Abstract

The choice of the nuclear reactor coolant substantially defines its engineering shape and safety parameters. Heavy liquid metal coolants (lead, lead-bismuth) are explosion-proof effective coolants. The coolants ensure heat removal at high temperatures and low pressures.
At present, at the national and international levels, new-generation reactor plants with lead and lead-bismuth coolants are being developed on the basis of modern standards of safety, sustainability, economic efficiency, and physical protection. The technical design of the BREST-OD-300 reactor is being completed in Russia, the technical design of the SVBR-100 reactor facility has been completed. At the stage of preliminary engineering is the Chinese reactor with a heavy coolant "CLEAR-I". In Europe, the following reactor plants are being developed:" ALFRED " (European demonstration re-actor with lead coolant of IV generation), MYRRHA (research reactor with lead-bismuth coolant based on electro-nuclear system), ELFR (European commercial reactor with lead coolant of IV generation).
The considerable experience of working in Russia with heavy coolants (reactor installations of submarines, circulation stands) shows that for trouble-free and safe operation of installations with these coolants, it is necessary to execute a complex on technology of the coolant.
