Asco Nuclear Incidents in 2008

On 5 April 2008 the Nuclear Safety Council (CSN) reported an incident in the nuclear plant of Asco. At first it was classified as level 1 on the International Nuclear Event Scale ( INES scale), but later the CSN decided to raise the incident at level 2 on 14 April by inadequate control of radioactive material and to provide incomplete and deficient information regulatory body. As a result the director and the head of the central radiation protection were removed.

It became public in May 2009 imposing a fine of more than 15 million euros by the Ministry of Industry as punishment for the incident.
