Research and development on prestressed concrete reactor vessel (PCRV) analysis is summarized. Discretization problems were investigated for the finite element idealization of PCRV in addition to questions with regard to long term creep and concrete failure in the ultimate load regime. Special attention was given to the triaxial load conditions in massive structures and the specific concrete properties under hygrothermal environments. The finite element system SMART was programmed for the analysis of prestressed concrete reactor vessels. It consists of two parts: SMART I - Statics; SMART II - Diffusion. SMART serves both to static analysis of stresses and deformations and the computation of hygrothermal boundary conditions in massive structures within a compatible software package.
