Abstract

The paper presents an assessment aimed to point out the impact of the neutron spectra and the activation libraries on the relevant tungsten activation characteristics (the specific activity and the decay heat). The analyses refer to the ITER divertor dome and they are based on the ITER Basic Performance Phase. The dome protective material is a 10 mm thick tungsten layer, the heat sink is Glidcop (water cooled). The dome support and the cassette body are in AISI 316LN (water cooled). The integrated radiation transport and activation methodological approach Vitamin-Scale-Anita has been applied, that includes the self-shielding treatment
