Beam Dump of SPIRAL2 Facility: Residual Dose Rate Calculations and Impact of the Computational Approaches

The SPIRAL2 facility will produce 5 mA of deuterons at 40 MeV. The work presented here focuses on predicting the residual dose rates that can be expected in the beam dump room of this facility during beam-off phases as consequence of the deuteron stopping. The effect of different transport and activation computational approaches on the dose rates calculations is assessed.
