Demand for energy is increasing day by day across the world resulting in construction of more number of atomic power stations. Critical facilities such as nuclear containment structure design require an exact and accurate assessment of aging requirements, because any failure of these facilities causes great threat to society. In the present study nuclear containment structure is modelled according to specification of kudankulam nuclear containment structure, static and dynamic analysis is carried out for the same site location. In order to overcome the failure of much nuclear containment structure due to adverse durability effects before their expected design life, long term analysis of nuclear containment structure is carried out by considering geometric non-linearity, material non-linearity and temperature effects for period of 100 years using relevant standard codes. The results obtained in this study shows that the long term deflection by considering the effects of creep, shrinkage and temperature are within permissible limit according to clause of I.S 456 2000 is evaluated for period of 100 years.
