Since 2000, CIEMAT (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas) is carrying out the PIMIC Project (Integral Plan for the Improvement of CIEMAT Facilities) for the decommissioning & dismantling of old nuclear and radioactive facilities and the potentially radiologically impacted areas and buildings. PIMIC activities involve the generation of waste materials with various physical, chemical and radiological properties, which must be characterized in order to be properly managed and comply with current regulations. Radiological characterization of these waste materials may lead to their classification as radioactive waste, in which case the “Plan de Gestión de Residuos Radiactivos del CIEMAT”[1] and their removal by ENRESA, the public company that manages the radioactive wastes generated in SPAIN applies [2, 3]. However, a large fraction of these waste materials with low radioactive contents are likely to be managed as conventional waste without further radiological control, through the so called Decommissioning Process. The optimization in the production of waste materials as well as their minimization are key factors for the process due to their significant economic, social and environmental impacts...
