Fusion - FUSION Technologies and Materials

The topic covers the full range of technology and materials developments for fusion reactor systems, ranging from devices in operation (e.g. Wendelstein 7-X) or under construction (JT-60SA, ITER) to the preparation of DEMO and a fusion power plant. Approaching a fusion power plant, the technology requirements become increasingly complex. Existing systems have to be advanced to meet reactor requirements or even new systems have to be developed (e.g. test blankets for ITER).
