This book discusses the specifics of safety regulations regarding nuclear risk and the safety of nuclear installations. The author shows that (French) regulations concerning nuclear safety depend on maintaining a technical dialogue between the ASN, IRSN and nuclear operators. In the face of an ongoing European and global re-evaluation of the safety of nuclear power and alignment towards the Anglo-Saxon standard, the French approach may yet be able to make a significant contribution. This work will be of interest to all involved in nuclear power engineering and in the field of risk management and nuclear safety.
