Abstract

Three-dimensional neutronic, activation and residual decay heat calculations have been performed for the ITER device. Particular attention has been paid to the 3D geometrical modelling of the device and in particular its divertor. The fusion relevant calculational capabilities of the Monte Carlo code TRIPOLI have been satisfactorily put to use and the results demonstrate clearly their value: versatile three-dimensional modelling; probability table treatment; thermalisation treatment; standard deviation procurement.
An integrated interface allows the coupling of the Monte Carlo results with the inventory code FISPACT. This combination allows three-dimensional activation and residual decay heat calculations, and lead to a reliable assessment of any activation response function. The inventory code FISPACT allows the uncertainties arising from the uncertainly on the activation cross-sections to be quantified for both specific and integral results.
This integrated TRIPOLI - FISPACT calculational scheme has been applied to the determination of activation and decay heat values in a detailed three-dimensional model of the ITER divertor. The exposure scenario employed is appropriate for the Basic Performance Phase of ITER operation. Separate calculations were performed for the three alternatives for protective coating material: tungsten, beryllium and carbon. .
