Graph 5 shows the breakdown of significant events reported per notification criterion and Graph 6 presents their breakdown according to content and mode of transport. Causes of events The recurring causes of the significant events notified in 2024 include the following: ∙Radiopharmaceutical products delivery errors, with no real consequences, as the drugs delivered are appreciably the same. Most of them could therefore be used with no impact on patient treatment or on the environment. ∙Nonconformities affecting a package: they mainly concern deviations in the stipulations of the package model safety cases (notably, package stowage), or deviations in the conformity certificates. Labelling defects (error or omission) or signage faults could also be mentioned here. These events had no actual consequences for safety or radiation protection. ∙The presence of surface contamination spots slightly exceeding the regulation limits, detected in particular on conveyances which have been used to transport spent fuel packages (under-wagon water collection pans), or contaminated tooling, or on the outer surface of packagings. These events had very little impact on radiation protection of the public, who cannot have access to the contaminated areas. ∙Finally, cases where the regulation dose rate limit of the packages was slightly exceeded. These events had no actual consequences for the radiation protection of workers, the public or the environment. The EITs reported to ASN are primarily deviations relating to incorrect labelling of packages (consignee or consignor not mentioned), errors in the transport documentation, or deviations consisting in the detection of foreign objects in empty packagings. As for the on-site transport significant event notified, this concerns a lack of stowage instructions for transport of waste drums and crates in a new vehicle recently acquired. 4.3 Participation in drawing up the regulations applicable to the transport of radioactive substances 4.3.1 Participation in the work of the International Atomic Energy Agency ASN represents France on the IAEA’s Transport Safety Standards Committee (TRANSSC), which brings together experts from all countries and reviews the IAEA safety standards constituting the basis of regulations concerning the transport of radioactive substances. With a view to constant improvement of safety levels, ASN notably played an active part in drafting the 2018 edition of this document, SSR-6. The IAEA guide for application of the regulation of radioactive materials transport (SSG-26) was published in 2022. In 2022, ASN also supported the launch of a new revision cycle for SSR-6, submitting more than a hundred modification proposals to the IAEA in 2023 and 2024. 4.3.2 Participation in drafting of national regulations ASN takes part in the drafting of French regulations relative to the transport of radioactive substances. These regulations mainly consist of the Order of 29 May 2009 and the Orders of 23 November 1987 concerning the safety of ships and of 18 July 2000 concerning the transport and handling of dangerous materials in sea ports. ASN therefore sits on the CSPRT, which is called on to issue an opinion on any draft regulation for the transport of dangerous goods by rail, road and inland waterway. ASN is also consulted by the Ministry responsible for transport when a modification of the three Orders mentioned above can have an impact on the transport of radioactive substances.
