Abstract
The electron cyclotron (EC) system is critical for heating and controlling the fusion plasma. The system foreseen for installation in the equatorial port of the EU-DEMO reactor will be exposed to intense neutron irradiation, making activation, maintenance, and waste classification key design constraints. This study analyses the neutronic response and activation of the main EC components using MCNP to calculate neutron fluxes, energy spectra, and nuclear heating. It also includes FISPACT-II calculations of activation inventories, decay heat, contact dose rates, and dominant radionuclides. The results, assessed over relevant cooling times, show that stainless-steel components located closest to the plasma exceed low-level waste (LLW) limits even after extended cooling periods, whereas inner and rear components exposed to lower neutron fluxes generally meet LLW criteria. Dominant long-lived radionuclides have been identified to support waste classification and disposal planning. These findings provide essential guidance on material selection, waste minimisation, shielding and cooling design, and interim storage strategies, supporting the safe integration of the EC system within the DEMO reactor.
