Spanish engineering SME specialized in radiation calculation, located near Madrid offers the use of a software that allows to calculate the 3D activation of an equipment or structure close to a neutron source and the residual dose when the neutron source is off. SEA have been working with CIEMAT on the calculation of activation and dose maps around the beam dump to optimize the design of IFMIF define the proper local shielding device. This knowledge acquired during these developments could be applied in medical or nuclear dismantling applications for prevention and reduction of radiations exposure.
