One of the main goals of research on fusion reactor materials is to develop low-activation alloys with good mechanical and physical properties. For this purpose, a clear definition of low activity is mandatory. Until now, the definition of low activity was based on waste management and disposal problems. A good low-activation definition, however, must consider not only waste management but also all the possible situations in which radioactivity may be a concern, such as accident and maintenance scenarios. A revision of low-activity limits is therefore necessary. In this paper low-activity concepts for fusion reactor materials and some application examples are presented.
