ASN Report 2017

321 ASN report on the state of nuclear safety and radiation protection in France in 2017 Chapter 11  - Transport of radioactive substances actual transport operation itself, for which no prior ASN opinion is generally required. This operation may however be subject to security checks (physical protection of the materials against malicious acts under the supervision of the HFDS at the Ministry for Ecological and Solidarity-based Transition). 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 9-metre drop, a compensatory measure may be to reduce the speed of the vehicle and have it escorted. The probability of a serious accident (and thus 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.
