Being a critical element of the nuclear power plant, it is imperative that the containment structure must be designed optimally. In this paper, the effect of steel liner on concrete containment structure was studied by Finite Element Method (FEM) in ABAQUS software. For doing so, containment structure was modeled by taking the dimensions from previous research work [Jiachuan Yana,2018] which are used in third generation power plant and was subjected to LOCA (Loss of Coolant Accident) pressure. To study the effect of thickness of steel liners, the magnitude of the principal stress at critical nodes in concrete containment structure without steel liner was compared with steel liners in the concrete containment structure. 15 different models were developed by varying the thickness of the steel liner to study the behavior of principal stresses. Upon doing the analysis, it was found Maximum principal stresses in tension reduce 1.778% & Maximum principal stresses in compression reduce 5.911% by adding 5mm steel liner to structure on the inner most edge of the structure.
