Device for decay heat removal in a steam power plant heated by nuclear power
Description
The device is designed to remove the afterheat of a e.g. gas-cooled reactor if the steam turbine of the steam power plant including a water-steam separating vessel is shut down. For this purpose already existing components are used to a large extent. E.g. a heat exchanger, which may be cooled externally, is connected to the outlet for the condensed water of a start-up flash tank of the plant. It is also possible to use the heat exchanger as a preheater, whose connections for the turbine steam may selectively be connected to coolant pipes. (DG)

Die Einrichtung dient der Nachwaermeabfuhr eines z.B. gasgekuehlten Reaktors, wenn die Dampfturbine der Dampfkraftanlage mit Wasser-Dampf-Trenngefaess abgeschaltet wird. Hierzu werden weitgehend bereits vorhandene Anlagenteile verwendet. So ist z.B. ein von aussen kuehlbarer Waermetauscher in die Ausgangsleitung fuer das Kondenswasser eines Anfahrentspanners der Anlage eingeschaltet. Es ist auch moeglich, den Waermetauscher als Vorwaermer zu benutzen, dessen Anschluesse fuer den Turbinendampf wahlweise an Kuehlleitungen anschliessbar sind. (DG)Files
