Emergency scram actuation device for nuclear reactors
Description
The safety parameter employed for emergency scrams of a liquid metal cooled reactor is the coolant pressure. An actuation bellows is provided which is connected to a measuring chamber by means of a flow system. Both units are installed in a coolant flow section. The measuring chamber proper is connected with the coolant by means of an aperture limiting the flow. Inside the measuring chamber there is an expansion space filled with gas. Pressure changes in the coolant affect the pressure in the expansion space. Expansion of the bellows actuates the release mechanism. (DG)

Der Sicherheitsparameter fuer die Notabschaltung des fluessigmetallgekuehlten Reaktors ist der Kuehlmitteldruck. Es ist ein Betaetigungsfaltenbalg vorgesehen, der mit einer Messkammer in Durchflussverbindung steht. Beide sind in einer Kuehlmittelstroemungsstrecke angeordnet. Die Messkammer selbst steht ueber eine den Durchfluss begrenzende Oeffnung mit dem Kuehlmittel in Verbindung. Innerhalb der Messkammer befindet sich ein Expansionsraum, der mit Gas gefuellt ist. Die Druckaenderungen im Kuehlmittel wirken sich auf den Druck im Expansionsraum aus. Die Faltenbalgexpansion betaetigt den Ausloesemechanismus. (DG)Files
