Safety Guide for Transport of Radioactive Material

DS554; SSG-26 (Rev. 2) Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (20XX Edition) Step 3 Agenda Item 3.1 TRANSSC 47 6 10 November 2023 Eric H. Reber, Transport Safety Unit

Background SSG-26 is a legacy safety guide that supplements SSR-6 SSG-26 supplements SSR-6 by providing paragraph by paragraph information on individual provisions including their purpose, safety basis, historical information and recommendations on how to comply with the requirements. At its June 2023 meeting, TRANSSC decided to remove the information that is not recommendations and guidance for meeting the provisions in SSR-6 and place it in other documents, such as: a Safety Basis Document ; DPP for this document will be considered at TRANSSC 47 (Nov. 2023); and an informational document that will include updated information from App. I on the Q System and the results of the work by the A1/A2 Working Group. A revision cycle for SSR-6 is ongoing and we plan to publish a revised SSR-6 by the end of 2025.

Justification To take account of the decision by TRANSSC at its June 2023 meeting to remove information about the purpose, safety basis, and historical information about requirements in SSR-6 from SSG-26, i.e. ensure consistency with the strategies and processes established in SPESS A. To account for changes to SSR-6 that result from the ongoing revision cycle Revision of SSG-26 (Rev. 1) is included in the Medium- Term Plan for the Safety Standards

Objective and Scope This safety guide will provide recommendations and guidance on how to comply with the requirements of SSR-6 (Rev. 2). It is intended that the application of the content of this safety guide will result in the harmonized application of the requirements of SSR-6 (Rev.2). The Scope is the same as SSR-6, i.e. all operations and conditions associated with the movement of radioactive material; all modes of transport are included This safety guide is intended to be used by competent authorities and users of SSR-6 (Rev. 2).

Interfaces with Existing and/or Planned Publications The proposed publication will be a specific safety guide in the group of safety standards on the safe transport of radioactive material. Other Safety Standards Series publications that have a direct interface with SSG-26 (Rev. 1) are: Regulations for the Safe Transport of Radioactive Material (20xx Edition), SSR-6 (Rev. 2) Schedules of Provisions of the IAEA Regulations for the Safe Transport of Radioactive Material (2018 Edition), SSG-33 (Rev. 1) Preparedness and Response for a Nuclear or Radiological Emergency Involving the Transport of Radioactive Material, SSG-65 Radiation Protection Programmes for the Safe Transport of Radioactive Material, TS-G-1.3 (under revision as SSG-86) The Management System for the Safe Transport of Radioactive Material, TS-G-1.4 (under revision as DS530) Compliance Assurance for the Safe Transport of Radioactive Material, SSG-78 Format and Content of the Package Design Safety Report for the Transport of Radioactive Material, SSG-66 Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards, GSR Part 3

Interfaces with Existing and/or Planned Publications (con t) IAEA publications that are not in the Safety Standards Series that have a direct interface with SSG 26 (Rev. 1) are: Security of Radioactive Material in Transport, IAEA Nuclear Security Series No. 9-G (Rev. 1) Managing the Interface between Safety and Security for Normal Commercial Shipments of Radioactive Material, Technical Reports Series No. 1001

Proposed Structure SSG-26 can only be used concurrently as a companion to SSR-6. As such, the structure of the body of the document will follow that of SSR-6 (Rev. 2) and the numbering of paragraphs will correspond to the specific paragraphs in SSR-6 (Rev. 2). One portion of an appendix and several entire appendices will be removed according to the recommendations of the Technical Basis Document Working Group (Report is attached to DPP). The TBD-WG recommended that the following portion of an appendix and several entire appendices of SSG 26 (Rev. 1) should be removed: Appendix I, The Q System for the Calculation and Application of A1 and A2 Values; It is planned that this appendix will be revised by the A1/A2 Working Group and published in a separate document. Table II.2, Dose and Dose Rate Coefficients of Radionuclides, of Appendix II; This portion of Appendix II should be removed as it is only relevant with regard to Appendix I. Appendix III, Example Calculations for Establishing Minimum Segregation Distance Requirements; Appendix III should be moved to the planned Safety Basis Document. Appendix V, Guidelines for Safe Design of Shipping Packages Against Brittle Fracture; Appendix V should be removed and included in another Agency publication, e.g. SSG-66, Format and Content of the Package Design Safety Report for the Transport of Radioactive Material or the planned Safety Basis Document. During the drafting of the document, consideration will be given to using hyperlinks to corresponding SSR-6 paras.

Proposed Structure (cont) Certain paras in SSG-26 (Rev. 1) provide guidance on topics that are also addressed by entire safety guides, i.e.: paras 301.1 to 303.5 of SSG-26 (Rev. 1) and SSG-86, Radiation Protection Programmes for the Safe Transport of Radioactive Material, both address radiation protection and radiation protection programmes paras 304.1 to 305.3 of SSG-26 (Rev. 1) and SSG-65, Preparedness and Response for a Nuclear or Radiological Emergency Involving the Transport of Radioactive Material, both address emergency preparedness and response paras 306.1 to 306.5 of SSG-26 (Rev. 1) and TS-G-1.4, The Management System for the Safe Transport of Radioactive Material, both address the management system. As SSG-26 (Rev. 1), SSG-78, SSG-86 and TS-G-1.4 are all specific safety guides paras 307.1 to 307.9 of SSG-26 (Rev. 1) and SSG-78, Compliance Assurance for the Safe Transport of Radioactive Material, both address compliance assurance There is no reason for the same topic to be covered in detail in SSG-26 (Rev. 2) and in another specific safety guide. During the drafting of the revision of SSG-26 (Rev. 1), consideration will be given to deleting the text on the topics listed above and instead, simply referring to the other safety guides.
