The decommissioning of a Nuclear Power Plant leads to the generation of a high volume of metallic waste, of which a large quantity can be recycled, after separating it from radioactive metal. The methodology that allows to separate radioactive metal from non-radioactive metal is an essential part of Decommissioning, and it requires complex equipment, procedures and controls, both inside Enresa and external (Regulatory Body). After undergoing these controls, most of the metallic material is sent to recycling facilities, where it is mixed with a much larger proportion of metal coming from conventional scrap yards, both here in Spain and abroad. In recent years, there have been a few incidents in melting plants, due to the presence of undetected radioactive material among certain batches of scrap metal. In order to tackle the public concern associated with potential risk, a series of measures have been designed to prevent these incidents or minimise their effects, should they occur. The following presentation will first describe the Spanish protocol established by different national institutions to prevent the presence of radioactive waste among the raw material for recycling, should this occur detect and control it, and secondly the methodology that guarantees that Enresa does not erroneously send radioactive material arising from the decommissioning of nuclear power plants to any smelting facility.
