth of Independent States (CIS).

The studies concern the analysis of a number of key issues concerning nuclear safety in the CIS countries, with a view to enabling the Commission to identify potential themes for future technical assistance projects in the field of radioactive waste management and restoration of contaminated territories.

The study contracts to be concluded concern the following:

- Ref: XI/C-3/1166: Analysis of the medium- and long-term environmental consequences of the migration of radionuclides from the Karachay Lake in the southern Urals (Russian Federation). Determination of the radiological impact to the population including those still living downstream along the Techa river (assessment of possible counter measures which could be implemented);
- Ref: XI/C-3/1167: Feasibility study for an underground repository for long-lived non-heat-generating radioactive waste in the Ukraine (catalogue of possible sites like salt or dry ore mines, assessment of suitability, ranking of sites in terms of radiological impact to population, access routes, acceptance by population, assessment of migration pathways, radiological impact calculations, drafting of elements of a safety report);
- Ref: XI/C-3/1168: Analysis of the radiological impact on the population of the Balapan region of Kazakhstan as a result of radionuclides from nuclear test explosions via the drinking water exposure pathway (hydro-geological situation, migration of radionuclides with groundwater, modelling of flow, possible future radiological exposure, definition of an experimental programme, possible counter measures);
- Ref: XI/C-3/1169: Evaluation of the suitability of the sites and facilities at "Degelen" and "Azgir" in the Republic of Kazakhstan as a final repository for radioactive waste (collection of available environmental and geological data, waste streams to be expected, calculation of "radiological" consequences, expert advice on suitability);
- Ref: XI/C-3/1170: Evolution of the radiological situation around nuclear reactors with spent fuel enclosed, which are dumped in the Kara Sea (assessment of radionuclide inventories of the two reactors with spent fuel of the Abrasimov Fjord and one reactor within the sunken submarine in the Stepovogo Fjord, best possible determination of the containment situation, analysis of corrosion and of probable release rates to the surrounding water and sediments, calculation of possible radiological consequences to man);
- Ref: XI/C-3/1171: Input to remediation strategies for the restoration of contaminated territories resulting from the Chernobyl accident aiming to assess the respective merits of a number of management options (including the one consisting of doing nothing) based on economic and radiological criteria. Remediation actions will deal with agricultural lands and forests, and include the possible implementation of large-scale decontamination techniques, or change of agricultural practices. The scope of the study will cover the contaminated territories around Chernobyl giving rise to extra doses to the population higher than 1 m Sv/a, and is intended in particular to take advantage of Russian experience in land remediation.
