Description
Three reload cores originally planned for the KNK-II reactor were examined at the Karlsruhe Fast Zero Energy Assembly (SNEAK-reactor) under the denomination of SNEAK 11. Two of them were assembled in two versions each: with drawn absorber rods, i.e. corresponding in its criticality with spent power reactors, which is the normal SNEAK assembly; and with absorbers half-inserted as with new cores. The latter of the two in closer to the actual core design task, yet it causes great calculation problems, because they need to be mainly three-dimensional. Main points of the measuring programme included: - critical sizes (with drawn absorbers) or critical insertion depth of the KNK control/scram absorbers, - fission rate distribution, - sodium loss reactivity, - absorption values of control/scram rods and secondary shutdown units.

Abstract (German)
In der Schnellen Nullenergie-Anlage Karlsruhe (SNEAK) wurden unter der Bezeichnung SNEAK 11 drei urspruenglich fuer KNK II vorgesehene Nachladekerne untersucht. Zwei von ihnen wurden in je zwei Versionen aufgebaut: einerseits - wie bei SNEAK-Anordnungen gewohnt - mit gezogenen Absorberstaeben, also in der Kritikalitaet dem abgebrannten Leistungsreaktor entsprechend, andererseits mit etwa bis zur Mitte eingetauchten Absorbern wie beim frischen Kern. Die letztere Version steht der Kernauslegungs-Aufgabe naeher, bietet aber der Berechnung die groesseren Schwierigkeiten, da sie ein wesentlich dreidimensionales Problem darstellt. Das Messprogramm umfasste im wesentlichen: kritische Groesse (bei gezogenen Absorbern) oder kritische Eintauchtiefe der KNK-Regel-Trimm-Absorber, Spaltratenverteilungen, Natriumverlustreaktivitaet, Absorberwerte der Regel-Trimm- und der Zweiabschaltelemente.
