The investigation into the technical cause of the incident has been concluded and reported to the Authority for Nuclear Safety and Radiation Protection (ANVS).
This investigation was conducted by URENCO, under supervision of the ANVS and with input from independent bodies. It has been concluded that the incident was caused by a chemical reaction as a result of a build-up of fluorine in a filter with trapping material. Measures have been implemented in all URENCO’s enrichment plants to prevent reoccurrence. The ANVS has approved restart of production, having taken three aspects into consideration: the investigation into the cause of the incident, the manner in which the consequences have been addressed and the procedure for restarting production. As part of our focus on continual improvement, we will maintain our review of processes and operations on all our sites.
