To this end, it submitted an authorisation application to ASN in July 2022 for multimodal transport of surface contaminated objects, known as “SCO III”. The 2018 edition of the IAEA’s international transport regulations, SSR-6, created this additional category of surface contaminated objects in order to meet the need for the transport of very large sized contaminated objects, resulting from installations decommissioning or the replacement of heavy components, such as steam generators. Owing to their dimensions, it is thus impossible to load these objects into a dedicated transport packaging. After completing the review of the application, ASN issued the first approval certificate for SCO-III shipment in July 2023. FIRST FRENCH APPROVAL CERTIFICATE FOR SCO-III SHIPMENT These approval certificates are usually issued for a period of five years. If a package is unable to meet all the regulatory requirements, the regulations nonetheless allow for its transport by means of a shipment under special arrangement. The consignor must then define compensatory measures to ensure a level of safety equivalent to that which would have been obtained had the regulatory requirements been met. For example, if it cannot be completely demonstrated that a package is able to withstand the 9m drop, a compensatory measure may be to reduce the speed of the vehicle, have it escorted and choose a route avoiding such a drop height. The probability of a serious accident, and therefore of a violent shock on the package, is thus considerably reduced. A shipment under special arrangement is only possible with the approval of the competent authority, which then issues approval for shipment under special arrangement, stipulating the compensatory measures to be applied. In the case of certificates issued abroad, the international regulations provide for their recognition by ASN. In certain cases, this recognition is automatic and the foreign certificate is directly valid in France. In other cases, the foreign certificate is only valid if endorsed by ASN, which then issues a new certificate. 280 ASN Report on the state of nuclear safety and radiation protection in France in 2023 • 09 • Transport of radioactive substances
