Description

Calculations of the displacement per atom have been performed for an amorphous metal Fe40Ni40B20, which has been exposed to incore reactor irradiation. Up to 99% of the radiation induced displacements result from the nuclear reaction 10B(n,α)7Li + 2.79 MeV, which is initiated by thermal neutrons. The number of primary knock-on atoms generated by α- and Li-particles and the size of cascades have also been calculated. A fluence of thermal neutrons of 1 x 1019 nsub(th)/cm2 is found to produce a damage in amorphous Fe40Ni40B20 which corresponds to 0.65 dpa. (orig.)

Abstract (German)

Fuer amorphe Metalle der Zusammensetzung Fe40Ni40B20, die im Inneren eines Reaktorkerns mit Neutronen bestrahlt wurden, werden dpa-Berechnungen durchgefuehrt. Die strahlungsinduzierten Atomverlagerungen ruehren in 99% aller Faelle von den Folgeprodukten der durch thermische Neutronen initiierten Kernreaktion 10B(n,α)7Li + 2,79 MeV her. Sowohl die Anzahl der durch die α- und Li-Teilchen erzeugten Primaeren Rueckstossatome als auch die Kaskadengroessen werden bei der vorliegenden Berechnung ermittelt. Fuer eine Fluenz thermischer Neutronen von 1 x 1019nsub(th)/cm2 ergibt sich in amorphem Fe40Ni40B20 eine Schaedigung von 0,65 dpa. (orig.)
