FIELD: nuclear engineering; water-moderated water-cooled reactor plants using steam pressurizer system.
SUBSTANCE: proposed steam pressurizer that incorporates provision for maintaining desired water-gas and chemistry conditions of primary circuit coolant has housing accommodating heaters, cooling sprayer, and shell. Heaters are disposed in pressurizer water space and cooling sprayer, in steam space. Inner space of shell communicates on top with steam space and at bottom, with water space of pressurizer; inner space of shell also houses additional sprayer installed in its top part and made in the form of conical funnel; top part of shell is congruent with sprayer configuration.
EFFECT: enhanced reliability of pressurizer system.
