[en] The efficiency of measures realized in order to eliminate the Chernobyl' accident effects is estimated. The principles of organization of the emergency-engineering service for accident elimination in nuclear power engineering are described. The automated information safety system should from the technical basis for this service. The information system structure is determined. The list of main directions of research and design works realized in the emergency-engineering service interests is given. It is noted that all parts of the emergency-engineering service must prepare the plants of works together with the USSR civil defense service, and they should interact in the process of accident elimination basing on coordinated organizational and technical solutions
