Abstract
Before starting with the construction of the International Fusion Materials Irradiation Facility, the objective of the Engineering Validation and Engineering Design Activities (EVEDA) phase wil be to demonstratefeasibility of design. For this EVEDA prototype, analysis of the dose rate evolution during the beam-off phase is necessary for radioprotection and maintenance feasibility purposes. The key pointsfor determining the dose rates of the beam-off phase are on one hand the neutron source produced along the accelerator beam line and on the other hand the deuteron losses giving rise to this neutron source. A new methodology to compute the neutron source coming from the deuteron interactions with the intercepting material as well as with the deuterium previously implanted has been developed. This new procedure consists of evaluation of the low-energy deuteron-induced neutron source that is not calculated by most transport codes and assessment of the dçuterium concentration evolution in the material, which is generally not taken into account in this type of calculation. The impact of this new approach on the neutron source and dose rate results is very relevant.
