To develop and to assess the suitability of a material for use as the first structural wall in a fusion reactor, it is necessary to know the transmutation behaviour of the material. In the present paper we propose a transmutation calculational strategy and how this methodology is implemented in a computer code package, called CIBELES. The code system has been developed to calculate and especially to analyze the transmutations resulting from neutron irradiation. The system includes powerful computing methods for analysing the results, and uses the numerical calculation techniques of the ORIGEN code. The transmutation characteristics of two structural materials, AISI 316L austenitic steel and DIN 1.4914 martensitic steel have been evaluated for the peripheral target position in the High Flux Isotope Reactor (HFIR), and the first wall position of the Culham Conceptual Tokamak Reactor MarkIIA (CCTRII).
