1.3 The ASN organisation for BNI supervision
All the tasks involved in supervising nuclear safety are split within the ASN between the DGSNR and the DSNRs. The DSNRs are entrusted with "on the spot" supervision. They are in permanent contact with the nuclear operators, take charge of most of the inspections carried out on the nuclear sites and provide step by step supervision of the various stages in PWR maintenance and refuelling outages, after which authorisation for restart will depend on the ASN. The DSNRs are also tasked with examining certain authorisation or waiver requests. The DGSNR is responsible for co-ordinating and steering the DSNRs in these areas, deals with all matters of national importance and defines and implements national nuclear safety policy.
1.3.1 BNI inspectorate

The BNI inspectors are ASN management level staff appointed from among the inspectors for installations classified on environmental protection grounds (ICPEs) by joint order of the ministers for the Environment and for Industry. Their supervisory functions are carried out under the authority of the Director General for Nuclear Safety and Radiation Protection. The inspectors are sworn in and bound by professional secrecy (see chapter 2 point 2.1.3).

On 31 December 2005, the number of BNI inspectors on duty stood at 156, including 78 in the DRIREs and 78 at the DGSNR. For the past 3 years, this number has remained on the whole stable. The list of these inspectors is given in Appendix A.
