Radioactive particle dispersal at spain's asco-i in April was determined to be insignificant and is believed to have been limited to a small area or the plant site, but the lack of material control that led to the dispersal, and the inconsistency in the plant owner's reporting of the incident to regulators, drew attention in a country where there is already debate over whether nuclear power should be phased out. Asco-1, a 996-MWe pressurized water reactor in the state of Tarragona, was refueled last November, and it is believed that ventilation ducts in the fuel building were contaminated with activated corrosion products that were dislodged during the cleanup of the fuel transfer canal. On March 14, a radioactive metal particle was detected in front of the containment building's equipment hatch. More such material was detected later-cessentially all of it near the fuel building ventilation stack-with total activity of the released material estimated at 0.0023 curies.
