摘要

Ensuring of safety and reducing of ecological hazard during dismantlement of nuclear-powered submarines present one of the most urgent issues. In the course of repairing and dismantling a large number of demountable equipment built in nuclear-powered plants that have been operated for a long time under the conditions of elevated temperatures, corrosive impact of working medium, high density of neutron flux, and being contaminated, is produced. The above equipment is manufactured, mainly, of expensive high-alloy stainless steels, titanium and copper alloys, and other valuable materials. Traditional methods of decontamination such as vacuum machining, sandblasting, etc., based on mechanical removal of contaminants, treatment of surfaces with water or organic solvents, as well as methods based on physical-and-chemical processes, possess a number of shortcomings. The application thereof leads to production of a large amount of liquid radioactive waste, to a significant increase of pollution hazard for the environment, besides, requires use of expensive materials and, in some cases, toxic agents.
