(a) Dislocation density (first bars, red) and M parameter values (second bars, blue) in a Zircaloy-2 alloy proton-irradiated to 2.3 dpa at 280, 350 and 450°C. The very first two bars on the far left of the figure correspond to the non-irradiated (NI) material. (b) Ratios of the CMWP- and TEM-determined dislocation densities, ρX-ray/ρTEM, of the same specimens as in (a) plotted versus temperature. TEM data were taken from Topping et al. (2019BB84). (c) Dislocation densities (first bars, red) and M parameter values (second bars, blue) in neutron-irradiated Zircaloy-2 specimens plotted versus neutron fluence. The vertical dashed line separates the cladding and channel material data. (d) Ratios of the CMWP- and TEM-determined dislocation densities, ρX-ray/ρTEM, of the same specimens as in panel (c) plotted versus neutron fluence. TEM data were taken from Harte et al. (2017BB37).
