- <p>In IFMIF-DONES, a deuteron beam will impact on a flowing liquid lithium target, resulting in an intense neutron source. Other radiation sources will also arise due to the interactions between deuterons and the beam facing accelerator components. These radiation fields may cause some negative effects, such as damage to equipment or the generation of residual radiation sources. The characterization and mitigation of all the radiation sources are crucial for a safe operation and maintenance of the facility. In this study, the optimization and/or implementation of some radiation shields located in critical areas is considered to reduce the doses during operation and shutdown. Three scenarios are assessed: i) shielding optimization of the High-Power Beam Dump for the accelerator commissioning, ii) shielding optimization for the scraper of the High Energy Beam Transport line and the Fast Safety Isolation Valves, and iii) shielding implementation to reduce the radiation transmission through HVAC wall penetrations. Radiation maps of the biological dose and the dose to silicon are computed, showing the impact of such shielding elements.</p>
