Cladding Failure Modelling for Lead-Based Fast Reactors: A Review and Prospects

Lead-cooled fast reactors (LFRs) are considered one of the most promising technologies to meet requirements introduced for advanced nuclear systems. LFRs have higher neutron doses, temperatures, burnup and an extremely corrosive environment. The failure studies claddings play a vital role in improving safety criteria promoting research on materials. This paper presented comprehensive review extreme environment based fuel performance analyses transient reference LFRs. It provided clear image cladding failure, focusing underlying mechanisms, such as creep, rupture, fatigue, swelling, corrosion, etc., which resulted from motions defects, development microcracks accumulation fission products some extent. Some fundamental parameters behavior models Ferritic/Martensitic (F/M) steels Austenitic stainless (AuS) were summarized this paper. A guideline modelling was also bridge gap between material realistic demands application
