Abstract [en]

Activation inventories, decay heat, contact dose rate and radiation induced damage are important nuclear quantities which need to be assessed on a reliable basis for the safe operation of a fusion nuclear power reactor and its decommissioning. This paper describes the calculations performed in the frame of the EUROfusion JETS programme of the activation and dose rate of materials irradiated in the Inner/Outer Long Term Irradiation Station ((I-O)LTIS) during DD and DTE2 campaigns. In the frame of JET3, samples of real ITER materials used in the manufacturing of several different, mainly in-vessel and vessel, components will be irradiated at JET during DTE2 such as ITER-grade W, Be, CuCrZr,316L(N), and also functional materials used in diagnostics and heating systems for radiation damage studies. Neutron induced activities and contact dose rates at shutdown are calculated by means of the FISPACT code using the irradiation scenario specified for JET, with the neutron flux densities and spectra provided by the preceding MCNP neutron transport calculation for (I-O)LTIS box.
