description: Subject matter of final qualification work: "Development of installation of automatic etching of welded seam of upper path of technological channel of RBMK reactor". The work is devoted to improvement of technology of carrying out activities on RBMK-type reactor performance restoration with respect to preparation of technological channels for diagnostics and repair. Tasks solved in the course of research: - To study the object where the operation of weld location - RBMK reactor, its core, technological channel, conditions and regulatory requirements of measures to restore the reactor's characteristics are carried out. - To study methodology of electrochemical treatment process, peculiarities of its course applicable to austenitic steel alloys. - To develop technical requirements, calculate characteristics, describe possible compositions of electrolytes, offer a set of technical solutions for further experimental and design works.In the process of research, the employees of Kursk, Leningrad and Smolensk NPPs directly involved in measures for reactor performance restoration were interviewed, the initial data and calculations of current characteristics of the plant were analysed, and the conclusion about the possibility of its development and about the effectiveness of implementation was made.
