Abstract
1414179 Degassing and reducing the radioactivity of turbine condensate KRAFTWERK UNION AG 22 Dec 1972 [24 Dec 1971] 59539/72 Heading B1M A method of degasifying and reducing the radioactive content of condensate from a steam turbine in a nuclear power plant having a boiling water reactor arranged to generate steam to drive the turbine, a condenser for condensing exhaust steam from the turbine to form a main condensate, and at least one feed water preheater which is heated by steam which is bled from the turbine and which condenses to form a secondary condensate comprises feeding the secondary condensate into an expansion vessel, introducing the thus expanded secondary condensate into the main condensate from the condenser so as to evaporate and thereby degas the main condensate, the expanded secondary condensate being at a higher pressure and temperature than the main condensate, and conducting the degassed condensate along a flow path to reduce its radioactivity. Fig. 3 shows a degassing apparatus where the secondary condensate from the expansion vessel passes via throttling elements to pipes 11-14 where the condensate passes through apertures 30 in the lower part of the pipe into the main condensate in channels 15-18 and evaporates, and thus degasses the main condensate, which then flows to a baffled sinuous path (Fig. 5, not shown) in the lower part of the apparatus to allow its radioactivity to decay.
