Application of SEAFP waste recycling and clearance strategies to ITER

The long-term action of safety and environmental assessment of fusion power (SEAFP) of the EU fusion program investigates fusion power reactor design. SEAFP strategy for the management of activated material is here applied to international thermonuclear experimental reactor (ITER). This strategy aim s to reduce the amount of radioactive waste by conditional recycling (re-us e of the activated material) in novel fusion plants and by clearance (decla ssification of the material with low activity level to non-active waste). L imits on the surface dose rates of the activated material after an interim storage of 50 years are proposed here to define the suitable recycling proc edures. The possibility of clearance is assessed from limits on the specifi c activity of the material. These limits take into account the relative haz ard of the various radionuclides contained in the material. It is shown tha t the amount of permanent radwaste arising from ITER may be substantially r educed to 0. (C) 2000 Elsevier Science B.V. All rights reserved.
