Abstract
Plasma diagnostics and reactor control systems in future fusion power plants, such as DEMO, will rely on optical windows to monitor key plasma characteristics under intense irradiation conditions. Selecting suitable window and coating materials such as quartz, fused silica, sapphire, HfO2, and MgF2 is therefore critical to ensuring component reliability and safety. This study investigates these candidate materials’ activation calculations in the DEMO environment. Using the MCNP code, neutron spectra have been calculated at window-relevant locations in the outboard equatorial port and upper port limiters, considering both helium-cooled pebble bed and water-cooled lithium lead breeding blankets. Activation analyses have been subsequently performed with the FISPACT-II inventory code to evaluate the activity, decay heat, contact dose rates, and dominant contributing nuclides under the initial DEMO irradiation scenario. The results provide insights into neutron irradiation effects relevant to the activation performance of window materials and coatings, and contribute valuable input to component design and safety evaluations within the EUROfusion Safety & Environment Work Package framework.
