Use this guidance to produce RRAs for all your transport activities that:
• Do not assess single package types( unless you only consign or carry single packages) but assess the number and type of packages you consign or carry together. You can consider bounding cases for routine transport activities involving a variety of radionuclides / packages
• Assess the full range of potential accident scenarios and do not rely solely on the robustness of a package type as justification that a potential accident is not possible
• Include calculation of potential accident doses or else provide a robust qualitative demonstration that an effective dose in excess of 1 mSv to any individual( drivers, emergency services personnel, employees retrieving the package and members of the public) over a period of one year following the radiation emergency is, or is not, possible
• Include a clear conclusion as to whether a radiation emergency is, or is not, possible and which type of emergency arrangements you are required to produce; CDG09 emergency plans for when radiation emergencies are possible( that also meet IRR17 Regulation 13 requirements) and IRR17 contingency plans when they are not
In practice, transport RRAs are no different from other RRAs that dutyholders are required to produce. By considering the matters required by paragraphs 70 and 71 of the IRR17 Approved Code of Practice in RRAs and following ONR guidance, transport dutyholders will have given themselves the best chance of ensuring their legal compliance.
SRP has produced a leaflet about Dutyholder Responsibilities when transporting civil Class 7 dangerous goods( radioactive material) by road, rail and inland waterways, which includes a handy flowchart.
