Abstract

Die erfindungsgemässe Einlassmischer-Halterung (30) für einen Strahlpumpeneinspannaufbau eines Siedewasserreaktors umfasst ein Halteband (40) mit Anbringungsblöcken(32, 34) und eine Einspannklammer (12). Das Halteband (40) wird durch die Mischerhalterungs-Anbringungsblöcke (32, 34), die direkt an der Einspannklammer (12) angebracht werden können und das Halteband (40) an der Einspannklammer (12) fixieren, an seiner Stelle gehalten. Durch das Befestigen des Haltebands (40) an der Einspannklammer (12) stellt das Halteband einen einstellbaren Kontaktpunkt zwischen der Einspannklammer (12) und dem Einlassmischer (2) bereit, wodurch der Einlassmischer (2) auch dann stabilisiert wird, falls die herkömmlichen Stellschrauben an der Einspannklammer (12) versagen. Daher wird die Einlassmischer-Position selbst dann aufrecht gehalten, wenn sich die Stellschrauben aus ihrer Position bewegen. Zudem wird die Abtrennung und/oder die teure und zeitaufwändige Reparatur der Stellschrauben, falls die Stellschrauben versagen sollten oder anderweitig eine Wartung erfordern, verhindert. Weiter betrifft die Erfindung ein Verfahren zum Anbringen der Einlassmischer-Halterung.
