b'In situ strain measurements of Cr coated and uncoated Zircaloy-4 during simulated LOCA testing showed that creep and plasticity related deformation mechanisms can be quantified to support accelerated materials qualification for light water reactors.Figure 2.

LOCA tests were from digital image correlation data,cladding tubes were prepared forperformed at a temperature ramp showcasing a change in deformation mechanism around 2%/s strain rate this work and were tested at ORNLsrate of 5C/s, with varied internal SATS.
