Following the Fukushima-Daiichi incident, there has been considerable interest in developing accident-tolerant fuel cladding materials to make light water reactors (LWRs) safer. Zircaloys are used as the fuel cladding materials in the current LWRs. Under off-normal conditions such as loss-of-coolant accidents (LOCA), exothermic reactions of Zr with steam can lead to severe consequences. In this study, an aluminum-bearing ferritic steel (e.g. Kanthal APMT steel) is investigated to evaluate its feasibility for accident-tolerant fuel cladding applications for an advanced LWR (I2S-LWR) concept under development. Tensile properties of the steel are compared with those of Zircaloys and other steels. Presence of serrations in stress-strain curves of APMT steel under certain test conditions revealed the occurrence of dynamic strain aging. Microstructural characteristics of the deformed specimens are examined by scanning and transmission electron microscopy. The work is supported by the DOE Office of Nuclear Energy’s Nuclear Energy University Programs (NEUP).
