Influence of irradiation on KISCC of Zr–1%Nb claddings
Source abstract
Abstract
Abstract Experimental results on iodine induced stress corrosion cracking (SCC) in irradiated claddings from Zr–1%Nb alloy are analyzed. Fatigue cracks were grown at their inner surfaces. The irradiation was carried on in the liquid sodium cooled BOR-60 to the fluence not lower than 10 22 n/cm 2 . The SCC-test was carried at 350°C, in argon gas at constant pressure and iodine surface concentration of 0.2 mg/cm 2 . The threshold stress intensity factor for the irradiated Zr–1%Nb claddings was determined to be ∼2.0 MPa√m.
