b'Figure 1. Boiling Transition (Dryout) Testing of FeCrAl Cladding (a) Temperature and hoop stress profile of Zircaloy-2 cladding during 300-650C temperature cycling at 55 MPa bursting at 4 cycles. (b) Temperature and hoop stress profile of C26M cladding during (a) (b) identical thermal cycling at a higher hoop stress. C26M did not burst after 54 cycles, at which point cycling was concluded.Figure 2. Boiling Transition (Dryout) Testing of FeCrAl. Dry out hoop stress map obtained by combining failure criteria from C26M burst at 55 and 58 MPa hoop stress cycled at 300-700C and 300C-800C, respectively, and Zircaloy-2 burst at 42 and 47 MPa hoop stress, cycled at 300-650C. The Xs indicate when cladding failure occurred; the left most X indicate single cycle cladding failure.2020|AFC ACCOMPLISHMENTS 99'
