| Popis: | This paper presents the results of calculations of fast neutron flux and displacement damage expressed as displacements per atom (dpa) number in stainless steel components of homogeneous steel-water shields. The changes of relations between the fast neutron flux and dpa number, which is a spectrum dependent parameter that amongst others serves as a design criterion of a fusion reactor project, versus the distance from the first wall are obtained for different water fractions in steel-water shields. A simplified analytical method to estimate the displacement damage in metal components of a fusion reactor is proposed. This method is expected to be used for simple and quick estimation of the displacement damage in metal components of a fusion reactor, for example the copper stabilizer of toroidal field coils and construction steel components of first walls, blankets etc. |
