Description

In the course of the irradiation of a 16-rod prototype bundle, the basis has been established for the irradiation of experimental fuel assemblies containing full-length PWR fuel rods in standard positions of the MZFR. The prototype bundle was discharged after an irradiation time of 284 full power days and a burnup of 11400 MWd/tU. The overall performance of the prototype bundle was highly satisfactory. Detailed post-irradiation examinations confirmed the good conditions of bundle structures and fuel rods. (orig.)

Abstract (German)

Mit dem 16-Stab Prototypbuendel wurden erstmals die Grundlagen fuer die Bestrahlung eines Versuchsbrennelements mit Original-DWR-Brennstaeben auf einer Normalposition im MZFR erarbeitet. Das Prototypbuendel wurde nach einer Bestrahlungszeit von 284 Volllasttagen und einem Abbrand von 11400 MWd/tU entladen. Das Betriebsverhalten des Prototypbuendels kann sehr positiv beurteilt werden. Detaillierte Nachbestrahlungsuntersuchungen in den Heissen Zellen bestaetigten die einwandfreie Beschaffenheit der Buendelstruktur und der Brennstaebe. (orig.)
