Criticality calculation for the Jupiter fluidized bed reactor

Creators

Description

Automatic translation: Fuel elements of gas-cooled high-temperature reactors consist of spherical or prismatic graphite bodies in which PyC-coated oxidic or carbidic fuel particles ((TH,U)O2 or (TH,U)C2) are embedded. If unused fissile and fertile material is to be recovered from irradiated fuel elements of this type, the graphite must be separated off in a preparatory process step. Only then can the heavy metal be dissolved using a suitable reagent.

Abstract (German)

Brennelemente gasgekühlter Hochtemperaturreaktoren bestehen aus kugelförmigen oder prismatischen Graphitkörpern, in die PyC beschichtete oxidische oder carbidische Brennstoffpartikel ((TH,U)O2 bzw. (TH, U)C2) eingebettet sind. Soll aus bestrahlten Brennelementen dieses Typs unverbrauchter Spalt- und Brutstoff zurückgewonnen werden, muß in einer vorbereitenden Verfahrensstufe der Graphit abgetrennt werden. Erst dann läßt sich der Schwermetalleinsatz durch ein geeignetes Reagens in Lösung bringen.
