Mechanical Properties of Fuel Cladding Candidate Alloys for Canadian SCWR Concept

An assessment of tensile and creep of five representative candidate fuel cladding alloys for a Canadian Gen IV super-critical water reactor concept was performed based on database development work and complementary experiments including a transmission electron microscopy study of creep in stainless steels. The limiting property would be creep strength of candidate alloys for the “free-standing” fuel cladding design with a hot-spot peak temperature range of 1073–1123 K (800–850°C).
