Radiation damage to first wall in fusion reactors

Fusion energy is shown as a part of the solution to the increasing energy demand and also as a production and climate-friendly way due to the negative impact and limitation of fossil fuels on climate change. Fusion can provide an almost unlimited amount of energy, can be virtually unlimited in fuel sources, and no fission-like content is formed as radioactive waste, but reactors have yet to produce a positive net energy output. Building a functional fusion reactor is grueling, but many important research projects are underway. Research on technical configurations and plasma physics is still ongoing, making it difficult to find a precise timeframe for fusion energy. Tokamaks and Stellarators are major reactor models for fusion. Both reactors have advantages and disadvantages. Therefore, in this thesis, in an ITER fusion reactor, the interaction states of the radiation in certain energy ranges, which are used in the first wall structure and that affect the materials with a high density of iron element, with the help of SRIM/TRIM, total displacements, ionization, ion gaps, vibrations, etc. diagrams were analyzed.
