DEVICE FOR VVER 1000 STEAM GENERATOR'S WATER AND SURFACE BLOWDOWN SAMPLING

摘要

The purpose of the projected equipment is to achieve the possibility of determining the real local admixture concentrations of the boiler water in operation. This purpose is achieved in a way that a through-socket (2) made on the pressure tank (1) of the steam generator is closed by a bottom (4), provided from its internal side with a carrying pipe (8) to which at least by one grip (9), no less than one pipeline (7) of the water sampling is attached to. At the same time the steam generator axis is situated in the central vertical gap (16) of a tube bundle (12) and the carrying pipe (8) goes through this central vertical gap (16) above the top series level of the tube bundle (12), and between the through-socket (2) and the bottom (4), a T-piece (3) is inserted to a branch of which a blow-down pipeline (6) is connected. The equipment is applicable primarily in the field of the nuclear energy industry.IMAGE
