Structural analysis and design against failure of fusion power plant components with special reference to pulsed operation

This study presents the theory of structural analysis and design code rules and constraints as applied to predict lifetime and prevent failure of components and is tailored to deal with the specific design requirements of fusion components. Example calculations are performed for a proposed ITER-like first wall using finite element analysis codes and an assessment of the structural behaviour is also included. The results of the calculations are used to arrive at a proposed design methodology, which accounts for the structural mechanisms likely to occur when operating a tokamak in pulsed mode, as proposed for ITER.
