Previous approaches to activated fusion waste management and disposal have considered recycling or shallow land burial (SLB) as suitable solutions. These concepts have influenced the development of low-activation materials for fusion (LAMs). European studies on fusion waste, however, concentrate more on disposal into geological repositories, while SLB does not seem a viable option. A classification of fusion materials into high-, medium- and low-level waste is proposed, taking into account contact dose rates and decay heat levels. This proposal is consistent with integral criteria to classify LAMs, based both on short-term (accidental releases and maintenance scenarios) and long-term radioactivity (waste management or recycling). Applications of the proposed waste classification to activated materials, as evaluated for fusion experimental (NET/ITER) and commercial (EEF) reactor designs, are shown.
