The main objective of this study was to provide a comparison between the two origins of defects: pre-existing ones and neutron-induced defects. The interest was to explore, which is a dominating type of defects in terms of im- posing effect on plasma species. At first it was found, that energetically both types have the same effect on plasma species. Secondly it was found, that the spatial range of interaction between lattice defects and plasma components is not determined by the origin of a defect. Distinct defects would rather couple themselves to defects of other origin in terms of the interaction range: GB with vacancy cluster, edge dislocation with SIA cluster. And the last conclusion was to determine, whether there is any distinction between H and He in terms of the interaction with lattice defects. Generally, H and He behave in a similar manner, however, there was one distinct occasion, where a substantial difference was observed in interaction patterns in the case of dislocation loops.
