The features of Candor, a study of a compact high-magnetic field tokamak, based on advanced fuel cycle have been examined from a neutronics viewpoint. Activation behaviour, focusing on the Clearance Index of materials after service in a Deuterium-Helium-3 advanced fuel fusion experiment has been investigated, showing the possibility of being declassified to nonradioactive material (clearance) after their irradiation in the reactor plasma chamber wall, if a sufficient (55-70 y) interim cooling time is allotted. AISI 316L, on the contrary, suffers the presence of Ni, N, Nb and Mo. Concerning pure elements, it is of particular interest the high Clearance Index of Copper and the moderate one of Fe.
