Management Strategies to Reduce the Radioactive Waste Amount in Fusion.

A waste management strategy for fusion activated materials aimed at reducing the amount of permanent nuclear waste is described. Three options are investigated: clearance, recycling and disposal as radioactive waste. Conditions allowing recycling are based on surface dose rates, those allowing clearance depend on the residual radioactivity, both ater 50 years of interim storage. Analyses are carried out on two power reactor designs, the SEAFP Model 1 (SM-1) and Model 2 (SM-2). The activated waste arising from SM-2, is 69000 t: 48% could be recycled, 39% cleared, 13% needs permanent disposal. The SM-1 activated waste is 58000 t. No waste should be disposed of, 70% could be recycled, 30% could be cleared. The presence of residual tritium within the waste has been considered. An alternative to V-5Ti recycling has been analysed, dealing with reprocessing of the alloy with elimination of noxious nuclides and subsequent clearance.
