► We focus on recent advances concerning fusion radioactive waste management studies. ► We examine activation of W and its alloys in W-based fusion components. ► We develop a management strategy for activated materials from complex components. ► We address the waste decay heat and maintenance questions. ► Public acceptance of clearable and recyclable materials may be a question. This paper focuses on a few recent advances and research developments concerning fusion radioactive waste management studies. In particular: the role of fusion power in the frame of the future production of nuclear radioactive waste, in terms of potential waste avoidance using a precautionary fusion waste management policy, activation of W and its alloys (examining and comparing the activation of W-based components in ITER, PPCS, and ARIES designs), development of a management strategy for activated materials from complex components (such as blanket and divertor), waste decay heat and maintenance questions, materials detritiation, and public acceptance of clearable and recyclable materials.
