The strategy for handling fusion activated materials calls for three potential schemes: clearance, recycling and disposal. There is a growing international effort to avoid geologic disposal, for fusion in particular. Plasma facing components (divertor and blanket) normally contain high radioactivity and are not clearable. As clearance of sizeable components (such as biological shield, cryostat vessel, vacuum vessel, and some constituents of magnets) is highly desirable, we identified the source of radioisotopes that hinder the clearance of these components and investigated the impact of impurity control. Another study assessed radioactivity build up under repeated use of the divertor made of W-La
O
alloy. Effect of impurities on activated materials management is illustrated by the example of carbon-14 generation. Other studies examined impurities activation in concrete of biological shield and the impact of a specific activated materials scenario on the hot cell design and waste storage requirements.
