1 Package Design Safety Reports for the Transport of Radioactive Material TECHNICAL GUIDE

2 Introduction Designof apackagefor thetramitisnecessarytodemonstrate compliance with national and international regulations. For package designs which need approval by a competent authority the documentary evidence of compliance with the regulations is the basis for the application for package. For packages not requiring competent authority approval the consignor shall be able to provide documentary evidence of the compliance of the package design with all applicable requirements.

3 Objective and Scope ThePDSRdocumentisintendedtoassistinthepreparationof the package design safety report to demonstrate compliance with the regulatory requirements. The PDSR provide guidance that covers package designs requiring CA approval (Type B, C, ) also covers package designs that not requiring competent authority approval (type A, Excepted Package IP-1, 2,3).

4 Objective and Scope The PDSR is based on the IAEA TS-R-1 Regulations, ADR, RID, IMDG code, ADN and ICAO respectively. The PDSR does not replace the regulations or limit their application, If there are any discrepancies between this document and the regulations, the requirements in the regulations apply. The PDSR does not relieve the package designer from any additional analysis need associated with the concerned specific package design.

5 Definitions The definitions stated in the IAEA TS-R-1 Regulations is applied throughout the PDSR document with some additional definition such as: Package Designer, controlled document, design drawing

6 Document Control Each individual document in Part 1 of the PDSR should be a controlled document and be approved for issue by the author/owner of the document and the package designer. Each individual document in Part 2 of the PDSR should be a controlled document and be approved for issue by a technical specialist responsible for the technical discipline being assessed.

8 PDSR Part-1 Administrative information Name of package and identification (serial number) Designer of package (name, address, contact details). Type of package. Modes of transport for which the package is designed and any operational restrictions. Reference to applicable regulations to which the package design is referring.

9 PDSR Part-1 Specification of contents Radionuclide / nuclide composition Maximum activity and concentrations Physical and chemical form, geometric shape, moisture content Special form radioactive material or low dispersible radioactive material, if applicable Nature and characteristics of the radiation emitted Limitations in heat generation rate of contents Mass of fissile material and nuclides

10 PDSR Part-1 Specification of packaging A list of packaging components with design sketch Materials of construction and closure devices (bolts, seals, etc) Containment and confinement systems, Structural components for thermal protection, Heat dissipation and shock limiting.

11 PDSR Part-1 Package performance characteristics To describe the main design principles and performance characteristics and that the package has adequate structural integrity to meet the safety requirements (e.g. containment, heat removal, dose rates, and criticality safety). to ensure that any subsequent decisions taken concerning changes to the package design due to manufacturing, repair, improved operation, etc include appropriate consideration of the possible influence on the package performance criteria and regulatory compliance.

12 PDSR Part-1 Compliance with regulatory requirements The Package Design Safety Report(PDSR) should include a complete list of all paragraphs of the international regulations and any other national regulations applicable to the respective package design.

13 PDSR Part-1 Operation The minimum requirements for the following activities should be fully defined for the packaging/package, as applicable (see PDSR annexes): Testing requirements and controls before first use and before each transport. Handling and tie down requirements Requirements for loading and unloading of the package contents. Requirements for assembling of the packaging components Supplementary equipment and operational controls to meet the regulatory requirements (e.g.: thermal barriers, duration limits, temperature limits, special stowage conditions ).

14 PDSR Part-1 Maintenance Requirements should be fully defined for Maintenance and inspection : before each shipment at periodic intervals throughout the lifetime use of the packaging/package.

15 PDSR Part-1 Management systems Specification of the management system including the quality assurance programme to ensure compliance with the relevant provisions for: Design, PDSR, documentation, records Manufacture and testing, Operation(loading, transport, unloading, storage in transit) Maintenance and repair.

16 PDSR PART 2 Detailed technical analyses to support the demonstration of compliance with the regulations.

17 PDSR Part-2 The Part 2 of the PDSR provide detailed technical analysis to support the demonstration of Compliance with the regulations. Reference to package design Acceptance criteria and design assumptions. Description and justification of analysis methods physical testing, results of previous similar design accepted, calculation or reasoned argument.. Analyses of the performance of package design to ensure safety requirements Comparison between acceptance criteria and results of analysis

18 PDSR Part-2 Structural analysis Technical analyses under normal or accidental conditions Assessment of the mechanical behaviour (including fatigue analysis, brittle fracture, creep ). Thermal analysis Assessment of thermal behaviour including an evaluation of thermal stresses, surface temperatures and the thermal behaviour Containment design analysis Assessment regarding the requirements for preventing the loss or dispersal or for limiting the release of radioactive material.

19 PDSR Part-2 External dose rates analysis The analysis should assume a maximum radioactive content with maximum dose rates at the surface of the package and at distances defined in the regulations. Criticality safety analysis For packages designed to transport fissile material not excepted from the requirements for packages containing fissile material, assessment of criticality safety for routine, normal and accident conditions of transport, for the isolated package and for the arrays of packages.
