Description
The invention concerns the facilitation of maintenance for the main-steam pipes of PWRs. The configuration described in the main patent no. 2345580 provides for mounting an isolating valve each within and outside the containment on the main-steam pipe leading out of the containment. It is further proposed to connect a safety valve, whose blow-down pipe terminates outside the containment, in series with the inner isolating valve. The new proposal now places this safety valve in the region outside the containment, but leaves it to be isolated by a valve lying inside. Further details are described. (UWI)

Die Erfindung betrifft die Erleichterung der Wartung von Frischdampfleitungen an DWRs. Die im Hauptpatent 2345580 beschriebene Anordnung sieht vor, an der aus der Sicherheitshuelle herausfuehrenden Frischdampfleitung je eine Absperrarmatur inner- und ausserhalb der Sicherheitshuelle anzubringen, sowie der inneren Absperrarmatur ein Sicherheitsventil vorzuschalten, dessen Abblasleitung ausserhalb der Sicherheitshuelle endet. Der neue Vorschlag verlegt dieses Sicherheitsventil nun in den Berich ausserhalb der Sicherheitshuelle, laesst es aber durch eine innere Armatur absperren. Weitere Einzelheiten sind beschrieben.
