Abstract
The forthcoming deuterium–tritium (DT) campaign at the Joint European Torus (JET) will induce a sig-nificant activation of the system components. In the present work we evaluate the temporal evolutionof the radioactive species in the main in-vessel components after the end of the future DT campaign,assuming different levels of neutron irradiation. The neutron flux in the selected components is calcu-lated by the MCNP5 code using the emission source by a typical DT plasma. The resulting neutron spectraare then input to the FISPACT code that computes the evolution of the radioactive species generated bythe neutron activation process. For each irradiation scenario, the time behavior of the contact dose rateis determined.
