Overview of recent advancements in IFMIF-DONES neutronics activities.

Abstract

Recent advancements in the neutronics activities of the IFMIF-DONES project, developed within the EUROfusion framework, are presented. These include updates to radiation dose maps during commissioning and normal operation of the accelerator systems; material irradiation analyses and shielding optimization of the test systems; activation inventories of 7Be, 3H, and activated corrosion products in the Li systems; shutdown dose analyses of transportation and storage of radioactive waste, cooling water and atmosphere gas activations, skyshine to the public, etc. The development of simulation tools, nuclear data evaluation, and nuclear experiments for the specific needs of DONES neutronics are highlighted, as well as the nuclear analysis handbook and database. Several challenges for future development are also discussed to ensure the provision of high-quality nuclear analyses.
