摘要

The environmental concern and public perception as well as the steadily increase of the conditioning and disposal costs are pushing the nuclear sector to minimise the amount of radioactive waste. Hence it is a strong incentive to prefer the management option "recycling and reuse" instead of the option "disposal and replacement". The "recycling and reuse" option requires the availability of decontamination techniques as well as measuring techniques allowing to prove that the release criteria are met. Therefore SCK'CEN has now two decontamination installations for scrap metal on its own site. One installation uses a wet abrasive technique while the other one uses a chemical process based on the Ce4". These two installations, combined with the use of foundries for free release or for radioactive scrap metal recycling are now common practices at SCK'CEN and will allow to reduce the metallic waste to 10 % of the metallic scrap production and the costs at least by a factor 2.5.
