“Packaging” and “Packages” are terms of vital importance in Transport Regulations Package - The packaging with its radioactive contents as presented for transport Packaging - The assembly of components necessary to enclose the radioactive contents completely + = PACKAGING PACKAGE RADIOACTIVE CONTENTS Key Points: IAEA definitions and any related requirements and testing procedures must not be confused with terminology developed for operational or other regulatory requirements such as storage or handling of radioactive materials or wastes. A PACKAGE is defined (TS-R-1 §230 ) as a PACKAGING with its RADIOACTIVE CONTENTS as presented for transport. There are 8 basic PACKAGE types defined in TS-R-1 §230 There are only simple requirements relating to the PACKAGING component of the PACKAGES in the transport regulations (§606 - §616 TS-R-1). However, the transport regulations have a comprehensive graded series of requirements and tests for all PACKAGES (SECTIONS VI and VII of TS-R-1). The Type B(U), B(M) and Type C packages are tested to withstand extremely severe accidents without loss of contents. They are Competent Authority approved and normally licensed to carry a large RADIOACTIVE CONTENT. The other PACKAGE types listed in § 230 are only tested to withstand routine and normal conditions of transport (§106 TS-R-1). Consequently their RADIOACTIVE CONTENTS are limited so that any losses under accident conditions will present no significant hazard to workers or the general public.
Package Type Options for Transporting Radioactive Material Excepted packages Industrial packages Types IP-1, IP-2, IP-3 Type A packages Type B packages Type C packages Other (Fissile, UF6) Key Points: Explain that the package types, including unpackaged materials, addressed in this slide are discussed, in order, in this module. Briefly state the following: - Unpackaged materials are applicable to solids which qualify as LSA-I materials or SCO-I - Excepted packages are limited to a very restrictive activity, usually associated with limited quantities - Industrial packages are designed and tested to carry qualified, e.g., LSA materials and SCO, radioactive contents - Type A packages are restricted to carry contents up to a maximum of A1 or A2. - Type B(U) and B(M) packages are generally for contents with activities >A1 or >A2. - Type C packages are for transport of high content activity by air - UF6 packages are unique only to UF6 materials - Fissile material packages are specifically designed for the fissile material content and may include IPs, Type A, Type B, Type C and UF6 packages. Objective(s): None References: Module 7 Exercises: None at this point RAM classified as LSA-I or SCO-I may also be transported unpackaged - This presentation will focus on Type A packages
GRADED APPROACH TO TRANSPORT Package integrity is a function of the potential hazard of the contents and the response of a package under routine conditions of transport (incident free) – represented by general design requirements for all package types, normal conditions of transport (including minor mishaps) represented by Type A tests and accident conditions of transport (severe accidents) represented by Type B tests to assure the same level of safety for all types of packages Excepted Package Type A Package Type B Package
Hazards of the radioactive Material Safety functions of the Packaging Basic safety functions of packages for radioactive material Hazards of the radioactive Material Safety functions of the Packaging Radiation (α, β, γ, n-Radiation) Shielding Radiotoxicity (Contamination, Incorporation) Containment Heat release Heat transfer Criticality Criticality Safety 6
Concept of a Safe Package – Graded Approach The greater the hazard the stronger the package (Paras of IAEA Regulations TS-R-1, 2009)
Excepted Package Radioactive material in limited quantity (fractions of A1/A2) representing low hazard meets general design requirements to withstand routine conditions of transport Surface dose rate ≤ 5 μSv/h Only marking with UN number, consignor/consignee (mass > 50 kg) No competent authority (CA) approval necessary but the consignor must , on request, make available for inspection by the relevant CA, documentary evidence of the compliance of the package design with all applicable requirements

Scope of the Transport Regulations The Regulations apply to transport of radioactive material by all modes of transport on land (road, rail, inland waterway) on sea (maritime) In the air Transport comprises all operations and conditions associated with, and involved in, the movement of radioactive material; these include the design, manufacture, maintenance and repair of packaging, and the preparation, consigning, loading, carriage including in-transit storage, unloading and receipt at the final destination of loads of radioactive material and packages. Radioactive material is any material containing radionuclides where both the activity concentration (Bq/g) and the total activity in the consignment (Bq) exceed the values specified in Table 2 of SSR-6 59
Scope of the Transport Regulations (cont.) SSR-6 does not apply to radioactive material: that is an integral part of the means of transport moved within an establishment not involving public roads or railways implanted in or incorporated into a person or live animal In or on a person who is to be transported for medical treatment in consumer products having received regulatory approval, following sale to the end user SSR-6 also does not apply to: Natural material and ores containing natural radionuclides, provided the activity concentration that does not exceed 10 times the values listed in Table 2 Non radioactive solids objects with surface contamination levels ≤ levels defined in para 214 The regulations are not intended to apply to movements of radioactive material that form an integral part of the means of transport, such as depleted uranium counterweights or tritium exit signs used in aircraft. However, vehicles carrying density measuring devices for example, where the carriage is incidental to the use of the radioactive material do fall under the scope of the Regulations. Cardiac pacemakers are an example of implantation in persons. Another example is the case of people or animals treated with radioisotopes. Smoke detectors or luminous dials are examples of consumer products containing small amounts of radioactivity that are on sale to the general public in many countries. Such consumer products are only outside the scope of the Regulations after sale to the end user. Any transport between manufacturer, distributor and retailer is within the scope of the Regulations. The scope of the Regulations includes those natural materials and ores that form part of the nuclear fuel cycle or which will be processed in order to use their radioactive properties. The Regulations do not however apply to other ores which may contain naturally occurring radionuclides, but whose usefulness does not lie in the fissile, or radioactive properties of those nuclides.
Objective and basic safety concept The objective of these Regulations is to protect persons, property and the environment from the effects of radiation during the transport of radioactive material. This protection is achieved by requiring: containment of the radioactive contents control of external radiation levels prevention of criticality prevention of damage caused by heat
Basic safety concept applying a graded approach to These requirements are satisfied by applying a graded approach to performance standards applied to package designs contents limits for packages and conveyances depending upon the hazard of the radioactive contents imposing requirements on design and operation of packages maintenance of packagings considering the nature of the radioactive contents requiring administrative controls including, where appropriate, approval by a competent authority
Basic safety concept (cont.) Regulatory approach (SSR-6 para 106) A graded approach is applied in specifying the performance standards which are characterized in terms of three general severity levels: (a) Routine conditions of transport (incident free); (b) Normal conditions of transport (minor mishaps); (c) Accident conditions of transport. In summary safety is mainly assured by the package itself together with some control measures during transport and approval needs by the competent authority, where necessary 63
