Aid was provided by the Americans and the European Union by implementing a number of financial instruments, including TACIS (Technical Assistance Program for the Commonwealth of Independent States) and, subsequently, ENPI (European Neighborhood and Partnership Instrument).
The main thrust of the funding was to support radioactive waste disposal and neutralize the environmental threat. To this end, support was provided, among other things, for the construction of an advanced waste repository, which allowed the Mayak Combine to be transformed into a center for processing radioactive waste, but also for the production of commercial radioactive isotopes for medicine and industry.
