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 about sixty modification proposals to the IAEA in 2023. 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. Participants in the IAEA TRANSSC Committee No. 47 – 6 to 10 November 2023 The UX-30 is an overpack that surrounds a 30B cylinder filled with enriched UF6, in order to provide mechanical and thermal protection during the regulatory tests. The UX-30 is the subject of an American certificate that expires on 31 December 2024, which was validated by ASN in November 2019 and then again in December 2020. Approvals F/538/AF-96 (w) and F/538/AF-96 (x) issued by ASN expired on 15 November 2022. The Orano NPS company undertook to replace all UF6 shipments with UX-30 overpacks by shipments with DN-30 overpacks, no later than 31 December 2024, as the latter’s design is more recent and has also obtained the required approval certificate. Orano NPS asked ASN for a final validation extension of the UX-30 approval for an additional two years, to allow a transition between the UX-30 overpack and the DN-30 overpack, to ensure that a sufficient number of DN-30 can be manufactured. The validity of the two French approvals F/538/AF-96 (w) and F/538/AF-96 (x) was extended on 29 April 2022, with the addition of the following compensatory measures proposed by the licensees and accepted by the authorities of the European countries using the UX-30 overpack: • two 6kg powder or CO2 extinguishers are positioned on each side of the conveyance; • the drivers of the conveyance are trained in firefighting techniques, with training refresher courses at intervals of no more than two years; • the tunnels restriction code is B; • the conveyance is equipped with a geopositioning device, or a member of the crew is regularly able to communicate their position to the consignor and, as necessary, to the emergency services. The English, Belgian, Dutch and German competent Authorities also adopted these compensatory measures in their approval renewal processes.
