Description
Increased friction of the drives of the first shut-down system of the reactor KNK II has been observed since 1986. A further increase of friction occurred in both of the two shut-down systems, which caused a blockage of one absorber within the second shut-down system in 1988. However, the capability of both systems to shut down the reactor was not affected at any time. The results of subsequent examinations are presented. Conclusions are drawn for future designs. (orig.)
Abstract (German)
In der Anlage KNK II wurden seit 1986 erhoehte Reibungswerte am Erstabschaltsystem festgestellt. Weitere erhoehte Reibungswerte wurden 1988 an beiden Abschaltsystemen beobachtet; dabei kam es zu einer Blockierung an einem Abschaltstab des Zweitabschaltsystems. Die sichere Abschaltung des Reaktors mit beiden Systemen war jedoch zu keiner Zeit beeintraechtigt. Die Ergebnisse nachfolgender Untersuchungen werden beschrieben. Konsequenzen fuer zukuenftige Konstruktionen werden abgeleitet. (orig.)Additional details
