FIELD: nuclear power engineering; water- cooled power reactors. SUBSTANCE: additional intermediate header is installed at bending point of hairpin tubes on heat-transfer surface; outlet ends of hot branches and inlet ends of cold ones of part of peripheral tubes are secured in this header; in addition intermediate header is connected to gas exhaust system that functions to remove gas from upper points of hairpin heat-transfer tubes of vertical steam generator. EFFECT: enhanced safety of nuclear power plant. 2 dwg
