ABSTRACT: Integrated reactor structural
design makes the pressure vessel itself and loads more complicated, so stress concentration
makes strength failure easier at reactor coolant pump nozzle. The general purpose
finite element program ANSYS/ WORKBENCH was used for 3D stress and fatigue analysis and
the results of the evaluation are based on RCC-M criteria. The integrated reactor
structural design is evaluated to demonstrate with applicable criteria and ANSYS/WORK- BENCH has better operability
than ANSYS APDL on stress analysis of reactor pressure vessel.
