Ascó Nuclear Power Plant (Catalan; Valencian: Central Nuclear d'Ascó, Spanish; Castilian: Central Nuclear de Ascó) is a nuclear power station located in Ascó, Catalonia, in Spain.
It consists of two PWRs of 933 and 943 MWe.
An INES level 2 incident occurred in November 2007 at the Unit 1 reactor. The Spanish Nuclear Safety Council (CSN) was not advised of the leak until April 4. Although the leak happened in November, particles were not detected outdoors until March 2008.[1]
CSN initially estimated that total radioactivity detected was about 235,000 becquerels. The council operating the plant later estimated that a maximum of 2.3 microcuries of radioactivity were spilled. CSN announced it was changing the classification of the leak from Level 1 to Level 2 because of "inadequate control of radioactive material and of providing incomplete and deficient information to the controlling body." An investigation was opened and the director of the plant was fired.[2] [3]
