This paper mainly deals with stress field numerical calculations and analysis of the Dual-cooled waste transmutation blanket (DWTB). A comprehensive finite element method (FEM) structure analysis has been performed with the computer code ANSYS5.7. The analysis refers to the steady-state operating condition of an outboard blanket segment. Thermal stresses caused by the temperature gradients in the blanket structure have been calculated. Furthermore, the mechanical loads due to coolant pressure in normal operating conditions have been also taken into account. All the above loads have been combined as input for a FEM stress analysis and the resulting stress distribution has been evaluated. ? 2003 Elsevier B.V.
