Activation characteristics of reactor components are essential for the safety design and environmental assessment of a near-term deuterium-tritium (D-T) Experimental Reactor (ITER). The inventory of neutron induced activation products can be significantly influenced by the operational scenario. However, the degree of impact on the reactor components depends on the various safety related quantities. In general, the quantities relevant to reactor safety, such as decay heat, early dose, and chronic dose, have higher dependence on the operational scenario and favor a lower duty cycle. The waste management related quantities such as waste disposal rating and biological dose rate, however, are not very sensitive to the operational scenario, and depend rather on the total neutron fluence. In this paper the authors report the results of analysis for a 316SS/water shielding blanket and a V-alloy/lithium advanced blanket based on the pulsed operational scenario. For both blankets, a water cooled, SS ball filled, Inconel 625 vacuum vessel is employed. A comparison of calculations with steady-state plasma burn will be given.
