Turbine condenser for use in nuclear power plant

Abstract

Abstract PURPOSE:To simplify the regular cleaning operation of the atomic power plant by constructing a hot well part by partitioning the bottom part of the condenser by a ceiling plate, making a zigzag-shaped passage by a partition plate whose front and rear parts are alternately cut away and forming the bottom part of the passage into a semicylindrical shape. CONSTITUTION:The ceiling plate 5 is extended at a suitable height from the bottom plate 3 of the condenser 1 and a zigzag passage is made by a partition plate 8 whose side and parts are alternately cut away, within a hot well at the lower part of the hot well and an opening 6 through which a condensate is caused to flow down at both front and rear ends of the central part of the ceiling plate 5, is provided. An outlet pipe 7 is connected to the terminal end part of the front end central part through a screen 10, and the passage of each row is covered with the semicylindrical bottom surface 11 except front and rear end parts, that is, a hot well corner 15 the opening 6 and the screen 10, and spaces between both ends of the bottom surface 11 are blocked by a blocking plate 14. By this arrangement, corrosive products within the condensate are accumulated on the bottom surface 11 and the hot well corner 15 while passing through the hot well 4, and hence cleaning is facilitated.
