Whenever it deems necessary, ASN seeks the advice of technical support organisations, primarily IRSN. The safety review implies cooperation by numerous specialists, as well as efficient coordination, in order to identify the essential points relating to safety and radiation protection. IRSN assessment relies on research and development programmes and studies focused on risk prevention and on improving our knowledge of accidents.
