In terms of safety, nuclear fuel cladding is one of the main barriers in preventing the release of radioactive materials to the environment.The integrity of the fuel cladding is essential both in operation and in the long-term storage of spent nuclear fuel, not to mention accident conditions.In this paper, we review shortlyrelevantaccident tolerant cladding materialsfrom the Finnish point of view. Features compared to the traditional Zr-alloy cladding in the areasof oxidation, hydrogen pick-up,mechanical behaviourand fuel performance modellingare considered.
