Description

Automatic translation: Since the spring of 1969, the AVR has been exchanged for graphite elements continuously pressed fuel elements made of A3 material are added. To date (May 1973) in the AVR core, in addition to the Elements of the first load (UCC elements) altogether 65000 pressed fuel elements (45000 carbidic, 20000 oxidic fuel elements) accumulated, the oldest in now about 1200 full load days a burnup of 15% fima and a fast neutron dose of 2.4 x 1021 cm-2 (E > 0.1 MeV).

Abstract (German)

Seit Frühjahr 1969 wurden dem AVR im Austausch gegen Graphitelemente laufend gepreßte Brennelemente aus A3-Material zugegeben. Bis heute (Mai 1973) haben sich im AVR-Core neben den Elementen der Erstbeladung (UCC-Elemente)insgesamt 65000 gepreßte Brennelemente (45000 karbidische, 20000 oxydische Brennelemente) angesammelt, deren älteste in jetzt ca. 1200 Vollasttagen einen Abbrand von 15 % fima und eine schnelle Neutronendosis von 2,4 x 1021 cm-2 (E > 0,1 MeV) erreicht haben.
