Fragility analysis of prestressed concrete containment under severe accident condition

Finite Element Analysis and simulation of missile impact on Nuclear Reactor Containment Structure

“…Regarding containment structures, researchers have modelled containment structure and other components by FEM models as by Gasch T et al, 2018 and simple conventional models as in Hong and Kang., 2016 and conducted FEA studies to observe deformations, stresses, strains and damage of containment by application of static and dynamic loadings. As mentioned in IAEA standards, the containment structure must be analysed for design pressures and earthquake load also similarly carried by Akbar et al, 1986 and in point of researchers the containments are analysed for failure pressure analysis Yan et al, 2019, where the ultimate potential of containment and critical points such as material strains are identified clearly as presented in Barbat et al, 1998. The fragility nature of materials used in containment varies with respect to internal loading and pressure Jin et al, 2019, and Zhou et al, 2018. And, Shokoohfar and Rahai, 2016 concluded that apart from internal loading temperature does have little amount of impact the ultimate behaviour of containment.…”
